evaluation of land resources of Mawryngkneng block was carried out using IRS-P6
LISS III and LISS-IV data. Five major physiographic units namely structural
hills, denudational hills, plateau and intermontane valley were identified.
Visual interpretation of satellite data indicated that 32.2% of the total geographical
area (TGA) is under dense forest followed by wastelands (28.8%), open forest
(16.1%), cultivated area (13.6%), built up area (8.2%) and water body (0.9%).
Ten soil series were tentatively identified and the soils belonged to 2 orders
(Ultisols and Alfisols), 3 sub orders (Udult, Udalf and Humult), 6 great
groups, 8 sub groups. The soils are moderately acidic, deep to very deep and
texture varies from sandy clay loam to clay. The soils are very rich in organic
carbon. The availability of nitrogen is medium to high and phosphorus
availability is low to medium whereas potassium availability is low in the
entire study area. The soils were grouped into land capability class II &
III and the soils were moderately to marginally suitable for orange and
marginally suitable for pine apple. An action plan with suggested land use and
interventions has been prepared by using all land resource information
generated under the study. The action plan includes areas for afforestation,
intensive cultivation in the existing cropped areas with soil conservation
measures like mulching, zero tillage etc. and orange and pine apple plantation
in open scrub lands which are cultivable wastelands. This might help the
farmers and the planner in better management of land resources for sustained
