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

<p>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&nbsp;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.</p>
