Organomineral fertilizer is an agronomic efficient alternative for poultry litter phosphorus recycling in an acidic Ferralsol.

The objective of this article is to evaluate the agronomic efficiency of organomineral fertilizers in supplying P to soybean and maintaining the soil P level of a Ferralsol as a strategy for poultry litter P recycling in a 6-year field experiment in the Brazilian Cerrado region. We further investigated the effect of legacy P or residual P on soybean yield after several years of soil P fertilization
