ABSTRACT: The use of organic waste in agriculture has been
used aiming at greater productivity, decrease in the cost of production and
sustainable use of resources. The present study aimed at evaluating the effect
of phosphate fertilization with the maintenance of organomineral fertilizers,
combining poultry manure and soluble or reactive phosphate, in the production
of grains in corn culture and the residual effect for subsequent crops of beans
and soybeans. The experiment was conducted in Sete Lagoas, MG, in 2015, using three fertilizers with sources of different phosphorus
sources (triple super phosphate—STP, organomineral with STP and organomineral
with Bayovar phosphate) applied at the doses of 65, 130, 195 and 260 kg·ha¯1 of P2O5 total, and compared to the control without
phosphate fertilization. We evaluated the contents of foliar P, P accumulation
in the grains, yields of corn grains, beans and soy, accumulated productivity and export of accumulated P of
the three cultures. The three cultures assessed presented higher
productivity when compared to the average of the factorial treatments that
received phosphate fertilization relative to the control. Organomineral
fertilizers increased grain production, obtaining average productivity equal to
or greater than those obtained with the exclusive use of STP.
