Other claims from this paper (17)
- Intervention effect Each shade tree association increased total litterfall.
- Intervention effect Shade tree association did not impact cocoa yield.
- Intervention effect Albizia shading had higher litter N.
- Intervention effect Milicia shading had higher litter P.
- Intervention effect Ceiba shading had higher litter P.
- Intervention effect Milicia shading had higher Ca.
- Intervention effect Ceiba shading had higher Ca.
- Intervention effect Canarium shading had lower litter pH.
- Intervention effect Dacryodes shading had lower litter pH.
- Intervention effect Canarium shade had no reported impact on soil properties.
- Intervention effect Dacryodes shade had no reported impact on soil properties.
- Intervention effect Albizia shade increased soil inorganic N and P content and bioassay results.
- Intervention effect Milicia shade increased soil inorganic N and P content and bioassay results.
- Intervention effect Ceiba shade increased soil inorganic N and P content and bioassay results.
- Intervention effect Milicia shade increased soil pH and total C and N content and yielded the greatest soil fertility increase.
- Intervention effect Ceiba shade increased soil pH and total C and N content and yielded the greatest soil fertility increase.
- Recommendation Farmers should use shade trees such as Milicia or Ceiba with high Ca cycling to improve their systems.
