USE OF UREA-FORMALDEHYDE FERTILIZERS WHEN SEEDING ON SUBSOIL HIGHWAY SLOPES

PREVIOUS INVESTIGATIONS ESTABLISHED THE SUPERIORITY OF UREA--FORMALDEHYDE TO OTHER COMMERCIAL CHEMICAL FERTILIZERS IN SLOWLY RELEASING NITROGEN OVER THE ENTIRE GROWNG SEASON, WHICH SHOULD PROVE ADVANTAGEOUS WHEN SEEDING ON SUBSOILS. COMPARATIVE TESTS WERE RUN WITH THIS AND OTHER CHEMICALS IN UNIFORM AMOUNTS OF 100 LB NITROGEN PER ACRE. IN EVERY CASE THE CHEMICAL FERTILIZERS PROVED SUPERIOR. TWO EXPLANATIONS ARE ADVANCED FOR THIS: (1) UREA--FORMALDEHYDE REQUIRES BACTERIA TO BREAK IT DOWN. AS THESE CUTS WERE FRESHLY MADE IN SUBSOIL, THEY MAY NOT HAVE HAD SUFFICIENT BACTERIA. (2) BY THE TIME TERMPERATURES BECAME FAVORABLE FOR THE RELEASE OF NITROGEN, MOISTURE BECAME CRITICAL ON THE SLOPES, THUS PREVENTING PRODUCTION.
