The studies were carried out to evaluate the utilization of nitrogen applied to the soil with putrified sewage water by fodder maize and grasses. Irrigation with sewage water containing considerable quantities of nitrogen caused a little increase of total and easy to hydrolize nitrogen content in corn crop, however content of those elements in grasses decreased.
