Other claims from this paper (11)
- Intervention effect High phosphorus and unstressed moisture gave the highest wheat grain and straw yields.
- Intervention effect Following pea yield did not respond to residual copper and zinc.
- Intervention effect Micronutrient fertilization increased copper and zinc concentration in wheat grain and straw.
- Intervention effect Micronutrient fertilization increased copper and zinc concentration in pea grain and straw.
- Intervention effect Micronutrient fertilization increased after-harvest soil copper and zinc availability and supply.
- Observation Added copper was substantially occluded with organic matter.
- Observation Added zinc was substantially occluded with oxyhydroxide species.
- Observation Carbonate-associated copper and zinc dominated soil speciation.
- Observation Copper acetate and methoxide species were identified in the soils.
- Observation Zinc-sorbed montmorillonite species were identified in the soils.
- Observation Insoluble copper phosphate and zinc phosphate complexes were not identified and appeared unlikely to control availability.
