Utilização de coletores alternativos para ensaios de distribuidores de fertilizantes e corretivos

Abstract

One of the operations for the good conduct of a cultivation is the distribution of fertilizers, wherein the uniformity of this application is an important factor in the efficiency of the operation. In the distributors, the flow and working width are common adjustments, but the tests of working width and uniformity of distribution are less used by the producer because it requires lengthy procedures. Considering this, this work had as objective to evaluate alternative collectors for solid products and also to obtain the useful width of work, in order to make this procedure more accessible to the producer. The work was conducted at the Federal University of Mato Grosso, in the courtyard of the machine laboratory. Three types of collectors were used: cardboard box, shoe box and wooden box. The collocation of the collectors was done side by side, so that they reached the full application width of the distributor. A 77.2 kW agricultural tractor was used, in which the distributor of fertilizers and agricultural corrective, of trawl, model DCA 2500, brand Tatu Marchesa. The effective working width obtained for the coefficient of variation of 15% was 10m or less. The collector that obtained the best performance was the wooden box, considering that the collectors were approximately the same height, the collecting area was the most important factor for its efficiency.
