%X Soil fertility patterns in the wheatgrowing areas of Victoria were examined. The three major patterns identified from the protein content of wheat delivered to 113 silos over the period 1946-74 showed a marked regional grouping encompassing the Wimmera (type 3), Western Mallee (type 2) and the Eastern Mallee, Northern and North-East Districts (type 1). Using 107 P x N wheat fertilizer experiments, four major patterns were identified. Only one of these (low P, nil N yield response) showed any regional grouping (with the Wimmera region); the other three (moderate P, moderate N; high P, small N ; and high P, nil N yield responses) occurred at random throughout the wheat belt. Possible reasons for these patterns and their implications are discussed.
