Effect of Tree Species and Organic Manures on Physio-Chemical Properties of Coal-Mine Soil and Seed Germination

The present study was attempted to document the influences of three tree species viz., Dalbergia sissoo (shisham), Gmelina arborea (ghamari) and Acacia nilotica (babul) and organic manures such as vermicompost, farm yard manure and poultry manure on physicochemical properties of coal mine soil. Coal mine soil amendment mix was prepared and used as top layer in all treatments. The organic amendments viz. vermicompost (VC), farm yard manure (FYM) and poultry manure (PM) were applied uniformly @ 0, 20, 40 and 60 kg as a top layer. Top soil amendment was also used as one of treatments along with species and organic manures. Treatments were studied as individual and different combinations of treatments. Ninety viable seeds of each test species were sown in each treatment and each treatment replicated three times. The tree species, top soil and organic manures had significant positive effect on physico-chemical properties of coal soil. Highest seed germination of all test species was in control and D. sissoo had highest germination percent. Organic amendments and tree species had significant effect in coal mine soil amelioration and re-vegetation on it.
