Other claims from this paper (11)
- Intervention effect N and PK fertilization appeared to increase N mineralization without statistical significance.
- Intervention effect N additions significantly increased soil inorganic N concentration.
- Mechanism Authors infer a sustained increase in site quality from repeated fertilization.
- Mechanism Increased mineralization can partly meet greater uptake demand in heavily fertilized plots.
- Recommendation Fertilizer application could theoretically be reduced without reducing uptake rate.
- Intervention effect Growth responses to improved nutrients were significant despite moisture limitation.
- Association Moisture limitations probably reduced growth responses.
- Method / resource Laboratory gross mineralizable N estimates agreed with field estimates.
- Association Gross mineralizable N correlated more closely with foliar N than in situ mineralization.
- Method / resource Net mineralizable N estimates disagreed with field sequential coring data.
- Method / resource Sequential coring requires intensive spatial and temporal sampling.
