The response of broad bean ( Vicia faba L.) and corn ( Zea mays L.) to CULTAN fertilization was compared. Roots of broad bean turned black and were severely damaged by CULTAN fertilization, whereas corn roots were not affected. Consequently, dry matter production of roots and shoots of broad bean was significantly reduced. CULTAN fertilization caused a soil pH increase which may be attributed to hydrolysis of urea applied during CULTAN fertilization. It is assumed that the occurrence of high NH 3 concentration in soil due to CULTAN fertilization may be toxic to broad bean but not to corn.
