Author(s): Ananthakumar MA, Manohara BA, Kadalli GG and Prakash SS
Abstract: Soil acidity is one of the limiting factor affecting growth and development of various crops. A field experiment was carried out during Kharif 2016 at Bio Fuel Park, Madenur, Hassan district in acid soil to ameliorate both surface and subsurface soil acidity using different calcium sources viz., lime, dolomite and gypsum and to study their effect on availability of nutrients. The treatment combination includes application of lime and dolomite @ 50 percent lime requirement with and without elemental sulphur @ 100 kg ha-1 and was compared with gypsum levels and control. The results revealed that the application of lime and dolomite increased the soil pH, organic carbon content, available nitrogen content and dehydrogenase activity in both surface and subsurface soil. Exchangeable calcium and available sulphur contents were increased in gypsum treated plots compared to control. Low Exch. acidity and Exch. Al and high Exch. Mg content were observed with dolomite and elemental sulphur application.
