Phosphorus status of agricultural soils in Germany
The present report gives a general overview on the phosphorus (P) status of agricultural soils in Germany and highlights the use of manure as a P source.
An efficient use of phosphorus (P) is important for a sustainable agriculture, since P is a non-renewable limited resource and essential for plant production. Furthermore, lower P inputs help to reduce P losses from field into waters bodies, were P causes algae blooms and oxygen depletion.
The two German federal states Mecklenburg-Vorpommern (M-V) and Schleswig-Holstein (S-H) which border on the Baltic Sea are characterized by declining P contents in the soils. In S-H and M-V more than 90 % of the arable land has optimal or suboptimal P concentrations in soil. This will lead to low P inputs into the Baltic Sea in the future. However, in order to prevent negative yield effects an adequate P supply of soils is recommended. Closing the P cycle on farms is still an important objective for the German agriculture.
This report on the P status in Germany was prepared as part of work package 4 on manure standards in the project Baltic Manure.
