The use of arable land for crops consecutive time. The soil will gradually Deteriorate indefinitely If land use, abuse, and lack of maintenance. Or conservation, then it makes the soil more quickly deteriorated. The deterioration of the soil, there are several important characteristics. Such as loss of soil nutrients that are beneficial to crops due to soil being opened. Causing erosion. Combination of cultural improper use of tools such as heavy tillage with high moisture in the soil physical properties of soil degradation, soil compaction. Blocking root growth and drainage and air. The fertilizer plant using some scientific consecutive time, making the soil more acidic. Therefore, it is necessary to have a soil conservation and management. To prevent deterioration of soil conservation or reduce the degradation of the soil. The soil can be sustainable. According to the text above to separate the issues of soil conservation is as follows
: 1) to reduce corrosion is accelerated down as much as possible. Until losing ground to the rate of soil similar. And trying to balance these
two) to maintain nutrients in soil fertility by preventing the loss of unnecessary or replace those lost by way of one or
three) to maintain the level of organic matter by. control the rate of decay Or by adding the fossil to draw
4) to maintain the physical properties of soil associated with the growth of plants such as the incoherent storage absorbency and air as well as to try and optimized for more plants. more
5) to the water contained in the soil for the benefit of
the other. The conservation of soil caused by various issues. Abovementioned Are as follows
: 1) to prepare the soil by soil makes it resistant to corrosion and sediment. Impermeable and can be improved. Try to keep the amount of water, air and nutrients for optimum growth of the plant at all times
2) the cover to prevent the impact of rain and wind as a ground cover with crops or residues of plant protection. the soil from the impact of raindrops. Reduce the speed of the wind, soil and other soil additives
3) the speed of water runoff, and the wind dropped. This is to help reduce soil erosion and sediment particles. Like adding the ability to allow water penetration into the soil easily, or to create obstacles to the flow of water and the wind blowing
4) making the drainage of water runoff. And prevent the loss of soil by the stairs. And covering soil with grass or small plants
to conserve soil management, some are
1) the planting of ground cover. This is usually the plants with thick leaves and root system for a tight and secure the ground. Such as legumes or grasses, legumes
2) crop rotation. Is different crops on the same land to rotate. In general, choose plants with root systems differ. Some much needed nutrients differently. And the chemical composition is not the same as, for example, rice, corn, soybean and Crotalaria rotate
3) Mulching with any such materials may be waste of plants to help prevent corrosion. Reduce the impact of rain and strong wind. Keeping moisture out of the soil for a longer time. It improves durability in the grip of a lump of clay to make the absorption of water into the soil better
4) growing along the level. The action in the field can not be done on the floors. Cascaded down the line across the slope to reduce soil erosion and sediment
5) to spend time in a bar. The different crops on the same land, the slope of the diagonal or horizontal stripes are. There can often be accomplished with a few
6) making up the stairs. Is to create a ridge across the slope of the area and planted terraces. As well as the ladder
