Phosphorus (P) fertilization effects on dry matter and nutrient content of the legume catch crop Serradella in a pot experiment with problematic soils

We identified problematic arable soils in northeastern Germany, which fix P and thus, insufficiently supply P to field crops. To overcome the P shortage we investigated the influence of the legume catch crop Serradella on the P supply and P release in a pot experiment with these soils. Three fertilization intensities (without phosphorus fertilization (P0), 50 kg triple superphosphate (TSP) per hectare (P50) and 100 kg TSP per hectare (P100)) were tested with and without Serradella. Two samplings were performed during the experimental period: an intermediate harvest four weeks after sowing and a harvest eight weeks after sowing. Dry matter and nutrient content of Serradella werde determined on both samplings.
