Abstract
Open mining of silica sand causes some environmental impacts such as declining levels
of soil fertility, lowering soil pH, and increasing toxic acid mine waste such as Al, Fe,
Cu, and Zn. Soil quality may be improved by the addition of soil ameliorant and
MycoSilvi, an inoculum of arbuscular mycorrhizae enriched by mycorrhizal helper
bacteria. This study aimed to analyze the growth responses of Falcataria moluccana,
Samanea saman, and Cassia siamea seedlings by the addition of soil ameliorant and
MycoSilvi grown in soil media from silica sand post mining. The experimental design
used in this study was completely randomized design with split pot design that consists
of two treatment factors (MycoSilvi and soil ameliorant) with five replications. The
main plot was MycoSilvi that consists of two levels (without MycoSilvi and with
MycoSilvi). The subplot was soil ameliorant that consists of six levels [(1) compost 0
g and lime 0 g, (2) compost 0 g and lime 3.6 g, (3) compost 0 g and lime 7.2 g, (4)
compost 32.5 g and lime 0 g, (5) compost 32.5 g and lime 3.6 g, and (6) compost 32.5
g and lime 7.2 g]. The interaction of MycoSilvi and soil ameliorant significantly
increased height, diameter, biomass, chlorophyll content, and mycorrhizal colonization
of F. moluccana, S. saman, and C. siamea. The MycoSilvi and soil ameliorant (32.5 g
of compost and 7.2 g of lime) was the best treatment for the growth and chlorophyll
content of F. moluccana, S. saman, and C. siamea study species.
