Title
Nutrient Uptake and Use Efficiency of Irrigated Rice in Response to Potassium Application
Hong Hu 土壤圈(英文版) 2004
Other claims from this paper (12)
- Intervention effect NPK significantly affected rice grain yield relative to NP.
- Intervention effect NPK significantly affected nutrient harvest index relative to NP.
- Mechanism Potassium was inferred to improve transfer of N and P from vegetative tissue to panicles.
- Intervention effect Rice N and P use efficiencies did not respond strongly to potassium.
- Intervention effect Rice K use efficiency decreased significantly with potassium application.
- Observation Total K uptake increased.
- Observation Varieties differed significantly in nutrient uptake and use efficiency.
- Mechanism Non-exchangeable soil K was identified as an important source for rice.
- Intervention effect Potassium application caused annual decline in available soil K.
- Intervention effect Potassium application increased non-exchangeable soil K.
- Recommendation The authors concluded that 100 kg ha-1 K per season was insufficient to match K output.
- Recommendation Efficient rice K management should use a K input/output balance.
