Caracterização de um mecanismo dosador helicoidal de fertilizantes sólidos.

Abstract

The great part of agriculture production costs in Brazil is function of fertilizer application. However, fertilizer mechanisms can give a no uniform application or an application that not correspond to the manual. The excessive in fertilizer application can be damaging to crop, to the environment and product’s waste. The lack can make an increase in productivity. The objective of this work was characterizing an helicoidal fertilizer distributor. Tests were made to define the power demand necessary to run the fertilizer distributor and the application rate by engine rotation shaft curve. The equipment showed a linear application rate and didn’t demand a great power to operation, so it was adequate to control’s variable rate systems application.
