O estudo teve como objetivos diagnosticar a realidade local; 2) elaborar as metas e estratégias para o desenvolvimento; e 3) apresentar as principais opções de investimento na agropecuária de Pinheiro para promover o seu desenvolvimento econômico auto-sustentado. As principais opções de investimento na agropecuária municipal envolvem exploração de culturas temporárias e perenes, suinocultura, avicultura e piscicultura. A organização dessas explorações será facilitada se foram adotados modelos de micropolos em áreas selecionadas do município. |

On tropical soils, liming and balanced nutrient supply are essential to ensure high
crop yield and quality. An adequate agronomic nutrient management should be a
balanced nutrition and fertilizers are the key factor on supplying nutrients. Urea is
the most commonly used fertilizer-N source, despite potential losses by NH3 volatilization.
Thus, new fertilizers technologies are needed to support the increasing demand
and avoid the low N use efficiency (NUE). The reduction of NH3-N volatilization
can be achieved by the use of natural aluminosilicates with nitrogenous fertilizer
materials. This review consolidates the current status on the subject and the experience
with the application of aluminosilicates as a slow release plant-nutrient fertilizer.
Volatilization losses of nitrogenous fertilizers on the soil surface could be reduced
with addition of natural aluminosilicates. Clay minerals (zeolites) are widely
used in many countries to reduce NH3 volatilization from amide N fertilizers, such as
urea, besides several organic forms of nitrogenous sources. The reduction in ammonia
losses by volatilization and the increased efficiency of N utilization and slow release
nature of urea-zeolite mixtures when urea is used together with aluminosilicates
was demonstrated in laboratory, greenhouse and field experiments with different
crops and environments. These results indicate that aluminosilicates minerals used
with urea mineral fertilizer can enhance the efficiency of this source by improving the
nitrogen use through the control of retention of ammonium ion, contributing to increasd
N uptake and crop yields. MenosOn tropical soils, liming and balanced nutrient supply are essential to ensure high
