Los nutrimentos del suelo y la diversidad de especies de árboles en los bosques de Costa Rica
Analysis of published data for forty-six Costa Rican forest sites indicates a negative correlation between soil nutrient availability and tree species richness. P, K, Ca, Na, total bases, base saturation, and cation exchange capacity showed significant (P<0.01) correlations, while available nitrogen, total nitrogen, organic matter, Mn, and Mg were not significantly correlated with species richness. With measures of soil nutrients, a stepwise regression gave an R2 of 0.71. Correlations between species richness, precipitation, tree density, tree height, and soil fertility, are consistent with the interpretation that the highest species richness occurs under poor growth conditions. Results of field and glasshouse fertilization experiments are reviewed
