Abstract

ABSTRACT: The adoption of rational conservation management of soil and water is fundamental to sustainability. The soil physical properties have important edaphic, since they involve directly in agricultural production. The aim of this study was to evaluate the behavior of some soil physical properties: the water depths and soil bulk density in two periods of the year in some soil in the municipality of Captain Wells, PA. Samples were collected at random depths (0-20, 20-40, 40-60 and 60-80) in two consecutive periods of the year, dry and rainy seasons, respectively. The experimental design was completely randomized (4 x 2 depths collection periods). The physical parameters analyzed in this study showed distinctions between periods and to the depth sampled.   KEY WORDS: density, moisture, profile soil.
