often in the literature or in the pages of Internet sites you can read about what to feed the plants must be used humus.What it is?The question often arises for beginners Horticultural case.In fact, usually called humus humus.It is formed by the decomposition of organic substances of plant origin.
animal manure, chicken manure, peat, sawdust, straw, grass as a result of microbial activity, they settled in, gradually becoming brown homogenous mass - humus.What is it, we hope you are more or less clear.Humus in the soil determines the degree of fertility.Direct dependence of yields of different crops on the percentage of humus in the soil in which they were grown, been demonstrated for a variety of research institutes.
Yes, even without any scientific research every gardener knows that plants, whether vegetables, berries, fruits or flowers for better growth needed humus.The content of humus in the soil needed to obtain a good result for them each species should be calculated separately.Similar calculations carried out and to find out the amount of humus contributed at one time, and to determine the frequency of such feedings.
Poor soils have little structural particles and easily dissolved in water.After watering or rain they formed crust, resulting in the roots of plants does not penetrate the air and water.The situation can be corrected humus.What is it, you know.Now look at how it affects the properties of the soil.Firstly, of course, it increases many times the amount of nutrients.Secondly, it becomes much more loose.After making a poor humus soil after watering crust on it it is no longer produced.By the plant roots with sufficient air flows and water.
Humus soil in home gardens, introduced artificially in the necessary quantities, makes the land much more fertile forest steppe and even.From uncultivated soils artificially the richest in the humus content of the soil is black earth.They are formed in the process of dying grass and flowers, which during the growing season accumulated a large plant mass.The last thing he found in podzolic and sandy soils.
Thus, organic matter is obtained from humus.What is it, we have already found.Now let's look more specifically, how it is formed.The organic matter contained in manure, is the food for soil microorganisms.During its decomposition in the first stage it is released carbon dioxide (CO2), nitrogen and phosphorus.Then, the last element of the organic is converted to ammonia.This process is possible thanks to the action of aerobic bacteria.Then, ammonia nitrogen goes into nitrate.
latter process occurs as a result of the two groups of microorganisms that act in this case as oxidants.When this ammonia initially converted to nitric acid, then transformed into ammonium salt nitrate.This phase can be considered final in the decomposition of manure.At this stage, it is converted into humus.
