Luftreinhaltung im Interesse des Pflanzenbaus

Duckweed can efficiently produce protein-rich biomass on nutrient-rich waters, such as wastewater or liquid farmyard manure, while simultaneously binding nitrogen and phosphorus. This presents potential for modern circular economy systems.

Imports from abroad were incorporated into Switzerland’s farm-gate-budget-based agricultural nutrient budget calculation to expand it into a food-system budget. This allows assessment of self-sufficiency, nutrient use and circularity to be assessed in addition to nutrient surpluses.

With the passage of time, crop yield losses can occur on no-till farmland. Researchers from Agroscope and the Universities of Graz and Nevada demonstrated how subsoil compaction can lead to yield losses.
