Can Finnish White AS be used in no-till or conservation-till management?
Residue left on the soil surface in no-till and conservation-till systems can promote N loss from volatilization when urea and urea-containing fertilizers like UAN solution are broadcast and not incorporated into the soil. Ammonium sulfate is not susceptible to volatilization loss because its N is in the ammonium form. University studies have demonstrated that ammonium sulfate can be broadcast on the surface of no-till and conservation-till soils with very little risk of N loss due to volatilization.
