From: Sewage sludge application enhances soil properties and rice growth in a salt-affected mudflat soil

Effects of sewage sludge (SS) application on the concentration of soluble sugar (A) and amino acid (B) in the bleeding sap of rice plant in salt-affected mudflat soil. Columns with different letters show significant difference between SS application rates at p < 0.05 by LSD’s multiple range test.
