Description

Because Iowa soils were saturated frequently and some were flooded for various lengths of time, questions arise on whether fertilizer practices should be adjusted in 1994 for these situations. These questions deal with nitrogen fertilizer rates and time of application, potential changes in soil test values, and potential fallow syndrome on soils that were flooded.
