Indicadores de uso do solo para a região do canal do sertão no semiárido Alagoano

Abstract

He present work aims to increase knowledge about the dynamics of soil physical processes in the semi - arid region of the state of Alagoas, aiming to optimize information about the study of soil water to the region 's farmers. The study began with the understanding of soil physical attributes monitoring, through the determination of the soil moisture characteristic curves, aiming the contribution to the rational use of water in the region of the Alagoas sertão, as well as determination of the water balance of the main crops in the regions under study. For that, the analysis of the research was done in laboratory research, analyzing different types of soils, in different depths. The soil was collected in the semi-arid region of the state of Alagoas, located between the municipalities of Pariconha, Delmiro Gouveia and Inhapi, with the participation of the members of the team. In each soil class, the samples were collected in five soil profiles, with samples collected at three depths. The laboratory characteristics will be carried out at the Center of Agricultural Sciences of the Federal University of Alagoas (CECA / UFAL), where the soil field capacity, soil density, soil physical and water characteristics were determined, such as particle density, stability of aggregates in water, and also the soil moisture characteristic curve, defining a water balance (through established methodologies) for the main crops grown in the study region. The soil Will be collected at the specified locations, training to perform the soil evaluation processes (identification of samples, discharging, drying, weighing, course of equipment operation and maintenance), a literature review will be carried out on the subject optimize data and generate future comparisons with existing materials.
