- W2383663430 abstract "The date of soil testing and formulating fertilization project and the second national soil survey were used to analyze the soil nutrient status and variation in Yingjiang County. The results showed that the farmland nutrients in Yingjiang for organic matter, total nitrogen, alkali-hydrolyzable nitrogen content and the average available phosphorus are rich, while the available potassium is deficient. Variation tendency revealed the soil organic matter and total nitrogen reduced to the secondary level and the alkali-hydrolysable N and available P increased but the available K decreased. The overall soil nutrient characteristic tends to acidification. Cluster analysis showed that the farmland soil could be divided into four categories, the first one is accounting for 3.87% of the total farmland, the soil with high organic matter, high nitrogen and phosphorus medium but potassium deficiency, and the second one is accounting for 13.39% of the total farmland, the soil with high organic matter and nitrogen and phosphorus reduced to the secondary level but lack of potassium, then the third one is accounting for 20.32% of the total farmland, which is the secondary producing area, the soil with medium level of organic matter and nitrogen and rich of phosphorus but lack of potassium, the last one is accounting for 62.42% of the total farmland which is the main producing area." @default.
