Impact of Long-Term Forest Enrichment Planting on the Biological Status of Soil in a Deforested Dipterocarp Forest in Perak, Malaysia

<table>Ratio of microbial biomass C to microbial biomass N (MBC/MBN) between the same soil depths at enrichment planting (F1) and secondary forest (F2) plots. Different letters indicate significant difference between means of the same soil depths comparing enrichment planting (F1) to secondary forest (F2) plots, using the Student’s <i>t</i>-test (<svg height="12.4875" id="M13" style="vertical-align:-1.29163pt" version="1.1" viewbox="0 0 56.150002 12.4875" width="56.150002" xmlns="http://www.w3.org/2000/svg">
