Question

soil fertility is considered as best soil resource- why?​

Answer 1

Explanation:

Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.[1] A fertile soil has the following properties:[2]

The ability to supply essential plant nutrients and water in adequate amounts and proportions for plant growth and reproduction; and

The absence of toxic substances which may inhibit plant growth.

The following properties contribute to soil fertility in most situations:

Sufficient soil depth for adequate root growth and water retention;

Good internal drainage, allowing sufficient aeration for optimal root growth (although some plants, such as rice, tolerate waterlogging);

Topsoil or horizon Oo is with sufficient soil organic matter for healthy soil structure and soil moisture retention;

Soil pH in the range 5.5 to 7.0 (suitable for most plants but some prefer or tolerate more acid or alkaline conditions);

Adequate concentrations of essential plant nutrients in plant-available forms;

Presence of a range of microorganisms that support plant growth.
