Other claims from this paper (9)

Observation At BBCH16/17, plants were well nourished with macroelements.
Observation At BBCH16/17, plants were deficient in microelements, mainly iron and zinc.
Mechanism The authors attributed microelement deficiency to slightly acidic to neutral soil reaction.
Intervention effect No-tillage tended to reduce leaf macronutrient content at BBCH 39/40 versus conventional tillage.
Intervention effect Reduced tillage did not decrease sugar beet yield.
Intervention effect Cultivation treatment had no significant effect on molassegenic compounds in beet roots.
Intervention effect Alpha-amino nitrogen content tended to decrease versus traditional cultivation.
