The purpose of this article is to describe new technical devices for differential application of fertilizers taking into account heterogeneity of the thickness of the humus horizon. Modern fertilizer application technologies are based on information obtained from agrochemical soil surveys, space monitoring data and the NDVI index. At the same time, all these technologies do not take into account physical and mechanical properties of the soil which influence soil fertility and productivity. The article presents data on the relationship between soil hardness and thickness of the humus horizon which have a strong inverse correlation of the -0.7-0.85 order. Based on these data, technical devices used for differential fertilizer application were designed taking into account power of the humus horizon. |
