Project started: 2009


Location:

Brandenburg, East Germany, Polish border


Field area: 1 ha


Climate & soil condition

very dry climate, very nutrient-poor soils



Applications:

  • Control:
    pure Cambisol
  • Compost:
    6.5t Compost (~32.5 Mg ha-1)
  • Biochar-Compost 5:
    6.5t Compost +0.9t Biochar (~5Mg ha-1)
  • Biochar-Compost 10:
    6.5t Compost +1.8t Biochar (~10Mg ha-1)
  • Biochar-Compost 20:
    6.5t Compost +3.6t Biochar (~20Mg ha-1)

Experimental setup:

  • four treatments with biochar/compost
  • constant water balance measurements
  • over four vegetation periods

Results:

  • the yield could be increased
  • C sink (20 Mg ha-1)
  • N losses could be limited
  • water storage could be increased
