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 comprising CaO or Ca(OH).sub.2, the particulate calcium source including a material selected from the group consisting of cement kiln dust, lime kiln dust, manure ash and mixtures thereof, the combined concentration of CaO and other calcium-containing compounds having the potential to be hydrated in the preagglomerate being no greater than about 10% by weight;pelletizing the preagglomerate to form the agglomerate, the proportion of the particulate calcium source in the preagglomerate being sufficient such that the agglomerate contains at least about 15% by weight of the particulate calcium source; anddrying the agglomerate, the drying being controlled such that dried agglomerates having a size ranging from -7 to +8 Tyler Standard Sieve Series exhibit an average green crush strength of at least about 2 pounds.
