Efficient utilization of various phosphorus (P) sources for producing optimum yields in P‐deficient conditions requires knowledge of best management under changing weather conditions. In this study, barley ( Hordeum vulgare ) was grown in an extremely P‐deficient soil with variable moisture conditions. During a wet growing period, utilization of P from dairy cow manure ( DCM ), fox manure ( FM ) and meat and bone meal ( MBM ) was compared with the utilization of P from superphosphate ( SP ) with concomitant effects on grain yield and quality. High P application rates were necessary to compensate for severe yield losses due to waterlogging. Only 7 kg P/ha was required for optimum yield in less waterlogged conditions, while 43 kg P/ha was needed in waterlogged conditions. In both moisture conditions, broadcast DCM ‐P increased grain yield similar to banded SP ‐P, although P acquisition was lower in early growth stages. FM ‐P and MBM ‐P were less efficiently utilized. Waterlogging also depressed yield quality when P was applied. Extreme rainfall events are predicted to become more frequent at northern latitudes. As an alternative to higher P fertilizer rates, improving soil drainage could be a favourable, long‐term measure for better utilization of applied P and soil P resources, even at very low soil P status.
