Other claims from this paper (18)
- Intervention effect Sodium fertilizer increased sugar beet sugar yield.
- Association Sodium and potassium fertilizers had a large negative interaction on sugar beet sugar yield.
- Intervention effect Magnesium fertilizer increased sugar beet sugar yield.
- Intervention effect A larger nitrogen dressing decreased sugar beet sugar yield.
- Intervention effect Sodium fertilizer affected the concentration of impurities in sugar beet root juice at harvest.
- Intervention effect Potassium fertilizer affected the concentration of impurities in sugar beet root juice at harvest.
- Intervention effect Nitrogen fertilizers affected the concentration of impurities in sugar beet root juice at harvest.
- Intervention effect Sodium fertilizer greatly increased sodium in the dry matter of sugar beet tops.
- Intervention effect Sodium fertilizer decreased potassium concentration in the dry matter of sugar beet tops.
- Intervention effect Sodium fertilizer changed the composition of sugar beet roots little.
- Intervention effect Potassium dressings slightly increased potassium in sugar beet tops.
- Intervention effect Potassium dressings did not affect the root composition of sugar beet.
- Intervention effect Exchangeable sodium in the top soil of sodium-fertilized plots decreased rapidly early in the season.
- Intervention effect Exchangeable sodium in the top soil of sodium-fertilized plots increased again from August.
- Intervention effect Soil potassium decreased throughout the season on plots where potassium was applied.
- Intervention effect Soil potassium did not change on plots without potassium fertilizer.
- Mechanism The decline of soil potassium under potassium fertilization is explained by fixation and release from non-exchangeable forms.
- Mechanism On this soil, sodium affects sugar beet yield only as a replacement for potassium.
