| Converting Upland Rice Fields to Rice Terraces in Slopping Area is one of the chosen rice planting system for sustainable rice cultivation on the mountainous area in the upper northern of Thailand. It can increase more double yield than from the upland rice . Water preserving and soil fertility problems are always found in Converting Upland Rice Fields to Rice Terraces in Slopping Area. Studying water and rice nutrient management in Samoeng Rice Research Center was founded that the yield from 5 water regime treatments were not significantly. For rice nutrient management, the yield from adding phosphorus combination with potassium chemical fertilizer was not significantly with adding nitrogen combination phosphorus and potassium chemical fertilizer. But the... |

| Measurement of methane emission from major rice production systems is a methodology for data collection of carbon footprint from rice production system. Five major rice production systems were defined for methane emission measurement in 2011 rainy season, including upland rice, rainfed rice, irrigated rice, good agricultural practices (GAP) rice production, and organic rice. Gas samples were taken at one week interval and analyzed by Gas Chromatograph, GC-8A as soon as possible after collection. The research found that upland rice could absorb CH4 at the rate of 90 tons per crop equivalent to 2,258 of CO2. Rainfed rice production system occupied most of rice area in Thailand emitted CH4 at the rate of 58,127 tons per crop equivalent to 1,453,180 tons... |
