Abstract
Based on the results of long-term (10 years) field experiments of potassium (K) application under three cropping systems including rape seed-early rice-later rice, middle rice-wheat, cotton-wheat in Hubei Province, the effect of long-term K application on the yields and profits of the crops is indicated in this paper. The influence of long-term K application on K contents and status in soil is also discussed.关键词
