Abstract Aims Perennial forages in rotation with annual crops can improve agricultural resilience by increasing soil organic carbon. However, how nitrogen (N) sources interact diversity to influence nitrous oxide (N 2 O) emissions is not well understood. Methods During three snow-free seasons, N O emissions, crop yields, and ancillary variables were measured at experimental sites contrasting textures (silty clay sandy loam) eastern Canada. Using a split-plot design, we compared corn ( Zea mays L.)-soybean Glycine max [L.] Merr.)-corn mixed perennial grass sward receiving via: i) mineral fertilizer (MIN), ii) liquid dairy manure (LDM), iii) inclusion of alfalfa Medicago sativa L.) the no additional (LEG).

Abstract Europe’s nitrogen (N) crisis demands innovative food systems solutions to improve N cycling. This study modelled the potential of different diets and circular fertilization strategies enhance system use efficiency (NUE), reduce surplus, minimize reliance on synthetic fertilizers. Results show that circularity helps NUE total losses but does not consistently surplus per ha. Synthetic fertilizer could be reduced by 95% if healthy were consumed in systems, increasing from current 0.17 0.53. The reduction led increased manure showed considerable trade-offs with land greenhouse gas emissions (GHGe). In contrast, which vegan lowest GHGe a relatively high (~ 0.3). emphasizes importance considering synergies between environmental impacts when redesigning systems.

This article presents the current state of biogas (biomethane) production technology with an example using cow manure from perspective photofermentation efficiency. In specialist farms, there is a problem waste management in form manure; analyses were carried out on photocatalysis process order to be able effectively produce biomethane based monosubstrate solutions (manure). Cow was tested for its elemental composition determine suitability this raw material production. The compared A, which stored 1 week (fresh sample, wet), and B, month (old dry). A values as follows: N: 3.18% 3.34%; P: 0.403% 0.492%; K: 1.267% 2.336%; Na: 0.362% 0.714%; Ca: 0.705% 0.788%; Mg: 0.737% 0.907%. quality produced atmospheric conditions (material B) assessed. An increase CH4 observed temperature. For at temperature 22.5 °C, it range 11–14%; 25.5 approx. 35%. despite small amounts (from 0% 2%), tendency also observed. At 22.4 0–1%, 25.4 about 2%. novelty development innovative method manure, indicating industry.
