Indicadores da qualidade do solo em um sistema de roça de corte e queima em regeneração no Projeto de Assentamento Araras

Abstract

The soil quality is an ample conception that makes reference to the physical, chemical and biological equilibrium of the soil. Being related to the aptness grade of an speciflc use too, which depends on the agricultural practices adopted and the natural composition of the soil. Objectiving give continuity to the work, who characterized and evaluated the organisms presence at the soil after the fire use, the current work pretendered study on April 2008 the chemical, physical and biological indicators of the same area in regeneration process. Ten simple samples of soil were aleatoric collected. For the physical characterization, the color, texture, structure and infiltration tax was evaluate. For the biological datum the diversity table Margaref, Simpson and Shannon was utilized. The chemical datum was obtain by chemical analysis of the soil. It follows that happened & increase on the phosphorus concentration aher burning, due to mineralization propitiated by burning. The soil quality indicative organisms kept aher planted area treatment, wherein after the tract of newly cleared land implant. The vegetable cover presence conferred for this soil & major organic material accumulation verified by a grumose structure.
