Pore Characteristics at Different Depths of Cultivated and a Fallow Land in Vertisol from Jeneponto South Sulawesi

Pore characteristics were describe the quantity, size, distribution, continuity, and stability of the soil pores and are strongly influenced by the amount of organic matter, the type and amount of clay, moisture, soil compaction, land management and land use. Common land uses in Jeneponto Regency are Cultivated and follow. This research aims to know pore characteristic at different depths on Cultivated field and a follow. Location, The soil sampling, is located respectively in Bajipamae, Punagaya Village, Bangkala Subdistrict, Jeneponto Regency. Soil samples were taken at depths of 0-15, 15-30, 30-45, and 45-60 cm at three points for each type of land used. Observation parameters include organic materials, texture, total pores, pore size distribution and pore stability. The results showed no real effect between land use type and depth of soil to organic matter and sand distribution, significantly affect the distribution of silt, and real interaction on the distribution of clay. Total soil porosity is significantly affected by the depth of soil. Land use and soil depth have a significant effect on pore diameter 28.8, 8.6-28.8, and 0.2-8.6 pore diameters and pore stability.
