Reclamation of Saline Soils using Composted Organic Wastes

Abstract

Abstract: Soil salinity is one of the problems that affects crop production in Sudan and results in yield deterioration. Remediation techniques practiced in saline soils usually expensive and need high technology. In order to apply a cheap method, composted organic waste was applied to saline soil treated with different concentration of Sodium chloride (NaCl) solution. Compost was applied with different application rates. The mixtures were incubated for 4 weeks and irrigated with So ml water. Samples were analyzed and the results revealed that the application of compost should be done with the recommended doses in order to reclaim saline soils as high compost application rate might increase salinity of soils. Quality control measures of composts should be implemented before compost use. Therefore, it is recommended that compost can play major role in soil reclamation especially of saline soils as it is environmentally safe and cheap compared to other reclamation procedures.
