Vorlag Effekte einer Schwefel- und Phosphor-Düngung auf Futterleguminosen auf einem Schwefel- und Phosphormangelstandort

Summary

In this study the effect of sulphate fertilization and rock phosphate fertilization on legumes in a grass clover mixture was investigated on a field under S and P limiting conditions. The results showed that S fertilization resulted in higher yield. Increment of yield came along with higher P uptake, but with decline in P concentration in the shoots. The results suggest that although P might have become a limiting factor, the plants have realized to meet their increased P demand in the case of higher growth rates. became a limiting factor. Independent of S fertilization level rock phosphate application didn’t show any effect.
