Efeito do preparo mecanizado do solo sobre alguns parâmetros físico-hídricos do solo no nordeste paraense.

Abstract

This work was conducted in a farmer's area of the district of Tracuateua, in soil classified as LA, medium textured, to evaluate the effects of mechanized soil preparation in some physical and hydric soil parameters of the soil. Two areas were selected, as follows: a) Fallow, with three years of age mechanically prepared, where citrus were planted intercroped with cowpea; b) Three years fallow as a control plot.. The results showed that the use of machinery caused soil compaction when compared to the control plot, which had better physical conditions for plant growth. Low water availability that may eventualy occurs in a short period during the rainy season, locally called "veranicos", can decrease yield of crops, indicating that more attention should be given to the utilization of management practices to keep adequate soil moisture for longer period of time.
