What is the life of the soil?

in a very kilogram of fertile soil is 100 billion and 3 trillion organisms, most of them. The soil is a thin layer of permanently decaying organic matter that covers most of the earth. In the soil, organisms divide dead organisms into their basic elements prepared for reabsorbing plants. Without the life of the soil, the new generation of plants could not recycle the biomass of the latest generation and life on Earth as a whole would stop. The life of the soil is generally classified by its size. At the top of the food chain are megafauna, larger than 20 mm in size: moths, rabbits and rodents. Below them are macrofauna, ranging from 2-20 mm: Woodlice, earthworms, centipedes, snails, beetles, slugs, ants and harvesters. Then there are mesofauna, which moves in size of 100 microns 2 mm: tardigrady, mites and springs. The smallest are microfauna and microflora with a size range between 1-100 micrometers: yeast, bacteria, fungi, professionarybitozoa, Roundorms and Rotifers. Even under which there are many trillion viruses, although exIt disagrees whether these mobile genetic elements are really life.

Over many millions of years, bacterial soil has created a deep symbiotic relationship with plants known as legumes (beans, peanuts, alfalfa), grew in their roots and "strengthened" atmospheric nitrogen, gas, into solid organic compounds such as ammonia. Nitrogen filling bacteria also live independently in large quantities. This nitrogen fixation is essential for a lifetime that only bacteria could function until the development of the Haber process. Nitrification bacteria specialize in the conversion of ammonia, the first product, nitrates that can actually use plants for nutrition.

Depending on the severity of the environment conditions, the life of the soil may be more or less abundant. When the conditions are rough, for example in Antarctica, large organisms are the first to go. In what little exists AntarcticSoil, there is no megafauna and macros, but the mesofauna is present in the form of sources.

If you want to see how the life of the soil appears in the garden, throw away the ripe fruit there and wait a few days. The effects should soon be noticeable.
