Slow-release fertilizers. Determination of the release of the nutrients. Method for coated fertilizers1 Scope This document specifies a method for the determination of the slow release properties of nutrients from coated fertilizers. pH dependent hydrolysis and degradation by biological or microbial mechanisms are excluded. The specified method is only applicable to products releasing any nutrients by means of a non biological process (i. e. those where the nutrients are released by a physical mechanism). Microbial attack on the coating (e. g. sulfur
