Development of transitional strategies for permanent cultivated areas and continuation of the digestate fertilization trial in full-grown silphia (Gärrest Umbruch)
Project
Project code: G2/N/18/04
Contract period: 01.01.2019
- 31.12.2021
Purpose of research: Applied research
Besides a long flowering period, the perennial crops Silphium perfoliatum (cup-plant) and Sida hermaphrodita also have further ecological advantages to annual crops. While cup-plant has been proven to be a competitive substrate for biogas plants, utilization as a solid fuel seems more advantageous for sida. For this reason cup-plant should be fertilized with digestates derived from biogas process to close nutrient cycles. The expected useful life of perennial crops is not unlimited and ends after about 10 to 20 years when a significant decrease in yield emerges. Several different strategies are thinkable for an elimination of the perennials and a return to the internal crop rotation of the farm.
