Effect of biosolids on the nitrogen and phosphorus contents of soil used for sugarcane cultivation
Jorge Antonio Silva–Leal, Andrea Pérez–Vidal, Patricia Torres–Lozada
Abstract
. Biosolid treatments exceeded the phosphorus requirement for sugarcane cultivation by up to 277% for B, 170% for BST, and 368% for BA. The application of biosolids sufficient to meet crop nitrogen requirements significantly increased soil phosphorus content, suggesting an overdose and low crop response to the available phosphorus. The application of biosolids yielded results similar to those of mineral fertilizers, suggesting their potential use in agriculture.
