Abstract
Three alley cropping treatments were tested and compared with current farmers' practice in a highly eroded sloping land in the Philippines. The soil of the study site was loamy, with a high content of exchangeable bases but very low content of C and N. This study replicated the experiment conducted at another hillyland site with different soil characteristics.
The results obtained st this site support the observation made in the other experimental area in relation to the alleviation of soil and nutrient losses and increase in biomass production. Likewise, the alley cropping practice did not lead to any improvement of the soil chemical properties within the three-year experimental period.
