Interpretive Summary

2012

Balanced Fertilization Technology in Sweet Potato, 2012 Sweet potato cultivation is quite extensive in China. But in many sweet potato growing regions, the application rates of fertilizers, especially K, are very low. According to our survey, many farmers applied compound fertilizers, like 15-15-15, to sweet potato instead of other commonly available K fertilizers (like KCl) because of high prices. This has led to a situation where there is under application of K in sweet potato in China.

Research on Balanced Fertilization Technology of Sweet Potato, 2011 This project aimed to increase sweet potato yield and quality through optimum fertilization, and establish the soil nutrient classification indexes and demonstrate balanced fertilization technology for sweet potato. Field trials were carried out in Guanyun county and Liuhe district of Nanjing, Jiangsu province by Jiangsu and Hubei Academy of Agricultural Science in 2011.
