Other claims from this paper (11)
- Observation Soy sauce cake and desalted cake had about 42 mgN/gDW nitrogen, equivalent to poultry manure.
- Observation Soy sauce cake and desalted cake contained less P, K, Ca and Mg than poultry manure.
- Intervention effect Ammonium sulfate rates did not affect potato growth or N, P, K and Mg concentrations.
- Intervention effect Increasing soy sauce cake rates tended to increase plant dry weight and tuber yield.
- Intervention effect Increasing desalted cake rates tended to increase plant dry weight and tuber yield.
- Intervention effect Increasing poultry manure rates tended to increase plant dry weight and tuber yield.
- Intervention effect The highest soy sauce cake rate did not increase flowering-stage dry weight, possibly because of salt stress.
- Intervention effect Soy sauce cake raised nitrogen concentration in plant parts and petiole juice nitrate.
- Intervention effect Desalted cake raised nitrogen concentration in plant parts and petiole juice nitrate.
- Intervention effect Poultry manure raised nitrogen concentration in plant parts and petiole juice nitrate.
- Recommendation The authors advise caution with high soy sauce cake doses because of salt stress and soil salt accumulation.
