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. |

To evaluate the tillering dynamics of massai grass under rotational sheep stocking and fertilized with nitrogen (control - 0; 400; 800 and 1200 kg ha-1 year-1), this study was carried out, in a completely randomized design with repeated measures over time. The mob-grazing technique was applied to perform the grazing by employing groups of animals for rapid defoliation. The tiller appearance, survival and mortality rates, tiller biomass, and green/dead tillers ratio, have presented increase responses to nitrogen levels, with the three rates and the tiller biomass varying between evaluation periods. There was a quadratic response for the tiller flowering rate, population density of vegetative and reproductive tillers, reaching maximum values (0.051 tiller 100 tiller-1 day-1; 4,818 and 35 tillers m-2, respectively) under the nitrogen levels of 613.5; 993.5 and 623.9 kg ha-1 year-1, respectively. For the tiller flowering rate and population density of reproductive tillers, it was verified a fluctuation between periods. The nitrogen fertilization promotes positive changes in tillering dynamics of massai grass, allowing the use of up to 800 kg ha-1 year-1 for maintaining the pasture stability. The tillering demography of the forage had varied little between assessment periods. |
