Van Chan district, Yen Bai province is a typical farming on sloping land in the Northern Mountainous. Almost lands here are slopes with thick soil farming community by H’mong, Muong, Thai people usesing. Crops in cropping systems mainly are maize, cassava and upland rice. Type of farming is to clean up and burned before planting, the ground exposed and not covered. So the presence of nutrient-rich soil organic matter eroded and washed away after rains is very high, reducing crop yields and soil degradation [2]. The application management solution integrated soil nutrients through organic cover (7 tons/ha) with balanced fertilization, reasonable yields of corn 24.4% respectively 16.7% profit increase compared to controls. Along with the technical fields, classification techniques and corn harvest processing, preservation corn helped keep the high quality and profit increases on 2.0 millions/ton after harvesting 4 months; total profits increased 9.988 millions/ha, equivalent 79.6% over the control. In addition, methods of operation through market information processing of meetings has helped farmers to produce corn with more choices in determining price, consumer services and stretch to avoid injury from price pressure. The results of the study have contributed to the strategy of sustainable agricultural production in Northern Mountainous of Vietnam, especially for commodity corn.
