The BCR continuous extraction was used to research the soil Cu and Zn contents change and its spatial variability after 31-year fertilization treatments on Shenyang Agricultural University brown earth long-term localization experimental field.The experimental results showed that compared with the baseline
the contents of the water soluble Cu
the weak acid soluble Cu and residual Cu decreased
the contents of oxidizable Cu and reducible Cu decreased in fertilizer area while in organic fertilizer area the tren...
