METHOD OF DETERMINING THE SUSTANIBILITY PERIOD OF STOCKPILED MINED SOIL FOR PLANT GROWH IN MINING AREA

摘要

The method of determining the period of sustainability of stockpiled mined soil for plant growth in mining areas comprising the steps of measurement of soil properties such as texture, pore space, field moisture, field capacity, water holding capacity (WHC), wilting capacity, pH, electrical conductivity (EC), cation exchange capacity (CEC), Ca, Mg, Na, K, sodium absorption ratio (SAR), organic carbon (OC), phosphorous, microbial population required for plant growth on different aged stockpiled mined soil dumps and unmined land of similar geographical conditions, analysis of the deterioration of soil properties stockpiled mined soil with respect to time and finally determining the said period of sustainability as the time period till which the soil have the soil properties required plant growth as in case of mined soil of similar conditions.
