Would you have any concerns about blending pelletized calcitic lime together with granular MAP and ammonium sulfate?


While the blended product should not have any issues during storage, it could face problems once applied to the soil, due to potential ammonia volatilization (from the ammonium-N in both MAP and ammonium sulfate), as well as possible Ca-P precipitation (from Ca-lime and MAP), and gypsum precipitation (from Ca-lime and ammonium sulfate). Having said that, the concern would not be nearly as much as if it were the case of granulated product, since bulk blends allow for physical separation of granules upon application.
