Organic C, and available N, P and K contents in
the runoff sediment were determined by using the wetdigestion method Alkaline KMnO4 method Bray’s P–I method and
NH4OAc method respectively At completion of the experiment, soil samples
were collected from 0–15 cm layer and analyzed to
study the impact of various conservation systems on
the soil fertility. Moisture content of the surface soil
(0–15 cm depth) at 0.5, 1.0 and 2 m distances from
the bund both on upstream and downstream sides and
at the centre of the plot (mid point between two
consecutive bunds) was measured by gravimetric
method.
