| Abstract: | The farmland fertility was totally lower with significant variation and bad nutrient circulation in soil quality and polluted seriously in some of farmland in Guizhou province. On the basis of analyzing the situation of Guizhou food security and the production potential of farmland, the new ideas were provided on nutrients management for farmland, such as implementing the techniques of regionalized nutrient management by means of the theory of nutrient precise management, balancing the nutrient supply in line with the integrated management technologies of nutrient resources, and establishing digital soil system and alarming system of farmland quality etc. |
