Application of husk charcoal for waste risk minimization by growing Acacia mangium (Willd.) on gold mining media

Abstract

Husk charcoal is a crop waste that can be used to improve tailings media. Tailings have several characters including, low organic matter content, low microorganism activity, low essential nutrient content, low cation exchange capacity and high heavy metals. The design used in this experiment was a complete randomized design factorial with 2 factors. The first factor was the husk charcoal and the second factor was the application of compost fertilizer. The treatment of husk charcoal and compost did not significantly affect the growth of total dry weight and root Chapter contents Introduction ……………………………………………………………………………………………………..
