Activity Index of Urea-formaldehyde compounds and moulding powder

Abstract

The Urea-formaldehyde products exhibit distinctly different patterns of nitrogen availability involving low initial and more uniform response than the standard source of nitrogen. The overall efficiency of properly formulated uren-form product equals or excoeds that of conventional nitrogen fertilizers in respect of long season crops such as turf. The single application of uren-form may be made at higher levels than would be feasible with more soluble nitrogen sources.
