INCREASING THE EFFECTIVENESS OF SPRAYERS FOR LIQUID MINERAL FERTILIZERS APPLICATION
The main trends of using the on-ground (hinged, trailed, self-propelled) sprayers produced by the AMAZONEN-Werke (Germany) company and its plant in Russia JSC “Eurotechnika” (Samara) for liquid mineral fertilizers (LMF) application are considered in the article. It is shown that the use of field sprayers with corresponding supplementary equipment (pulverizers, reinforced pumps, etc.) is rather effective for application of liquid mineral fertilizers. The AMAZONE Co., producing a large range of field sprayers, is the leader in the production of trailed farm machinery in Russia (“Eurotechnika” JSC, Samara). The authors have systematized the existing nomenclature of above field sprayers and have constructed nomograms of their performance for one refueling, depending on the units' capacity. The recommendations on the selection of the most effective sprayers for each specific agro-enterprise have been developed. The nomograms showed that the trailed sprayers for the LMF application were the most effective ones, with the UX-11200 sprayer, capable to apply 11200 liters of liquid fertilizers at the area of 112 ha, with one refueling, or the operation of the unit within 3 hours, which is enough to deliver a new batch of fertilizers, without stopping the unit and reducing its performance capacity.
