  3. Conservation of resources Land resources - land under variety of relief features like moutains plateaus, plains & Islands 1. Land utilization forest, uncultivated, fallow, net sown area & oter uncultivated land 2, Land use pattern-forest area lower than 33%,permanent posture has decreased, net sown area varied 3. Land degradation & conservation measures - Afforestation, stablization of sand dunes, management of waste land, control of mining

  4. LAND UTILISATION Land resouces in india are used for several purposes, such as wasteland-A part of the land that is not utilized for the moment is classified as wasteland Fallow land-Cultivated land that is not seeded for one or more growing seasons Forest Lands-Forests safeguard not only water but soil as well. They, thus, help in plunging the volume of floodwaters and their ferocity. Uncultivated Land-The uncultivated lands are subsidiary lands and are kept so to re-establish their richness. Pastures and other Grazing Lands-Credit must be confirmed on the farmers that with so modest land under pastures, they have the biggest number of cattle. They are nurtured mainly on husk, grain chaff, farm waste and few fodder crops.

  6. Soil Resource * Renewable natural resource, medium of plant growth & living system Classification of soil 1. Alluvial soil widely spread in northern plains, consist of sand, silt & clay.According to age is called Bangar & Khadar.very fertile & contain potash, phosphoric acid & lime 2. Black soil Regur soil, ideal for cotton, found in deccan trap, hold moisture, rich in calcium carbonate, magnesium, potash & lime 3. Red & yellow soil - develop on crystalline igneous rocks in low rainfall area, reddish due to diffusion of iron in crystalline rocks, yellow in hydrated form

  7. Major soil types in India Forest 8a mountain soil Medium black soi1 Terai soi Desert and arid soil Alluvial Soil Mixed redd and black soil Alluvial Soil Shallow black soil Red soil w. Deep black soil Deltaic alluvial soil Peaty and marshy soi1 Coastal alluvial soi1 Laterite and lateritic soil Saline and alkaline soil

  8. 4. Laterite soil brick,intense leaching due to rain, humus is low, useful for tea 5. Arid soil brown, sandy, saline, lack humus & moisture, kankar in low 6. Forest soil hilly& mountaneous area, loamy, & coffee & cashewnut plantation horizon restrict infilteration of water denundation, low humus Soil erosion & conservation Erosion occur in form of gullies, bad land, sheet erosion Soil conservation countour ploughing, terrace cultivation, strip cropping, shelter belts
