SOIL AND WATER CONSERVATION
Soil and Water Conservation Engineering (Deep Explanation) 1) Definition Soil and Water Conservation Engineering is the application of engineering principles and agronomic practices to protect soil and water resources from degradation, erosion, runoff loss, and moisture stress. Its main aim is: protect topsoil reduce runoff increase infiltration store rainwater improve groundwater recharge sustain agricultural productivity 2) Why it is important Topsoil contains: humus nutrients microbes good soil structure When erosion removes topsoil: fertility decreases crop yield reduces water holding capacity decreases land becomes unproductive In India, water erosion affects a major share of agricultural land, making SWCE crucial for sustainable farming. 3) Soil erosion (most important chapter) Soil erosion is the detachment, transport, and deposition of soil particles by agents like water and wind. Stages of erosion Detachment – soil pa...
