The objectives of this study were therefore to evaluate three chemically precipitated biosol- ids and two types of meat and bone meal with regard to: 1) their effects as slow-release P fertilizers; 2) their sec- ond and third season effects on extractable soil P (POlsen and PAL); and 3) the three-year P balance in different soils.	cache/afs-7498.pdf	txt/afs-7498.txt
