Avaliação da umidade natural do solo em sucessivas barragens subterrâneas no Riacho Angico, pertencente à Região do Médio Paraíba.

Abstract

The terracing with tire stripes, implemented on a depredated area, showed, visually, a good efficiency on soil accumulation. Soil samples were collected on 57 points at depth intervals of 0-30, 30-60 and 60-90cm, along a river that has 6 sequenced subterranean reservoirs, as well as in testimonies areas (upward and downward from the BAPUCASA structure) with the objective of evaluate the soil physical-hydrical and physical-chemic attributes. The results showed the presence of mainly sandy soils. As it was expected the lowest soil water availability was found during the month of December (dry period). On April 2005 (rainy period) the areas upward the BAPUCOSA barramundis had medium soil moisture contents however upward these, the soil water availability was much higher showing, thus, that the BAPUCOSA constructions increased the soil water availability for plants.
