RECLAMATION OF SALINE SOIL BY USING LOCALLY AVAILABLE ADMIXTURES: MARALGOE NIFAD

Abstract

Salinization is measure problem in agricultural soil. Salinization of soil is caused due to the use of chemical pesticides, fertilizers and climatic conditions such as high temperature and low rainfall. Climatic conditions and use of chemical pesticides are affected on the environment. In this paper saline soil samples was collected from Mralgoe, Nifad. Pot experiment was conducted to reclaim saline soil. Individual and combination of admixtures are used in this study. Locally and cheaply available admixtures were added at 2cm depth layer in each pot. Seven treatments were given, such as T1(control), T2(soil + cow dung), T3(soil + kitchen waste), T4(soil + garden trimming) T5(soil + fly ash), T6(soil + coal powder), T7(soil + cow dung + kitchen waste + garden trimming + fly ash + coal powder). Leaching treatment were provided after 8,16,24,32 days of leaching. pH, electrical conductivity, sodium adsorption ratio, bulk density of the soil were calculated after 8,16,24,32 days of interval. After adding admixtures, combination of admixture gives better result than the single one. Cow dung is helpful for changing the pH and electrical conductivity of soil. Cow dung playing the important role for decreasing the value of total petroleum hydrocarbons. Fly ash changing the bulk density of soil. Coal powder is helpful for decreasing the electrical conductivity.
