The structure of the soil (Soil Structure)
.The properties of the soil. Of the soil particles in lumps or soil with various sizes together the loose, natural soil condition makes clear. Not thick, Sandy and clay. If there is a reasonable structureAnd the dense, the original property of soil that such as clay properties เดิมคือ, tough and thick. If we put down for a long time, organic fertilizer The great structure will occur, which results in the soil that has clear.Because the soil will rise. Since particles clay is captured the island a soil nubble. Together loosely, as well as sandy soil, the original property clear, too. When manure is put into the soil for a long time.The sand particle that loose. To catch the island into soil of small, dense, reduce the transparency into the WHC. Better tillage is still simple and convenient intact. So the soil structure change, namely.Or breaking. The soil texture, we can be difficult, especially in the field condition the soil mix. Plant in pots. We can change the type of the earth
.Structural characteristics of soil has good
. State of soil grain size island a little rogue struck some smaller, or it may be โตกว่ made a little together loosely for a layer of top soil depth. About 15 to 20 cm.Surface soil (soil) of these is durable enough impact of rainwater or tillage, but if tillage planting for a long time. Assembly with no additional organic fertilizer into the soil. This structure will be dismissed.The clay will return to dense and hard when dry, and the sandy soil can absorb water is less. The soil is clear and quick drying too
.
.Soil that contains a great structure. Is mainly caused by soil organic matter interlayer clay particles, sediment and sand together a small amount, so soil organic fertilizer into the soil.When organic matter in the soil over. The structure of soil to breaking with the use of chemical fertilizers. Will have no effect in helping the cause great structure. So the soil is sand, or clay, which originally had a good structure.Even if the plants are growing well is a high turnout in the first stage, but for a long time. The organic matter in soil will gradually disappear. Great structure of soil to breaking, that there are those who say that if the use of chemical fertilizer and soil lose it.When the good structure of soil deterioration down, that is, the clay is dense, the sandy soil is low too. It even Pro Sui chemical fertilizer. The plants will not grow as well as usual. In this condition the roots of the plant grow slowly.The farmer plow tillage cropping continuously for a long period of time. Without the use of organic fertilizer? The structure of soil is breaking down. The soil is dense in the end. The soil dense or poorly structured, despite much chemical fertilizer
.
so fertilizer was the main is the use of chemical fertilizer and organic fertilizer together is a good soil, and to plant the most.
