Data Use of Satellite Imagery in Precision Farming

Abstract

The article focuses on the use of space imagery data in order to implement precision farming systems. It should be noted about the need to implement the remote sensing and geographic information system principles in agricultural activities and modern aggregates. The satellite imagery data have already been used by the advanced countries of the world for the purpose of dosing fertilization and that has a positive effect on the environmental safety and saves money on expenses during agronomic activity. The article notes that you can quickly and reliably estimate the heterogeneity and the structure of soil cover of each field with the help of satellite images, if during the shooting the field surface was not covered with vegetation, or agricultural vegetation was in the first stages of vegetative development. The heterogeneity of the spatial distribution of nutrients in the fields can also be assessed by agricultural vegetation with decoding features images of satellite imagery. The nutrient content of the soil (amount of nitrogen, phosphorous, potassium, humus, iron) and their horizontal redistribution within the individual fields can be evaluated not only by space images, and on the basis of digital cartogram of these elements, which are made on laboratory analytical data, digital elevation models and other information.
