Yes,the soil microbes contribute to the soil nutrients supply soil N,P through nitrogen fixation, mycorrhizae, decomposition of plant and animals remains which supply N,P,K ,Ca,Mg and organic matter.The soil microbes decompose applied agrochemicals and fertilizer to the soil which help to reduce soil and water pollution as well as toxicity of the soils This significant role has contributed to maintain good sóil health and clean environment.Also, the roles of microbes in detoxifying the effects of spilled crude oil and waste in soils and water can not be overemphasized because they maintain clean environment in oil producing areas as well as supporting aquaculture development.Finally,the roles of microbes in decomposition of agricultural wastes through composting methods to produce organic fertilizers which are important in safe eating of organic foods as well as maintaining clean environment
Soil microorganisms are responsible for most of the nutrient release from organic matter. When microorganisms decompose organic matter, they use the carbon and nutrients in the organic matter for their own growth. They release excess nutrients into the soil where they can be taken up by plants. Beneficial soil microbes perform fundamental functions such as nutrient cycling, breaking down crop residues, and stimulating plant growth. Microorganisms regulate soil properties and fertility through different pathways: (1) microbes can activate soil nutrients and promote their availability; (2) nitrogen-fixing bacteria improve soil fertility by transforming the nitrogen elements; (3) the extracellular secretions of microbes can enhance the stability of soil properties. Microorganisms help in cleaning up the environment. They decompose dead and decaying matter from plants and animals; convert them into simpler substances which are later used up by other plants and animals. Thus, they are used to breakdown harmful substances. Microbes thrive under no-till conditions and winter cover crops. Cover crops and manure can be used to feed soil microbes and recycle soil nutrients. As soil microbes decompose organic residues, they slowly release nutrients back into the soil for the winter cover crops or for the preceding crop. They increase soil fertility by incorporating air, minerals and nitrogenous compounds. They contribute in increasing plant growth by providing essential elements, minerals that plants cannot utilize by their Owen. Microorganisms decompose organic matter to simpler form that can be easily uptake by plants. Microorganisms play a crucial role in nutrient cycling in soil. The composition and activity of microbiota impact the soil quality status, health, and nutrient enrichment. Microbes are essential for nutrient mobility and absorption. Through their varied functions, they stimulate plant growth and reduce diseases.
