Preliminary Studies on Revegetating the Mine Spoils of ACC Limited, Madukkarai Cement Works

摘要

During the last two decades, the number of cement factories has increased hugely due to expanding requirement of cement materials for construction. A study was taken in ACC cement works, Madukkarai, Coimbatore to assess the floristic composition of shrubs, herbs and tree species that are available in both mine out soils and soils nearby the factory vicinity. A pot experiment was conducted to find the effect of different biofertilizers on the growth of tree seedlings with potting mixture of minespoil, garden soil and vermicompost in the ratio 1:1:1 on volume basis. The results revealed that the application of phosphobacteria @ 10 g/seedlings enhanced the growth of seedlings to about 20 percent over the control. Therefore, it was concluded that utilizing biofertilizer with proper potting mixture can help to revegetate the mined out spoils of cement industry.
