Biological activity of soil under rubber plantations in Côte d'Ivoire

Abstract

Potential rates of C and N miner- alisation were measured in the laboratory on homogenized soil samples, using the standard method described by Dommergues (1960). Soil was moistened at field capacity, placed in a sealed box and kept at 28°C. The C0,evolved was &ed with NaOH and titrated with hydrochloric acid. The net amount of CO2 evolved from the soil was calculated after deducting
