Abstract
Nitrogen (N) fertilization and manure application are not traditional nutrient management practices for soybean production. Soybean is a legume plant and assumed to obtain adequate N through symbiotic N2-fixation. Also, since manure contains plant-available N in addition to other nutrients, it is preferentially used for com production to gain economic advantage from the manure-N.
