This work investigated the kinetics of Carbon and Phosphorus Mineralization in Wetland Soils amended with water Hyacinth (Eichhnornia Crassipe). The work studied the effects of water hyacinth also known as Eichhornia Crassipe on Carbon and Phosphorus Mineralization in Delta Wetland soil. The kinetics of Carbon and Phosphorus Mineralization was studied using Pseudo Second Order Equation. The Respiration Assay of the organic matter (Water Hyacinth) incorporated leads to emission of carbon in the form of carbon (iv) oxide and greater degree of microbial activities than those occurring in the control Soils after initial stage of incubation. Reaction Rates decreases with time in the amended Soil. In all the Soil samples, initial rapid phase of mineralization was clearly observed. Phosphorus Mineralization increased gradually with time in the amended soil as a result of high degree of organic matter and the pH of the soils.
