Runoff
from the experimental plots was measured daily by
measuring the depth of water collected in the runoff
collection-tanks. To determine the soil and nutrient
losses, runoff samples were taken after thoroughly
churning the runoff with a rod, in one litre capacity
glass bottles. For every observation, two samples were
collected from each tank. These samples were stored
in a refrigerator at a temperature of 4C for 24–48 h in
order to allow the suspended sediments to settle down
at the bottom of the bottles. To determine the weight
of soil eroded, sediment yield from runoff sample in
one of the two bottles was dried in oven at 105C till
the constant weight was obtained and then weighed
using an electronic balance
