Price 479,000d Scientists often call people SX agriculture needs to return organic matter to the soil. The argument mainly long day if no fertilizer for soil organic matter, the soil will be getting worse ... Need to return soil organic language If scientists say they will be degraded land manifestation of character physical and chemical composition. Degraded land, the physical properties worsening structural manifestations up compacted or too fragmented, altered density, ability to retain moisture, water retention, poorly maintained distribution. Besides, soil color and increasingly gray, acidity increases, declining organic matter, resulting in soil nutrient depletion. Consequently, crop yields will decline. On the ground deteriorates despite investing more chemical fertilizers, the fertilizer efficiency will be worse. Therefore the productivity of rice and vegetables on gray soil or sandy soil fertilizer to 200 kg despite N / ha (approximately 435 kg of urea), it's not fertilize 80-100 kg N on alluvial soils. From the actual situation as so many people think that bottle chemical fertilizing the soil, making the land deteriorated, but did not see the essence is because growers do not pay attention returned to the soil as organic matter determinant. Reasons to apply chemical fertilizers alone partly because of scarce sources of organic fertilizer, if it does carry a lot of work, manipulating bulky, meanwhile convenient chemical fertilizer should multifaceted lack of harmony This two kinds of fertilizer when sowing. If we take the trouble to learn the coffee growers in the Central Highlands will reduce aversion to chemical fertilizers. Although the coffee growers in the Central Highlands is increasingly using more fertilizer, but who utilize organic matter returned to the soil through injection engineering plant residues in coffee garden, mulch for coffee , manure for fertilizing more coffee per capita estimates kinds about 8-10 tonnes / ha / year. Thus the average annual Highland provinces have used nearly 3 tons of chemical fertilizer types / ha of coffee that coffee cultivation has not been degraded, yields the following year was higher than last year. Please cited survey data of Ton Nu Tuan Nam stated in the report "Findings of scientific solutions - technological and socio-economic in the Highlands" is clear. The report said that the average chemical fertilizer was applied to coffee in the Central Highlands province's 4 416 kg N (equivalent to 904 kg urea / ha), 248 kg P205 (equivalent to 1,550 kg of super phosphate) and 239 kg K20 (equivalent to 398 kg of KCl / ha). A total of 3 types of chemical fertilizer this figure was 2,852 kg / ha / year. If we compare the distribution was applied to rice and maize and other crops are far less manure to fertilize the coffee. This does not mean just encourage more fertilizer applied to crops, but only to clarify the meaning of organic combination of all kinds that are reasonable, even with chemical fertilizers in high doses, the Nor is the culprit as bad bottle land as land or people used to think. Note the inclusion of straw However we also note that, if no manure to manure decomposed that identification must bury manure or straw tree freshly made on land only or land paddy crop but is exposure to new fields drain safe and effective. Where necessary to bury fresh straw must plow the earth immediately, after 1 month to sowing, attention limed, add phosphorus than normal, and when rice growing is 15, 30 days to drain dry farm about 5-7 days to be able to achieve high yield and stability. Results buried straw (North called plow still out) or bury the green manure crops have been the home of the Institute of Agriculture and Fertilizers and soil chemistry research on many soils in the north from before the liberation of the South. Research results have recommended that, burying fresh straw or manure in the soil is not toxic to plants. But on continuous wetland that time is short, buried very toxic for plants. Recently Vu Tien Khang et al (2005) and Nguyen Thanh Hoi (2008) and again proved that if fresh straw buried in continuous wetland, due to anaerobic conditions resolution process takes place very slow. Buried up to 90 days but is still 37% of the straw has not been resolved. In fact 63% of straw is called degradation in stage only sold resolution. Because of the decomposition of fresh straw produces more toxins as H2S, CH4, C2H4, volatile organic acids and nonvolatile pretty much should have been toxic to the roots, hindering the growth and development of plants, leaves and roots used to make a die, an effective rate lower branches, a high flat rate, leading to a lower yield rice straw stripped from rice fields about 40% (for Experience in pots) and about 17-20% (field experiments). Meanwhile if fresh straw buried in paddy sowing HT but after 15 days, or 30 days have drained dry land after about 5 days, the paddy recover pretty fast and more productive agricultural land to water regularly about 19 %. So in flooded fields, making rice HT, without draining dry farming conditions are best brought out straw from fields, or may be forced to burn up the chaff with burn evenly and thoroughly before soaked soil plowed field about 1 month to sowing rice
