- Abstract
The research was aimed at studying a long-term influence of intensive tillage systems on water availability-related soil properties. This research had been carried out in Nawungan agricultural land, Imogiri in the clay soils dominantly by Lithic Ustorthent. Nawungan has long-term agricultural activities. It was used to be cultivated by rainfed paddy field, however, nowadays it has been cultivated by paddy-paddy-shallot pattern within a year. The seasonal crop rotation is to adjust water availability during dry season, and it must remain significant affect in soil properties. Water retention characteristics of soil was analysed in the study area. pF Curve was applied to study the availability of water, field capacity, and permanent wilting point in 9 soil samples. The soil sampling determination was based on water availability zones of the study area from the previous research. The analysis of water retention characteristics was also maintained by other soil properties analysis i.e. texture, infiltration, porosity, bulk density, and bulk volume. The results showed that the soil texture in the study area was predominantly clay, the bulk volume ranged from 0.87–1.21 gr/cm3, the specific gravity ranged from 1.78 to 2.10 gr/cm3, the infiltration rate ranged from 0.1–0.5 cm/hour, and the porosity ranges from 40–58%. Based on the relationship between soil water content and suction matrix (pF) at the study site, the field capacity value (pF 2.54) ranged from 42.56%–53.36%, the permanent wilting point value ranged from 33.29%–41, 55%, the available water content in the soil pores, which ranged from 5.89%–16.78%. Based on the position of the land to the lower slope, it was found that the average available water on the lower slope was 13.83%. This value was greater than if the available water on the middle and upper slopes that were 10.07% and 8.77%, respectively.
