Use of information systems for monitoring soils and sows provides reduction of non-production expensesMore
The application of operational satellite monitoring in order to analyze agricultural crops opens up wide opportunities for companies to perform more efficiently.
From the time of the sowing campaign to the harvesting, agricultural producers more interested in crop conditions on the fields: how the culture is growing, the grain has matured, etc. In order to respond promptly to any risks arising in the development of crops, farm managers must have a reliable information about it. This will allow more effective coordination and control of the agronomic service, as well as making informed decisions.
Satellite monitoring of crops allows you to track the positive and negative dynamics in crops development. The difference in the dynamics of the vegetative index indicates a disproportion within the same crop or field, indicating the need for analysis or additional work in certain areas. A feature of this technology is that it allows you to simultaneously monitor the state of crops on a large area, to form a large statistical base for comparisons based on historical monitoring data.
We create products using space imagery of medium and high resolution from the satellites Terra, Aqua, Landsat, Sentinel: Terra and Aqua allow you to receive information twice a day, Landsat — once a week, Sentinel — every 10 days. A high autonomous level of crop monitoring processes provides management with operational information, and the interpretation of data in the crop status map makes it understandable for a wide range of users.
An important advantage of the created products is their verification on ground-based observations by comparison with ground-based measurements, agrochemical analysis data and indicators of crop development. Technologies are periodically refined through land survey campaigns — field visits and agricultural expeditions. In case of occurrence of an "anomaly" for each crop, the relevant specialist from holding receives a message on the basis of which the agronomists leave for a specific section of the field for photo-fixation and practical actions. Note that other ways of monitoring crops (for example, bypassing a car) are less informative and require more time and money. In addition, each observation is more difficult to organize and conduct than simply uploading historical data and interpreting it. Thanks to the satellite monitoring of the detours on the car no one will refuse, but these costs can be optimized.
OPPORTUNITIES FOR ANALYSIS
Having experience in conducting satellite monitoring of the crops conditions over an area of more than 300,000 hectares, we affirm that this technology allows us to observe during the year:
The results of the operational monitoring of the crop condition can be used to assess the impact of various negative factors. In fact, the farm or agroholding acquires a crops development history on specific fields during the season. Therefore, in connection with harvesting, the management analyzes in detail the causes of high or low yields, determines what exactly influenced the final result.
Historical data on the development of biomass are needed to create a land capability map. Such maps help to make more correct decisions about carrying out certain technological operations. In the case of integration with GIS systems regarding field passports and agronomists' reports on fields or integration with GPS monitoring systems on the fact of performing technological operations, the system allows for additional analysis of the performance of enterprises.
Forecasting yields for individual crops is carried out both directly from satellite observations and historical data on crop yields in this area over previous years and on the basis of more detailed biophysical models of vegetation growth developed by European scientists and implemented for the territory of the European Union by specialists of the scientific center Joint Research Center (JRC). These models are adapted for the Ukrainian territory and developed information technologies for assessing the state of farmland and forecasting yields.
The joint use of satellite data and models of vegetation growth makes it possible to evaluate the potential yield of a particular field and compare it to the real one, determining the ways and agrotechnologies necessary to bring real yields to potential possibilities. Currently, work is underway to create specialized services, in particular, pilot projects are planned with insurance companies that will be able to use satellite information to predict yields, as well as to identify real losses caused by possible natural disasters and adverse meteorological conditions.
Farmers will be able to track all the processes and changes that have taken place in the fields, and make appropriate decisions based on the analysis. Today in Ukraine, few domestic companies use satellite monitoring services for vegetation in crop production (although only agricultural producers with a common land bank over 150,000 hectares use our services). This all because of farmer’s conservatism and the relatively short period of existence of such a proposal on the Ukrainian market. On the other hand, domestic trends in the agricultural sector indicate that the next steps will be the optimization of assets and the search for sources of increasing the efficiency of their operation.
