Soil fertility parameters evaluation for implementation of differentiated fertilization
Keywords:
coefficient of variation, differential fertilization, soil heterogeneity, statistical analysisAbstract
In the work was to evaluate the expediency of using differential fertilization on the soil fertility indicators of chernozem podzolized, and also to determine the share of influence of factors that limit the effectiveness of technologies for growing winter wheat, maize for grain, and soy. For indicators of soil fertility of chernozem podzolized, the expediency of using differential fertilization was assessed, the share of influence of factors that limit the effectiveness of technologies for growing winter wheat, corn for grain, and soybean was determined. It was established that the yield of winter wheat on chernozem podzolized had a close direct relationship with the content of mineral nitrogen compounds in soil (52%), maize for grain with mobile phosphorus compounds (55%), soybean with agrophysical indicators (51-62%). For the coefficient of variation of agrochemical parameters in the chernozem podzolic, which was 21-58%, it is expedient to apply a differential of nitrogen, phosphorus and potassium fertilizers.References
