After reading this article you will learn about the importance of soil aeration in physical and biological properties of soil. Importance of Soil Aeration in Physical Properties of Soil: i. Texture: Soil texture refers to the relative amounts of inorganic particles i.e. sand, silt and clay. Sand grains are large and coarse, clay particles are very fine and smooth, and [...]
This article throws light upon the three main factors affecting the composition of soil air. The factors are: 1. Oxygen 2. Carbon Dioxide 3. Water Vapour. Factor # 1. Oxygen: The amount of O2 in soil air is much less than that of the atmospheric air. Plant roots and different micro-organisms require O2 for their metabolism which they take from [...]
