Forest Structure, Nutrients, and Pentaclethra macroloba Growth after Deforestation of Costa Rican Lowland Forests

Table 2

Comparison of the relative contribution (RC) of soil dissolved organic carbon (DOC), carbon dioxide (CO₂), and microbial biomass (Biomass) within primary and secondary forests with P. macroloba as the dominant N-fixing tree within the MNWLR of Costa Rica. The difference in the RC values is expressed as the ratio of RC primary to RC secondary. The ratio of the RC values for biomass to CO₂ and to DOC is given for both the primary and secondary forest soils. From these values, a comparison is given of the ratio of values biomass to CO₂ and biomass to DOC, comparing the primary to secondary forest values.


	Total	RC primary	RC secondary	Difference in RC, primary to secondary

DOC	1773.89	0.35	0.65	0.55
CO₂	6.69	0.25	0.75	0.34
Biomass	621.04	0.65	0.35	1.86

Ratio of RC values		Primary	Secondary

Biomass to CO₂		2.55	0.47
Biomass to DOC		1.83	0.54

Ratio of RC comparing primary to secondary forest stands

Biomass to CO₂		5.43
Biomass to DOC		3.38
