ABSTRACT Soil phosphorus tests offer a potentially powerful tool for land
24
managers trying to predict the areas which will contribute diffuse
25
losses of phosphorus (P) to surface water bodies through the overland
26
flow vector – but do they work? We address this question at a range of

scales, from patch (
