摘要
Inositol phosphate is at least equal to KH2PO4 as a source of P for the growth of lupins in sand but a much poorer source in soil. RNA and glycerophosphate were excellent sources of P for lupin growth in a P-fixing soil. Soil and root phosphatase activity were not altered by amendment of soils with either inorganic- or organic-P. The difference in availability of differing P-sources is related to their solubility in soils rather than susceptibility to phosphatases.
