Effect of Adding Dilute Sulphuric Acid on Calcareous Soil Properties in Jordan Valley

Abstract

Calcareous soil that contains enough free calcium carbonate to effervesce visibly, releasing carbon-dioxide gas, when treated with diluted sulfuric acid. Analysis of calcareous soil in Jordan valley after treatment with aqueous low concentration sulfuric acid shows some change in the physical prosperities of the soil such as reduction of calcium carbonate from 66% to 30%, soil density from 1.60 g/cm3 to 1.19 g/cm3 . Soil texture is convert from silt clay loam to silt loam this physical changing makes soil permeability is easier so it could be suitable for agricultural without effect in plant growth also we show reduce soil PH and increasing in soil filtration tare. We showed several changes in the plants, which planted in the treated soil by sulfuric acid as increasing in the product from 10 - 25 %, would reduce in using chemical fertilizers from 15-30% and absence of soil diseases.
