Conteúdo: |
Production of organomineral phosphate fertilizers (OMF) from poultry litter (PL) has been suggested to reduce
the dependence on phosphorus (P) reserves. Here, we compared a granular PL-derived OMF to triple superphosphate
(TSP) in two contrasting tropical soils (Oxisol and Entisol) by using isotope dilution with 32P. Our
study aimed to gain insight into soil P fractionation, and P availability to maize plants achieved by P fertilization
(0, 25, 50, 75 and 100 mg kg-1 of soil), in order to investigate the agronomic effectiveness of OMF. Despite u-XRF maps revealing that the mixture of PL and TSP as OMF resulted in P hot spots disseminated in a lowconcentration
background, whereas for the TSP treatment higher P concentration was uniformly distributed in
the granules, there was no difference in maize yield and fertilizer P recovery (%R) between P sources in both
soils. In the Oxisol, there was no difference between fertilizers in any of the soil P pools, but larger readily
phytoavailable P and smaller moderately labile P fractions were obtained with OMF. In the Entisol, the labile P
pool was larger with TSP. Nevertheless, acid and alkaline phosphatase activity and microbial biomass were
affected by P rate and P source. The results show that OMF is an effective substitute for conventional phosphate
fertilizers, since OMF promotes P recovery, plant P uptake and biomass yields compared to those obtained with
TSP. |
