Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. One gram of fertile soil can hold up to one billion bacteria. The study of soil is important in many respects. Plants and these beneficial microorganisms are both involved in nutrient recycling. Soil organisms, which range in size from microscopic cells that digest decaying organic material to small mammals that live primarily on other soil organisms, play an important role in maintaining fertility, structure, drainage, and aeration of soil. Free-living soil bacteria beneficial to plant growth, usually referred to as plant growth promoting rhizobacteria (PGPR), are capable of promoting plant growth by colonizing the plant root. Microorganisms known as gut flora help us digest food and regulate the production of vitamins and nutrients essential to keeping our bodies strong and healthy. Corrections? The change of organic nitrogenous compounds into ammonia is called ammonification. Plant growth results from the interaction between roots and their environment, which is the soil or planting medium that provides structural support as well as water and nutrients to the plant. In this sense, there are many beneficial microorganisms that can be used to improve the quality and yield of crops. Nitrogen fixation is one of these processes. There are several types of plant-microbe interactions, including competition, commensalism, mutualism, and parasitism. Microbes in Agriculture and health with special reference to bacteria.
