Summary

The chapter provides an introduction to manure characteristics with the focus on the physico-chemical properties of particles in the manure and its inorganic chemistry. Methods for determining particle size and charge as well as slurry rheology and density are presented, and typical values for animal manure are given. The important factor of pH chemistry in manure is introduced and it is shown how pH affects: (i) crystallisation of phosphorus and calcium, (ii) ammonia release, and (iii) adsorption of cations to the negatively charged particles.
