View larger version (16K): [in a new window]   Fig. 1. Relation of (a) relative beet yield, (b) relative sucrose yield, and (c) relative adjusted beet yield to preplant soil NO3–N. Tile-drained soils with high risk of leaching (furrow irrigation or winter rain higher than 470 mm—80% of the annual mean precipitation in the studied area) and rainfed locations in drought years (less than 350 mm year–1—less than 170 mm during spring) are excluded.

Tile drained soils with high risk of leaching (furrow irrigation or winter rain higher than 470 mm–triangles) and rainfed locations in drought years (less than 350 mm–circles) are excluded from the regressions.
