Abstract
The effect of forest soil (2.5 kg/pit) and mine spoil alone (control) on performance of three nitrogen fixing trees, viz., Acacia mollissima, Leucaena leucocephala and Robinia pseudoacacia in limestone mine has been studied. The study reveals that Robinia pseudoacacia gave maximum survival (97.92%), whereas, height growth was observed maximum (3.98 cm) in Acacia mollissima. The addition of forest soil positively influenced the survival, height and biomass of all the above species, however, diameter and root: shoot ratio was more in mine spoil alone (control).
