These grains are fragments of other rocks or minerals, bound together by cement. Depending on the variety of sandstone, the grains may range from poorly sorted to well sorted. Likewise, the grains may be rounded or angular.Glauconite, a major component of greensand, is a common source of potassium (K +) in plant fertilizers and is also used to adjust soil pH. It is used for soil conditioning in both organic and non-organic farming, whether as an unprocessed material (mixed in adequate proportions) or as a feedstock in the synthesis of commercial fertilizer powders.
