Odlingssystemet ”Strimsådd av ekologiska radodlade grödor i utvintrande mellangrödor”, som studerats detta projekt, innebär att man efter plöjning på sensommaren för rotogräsbekämpning sår olika ”frostkänsliga” mellangrödor augusti-september. Biomassan från mellangrödan vissnar ner eller fryser bort under vintern och får står kvar fältet till våren. På våren sås en ny huvudgröda mellangrödans växtrester ”såstrimmor” hackats fram sommarmellangrödan, d.v.s. huvudgrödan etableras ett ”strip-till-system”. Mellangrödornas effekt ogräsen hösten beror stor del mellangrödornas marktäckningsgrad. Mellangrödor med större marktäckningsgrad ger generellt bättre ogräskonkurrens jämfört har lägre martäckningsgrad.

The reformed Common Agricultural Policy of 2023-2027 aims to promote a more sustainable and fair agricultural system in the European Union. Among proposed measures, incentivized adoption cover crops soil during winter provides numerous benefits such as improved structure reduced nutrient leaching erosion. Despite this recognized importance, availability spatial data on is scarce. increasing field parcel declarations Union has not yet filled gap due its insufficient information content, limited public lack standardization at continental scale. At present, best available regionally aggregated survey data, which although indicative, hinders development spatially accurate studies. In work, we propose statistical model relating Sentinel-1 existence 100-m resolution over entirety United Kingdom estimate parameters using data.

In Ethiopia, using pesticides to manage pests in the growing of fruits and vegetables is a standard practice. Various classes have been approved combat pests, but majority those use now are outdated broad-spectrum insecticides with significant residual effects on crops freshly eaten vegetables. This review reveals that Ethiopia’s assessment pesticide level has lacking. According reviewed literature, often treated many countries levels. However, Ethiopia not adequately reported this issue. Furthermore, due lack knowledge regarding impact residues human health, Ethiopians frequently improperly control The consumers eat their unprocessed, without washing or cooking them first. To reduce risk for consumer safety battle health toxic chemicals humans, monitoring raising awareness about adverse humans urgently needed. Before they may be registered sold, as well environment must also undergo proper testing evaluation. New generations fewer side developed. By washing, peeling, canning, boiling before consumption, detrimental can minimized.

Emission of greenhouse gases from liquid animal manure (slurry) can be reduced if slurry is treated through anaerobic digestion. The effluent the reactor (digestate) utilized as a nutrient source for crop production applied in field. Physical and chemical properties digestate vary considerably due to large variation digester feedstock operation, these differences affect ammonia emission following field application. Generally, there scarcity literature assessing downstream effects digestion on field, different results have been reported. present work summarizes current knowledge after application digested systematic review. Furthermore, implications how data are interpreted evaluated with focus situation Denmark, where biogas industry rapidly expanding. potential pH dry matter between raw added was ALFAM2 model. Overall, no consistent difference emissions undigested observed data, likely opposing decreases increases pH. However, use high co-substrates digestates not representative Danish conditions, may contents. Predictions AFLAM2 model show that trend towards increasing contents coupled nearly universal elevated risk emission. Better empirical documentation urgently needed, especially high-viscosity digestate, along new methods mitigate land potential.

Harvesting a winter rye energy cover crop (Secale cereale L.) could help sustain growing food and demand, provide new revenue streams, enhance ecosystem services without inducing land-use change. A two-year field experiment with three planting methods N fertilization rates (0, 60, 120 kg ha−1) that produced >5.0 Mg ha−1 yr−1 of biomass was evaluated for (1) fresh anaerobically digested forage quality; (2) potential from renewable bioenergy, carbon markets, digestate feed protein; (3) greenhouse gas (GHG) offsets. We showed can be harvested as animals or to produce natural (RNG), the residue after digestion (digestate) still available protein concentrate. Anaerobically digesting improved quality indicators. Digestion significantly decreased acid- neutral-detergent fiber (ADF NDF) by 5.2% 17.8%, respectively, while increasing crude (CP) (33.6%), total digestible nutrients (TDN) (2.0%), relative value (RFV) (23.6%), net lactation (8.3%), maintenance (7.5%), gain (20.0%). Using market prices RNG, high feed, GHG mitigation, on-farm ranged USD 307 Mg−1 502 dry matter an average 402 Mg−1. However, there are substantial costs associated RNG does not represent profitability this system. Evaluation integrated system emissions were more than offset benefits yield in 60 treatment.
