Soil properties in relation to plant growth
WebSoil is a physical system and can be described in terms of grain size, apparent density, porosity, moisture content, temperature, and friability. Plant growth is affected by the … WebA soil’s natural fertility depends largely on the parent materials from which the soil has developed and the original vegetation. Nutrients are held in the soil as electrically charged ions that can be positive ( cations) or negative ( anions ). As roots grow through the soil, they come into contact with cations and anions (held on the soil ...
