Improving the understanding of phosphate fertilization in soil P content, acid phosphatase and production of sugarcane

The sugarcane crop is grown in large areas and has a productive chain of billions of dollars. In its chain, they are involved from sugar production to second generation hydrated alcohol. Phosphate nutrition is of great importance for culture, therefore requiring further studies. We sought to evaluate sources and doses of P in the absence/presence of filter cake. The first three models refer to P₂O₅ sources and doses in the absence of the filter cake and the last three models refer to P₂O₅ sources and doses in the presence of the filter cake (7.5 Mg ha^-1, in dry weight). As a statistical basis, we used average, median, maximum, minimum and standard deviation data for the variables evaluated.
