Abstract The study aimed to measure soil-atmosphere N 2 O fluxes and their controlling factors, as well NH 3 emissions yields for two soils (silt loam clay loam) in three management systems over years under subsequent wheat maize cultivation. were characterized follows: (1) cash crop (C) with mineral fertilizer conventional tillage; (2) livestock (L) biogas residue fertilization its incorporation prior sowing reduced (3) climate optimized (O) minimum tillage, 8-year rotation, fertilization, without soil or by strip-tillage seeding silt soil. Stable isotope ratios of determined identify processes. Within the organically fertilized treatments, cumulative highest O-system treatments both sites (4.0 9.4 kg ha − 1 a ), i.e. more than twice high L-system (1.5 3.1 ). Below root-strip till application did not enhance fluxes. Fluxes (1.1 ) different from those organic fertilization. Isotopic values emitted revealed that bacterial denitrification dominated most peak flux events, while O/(N + O) ratio was mostly between 0.1 0.5. It can be concluded that, contrary intention lower greenhouse gas management, occurred digestate maize. With respect fluxes, we could confirm growing crops late before induces beneficial aspects including stable structure resource conservation, are thus potentially counteracted increased emissions.

Pastures serve as the primary source of grass and forage plants for grazing livestock, requiring adequate nutrient input to sustain growth soil fertility. Slurry from livestock industry is widely utilized a sustainable cost-effective alternative chemical fertilizers. Microorganisms within slurry–pasture system are essential breaking down organic matter, facilitating cycling, improving health. However, mismanagement or inefficient microbial decomposition can lead significant issues, such leaching into water bodies, causing eutrophication, antimicrobial resistance, reduced availability in pastures, which, turn, may negatively impact productivity. Thus, this paper investigates composition benefits slurry pasture management, highlights roles evaluates regulatory frameworks Ireland Europe. Additionally, it examines environmental risks associated with improper application, providing insights support management practices.

Effective nitrogen (N) management is essential for minimizing fertilizer nutrient losses and maximizing N use efficiency. This study, conducted over two years on permanent grassland sites in Schleswig-Holstein, Germany, explored the effects of urea treatment with a urease inhibitor digestate acidification N-cycling yield performance temperate maritime context. Micro plots within these grasslands received varying rates via acidified (with sulphuric acid) or non-acidified (biogas residues), treated with- without (N-(n-butyl) thiophosphoric triamide) calcium ammonium nitrate. Parameters measured included dry matter accumulations, NH3 volatilization, N2O emissions, NO3--N leaching, methane (CH4), total greenhouse gas (GHG) emissions from soils. The findings demonstrated that consistently enhanced metabolizable energy (ME), yields (up to 47 %) apparent recovery (ANR). While concurrently reduced did not significantly affect (p> 0.05) (DM) yields, ANR, GHG emissions. Thus, stabilization could effectively mitigate environmental impact forage grass production while maintaining higher comparable yields. However, risks pollution swapping groundwater bodies may result input rates. Applying stabilized at 120 kg mineral ha−1 rate offers practical approach, yielding appreciable ME losses.

Abstract Ammonia (NH 3 ) loss following manure application is an environmental concern and N for crop production. Manure injection typically reduces NH compared to surface without incorporation but increases emissions of nitrous oxide (N 2 O), which a potent greenhouse gas. Synchronizing in spring with cover (CC) growth may increase recovery reduce O applying later the absence growing crops. We two methods: shallow‐disk (IM) or banding (BM) annual ryegrass ( Lolium multiflorum L.) red clover Trifolium pratense CC at times: early on (EARLY) late terminated (LATE). The randomized split‐plot block experiment was conducted Rock Springs, PA, during 2021–2022. After application, we measured 72 h throughout season. Aboveground biomass, N, C:N ratio; pre‐sidedress soil nitrate; corn Zea mays stalk silage yield were assessed. Averaged across times, BM, IM reduced cumulative loss, increased resulted 13% greater yield‐scaled O. Compared BM LATE, EARLY by 43%, emission 50%, decreased 11%. When 84%, 55%, similar. Injecting CCs offers strategy reducing detrimental maintaining yield.
