Abstract:

The effects of the application of compound fertilizer and compound fertilizer-improved liquid fertilizer on the changes of soil pH, cation exchange capacity, exchangeable calcium and magnesium, available copper, manganese, zinc, iron, plumbum, cadmium, chromium, nickel in the cherry-tomato acid soilwere studied. The application of improved liquid fertilizer could increase the treated plot soil pH, cation exchange capacity and exchangeable calcium significantly compared with the control, and decrease the soil available copper significantly, but had little effects on soil exchangeable magnesium and available manganese, zinc, iron. The improved liquid fertilizer would not produce damage of plant element deficiency or excessive during the fertilization process. It could be used in the Open-air field acid soil instead of some conventional fertilizers.

Key words: Open-air field acid soil, improved liquid, cherry-tomato, pH, mineral elements
