Long Term Experiment Rostock: Phosphorus fertilization strategies

This data set contains detailed information on the management and evaluation of the long-term field trial in Rostock. It was established in autumn 1998 at the experimental station of the University of Rostock. The experimental station is located in Northern Germany in a maritime-influenced area about 15 km south of the Baltic Sea shore (54°3′41.47″N; 12°5′5.59″E). The average annual temperature is 8.1 °C and the mean annual precipitation is about 600 mm. The soil texture is loamy sand containing 1.1% Corg and the soil type is a Stagnic Cambisol according to the World Reference Base for Soil Resources. The initial double-lactate-soluble P content (DL-P) of 42.2 mg P kg−1 soil indicated a suboptimal P supply according to the soil P classification of the German federal state of
MV. The field trial was arranged as randomized split-plot design with four replications with organic fertilizers as main plots and inorganic fertilizer as subplots. The combination of organic and inorganic P supply resulted into nine fertilizer treatments as follows: control (no P), TripleSuperphosphate (TSP), biomass ash (ash), cattle manure (manure), biowaste compost (compost), and the combined applications manure + TSP, manure + ash, compost + TSP, and compost + ash. The plot size of each fertilizer treatment was 120 m².
