Other claims from this paper (19)
- Observation Garden sorrel (Rumex acetosa) harvested with a high leaf-to-stem ratio had high P concentration.
- Observation Dyer's woad (Isatis tinctoria) harvested with a high leaf-to-stem ratio had high P concentration.
- Observation Fodder radish (Raphanus sativus) harvested with a high leaf-to-stem ratio had high P concentration.
- Observation Cruciferous crops had high S concentration.
- Observation Dyer's woad had high boron (B) concentration.
- Observation Salad burnet (Sanguisorba minor) had high boron (B) concentration.
- Observation Stinging nettle (Urtica dioica) had high boron (B) concentration.
- Observation Dandelion (Taraxacum officinale) had high potassium (K) concentration.
- Observation Chicory (Cichorium intybus) had high potassium (K) concentration.
- Observation Garden sorrel had high potassium (K) concentration.
- Intervention effect Green manures with high P and S concentrations increased nutrient uptake and yield of pot-grown cauliflower.
- Association Cauliflower production decreased when the C:N ratio of applied green manure increased.
- Association Kale production decreased when the C:N ratio of applied green manure increased.
- Intervention effect Application of 160 kg N ha –1 in early harvested lucerne gave the highest kale production.
- Intervention effect Application of N in late harvested lucerne with a C:N ratio of 20 produced 34% less kale production than early harvested lucerne.
- Mechanism Differences in vegetable production were due to N availability rather than the amount of N applied.
- Association For leek, the C:N ratio of fresh, ensiled or dry green manure has to be low to get a fast response.
- Association For celery, the C:N ratio of fresh, ensiled or dry green manure has to be low to get a fast response.
- Recommendation It is possible to produce green manures with high concentrations of S, P, K and B and low C:N ratios.
