Abstract
Growth of Agathis dammara (Lamb. Rich.) seedling on gold tailing with addition of coconut shell charcoal and compost
Highlights
The natural resources is divide into two catergories
It indicated that the addition of coconut shell charcoal from 0 g to 25 g and the addition of compost about 20 g, 40 g, to 60 g could support the growth of A. dammara seedling as well in the tailing medium
This phenomenon probably due to A. dammara’s root was stimulated by the lack of nutrient. These facts indicated that compost palyed an important role toward the A. dammara growth, which planted in the tailing
Summary
The natural resources is divide into two catergories. Those are the renewable natural resources and non-renewabl (depletable) natural resources. Non-renewabale natural resouce is the natural resource which does not have ability on biologically regeneration or can not renew if its sources have completed in the nature. It is formed by the geological process with a long time (period) to be available again and ready to be used (Fauzi, 2006). The tailing improvement can be conducted by the addition of coconut shell charcoal and compost. The addition of coconut shell charcoal and compost aim to improving the soil (medium) structure, increasing macro and micro nutrient, and decreasing heavy metals contents (Yuniwati et al, 2012; Wasis and Istantini, 2013; Winata et al, 2016). The aims of this study were to analyze the growth of A. dammara seedling in the tailing and to analyze the influence of coconut shell charcoal and compost increament toward the A. dammara seedling growth in the tailing
