Summary
Soil samples, roots and shoots were collected from barley crops at three locations which had received different combinations of N and P for 10 years, and from long-term fertilizer experiments on barley in a sandy soil and on barley and wheat in a loamy soil.
Soils were analysed for available P by an anion exchange resin procedure, roots were examined for intensity of VAM infection, and shoots wee analysed for N and P.
Vesicualr-arbuscular mycorrhizal infection was found at all locations. It was most abundant at the three locations with least soil-P and lightest at the two locations high in soil-P. Within loocations an inverse relation was found between soil-P level and intensity of infection. Infection was also intensity. by increasing N-fertilizer. Spore counts from selected samples correlated well with infection intensity. Shoot-P did not differ significantly between treatments in spite of significant differences in soil-P. This points to the significance of vesicular-arbuscular mycorrhiza: a lower soil-P level accompanied by a higher infection intensity seem to counterbalance each other to a certain extent.
