Rock solid low drying polyer urea
WebPolymer-Coated Urea (90 Day Release) $ 2,050.00 /t - Ex-Store Polymer-Coated Urea is a standard urea granule encapsulated in a biodegradable polymer coating. The polymer coating protects the urea from volatalisation and leaching losses whilst prolonging the nitrogen release period to better suit crop and pasture requirements.
