Plasma Treated Cattle Slurry Moderately Increases Cereal Yields

Plasma treatment offers an approach to enhance the nitrogen (N) content of livestock slurry and biogas digestate, thereby increasing efficacy organic fertilizers. This innovative method is used produce nitrogen-enriched fertilizer (NEO) containing a double concentration plant-available N. Over three years, we conducted comprehensive study in 14 spring wheat barley field trials Norway. The primary objective was assess compare cereal grain yield achieved by applying NEO other conventional utilized our research derived from unit developed Norwegian company N2 Applied. results indicated that 120 kg N ha−1 yielded same range grains as 95 mineral fertilizer. Moreover, combination untreated 55 Opti-NS NEO. Surprisingly 12 at sowing day 108 three-leaf stage led higher than spread two out experimental years. directly plants has shown no visible signs harm. Lastly, filtering resulted yields slurry. In conclusion, despite possessing content, utilizing 15–20% lower Nonetheless, 20–30% more native amount cattle it derived. However, have observed unexplained loss approximately 17% NEO, which does not translate into increased or productivity.
