Soil fertility is the ability of a soil to sustain plant growth by providing essential plant nutrients and favorable chemical, physical, and biological characteristics as a habitat for plant growth. Plant nutrients include the macronutrients nitrogen, phosphorus and potassium, sulfur, calcium and magnesium.

The ability to perform this function is referred to as soil fertility. The clay and organic matter (om) content of a soil directly influence its fertility. Greater clay and om content will generally lead to greater soil fertility. The soil in figure 2 has a dark brown to black color, indicating abundant om accumulation, and a highly fertile soil.

Because the fertility of the soil decreases by the process of leaching and weathering in course of time. Besides this, cultivation of crops without manuring decreases the fertility of soil. Micro-organism and soil fertility: various types of organism live in the soil.
Soil has always been considered as a living system due to its biological components: fungi, bacteria and plant roots. Under several ongoing research projects, we started researching how we can use ‘cotton strip assay’ to compare different cover crop mixes to optimize field soil activity and build up better soil health.

Soil fertility problems may also occur when the soil ph is outside the ideal range for plant growth.
The thing about fertility in soil is that it can be fleeting. There is so much below the soil going on, it is truly amazing. Bacteria, algae, fungus, chemical reactions, water penetration and flow, and roots are all working 24/7 to live off that soil.

Accordingly, “fertility” can be considered an inherent property of a given soil. However, the plant itself is able to modify soil fertility in two different ways. One is based on the “rhizosphere effect” exerted by the plant, which can alter the fluxes of energy and the supply of substrates for soil microorganisms.
