Calculating Nitrogen Fertilization through a Mathematical MODEL for GRAIN Sorghum CROP.

Nitrogen fertilization for crops are, still now, a bit difficult to define. It is truth that a lot of factors have to be considered for formulating an amount of nitrogen that a crop needs in order for reach its maximum yield under given local conditions. Soil, temperature, water availability and light are mayor factors that have to be considered for calculating the amount of nitrogen needed for a sorghum grain crop. A mathematic equation was defined for calculating nitrogen fertilization for México sorghum grain crops.
