L28 - Effect of N-fertilization by different organic fertilization - Methau
This experiment has been added by the GLTEN Curators using existing published sources.
- Objective
- To study effects of long-term differentiated mineral-organic fertilization in a crop rotation on the yield, nutrient balance, and soil properties.
- Description
- One of three experiments established in 1966 at three locations across Germany.
