Sewage Sludge Amendment Combined with Green Manuring to a Coastal Mudflat Salt-Soil in Eastern China: Effects on Soil Physicochemical Properties and Maize Yield

Figure 3

Effects of sewage sludge amendment (SSA) combined with green manuring on organic carbon (a) and CEC (b) of coastal mudflat salt-soil. Vertical bars indicate standard deviations of the means. Columns with different letters show significant difference between sewage sludge amendment rates at by LSD’s multiple range test. Values of are the test in ANOVA; . CEC, cation exchange capacity.
