Effects of soil and water conservation, soil erosion and long-term storage of carbon in the soil, planting cassava coarse grained soil and farmers in Nakhon Sawan. Statistical analysis of variance for one factor to influence the way the system is composed of four methods of soil and water conservation and soil texture. The conservation of soil and ground water texture. The system conserves soil and ground water rough. And a coarse-grained soil and ground water. To study the effects of soil and water conservation to prevent soil erosion in the area. Compare the distribution and accumulation of carbon between soil and water conservation areas are areas where there is no long-term conservation of soil and water. And the relationship between carbon content distribution in the chemical and physical properties comparable between the soil parent materials from fine to coarse-grained areas with soil and water conservation on soil texture. In the upper area is likely to cause the accumulation of organic carbon in the lower and have a narrow range with an average of 21.60 grams per tonne. The area over which no systematic soil and water conservation, soil texture on average 18.13 grams per kilogram. The area's soil and water conservation system has ground to a coarse organic carbon accumulation in the upper and lower body closer together and have a wide range, with an average of 6.51 grams per tonne. The area over which no coarse soil and ground water. This will tend to accumulate organic carbon in the area can not lower than the cant upper range, range-wide, with an average 5.45 grams per tonne, and soil and water conservation on soil texture, making the loss of soil as little as possible. and yields of cassava up significantly on the statistics.
