The team, after carrying out nearly 30 years of inspection on experimental sites in six typical provinces, has found spatial and temporal variations of farmland acidification, established three key technologies centering on the accurate application of lime materials and animal manure, and the reduction of chemical nitrogen fertilizers application to control such acidification. The team also developed new amendments for acid soil and integrated farmland acidification control technology modes featuring regional characteristics. These models have been widely promoted for their prominent economic and ecological effects.
