Various methods for water or soil humidity conservation include the use of chemicals (synthetic matter) and plastic or asphalt layer at certain depth under soil profile to hold irrigation or rain water entering into the soil to prevent rapid disappearance from root zone. The present study observed the role of fine texture soil (clay fraction) in increasing water capacity, and releasing power of water for the need of plantation in margwial soil with sand easily pressed structure, and sensitive to water and wind erosion. The study was carried out in Glagah Coast, Kulon Progo, Yogyakarta. The results conclude that the addition of 10 cm of clay layer at the depth of 20-30 cm may optimally increase the humidity of sandy soil.
