Other claims from this paper (12)
- Association Potassium uptake requirements increased with crop yield.
- Observation Cereals needed 22 versus 41 kg K per ton of harvested organ in soybean.
- Observation Cereals removed 3.8 versus 15 kg K per ton of harvested organ in soybean.
- Association Within maize, potassium internal efficiency varied with potassium harvest index.
- Association Within wheat, potassium internal efficiency varied with potassium harvest index.
- Association Within soybean, potassium internal efficiency varied with potassium concentration in harvested product.
- Association Across species, potassium concentration in harvested product was related to protein and moisture content.
- Observation Cassava and sugarcane had potassium internal efficiency of 87.
- Observation Cereals, potatoes and alfalfa had potassium internal efficiency of 41−58.
- Observation Banana and oil-rich crops had potassium internal efficiency of 10–30 kg kg⁻¹ K.
- Association Net K removal increased with higher yield, KHI and residue removal.
- Recommendation The authors recommend K management account for yield level, crop choice and residue management.
