Abstract

This research was conducted in the tidal land P17-5S Mulia Sari Village, Tanjung Lago District, South Sumatra, in July 2018 to September 2018. The method used was purposive sampling, where every 1 ha was taken 1 soil sample at a depth of 0-20 cm and 20 -40. The results showed that different land uses affect changes in soil physical properties. In the land of black soil rubber plants at a depth of 0-20 cm is influenced by the content of organic matter. Oil palm and corn plantations have a very dark brown color at a depth of 0-20 cm influenced by the iron content contained in the soil and low plant water. At a depth of 20 - 40 cm the color of the soil in three land uses tends to be gray, the gray color of the general soil is caused by the organic matter content of high plant residues and poor drainage Soil texture in rubber plantations is dominated by fractions clay 51.6 % and 64.4 % sand with sandy clay texture class, oil palm plantations dominated by sand fraction 78.4 % and clay 51.6 % with sandy clay texture class, oil palm land dominated by sand fraction 72.4 % and 49.6 % clay with sandy clay texture class. The value of the average weight of the contents of the rubber plantations 0.71 g/cm3 and 1.06 g/cm3, oil palm plantations 0.74 g/cm3 and 1.02 g/cm3, corn plant land 0.89 g/cm3 and 0.97 g/cm3. Rubber plantations have no effect on bulk density, while corn plantations have an effect on bulk density because corn plants with dense vegetation will tend to absorb water more than land that has sparse vegetation such as rubber and palm oil. Based on the average value of the weight contents of the soil contents in the land of rubber, palm and corn crops, the value of the weight of the soil content has increased along with the increase in soil depth from 0-20 cm deep to 20-40 cm. This is due to the increasing depth of the soil, the organic content will be lower, making the soil compaction process easier, causing the weight of the soil to be higher. The average total pore space value is 73.15 % and 59.84 % of rubber plantations, 72.01 % 61.53 % of oil palm plantations, 66.10 % and 63.31 % of maize plantations. The highest soil hardness in rubber plantations was 3.4 kg/cm2, while the lowest was in corn plantations which was 1.9 kg/cm2
