Other claims from this paper (10)
- Intervention effect Fallowing and green manuring improved first-crop sugarcane yields to 141–144 t ha −1 from 129 t ha −1.
- Intervention effect First and second ratoon yields showed no significant responses.
- Intervention effect Fallowing increased first-crop root length index to 5.2–6.8 km m −2 from 3.5 km m −2.
- Observation Improved rooting persisted in the first ratoon where soil dried during fallowing.
- Intervention effect Fallowing did not affect soil bulk density, total porosity or water-holding capacity.
- Intervention effect Fallowing increased air-filled porosity from 11 % to 16%.
- Intervention effect Fallowing increased steady state ponded infiltration rates to 1.34 mm h −1 from 0.61 mm h −1.
- Observation Soil organic matter declined in all cases, probably due to tillage.
- Association Plant-crop root length correlated with air-filled porosity.
- Recommendation The authors emphasize improving belowground air supply for production on poorly draining clay soils.
