Soil-land form relationship was studied for Ayyammanahalli village by the interpretation of satellite and Google earth imagery. Sampling areas in transect were marked along the slopes based on the tonal variation. The selected transect areas were marked for profile study, five representative pedons were exposed on five different physiography, like Upland summit, Upland lower sector, Upland upper sector, shoulder of upland and lowland. The study area represents semi arid tropical climate. It has vast areas of upland and considerable area of lowland. Majority of the upland is under field crops. Upland has very gentle to gentle slope.Keywords

A laboratory experiment was conducted to study the persistence and degradation of propineb in soils from Malur and Hassan (sandy clay loamy) at 25 and 50 μg g-1 with field capacity and half-field capacity moisture regimes. The degradation pattern followed the first order kinetics. Degradation of propineb was faster under field capacity than half-field capacity moisture regimes at both rates in both the soils. Higher degradation was noticed in Malur soil than Hassan soil at both the rates of application and moisture regimes. The half-life values ranged from 6.5 to 7.1 days for Malur soil and 6.9 to 7.1 days for Hassan soil when applied at 25 and 50 μg g-1 of propineb under field capacity. Under half-field capacity the half-life ranged from 7.1 to 7.9 days for Malur soil and 9.1 and 9.8 days when applied at 25 and 50 μg g-1 of propineb, respectively.Keywords
