Abstract

Bioremediation has a great potential in reducing environmental degradation. This is also a strategy used in mitigating climate change through carbon sequestration. This study assessed the biomass and carbon accumulation of Acacia mangium and Eucalyptus urophylla as influenced by commercial mycorrhizal inoculants. Seedlings were inoculated with mycorrhizal inoculants produced locally or obtained abroad, grown in a screen house for 6 months and planted in a mined-out area in Mogpog, Marinduque. The total plant biomass after 27 months in the field was computed using the allometric equation by Martinez-Yrizar et al. (1992). Results showed that A. mangium inoculated with Mycogroe (local inoculant) has the highest total biomass of 33.65 t ha-1 and CO2, of 55.52 t ha-1. This is 121.46% increase relative to its control counterpart with biomass content of 15.19t ha-1, C of 6.84 t ha-1 and CO2 of 25.07 t ha-1. On the other hand, Mykos30 (abroad) inoculated E.urophylla has a biomass build-up of 11.05 t ha-1, C and CO2 density of 4.97 t ha-1 and 18.23 t ha-1, respectively. The uninoculated E. urophylla counterpart had a biomass density of 5.30 t ha-1 with 2.38t ha-1 of C and 8.74 t ha-1 of CO2 stored. The value showed 108% increase in total biomass and stored carbon, relative to the uninoculated ones. These findings suggests that accumulation of biomass and the ability of trees to sequester atmospheric carbon in degraded areas are enhanced by mycorrhizal inoculation.
