Effect of Organic Materials Toward Production Plant.
The organic matter is the glue loose granules and a major source of nitrogen, phosphorus and sulfur. Organic materials tend to increase the amount of water that can be held in the soil and the amount of water available to the plants. Finally, the organic material is the energy source for micro bodies. Without organic matter biochemistry will cease all activities.
Such materials may include organic fertilizer, the process of change can occur naturally or artificially.
The organic matter is an essential ingredient in creating soil fertility, both in physics, chemistry and biology in terms of land. Organic material is the material aggregate soil stabilizer is excellent. and is a source of plant nutrients. Besides the organic material is the energy source of most soil organisms,
Organic materials can be obtained from plant residues like-root, stem, leaf fall, which is returned to the ground. 5% but its effect on soil properties is immense. Organic material functions are:
• As a granulator, which improve soil structure.
• Sources of nutrients N, P, S, micro elements and others.
• Increase the ability of soil to hold water.
• Increase the soil’s ability to hold nutrients (cation exchange capacity of the soil is high)
• Energy source for the microorganisms.
The organic matter is not absolutely required in plant nutrition, but for plant nutrition are efficient, role bole not negotiable. Contribution of organic matter on plant growth is pengruhnya the physical properties, chemical and biological soil. They have a role in providing chemical N, P and S for plant biological role in influencing the activity of organisms microflora and microfauna, and physical role in improving soil structure and others.
The organic matter plays several important roles in soil. Because organic material derived from plants that are left contains nutrients needed for plant growth. The organic matter affects soil structure and tend to keep raising the desired physical condition. The animals depend on soil organic matter for food and support the desired physical conditions by mixing the soil to form grooves. Since World War II, there was a large increase crop yields in some countries. The results of larger plants, especially where only grains are harvested, the rest – the rest is returned to tanamna more land and more here closing the plant during the growing season.
Immobilization is the reverse conversion. An example is the decision of ammonium or nitrate by plants or microorganisms and transformed into a protein. Furthermore, according to the back – behind the place.
If fresh plant residues added to the soil, nitrogen in the plant can be decomposed and mineralized by mikrrorganisme and immediately available to the plant, or it may not be mineralized nitrogen and not available to plants. There are two possibilities that could happen. If all the factors that affect this optimum decomposition (such oksien, temperature and humidity), the limiting factor in the process staying ratio of organic carbon to total nitrogen in the plant.
Immersion of fresh organic matter to the ratio C / N high, such as corn stalks (40) and straw (80), which is then immediately followed by the planting of additional nitrogen needs. Alternatively, when planting was delayed first order decomposition further opportunity to take a couple of days ago. Fresh organic ingredients with the ratio C / N is small, such as alfalfa and human waste, could be better and the soil can be directly planted.
Ratio C / N most of the land near 10. Ratio C / N humus itself is 10. Land – land, especially for breeding, the ratio C / N is high always require nitrogen fertilizers are quickly available nitrogen deficiency that does not happen.
