A method of treating animal manure solids comprises contacting the solids wi th a treatment composition comprising AlCl3.cndot.nH2O or Al(NO3)3.cndot.mH2O, or the residue of AlCl3.cndot.nH2O or Al(NO3)3.cndot.mH2O, to form a treated waste product, wherein n is from O to 10, and m is from 0 to 12. The treatment amount can be effective to reduce phosphorus solubility in the manure; reduce phosphorus runoff and/or phosphorus leachin g from fields fertilized with manure; inhibit ammonia volatilization from the manur e; flocculate solids in the manure; reduce pathogens in the manure; increase the nitrogen content in the manure; and/or reduce acid rain and PM-10s associated with the manure.
