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
