| soil science objective questions: Descriptive & Objective : Soil Science P. Gurumurthy, 2022-07-08 Soil is the most fundamental reswource to fulfill basic requirements of food, fiber and shelter of human race. Soil forms basis for all terrestrial life. Soil provides a wide range of ecosystem services that make humankind to survive and progress. Soils are complex mixtures of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once-living things. It forms at the surface of land and is the “skin of the earth”. Soil is capable of supporting plant life and is vital to life on earth. The present publication ‘Descriptive and Objective Soil Science' aimed to provide chapter wise brief information on different concepts of soil science viz., Soil genesis, Soil physics, Soil chemistry, Soil mineralogy, Soil heath, Soil fertility, Manures and Fertilisers, Soil degradation, Problematic soils, Soils of India, Irrigation water quality, so on along with objective questions at the end of the each chapter. This book is useful for B.Sc (Agriculture), B.Sc. (Horticulture), B.Sc. (Environment Science), JRF, SRF, ARS, SAUs and other Competitive Examinations) |

| soil science objective questions: Soil Formation Nico van Breemen, Peter Buurman, 2007-08-20 Soils form a unique and irreplaceable essential resource for all terrestrial organisms, including man. Soils form not only the very thin outer skin of the earth's crust that is exploited by plant roots for anchorage and supply of water and nutrients. Soils are complex natural bodies formed under the influence of plants, microorganisms and soil animals, water and air from their parent material, i.e. solid rock or unconsolidated sediments. Physically, chemically and mineralogically they usually differ strongly from the parent material, and normally are far more suitable as a rooting medium for plants. In addition to serving as a substrate for plant growth, including crops and pasture, soils play a dominant role in the biogeochemical cycling of water, carbon, nitrogen and other elements, influencing the chemical composition and turnover rates of substances in the atmosphere and the hydrosphere. Soils take decades to millennia to form. We tread on them and do not usually see their interior, so we tend to take them for granted. But improper and abusive agricultural management, careless land- clearing and reclamation, man-induced erosion, salinisation and acidification, desertification, air- and water pollution, and withdrawal of land for housing, industry and transportation now destroy soils more rapidly than they can be formed. |
