Plant Protection, Fertilizing and Irrigation Fertilizing

With about 4000 l the container volume of tractor mounted centrifugal fertilizer spreaders reached a maximum. Methods to combine sowing with fertilizing and processes for a fertilizer placement in the soil are in development. GPS-controlled schematics for an optimized distri-bution accuracy are introduced into practice on a large scale. By fast and convenient inform-ing of the operator and by automated or significantly simplified inspection of the spread pat-tern, the technically possible should be put into practice. Furthermore the efficiency of the entire process is increased by integration of fertilizing in management-systems.
