Water storage in Dystrophic Dusky Red Latosol under pasture condition and annual crops
Water storage was determined in a Dusky Red Latosol Dystrophic at Lavras, MG, Brazil, under natural pasture and annual crops during one year by sampling each fourteen days. Moisture determination was conducted in three relief positions upper, middle and lower with three replications in the layers 0-15, 15-30, 30-45, 45-60, 60-75, 75-90 and 90-105 cm. The water storage was obtained integrating water content for each soil layer considered. The water storage data showed differences among canopy In relation to thickness, sampling turn and relief position. The water storage and the fluctuations were greater to the water tank. The natural pasture soil storaged more water than annual crop soil, as well as lost too. The moisture regime to the Dystrophic Dusky Red Latosol was identified as udic moisture regime in both canopies.
