The below mentioned article provides biology notes on Water Absorption from Soil. Soil is the upper weathered, humus, mineral water and air containing layer of the earth’s crust which supports plant life. Water is an important constituent of soil because all land plants depend upon it for their requirement of water. Deep in the soil and above the imperÂmeable stratum, [...]
Physicochemical properties of soil include soil texture, water, air, inorganic chemicals, and organic matter. The biological factors of soil are soil flora and fauna. Mechanical composition (texture) of soil is determined on the basis of size of soil particles i.e. sand, silt and clay particles (Table 30.1). However, the ratio of soil particles governs the porosity (pore size of soil), [...]
