Sewage sludge amendment is an innovative solution for new arable land resources and solid waste disposal. Sewage sludge as an initial fertility driver combined with planted and tilled green manures decreased salinity and pH, and increased OC, N and P concentrations in mudflat soil. The initial fertility driver increased grain yield of maize Heavy metals concentrations in grain of maize did not exceed the safety standard for food.
