The Impact of Acid Mine Water on Soil Fertility in Cempaka, Banjarbaru District, South Kalimantan, Indonesia

Abstract

Banjarbaru has a topography with variety between 0 – 500m above sea level. the area with altitude of 7-25m above sea level have an indicates that the morphology in this area is very suitable for plant cultivation. Banjarbaru City has a slope of land with varies between 0-15%, but tends to be tilted. The slope usually related with sensitivity to soil erosion. hence soils in the Banjarbaru region are stable with relatively low risk of erosion, good land capability and fine soil textures. in this research the material used was a soil sample taken from several places around the South Kalimantan Province office complex. the samples of soil was taken in this research will be analyzed in a laboratory for getting the physical and chemical properties of the soil. Some chemical properties are determined such C, N, C / N, P2O5, K2O, P2O3, K2O, Ca, and KB. The results of laboratory analysis showed the content of some chemical elements contained in the soil consisted of C, N, C / N, P2O5, K2O, P2O3, K2O, Ca, and KB. C values ??range from 0.3 to 2.81, N ranges from 0.04 to 0.18, C / N ranges from 7 to 14., P2O5 ranges from 2 to 21, K2O values ??from 2 to 11, P2O3 ranges from 1 to 8, Ca ranges from 0.12 to 1.66, and family planning ranges from 7 to 54%. based on results showed that most of the land in the study area had a low KB, total P, total K and C-organic, so the area had a low fertility status. The saturation base is always connected as a clue about soil fertility.
