Other claims from this paper (11)
- Observation Leucaena leucocephala can fix 134–274 kg nitrogen per hectare per year in the field.
- Observation Gliricid,a sepium can fix 134–274 kg nitrogen per hectare per year in the field.
- Observation Genotypes and microbial symbionts differ in nitrogen fixation and tolerance of low phosphorus and high acidity.
- Association Pruning regimes affect nitrogen fixation and its contribution to the nitrogen cycle.
- Observation New nodules formed during regrowth after pruning.
- Observation About half of fixed nitrogen is in belowground plant parts.
- Observation Hedgerow prunings yielded over 300 kg nitrogen per hectare per year.
- Observation Prunings contributed 40–70 kg nitrogen per hectare per season to crops.
- Observation Nitrogen contributed to crops represented about 20–30% of nitrogen applied as prunings.
- Observation Root turnover and nodule decay were estimated to transfer 25 kg nitrogen per hectare to soil.
- Mechanism Crop nitrogen-use efficiency was low because crop demand and nitrogen supply from prunings were poorly synchronized.
