Redução da evaporação de gotículas para pulverizações agrícolas.

Abstract

The factors that exert influence in the resistance to traction offered by the plow are considered so that th ey might be compared w ith the tractive forces exerted by tractors , less the loss of power due to local conditions and to reduction in force due to declivity and rolling soil coefficient . There is a group of variable elements that exert influence in the final valnes obtained , turning calculations very extensive: nevertheless , in view of the use o f modem calculators or even computers, the calculation has become faster , enabling the operator to elaborate tables that allow their use for a correct program for the use of plows. Once such values are obtained the tractors minimum power are calculated , considering the periods (hours) for the plowing of the various areas .
