Nitrogen (N) management is critical in sugar beet production. Too little nitrogen early in the growing season can reduce root yield, while too much later can reduce root quality. Growers are interested in increasing N use efficiency in sugar beet production by using alternative N management strategies, such as spring-applied N instead of fall-applied or applying enhanced efficiency nitrogen sources such as ESN (Environmentally Smart Nitrogen).
Too much spring-applied urea can reduce sugar beet production. Can ESN ease this problem? Outside the Midwest, sugar beets often need very large quantities of N. Loss of N through denitrification is one hypothesis as to why extra N is needed. Will the use of ESN preserve nitrogen for a longer period of time than urea?
