what are the important consideration of soil
Answers
Answer:
Water is an important constituent of all kinds of soils. It is held in the soil by adhesive forces between water molecules and organic and inorganic particles, and by cohesive forces between adjacent water molecules. Water retention is largely related to the organic matter and clay contents, whereas water movement is influenced by bulk density, porosity, and permeability. Water holding in soil depends on physical properties of soil as well as its hydrogeochemical characteristics. The amount of water held plays a vital link between the precipitation and water content of the soil. This paper is an attempt to correlate the soil and its water holding capacity depending upon its characteristics so as to use these properties as tool for sustainable settlement development
Soil provides ecosystem services critical for life: soil acts as a water filter and a growing medium; provides habitat for billions of organisms, contributing to biodiversity; and supplies most of the antibiotics used to fight diseases.
