Evaluate the Phosphorus Mobility in Soil Applying Organomineral Fertilizer and Mineral Fertilizer Phosphate.

The rearing of pigs and poultry has a large quantity of waste, which if not properly managed, have high pollution load to the soil, air and water. However, pig slurry and poultry can be efficient and safe fertilizers in crop fertilization, since it preceded the environmental assets to ensure the protection of the environment prior to its recycling. The objective of this study was to evaluate if the liquid fertilizer could allow the mobility of phosphorus in the soil profile. The experiment was conducted in the greenhouse on Lageado Experimental Farm in Botucatu, São Paulo State, Brazil. The experiment was arranged as a randomized complete block design (RCBD) of 5x5x1 with four replications. Where factor 1 referred to fertilizer type, factor 2 referred to doses of phosphorus and factor 3 the soil Psament. The treatments were: consisted of five types of fertilizers, 1 liquid organomineral (rearing of pigs), 1 liquid mineral (monoammonium phosphate – MAP + WATER), 2 solid mineral (monoammonium phosphate - MAP, triple superphosphate - ST) and 1 solid organomineral (poultry+ phosphorite), and five doses of phosphorus, 0, 50, 100, 200 and 300 mg dm^-3 of phosphorus. The plans were harvested 60 days after planting and was evaluated the soil in four depths. There wasn’t phosphorus mobility in soil depths.
