Other claims from this paper (10)
- Observation Late varieties gave greater root and litter carbon input.
- Observation Late varieties responded more strongly to phosphorus.
- Intervention effect Phosphorus increased root and litter carbon by 44–49%.
- Observation Root and litter carbon formed 60% of total input.
- Observation Soyabean could not maintain soil organic carbon at 70% annual decomposition.
- Intervention effect Phosphorus supplied 105–107% of carbon needed to maintain soil organic carbon under 50% decomposition.
- Observation Increasing soil organic carbon by 1 g kg−1 was estimated to require 12.2–14.2 Mg ha−1 carbon.
- Observation Varietal carbon input represented 7–22% of the required input.
- Intervention effect Phosphorus reduced the carbon required to increase soil organic carbon by only 4–10%.
- Observation Soyabean carbon input remained minimal despite greater duration and phosphorus.
