Summary
Land evaluation for rice and sugarcane in Nam Phong, Cao Phong, Hoa Binh
Land production potential of sugarcane is highest in profile NP08 and NP10 with the soil type of glaic ferralic acrisols. The second soil type, which gives high potential yield is haplic ferralic acrisols. Adiation-thermal production potential of spring rice, summer rice and sugarcane was 4.9, 5.5 and 105.2 tons/ha. Water limited production potential of sugarcane is 61.2 tons/ha. Land production potential varied 2.6-4.0 tons/ha for rice and 39-54 tons/ha for sugarcane. Some area for sugarcane which is presented by profiles NP07, NP08 and NP10 were proposed. Other land unit still maintain rice cultivation to food security. To increase rice and sugarcane yield, it needs to improve soil to overcome some limitations such as texture, humus content, and CEC by some methods in order to increase organic matter content, establish irrigation and drainage system, apply balanced fertilizer, especially for P and K fertilizers.
