ABSTRACT:
This invention pertains to a fertilizer and a process for producing the same which incorporates flyash, which is a by-product from the coal fired utility industry, with an organic fertilizing component comprising manure. The flyash and manure are mixed with the resulting mixture compressed by passing the mixture through a roller press thereby forming a sheet and then fracturing the sheet into chips or other particulate form. The water content of the mixture is controlled in an effort to produce particulates having high dry strength.
