The role of mycoSilvi and silvicultural treatment towards the growth of Albizia chinensis in post-mining area

Abstract

Open-pit mining causes decreased soil quality, low land carrying capacity, and reduced soil fertility, chemical properties, and soil texture. This study aimed to identify the chemical properties of the soil and analyze the growth response of Albizia chinensis against the most optimal combination of MycoSilvi and silvicultural treatment. In this study, a randomized block design consisting of two factors, namely MycoSilvi and silviculture was applied. Each treatment was repeated five times. The results showed that the interaction of Mycosilvi and post-planting soil tillage treatment (M1D1P0) and the interaction of MycoSilvi, post-planting soil tillage, and compost fertilizer (M1D1P1) obtained the best results in terms of height and diameter, with a significant increase of 83.16% and 115.94% compared to control plants, respectively. In addition, the combination of Mycosilvi and silvicultural treatment exhibited the highest mean number of spores. In general, AMF denoted a favorable percentage of root colonization with an average of 30.62-46.96%. Furthermore, pH in the combination of post-planting soil tillage and compost fertilizer (C0D1P1) 3.66 was higher than in the control (C0D0P0) 3.10 and the P-available soil in the combination of MycoSilvi, post-planting soil tillage, and compost fertilizer (M1D1P1) was greater 45.3 ppm than control on post-silica sand mining land.
