The fragility of the semiarid regions has been neglected, seeing that these areas still are adopted as agricultural conventional models, such as cutting and burning agriculture, resulting in the compromising of soil quality. In this context, the Agroforestry Systems (AFS) have been pointed as alternative of the soil management for the semiarid, mainly for the capacity to increment organic matter on soil, that associated to the addiction of organic waste can reduce the degradation process. The objective of the study was quantifying the effects of adoption of a new organic waste management over chemical attributes of Agroforestry System soil alleys, handled with or without burn. Utilizing subdivide parcels, was verified the effect of fire and of organic waste handled singly (gliricidia) or combined (gliricidia and carnauba bagana, gliricidia and bio compound, and the combination of the three wastes. Was observed that the gliricidia is efficient on contribute of soil nutrient, mainly considering it’s chemical composition. Was observed the efficiency in the consortium use of organic waste as for the increment of nutrients for the soil, going on of synchronization between nutrients availability and demand for these by the system. Next, AFSs handled with the consortium of diversified organic waste is an efficient management alternative effective on nutrient increment and degradation reduction of the region soils, in which was observed elevation in contents of macronutrients, raise of pH values, of CTC, as of micronutrients.
