Abstract

Soil water characteristics is the main information in the irrigation planning and management especially in the new rice field opening program. Monitoring soil water characteristics is needed in scheduling irrigation and determining the amount of water for irrigation. The aim of this reseacrh is to analyze the influence of water management on soil water dynamics in newly opened rice field. This study used an experimental method with two treatment were SRI and conventional. The results of soil analysis showed that the soil in the study area had a clay texture, the wilting point and field capacity in 10 cm soil depth are 34,5% and 44,7%, respectively. In addition, the C-organic content value of 2.68 - 2.91% and low soil fertility status. The average of soil water avaiability in SRI field at 10 cm was lower than soil water availability in conventional field, where 2,30 mm and 4,86 mm, respectively.
