Aplikasi Amelioran Tanah dan MycoSilvi pada Falcataria sp. dan Ochroma bicolor Rowlee. untuk Reklamasi Lahan Pascatambang Pasir Silika

Abstract

Open pit mining of silica sand causes some soil degradations and environmental impacts, such as lowering soil pH, lowering soil fertility, soil compaction, and toxicity of micronutrients such as Al, Fe, and Zn. The aim of this study was to analyze the soil properties of land post mining of silica sand and to analyze the growth response of Falcataria sp. and Ochroma bicolor by combination of soil ameliorant and MycoSilvi. The experimental design was split plot design of two treatment factors, MycoSilvi and soil ameliorant. The main plot is MycoSilvi that consist of two levels (MycoSilvi and without MycoSilvi). The subplot is soil ameliorant that consisted of six levels (compost 0 g, lime 0 g; compost 0 g, lime 1.56 g; compost 0 g, lime 3.12; compost 9 g, lime 0 g; compost 9 g, lime 1.56 g; compost 9 g, lime 3.12 g). The results showed that the soil ameliorant (lime 3.12 g and compost 9 g) and MycoSilvi was the best treatment to increase height, diameter, biomass, and mycorrhizal colonization of Falcataria sp. and O. bicolor.

Arbuscular mycorrhizal fungi inoculum and soil ameliorants enhance the growth of Falcataria moluccana in revegetation of post-silica sand mining land in Sukabumi, Indonesia

“…The symbiosis of Arbuscular Mycorrhizal Fungi (AMF) with plants could support plant growth by increasing nutrient uptake, especially P (phosphorus). MycoSilvi is an AMF inoculum enriched with Mycorrhizal Helper Bacteria (MHBs), which we developed, to significantly increase phosphorus uptake, plant height, and stem diameter in postsilica sand mining in greenhouse experiments (Budi et al 2020;Munawaroh et al 2020). Therefore, it is necessary to test their effectiveness in the field.…”
