Abstract
The application of soil amendment is one of the major management practices in
farming operations. Nowadays, the importance of manure application as a soil
amendment is increasing due to the increased concern for the ecology and environment
its abundance in availability and low cost. The manures are rich in organic matter content
and other nutrients. It changes the physical properties of the soil. But the excess
application of organic manure may lead to detrimental results due to the surface seal
formation. Hence, the present study attempts to assess the effect of seal formation due to
cattle manure application on infiltration and runoff. In the coarse textured soils, like
sandy loam soil the infiltration rate will be reduced and runoff will be increased. But in
the fine textured soils, like clay loam soil, the infiltration rate will be increased and runoff
will be reduced. The contents of the nutrients like nitrogen, organic matter and total
solids in the runoff water and the physical properties like bulk density will increase with
the increase in manure application and rainfall intensity. Hence it was concluded that,
while applying manure on the field, the rate of application of the manure can be
determined only after determining the soil texture and rainfall intensity. Otherwise, the
manure application will be results in pollution of nearby water bodies.
