eleagro service at a glance

eleagro has focused its activities on the empowerment of the Greek olive grower with technological innovation, so that he can produce more yield from his crop, reducing in parallel inputs (such as pesticides, fertilizers, energy and water), contributing essentially in the protection of the environment and natural resources savings. Remote sensing in precision agriculture is a rapidly developing trend. It is supported by the systematic evolution and progress of technology and guided from the recent necessity of agriculture for high productivity, reduced use of fertilizers and pesticides, so that agricultural production can feed more people with reduced cost.

eleagro and the partner group of experts of Geoanalysis S.A. with experience in remote sensing services and know how in agriculture are taking advantage of the tools that technology offers and provide services. Timely detection of Verticillium wilt is provided through the website using remote sensing means to the Mediterranean olive growers.

our values

The grower is the base of the economy worldwide, taking into account that he is working hard for covering the food, energy and clothing needs of human societies, based mostly on the natural resources (sun, wind, water). In parallel, the agricultural sector can be characterized as the biggest employer in the world, providing work, not only to the growers, but anyone involved in the production process, such as agricultural product retailers, food processors, transporters and dealers.

Thus, agriculture from its first appearance and up to its current form, caused significant changes in the human communities affecting their structure and organization. The value of agriculture for the mankind is certainly indisputable, taking into account that up to now it carries on being related to the formation and the operation of the human societies, rendering the people working in the agricultural sector an important part of their communities.

expertise & advisory

The expert team of eleagro works constantly to be able to provide to the grower advisory services for the olive growing, improving the quality of the services based on the modern trends and technological advancements, using of the most innovative means and equipment. eleagro services aim at guiding growers, so that the decision making and the undertaking of management measures to be based on the current expertise and the scientific results, and should not be based on the experience or random decisions.

Each grower in the world, independently of the growing commodity and the size or the location of the growing area, frequently needs agronomy services for applying the optimal management and plant protection measures in his field, ensuring the maximum output. Providing expert advice for crop management is becoming more and more necessary in Europe, where the new Common Agricultural Policy (CAP) of European Union will correlate grower subsidies with the implementation of sound agricultural practices for plant protection, irrigation and fertilization.

a different perspective

Through the eleagro remote sensing service, the grower is able to see his crop from a different perspective. The provided service is based on data processing and analysis acquired by high resolution sensors through Unmanned Aerial Vehicles (UAVs) or satellite, depending on the needs. The final product is a reference map of the crop status sent to the grower. More specifically, the grower may receive information for water stress and pest and diseases infection mapping within the field, through colored images accompanied with the appropriate interpretation.

Thus, for instance, in case of water stress, the grower is able to know where it is located within the crop, at which extent and the cause (i.e. Verticillium wilt stress), while in parallel he is provided with management advice. As a result, a digital map converts to a useful tool for providing information for the application of management practices and the increase of productivity.

olive: problems & solutions

the olive tree

The olive (Olea Europaea) is an evergreen tree that can live for thousands of years, with edible fruit. The longevity of this tree is its most characteristic attribute, while it is equally important that it can maintain significant productivity for centuries. There is no need to mention the importance of the olive crop for our country, since it is related to its history, rural economy, local inheritance and the environment. It is known to all of us that the ancient Greeks were crowned an olive wreath (kotinos) as a prize for winning the ancient Olympic Games.

The importance of the olive for the Mediterranean Countries is due to the fact that the olive has developed and can thrive in two narrow strips in the temperate zone (30ο-45ο), which include the Mediterranean basin. The olive oil is considered the best from all the oils and is recognized internationally for its pleasant aroma. In Greece, the olive orchards occupy 75% of the areas established with production trees and 1/3 of the rural population of this country deals with the olive growing.

nutrition

Fertilizer application should be based either on soil and plant analysis or remote sensing. Olive is a fruitful tree and, as it is known, all the fruitful trees have high requirements in nutrients, despite that there is a misconception that this is not true for olive, because it has a rich root system able to explore a big volume of soil. This is the reason why the olive presents adaptability in very different environments, and even in environments with marginal soil conditions. However, this is not the reason in any case to allow the tree living under deprivation, because this tree, when inadequately fertilized, can follow a biennial cycle of production (alternate bearing of olive), that is a productive year can be followed by a year without production. For this reason, a constant monitoring of the nutritional status of the tree is required, so that plant deficiency can be avoided, which can lead to the waste of all the effort Invested for the year (cropping practices, pruning, plant protection), since the tree productivity would have been wasted for this year. Apart from that though, the management of the nutritional status of the tree is particularly important for the management of Verticillium wilt in the olive orchard, as trees oversupplied with nitrogen can develop excessive vegetative growth, and, as a result, the growth of this pathogen can be favored within the plant. Apart from the nutrient deficiency, the excessive vegetative growth is also another reason of alternate bearing of olive.

olive orchard & remote sensing

what is remote sensing

Remote sensing is the acquirement of information for an object without having physical contact with that, either through a satellite or using Unmanned Aerial Vehicles (UAVs) with appropriately adapted sensors. The science of remote sensing, taking advantage of the high technological advancement occurred on this field, either considering the sensors and the equipment or the evolution of methods and algorithms, can become an important tool towards the improvement of the competitiveness of the Greek agriculture, through the reduction of inputs (reduced but targeted applications for plant protection and fertilization), the improvement of the quality of agricultural products (avoiding residues of pesticides in food) and the protection of the environment.

new perspective

The application of precision agriculture methods is now possible through the eleagro service and constitutes a successful alternative, more economic, more flexible and less laborious methodology compared to the traditional field sampling procedures from the ground. Thus, the agronomist or the grower can have access on the information he wants for his crop from a digital image through his computer in his office, instead of collecting the required information from the field. The most important advantage of this method has to do with that the grower can now focus on the part of the field which needs management (infected areas, nutrient deficiency in the crop, crop strips having water stress, weed growth, faulty irrigation equipment within the field) and thus reduce the effort needed to undertake for dealing with the cropping problems, and, also, reduce the use of pesticides, fertilizers, water and energy. The above mentioned result in the reduction of crop production for the grower, increasing the competiveness of his products through the reduction of the inputs and his contribution to the protection of the environment.

precision agriculture and remote sensing

Precision agriculture in one sentence is the targeted application of better management practices (precisely) on specific parts of the field through precision measurements and application of remote sensing techniques using images from modern sensors. The importance of precision agriculture is lost quite frequently today between the modern and advanced equipment, the complexity of applying the precision agriculture methods and the required level of knowledge to implement these methods. The reality is that we want precision agriculture, but this has to be provided through a practical and flexible tool, which could rapidly provide us with information and be translated easily in management practices. Thus, precision agriculture cannot be implemented in practice if there is one element missing on the triptych: information – technology – management. The eleagro group analyzes and process information taken by advanced sensors and platforms (satellites, unmanned and manned aerial vehicles) and translates them in management practices (Verticillium wilt management strategies, sound fertilization of nitrogen, etc.). In parallel, the grower is supplied with «recipes» of Verticillium wilt management.

NDVI index example 

The normalized Difference Vegetation Index (NDVI) is the most known index of remote sensing with application in agriculture and used for vegetation stress mapping. Using the NDVI we can map the different stages of stress in the field (before they become visible by the naked eye) and treat them for controlling what caused the stress, and finally prevent yield losses. Many times, if the stress becomes visible by the naked eye of the grower, a reduction of plant productivity is inevitable and even worse, if there is Verticillium wilt growth within the plant, plant losses are also possible.

verticillium wilt management

Olives and olive oil are our country's main export commodities. Thus, the management of the most serious disease of olive, that is Verticillium wilt, can contribute significantly to the reduction of damages caused on the plant capital and becomes very important.

The management strategy of the fungus can be achieved with a schedule of root watering and spraying. After the infection of the tree, fungicide applications, even systemic, cannot be efficient. Today, the management of the fungus is possible with the aid of a special program of root waterings and foliar sprayings using biophysical products. However, the speed of bringing back the trees in full productivity depends on their level of infection. Thus, the combination of timely diagnosis and management using root waterings and sprayings can prevent yield losses.

during the season

The problem of Verticillium wilt is more intense in areas cultivated with table olive varieties and even worse in irrigated areas.

Resistant olive variety to Verticillium wilt does not exist. There is increased susceptibility to the disease though for some varieties compared to others. The most susceptible varieties are Amfisis (cultivation areas: in Central Greece, such as Aitoloakarnania and Magnesia) and Chalkidiki (cultivation areas: Northern Greece, such as Chalkidiki, Pieria, Kavala and Drama) and less susceptible is Kalamon (cultivation areas: mostly Peloponnese, but in small areas this variety is spread in the whole country).

The varieties grown for olive oil production present also susceptibility to this pathogen, however, the infection from the fungus is inhibited mostly from the cropping practice (non-irrigated olive crops).

The pathogen is generally active in autumn and until the beginning of winter, while it reactivates at the end of winter to the beginning of summer. Many times, it is favored by the calm winters, which follow a rainy spring. The symptoms from Verticillium wilt infection become evident mostly in spring and summer (particularly during the period of flowering and fruit setting).

The management of the infected trees can become using special products, through the root watering practice. The first root watering has to be applied from the end of winter to the end of April. The second root watering has to be applied from the end of summer to the end of October.

Is there reduction of olive yield due to Verticillium wilt?

Each olive grower knows that the yield of the olive orchard can be affected significantly from the most important disease of the olive, which is called Verticillium wilt and is characterized as the HIV of olive. Verticillium wilt is the most important factor of yield reduction in the olive growing because it causes plant losses. The appearance of this disease increases with high intensity and severity in many olive growing regions of the country, due to the intensification of the olive growing and the disease transmission because of non-using appropriate cultural practices. The fungus establishment in the xylem of tree, which is the ascending supply system from the root to the canopy, leads in stress of the infected tree or branch. The result can be so serious that even entire branches of the plant or the entire tree can die in one growing season. The infection symptoms progress gradually until the entire wilting of the branch or the tree.

Is it possible to detect the disease at first stages with visual observation (eye inspection)?

The detection of the disease with the eye is very difficult at the early stages of the infection. It is though very important to detect the disease at early stages because in this way the management cost of the fungus and the probability of yield reduction are reduced. With the recent level of methodology available for the identification of the fungus in the field, either an experienced plant pathologist should detect the pathogen in the field with visual observation or the fungus should be detected using laboratory techniques, such as in vitro cultures or molecular techniques. All these methodologies are expensive and, furthermore, they cannot provide spatial information for the precise location of the fungus in the field.

Is there an alternative means of reliable detection of the disease at early stage, when it is difficult to be detected with the eye?

eleagro service has developed a diagnostic tool to detect timely the problem of Verticillium wilt in the field, using remote sensing means. The digital mapping of the field parcels with remote sensing methods is a cutting-edge technology for the modern agriculture, for which precision agriculture techniques are expected to be applied, and provided as a digital service by eleagro. Today, it is necessary to look for diagnostic methods which should give specific quality information for the problems that the crops are facing (stage of plant pathology infections), but also spatial information (location of the plant pathology problems within the field), so that targeted applications and treatments to be recommended. 

What is the product that grower receives on his hands from the eleagro service?

The grower receives on his hands a map and a report. The field is displayed in the map as an appropriate color image through which the levels of stress within the field are defined spatially. The spatial representation of stress through a color scale (that is the areas of the field parcels requiring treatment are presented through the map) is explained in the report that the grower receives along with recommendations of the treatment for the stress. Thus, the digital imaging converts in valuable information for application of specific management practices for the grower. 

What is the digital imaging of a field through remote sensing?

The digital imaging of the field allows the mapping of stress, so that the grower can restrict it or eliminate it, through management practices which are also recommended to him. Thus, the grower receives an image or more (depending what he has asked to examine in his field, i.e. nitrogen, water or disease stress) and a report with management recommendation for the factor causing the stress. The big advantage of remote sensing is that the potential of collecting information and data from large agricultural areas within short time is provided and thus it is a much more productive method of sampling and financially sound compared to the traditional procedures of sampling in the field. Thus, the grower can increase the yield from his field, while in parallel will reduce the inputs (pesticides, fertilizers, energy and water).

Which benefits can a grower realize from remote sensing?

Remote sensing is the science of observation and detection of a phenomenon remotely, that is through images which are received from remote sensors. Remote sensing, and its products offered through appropriate processing, find applications in many areas. More specifically, in the agricultural sector remote sensing can provide information for the status and the distinctive features of a crop. Each plant has a different spectral signature (differ in the reflectance and the absorbance of the incident irradiance) and through the calculation of spectral indices specific characteristics of the plants can be detected. More specifically, the application of remote sensing tools and methods provides the potential of vegetation stress detection in the field, but also the detection of the cause of this stress. 

An advantage also of remote sensing is that its products are georeferenced taking advantage of global positioning system (GPS) measurements and can be incorporated in geographic information systems (GIS). This provides the potential to the grower of knowing the precise location of the problem (i.e. Verticillium wilt infection, nitrogen deficiency, faulty fertigation equipment, water stress, weed detection), and thus dealing with it easier. The knowledge of the size and the location of the problems increases the yield of the olive orchard, reducing the management practices (reduced sprayings and fertilization only where needed, etc.), the water use (because of the targeted repair of the irrigation system or the targeted application of water on plants suffering by water stress) and finally energy consumption due to the use of agricultural machinery only in the areas needing treatment. 

Do I need to have knowledge in precision agriculture to be able to use remote sensing?

Absolutely not. Remote sensing follows a procedure which requires many steps until the final result is achieved: aerial vehicles, satellites, extended experimental data from the field so that remote sensing information can be interpreted, algorithms and correlation equations of the reflectance values with infections, diseases etc., management practices coming after long time experimentation, measurements and spatial correlation techniques of the images, lab techniques of pathotype identification etc. All these though have to do with us.   

What is the procedure to use the eleagro service?

For the grower, the procedure is absolutely simplified. He has to follow four steps: a) he is registered in the service, receives a personal password and is logged in, b) he chooses through a digital map the area where his field parcel is found and we undertake the application of the remote sensing diagnostic tool, c) using the same password that he was given to log in and choose the area where his field parcel is found, he is logged in after he has informed through e-mail that the diagnosis in his area has been conducted and downloads the data and finally d) receives a report with digital images and recommendations practices (a spraying schedule, fertilizer recommendations, fertigation scheduling, recommendations for repair of faulty irrigation equipment etc.) which can discuss with the support group of consultant agronomists of the company.

In parallel, the grower can download in his tablet, his smartphone or his computer the software, which is provided to him by the company, with which he can see the digital map with color scales for the level of stress and the level of management required. 

How can I see an example of the eleagro service?

Under construction

When should plant analysis be conducted, relatively to the olive nutrition?

Generally plant analysis should be conducted in close time intervals (every two years), unless there are remote sensing data, which detect nitrogen deficiency or sufficiency, and thus, in this case, plant analysis should not take place so frequently.

How are the samples for plant analysis taken?

Separate plant analysis samples should be taken from areas of the field parcel where different varieties are grown, having soils with different properties, different irrigation systems are applied, different microclimate or soils having different slope. In these cases, remote sensing facilitates the grower significantly, because image acquirement takes place for the whole field parcel and the information extracted refers to the total area, enabling the calibration of sufficiently supplied zones of the field parcel compared to deficiently supplied zones. Plant analysis also requires that no sample is taken by tree not growing well (that is a tree which is infected by a disease or pest) and thus the grower fertilizes the tree based on the sample taken from the rest of the field (thus he applies uniform fertilization). On the other hand, by using remote sensing, the status of each tree in the field is provided and fertilization is adjusted on the natural variation of the field, but also on the requirements of each tree separately, according to its age, physiological status, productivity, location etc.

Which is the best period for plant analysis sampling and how is the sample taken?

The end of the growing season, which is after fruit harvest, is the best time to take a plant analysis sample, because at that time nutrient concentration stabilization in the olive leaves takes place. The leaves for the sample are taken from the middle of healthy current year’s branches and average vigorousness of the size of 30-50 cm, which do not bear fruits. In order to have higher representation in the sample, the leaves collected should have come from as many as possible trees within the field parcel. The leaves should be closed in paper bags (for maintaining in the sample high moisture) and sent to an analytical laboratory through mail within no more than 3 days.   

Is the management of Verticillium wilt disease possible in olive orchards?

There is a root watering and sprayings’ recommendation schedule which indirectly achieves integrated management of the olive orchard through the reduction of excessive vegetative growth of olive and thus prevention of Verticillium wilt. The sound nitrogen management also using remote sensing provides increased yields, reduction of nitrogen fertilization and thus financial profitability and environmental protection through the reduction of nitrate leaching. 

Is there a relationship between nitrogen deficiency and Verticillium wilt of olive?

The detection of nitrogen deficiency and nitrogen fertilization recommendation leads indirectly in the integrated management of the olive orchard through the reduction of excessive vegetative growth and thus in the prevention of Verticillium wilt. Sound nitrogen management using remote sensing also leads to increased yields, reduction of nitrogen fertilization, and thus in the reduction of cost production, and in the environmental protection through the reduction of nitrate leaching.

Nitrogen is the most important macronutrient and in case of deficiency can lead to yield losses. In parallel, while it is necessary in higher concentrations compared to other nutrients, it is the most mobile element in the soil with its nitrate form. Thus, the excessive use of nitrogen can lead directly in income losses for the grower, since the nitrogen fertilizers are one of the basic inputs in farming, but also indirectly due to the reduction of production (diseases, excessive vegetative growth etc.).

The traditional procedures of nitrogen requirements monitoring include soil nitrate analysis, plant analysis and total nitrogen analysis or nitrates in plant tissue, chlorophyll content meter and finally lysimeters established densely within the field. These procedures though are time consuming, laborious, and require careful sampling so that the sample is representative and are referred to a mean of 10 stremmas area, and, thus, the soil variation within the field parcel cannot be determined, which is anyway large and changes from meter to meter. Thus, they lead in a uniform management of the field parcel eliminating for the grower the possibility to define uniform management zones (i.e. some trees within the field which need more nitrogen and some other trees which need less nitrogen) and finally save money from the sound management of nitrogen. Remote sensing acquires information from the whole field parcel, looking the field as a single sample and, thus, can define the variability that is the non-uniform variation of nitrogen within the field parcel.

Nitrogen deficiency detection


April 16, 2014
articles

Nitrogen deficiency detection and nitrogen fertilization recommendation leads indirectly in the integrated management of the olive orchard through the reduction of the excessive vegetative growth of olive and thus in the prevention of Verticillium wilt. The sound management of nitrogen also using remote sensing results in increased yields, reduction of nitrogen fertilization and, thus, economic profitability and environmental protection through the reduction of nitrate leaching.

Nitrogen is the most important macronutrient and in case of deficiency can lead in yield losses. In parallel, while it is required at higher rates compared to the other nutrients, it is the most mobile in soil through its nitrate form. Thus, excessive nitrogen application can lead in income losses for the grower, since the nitrogen fertilizers are one of the basic inputs in farming, but also in income losses indirectly through the reduction of production (diseases, excessive vegetative growth, etc.).

The traditional procedures of nitrogen requirements monitoring include soil nitrate analysis, plant analysis and total nitrogen analysis or nitrates in plant tissue, chlorophyll content meter and finally lysimeters established densely within the field. These procedures though are time consuming, laborious, and require careful sampling so that the sample is representative and are referred to a mean of 10 stremmas area, and, thus, the soil variation within the field parcel cannot be determined, which is anyway large and changes from meter to meter. Thus, they lead in a uniform management of the field parcel eliminating for the grower the possibility to define uniform management zones (i.e. some trees within the field which need more nitrogen and some other trees which need less nitrogen) and finally save money from the sound management of nitrogen. Remote sensing acquires information from the whole field parcel, looking the field as a single sample and, thus, can define the variability that is the non-uniform variation of nitrogen within the field parcel.

Timely detection of Verticillium wilt (Verticillium dahliae) of olive

Verticillium wilt of olive is a vascular disease (causing blockage of the xylem vessels) and is caused by the fungus Verticillium dahliae, for which it is believed up to now that there is no treatment. Eleagro team develops a diagnostic tool for the timely detection of Verticillium wilt symptoms using remote sensing digital images acquired by satellite and unmanned aerial vehicles.

Through eleagro, the possibility of detecting the infected trees at stages which are not visible with the eye (which are the most sensitive for the timely management of the fungus) is provided, and, in parallel, a "recipe" (recommendation) is given for the treatment of the disease, so that it can become manageable and the yield reduction be prevented. More specifically, eleagro can offer a recommendation program of root waterings and sprayings, which after long time experimentation has been proven to be able to manage the fungus.
