Soil of Telangana INTRODUCTION Soil is an important matter for cultivation of crops. Soil supplies all the important factors for the Growth of the crop Plants. The yielding potential is largely dependent on the soil in which the crops are grown. The type and properties of soil directly affect the crop growth and yield, hence … Read more
Minerals Minerals are defined as solid, inorganic, naturally occurring substances with a definite chemical formula and general structure. Almost all chemical Elements in the Earth’s crust are associated with at least one mineral. They vary in color, hardness, density, crystal form, crystal size, transparency, composition, location, and abundance. Some minerals are radioactive (uranophane), while others … Read more
Eleven groups of Soil orders are found in Karnataka Entisols, Inceptisols, Mollisols, Spodosols, Alfisols, Ultisols, Oxisols, Aridisols, Vertisols, Andisols and Histosols. Depending on the agricultural capability of the soil, the Soil Types are divided into six types viz., Red, lateritic(lateritic soil is found in bidar and kolar district), black, alluvio-colluvial, forest and coastal soils. The common Types of Soil groups found in Karnataka are Red soils: Red … Read more
Metal In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic Bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons. The metals are one of the three groups of Elements as distinguished by their ionization and bonding properties, along … Read more
Acid An acid is a substance which forms H+ ions as the only positive ion in aqueous solution. Examples:- Hydrochloric acid dissolved in water forms H+ and Cl– ions HCl —> H+ + Cl– Sulphuric acid dissolved in water forms H+ and SO42- ions H2SO4 —>2H+ + SO42- Nitric acid forms H+ and NO3– ions when dissolved in water HNO3 —> H+ + NO3– … Read more
Soil is defined as upper layer of the earth composed of loose surface material. It is a mixture of many substances including endless variety of Minerals, remnants of Plants and animals, water and air. It is the end product of continuing interaction between the parent material, local Climate, plant and animal organisms and elevation … Read more
Saline soils Saline soils are a type of SoilSoil that has a high concentration of salts. These salts can come from a variety of sources, including natural deposits, irrigation water, and industrial runoff. Saline soils can be a major problem for agriculture, as they can reduce crop yields and make it difficult for plants to … Read more
Types of SoilSoil Soil is a complex mixture of minerals, organic matter, water, air, and living organisms. It is essential for life on Earth, as it provides a medium for plant growth and supports a wide range of other organisms. There are many different types of soil, each with its own unique characteristics. The type … Read more

What is a Fuel Cell? A fuel cell is an electrochemical device that converts chemical energy from a fuel into electrical energy and heat. Fuel cells are similar to batteries in that they both convert chemical energy into electrical energy, but fuel cells do not run down and need to be recharged. Instead, they can … Read more
