Abstract

The effects of two Niger Delta Mangrove Swamp Soils on growth and growth components of Rhizophora mangle were studied. The mud flats had higher manganese, organic carbon, lower sodium, higher phosphorus, lower pH and no sand particle compared with peaty clays. The mud flats also had very low cation exchange capacity (CEC) and these qualities affected adversely the plant height, survival, disease index and stability of the plants compared with those grown in peaty clays. Recommendations for improvement of the mud flats for mangrove swamp re-vegetation are made.

Key words: Red mangrove species, mangrove swamp soil, survival rate
