P uptake and yields of winter wheat, sugarbeet and maize (fresh fodder) grown with NK on a leached chernozem soil were higher than when grown on a calcareous chernozem soil. Applied P was fixed in not readily available forms to a greater extent in the leached chernozem soil than in calcareous chernozem soil, indicating the need to apply P at a higher rate to leached chernozem soil than to calcareous chernozem soil to obtain similar yield increases.
