Formation of the regional network testing trail in the soil fertility monitoring system of agricultural land
For the first time the experiment of the regional test sites network formation in the monitoring system of soil fertility of agricultural land was conducted in the Leningrad Region and also adopted to Russian conditions. The network makes possible to get an objective assessment of the soil cover condition, as to prevent the environment pollution by chemicals, to improve the quality and safety of agricultural products. The developed monitoring system and the methodology of constructing a hierarchical system for monitoring the land productivity provides an increase of the changes informativity based on the experimental and technological basis of precision agriculture.
