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.
Key words: Soil Salinity, Soil Reclamation, Compost
