Characterization of physical and water attributes of the Coastal Tablelands soils in Irrigation District of "Platô de Neópolis"

The lack of information about physical and water attributes in soils and their relationships with the irrigation management and crop productivity is one of the most important problem related to productivity of fruit crops at the Irrigation District of "Platô de Neopolis". This fact is of great relevance considering the clear evidence of the occurrence of expressive soil variations, regarding the water holding capacity and plant water supplies in such soils and the consequences in irrigation effectiveness and crop costs. Despite the proximity of the areas and their location in the same landscape, their physical and water proprieties are affected in different intensities by the hardened soil layers, depending on the position in soil profile and degree of soil hardening, thus it is necessary to adopt specific and differentiated pratices of soil and irrigation management for the development of fruit crop in the "Platô de Neópolis".
