TRANFORMATION OF SULPHUR IN SOILS OF NORTH KARNATAKA AS INFLUENCED BY SOURCES AND LEVELS OF SULPHUR

Abstract

A Laboratory incubation experiment was conducted in Vertisol and an Inceptisol of North Karnataka to know the effect of different sources and levels of sulphur and time of incubation on transformation of available S in soils. Among the different sources of sulphur, ammonium sulphate recorded the highest release of 5 due to its more soluble. nature compared to other sources. The available S content was more in inceptisol. There was a rapid release of S during the first fifteen days of incubation followed by a slower linear release.
