Avaliação da segregação de dois fertilizantes aplicados a lanço.

Abstract

Machines frequently used for spreading of fertilizer and limestone, has as a primary caracteristic, high dependence related to the quality and physical condition of the product to be distributed, so the target of this project was verifying the distribution of grain and constance on the aplied formulation througout of the spreading width of a spread machine with two fertilizers. The results indicate that both fertilizers showed some diferences on the formulation considering the distance from the trowning position to where they were collected. The formulation which had the micronutrients had the larger degradation to the aplied formula and its segregation was it considered the elements of the formula. It was verified that, by the results of the individual effective spreading widths of each element that values for micronutrients were lower, showing a worse distribution for them.
