Classification of Crops

Science > Biology > Management of Crop Production > Classification of Crops All living organisms need food for survival, health, growth, and development. Food provides nutrients like carbohydrates, fats, protein, vitamins, and minerals. Different crops require different climatic conditions, temperature, and photoperiods for their growth and completion of their life cycle. The growth of plants […]

Green Revolution

Science > Biology > Improvement in Crop variety > The Green Revolution At the time of independence, India was partitioned into two countries. The most agriculturally productive land came under Pakistan with a small population while India has to support a larger population compared to Pakistan. Similarly, at the time of its independence, India was […]

Soil Erosion

Science > Biology > Soil Management > Soil Erosion The removal of the top fertile layer of the soil from the soil is called soil erosion. It is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing and transportation of topsoil of the field by the natural physical […]

Air Pollution

The word pollution comes from the Latin ‘polluere’ that simply means contamination. Pollution is any undesirable change in physical, chemical or biological characteristics of air, land, water or soil. Agents that bring about such an undesirable change are called pollutants. Pollution affects the biodiversity of the ecosystem and poses a threat to the sustainability of […]

Soil Profile

Science > Biology > Soil Management > Soil Profile A vertical section through different layers of the soil is called the soil profile. Each layer differs in feel (texture), colour, depth, and chemical composition. These layers are called horizons. Soil texture depends on the size of individual soil particles and is determined by the relative proportions of particle sizes […]
