Scientific assessment on existing soil and land resources with respect to their spatial distribution,
characteristics, potentials, limitations were the pre-requisite for formulating sustainable land use strategies
to obtain higher land and water productivity. For quick collection of data and analysis, in this study,
various thematic maps were generated like slope, existing land use, available water capacity, organic
carbon, soil texture and bulk density were prepared and overlaid to develop integrated Composite Land
Development Unit (CLDU) map. A set of decision rules were applied on CLUDs to generate action plan
map, showing location specific recommendations on sustainable land use planning in the watershed.
The lowland rice areas which were presently under single cropping, could be converted to double/triple
cropping, particularly in fields where irrigation could be given. The rainfed lowlands with higher
available water capacity had a lot of residual soil moisture which could be utilized to grow low water
requiring crops like green gram, blackgram etc after rice. The irrigated lowland could be utilized by
incorporating one legume crop like green gram into cropping system after rice and one short duration
vegetable crops. Long duration rice of 150 days was to be avoided to convert mono-cropping to double
cropping. Since organic carbon content of the soil was low to medium, emphasis was also given for
organic carbon sequestration in the cultivable soil through conservation tillage. Morphometric analysis
of drainage network revealed that prominent drainage pattern of the watershed was dendritic with low
drainage density. Thus, the region had highly permeable subsoil material and had low relief.
