e2“there was a tendency that SOC, total N, total phosphorus (P), available P, and available potassium (K) were higher at the upslope than downslope side of tree-grass rows”
e0“maize height, grain yield, and leaf nitrogen (N) concentrations were significantly higher at the upslope than downslope side of tree-grass rows”

Other claims from this paper (6)
- Observation Maize height, grain yield and leaf nitrogen concentrations were higher on the upslope than the downslope side of tree-grass rows.
- Observation Grain yields were 30–35 % higher on the upslope than the downslope side.
- Observation Available P and available K tended to be higher on the upslope than the downslope side of tree-grass rows.
- Mechanism Forage grass strips trapped nitrogen and other nutrients and enhanced nutrient use efficiency in the agroforestry.
- Observation Maize performance and soil fertility mid-way between tree-grass rows were comparable to sole-crop maize.
- Recommendation Such variability should be considered for effective application of nutrients in agroforestry.
