Soil is the medium in which plants grow and thus it supports the lives on earth. The Study of Soil ( Pedology ) How soils are formed? Soils are formed due to the weathering of rocks. WHAT IS SOIL? Soil is the thin layer of loose mixture of small rock particles and rotting organic matter that covers much of the world’s land surface. Soil PowerPoint Presentation: ALLUVIAL SOIL PowerPoint Presentation: Formed by deposition of alluvium by rivers. Occupies 15 Lakh sqkm area in India. Contribute greatly in agricultural development. Two types: KHADAR & BHANGAR KHADAR : Newer alluvium. Sandy, pale brown composition. Found in lower areas. Flooded every year. ALLUVIAL SOIL ALLUVIAL SOIL: ALLUVIAL SOIL BANGAR : Older alluvium. Clayey & dark in colour . Coarse in nature. Contains Kankar (lime nodules), Pebbles and Gravels. Represents riverine alluvium of Himalayan rivers. The regions of alluvial soil are thickly populated and intensively cultivated ALLUVIAL SOIL: ALLUVIAL SOIL Characteristics : Transported soils. Coarser in upper section and finest in delta. Light to dark in colour . Rich in Potash & Humus. Poor in Phosphorous and Nitrogen. Highly fertile, good for all crops ( kharif & rabi ). Crops : Rice, Wheat, Sugarcane, Cotton, Jute . Areas : Punjab, Haryana, U.P, Bihar, W.B, Assam, Parts of Orissa, delta regions of S.India PowerPoint Presentation: Rice Wheat Maize Sugar cane Tobacco Cotton Jute Oilseeds Types of crops grown in alluvial soil PowerPoint Presentation: Major soil types PowerPoint Presentation: DILUVIUM PowerPoint Presentation: Diluvium is a term in geology for superficial deposits formed by flood-like operations of water. so contrasted with alluvium or alluvial deposits formed by slow and steady aqueous agencies. The term was formerly given to the boulder clay deposits, supposed to have been caused by the Noachian deluge. In the late 20th century Russian geologist Alexei Rudoy proposed the term "diluvium" for description of giant glacier-dammed lakes in intermontane basins of the Altai. The largest of these lakes, Chuya and Kuray, had volumes of water in hundreds of cubic kilometers. The term "diluvium" in the meaning of A. N. Rudoy has become accepted.  The process of diluvial morpholithogenesis can be found in modern textbooks. DILUVIUM SUMMARY: SUMMARY ALLUVIAL SOILS It covers about 40 percent of land area of the country. They are depositional soils, transported and deposited by rivers and streams. Through a narrow corridor in Rajasthan, they extend into the plains of Gujarath . These soils are formed by the deposition of fine sediments and silt by the rivers along their banks. In India, alluvial soils are mostly found in the Great Northern Plains, the coastal plains and river deltas Types (a)Young Khadar soils: these are newer alluvium of sandy, pale brown composition, (b) Old Bhangar soils: these consist of older alluvium SUMMARY: SUMMARY DILUVIAL SOILS The term in geology for superficial deposits formed by flood-like operations of water.
