A method of treating liquid animal manure comprising contacting a manure slurry with a treatment composition comprising a treatment effective amount of AlCl3.nH2O or Al(NO3)3.mH2O, or the residue of AlCl3.nH2O or Al(NO3)3.mH2O, to form a resulting slurry, wherein n is from 0 to 10, and m is from 0 to 12. The treatment effective amount is effective to reduce phosphorus solubility, reduce phosphorus runoff and/or phosphorus leaching from fields fertilized with manure; inhibit ammonia volatilization; flocculate solids; reduce pathogens; increase the nitrogen content; and/or reduce acid rain and PM-10s associated with the manure.
