Other claims from this paper (16)
- Intervention effect Conventional management greatly increased wheat yields.
- Intervention effect Conventional management reduced mycorrhizal colonisation of wheat.
- Intervention effect Superphosphate reduced mycorrhizal colonisation of wheat.
- Observation Grain N, K and Mg concentrations showed only minor variations.
- Observation Grain Ca, S and Fe concentrations showed only minor variations.
- Intervention effect Conventional wheat grain had lower Zn and Cu than organic grain.
- Intervention effect Conventional wheat grain had higher Mn and P than organic grain.
- Mechanism Soluble P fertilisers were interpreted to increase P uptake.
- Mechanism Reduced mycorrhizal colonisation under soluble P fertilisers was interpreted to reduce Zn uptake.
- Mechanism Reduced mycorrhizal colonisation under soluble P fertilisers was interpreted to enhance Mn uptake.
- Mechanism Lower Cu was attributed to dilution in heavier crops.
- Mechanism Past lime applications on the organic farm were interpreted to decrease Mn availability.
- Observation Grain mineral variations had nutritional implications primarily favouring organic wheat grain.
- Intervention effect Organic management did not induce dramatic grain mineral concentration increases.
- Intervention effect Eliminating soluble fertilisers did not induce dramatic grain mineral concentration increases.
- Association Organic management was associated with yield reductions of 17–84 per cent due to P limitation and weeds.
