[HTML][HTML] Short-term dynamics of soil organic matter fractions and microbial activity in smallholder potato-legume intercropping systems

Continuous cultivation of potato (Solanum tuberosum L.) in monoculture systems represents
the greatest factor deteriorating soil organic matter (SOM) in smallholder farms. With an aim
to breaking this norm, a 2-year field trial intercropping potato with two legumes: lima bean
(Phaseolus lunatus) and dolichos (Lablab purpureus), was conducted in the upper-midland
(1552 meters above sea level (masl.)), lower-highland (1854 masl.) and upper-highland
(2552 masl.) agro-ecologies of Kenya. Residues from each cropping system were quantified …
