Abstract:
A process for forming an agglomerate for use as a soil conditioning agent, the process comprising:preparing a preagglomerate containing a water-soluble binder and a particulate calcium source selected from the group consisting of limestone, dolomitic limestone, gypsum, hydrated lime and mixtures thereof, the particulate calcium source having a particle size distribution such that less than about 1% by weight of the particulate calcium source is +20 mesh, less than about 10% by weight of the particulate calcium source is âˆ’20 +100 mesh and at least about 90% by weight of the particulate calcium source is âˆ’250 mesh Tyler Standard Sieve Series; and pelletizing the preagglomerate to form the agglomerate, the proportion of the particulate calcium source in the preagglomerate being sufficient such that the agglomerate comprises at least about 15% by weight of the particulate calcium source.
