PENGARUH ABU TERBANG BATUBARA TERHADAP SIFAT KIMIA TANAH DAN SERAPAN TIMBAL (Pb) OLEH TANAMAN AKAR WANGI (Vetiveria zizanioides L.)

Coal fly ash is a soil amendment that can be used to improve productivity because coal contains essential nutrients needed by plants. However, also heavy metals. This study was at time explore the effect of on chemical properties and lead uptake vetiver plant (Vetiveria zizanioides L.). Treatments tested were applications six proportion levels (0, 2.5, 5., 10, 15, 30% weight). The seven treatments arranged in completely randomized design with three replicates. result showed had significant pH, total-P, total-N, total-K Pb. value Pb translocation factor from roots shoot relatively low, so not suitable for use phytoextraction Pb-contaminated soil.
