The floor is, literally and figuratively, the beginning of the large garden. Plants absorb much of what they need, in terms of oxygen, minerals, water and food from the earth. Open a textbook agricultural or horticultural, and you will see as counseling, "such as installation problems, check the soil and roots first." If a tree is sick, the first place to look, not the leaves, but around the trunk, and soil. (The main reason to see the trunk is to see whether the transport of food and water from the root to the tip of the tree is disturbed by a ring of trees.) For gardeners interested in maintaining an organic garden, rich soil, nutrient with a high content of organic matter is a must. Without good soil, farmers spend much time trying to fix problems on the ground, it would not be a problem if the ground was healthier.What is organic matter? To understand why organic matter is so important to the ground, we need to understand what it is. Chemically speaking, the term "organic" refers to the carbon molecules in them. The advantage of the organic matter has done to the smallest level of exchange of atoms. Humus is organic material is completely degraded into molecules of nutrients and change. Chopped leaves, compost, grass clippings and are examples of the organic matter that does not stop. Complete "digested", "compost" or "Broken Down" in a way that materials can be transported through the soil of the plant. It is accurate to the word "transportation" to use than "ate" or "consumed". The movement of molecules in the soil and plant cell wall is a chemical reaction, based on the cost (positive or negative) of the molecules and plant. Without really boring way of botany class is very interesting how roots work at the cellular level in the water, oxygen, nutrients and minerals that plants need.Organic matter is not only good for plant organic matter is essential for plants the nutrients they need, is organic matter that plants get their nutrients. Organic matter has a lot more, however. It provides food for microorganisms and macro-organisms living in symbiosis with plants. These organisms break larger pieces of organic matter into molecules small enough for plants to take inches of organic matter improves soil structure. The myth that soil health is completely uniform in consistency is just that: a myth. Water and oxygen fills the spaces between soil particles. If the soil is ground to a fine powder, is sensitive to erosion problems, as well as problems with drainage and oxygenation. Organic matter helps to regulate temperature. It also improves drainage and water, while almost impossible to replicate with a synthetically material.Ways for adding organic matter to soil SoilOrganic influence if differently, depending on the state of decomposition of compost. The fresh organic matter is degraded by soil organisms. During this process, nitrogen can be tied. If you are into organic material in soil-applied fertilizer, you need to add nitrogen. A good organic form of nitrogen, humic acid. As the organisms decompose organic matter, work based on the temperature of soil, compost decomposes faster in warm weather and slower in cold weather. Composting, hot and cold water (This is different.) Because of this, you can spread a layer of compost or shredded leaves in autumn, and decomposes slowly in the winter. In the spring you can again add soil and organic matter in degraded soils. The deeper in the soil organic matter, water holding capacity over and drought resistance of the soil will have. There is a case that should not add organic matter in soil. If you plant a new tree, do not add fertilizer in the hole, which is scientifically proven that the growth of roots outside the original planting hole to discourage. It is better to top-dress the planting of trees, use compost as fertilizer, rather than a soil amendment. Moreover, never in the composite, essentially defeat the purpose of improving soil structure. Organisms in the soil digest organic matter and spreading throughout the soil naturally.
