Aridity creates global thresholds in soil nitrogen retention and availability

Global Change Biology, Journal Year: 2023, Volume and Issue: 30(1)

Published: Nov. 9, 2023

Abstract Identifying tipping points in the relationship between aridity and gross nitrogen (N) cycling rates could show critical vulnerabilities of terrestrial ecosystems to climate change. Yet, global pattern N response across remains unknown. Here, we collected 14,144 observations from 451 15 N‐labeled studies used segmented regression identify threshold responses soil process‐related variables index (AI), which decreases as increases. We found on a scale that increasing reduced nitrate consumption but increased nitrification capacity, mainly due microbial biomass carbon (MBC) (MBN) pH. Threshold production retention was observed ecosystems. In croplands, extractable were inhibited with below AI ~0.8–0.9 ammonia‐oxidizing archaea bacteria, while opposite favored above this threshold. grasslands, mineralization immobilization decreased ~0.5 MBN, true forests, stimulated ~1.0 C/N ratio, ammonium ~1.3 total MBC/MBN ratio. Soil dissimilatory reduction globally forests when ~1.4 passed. Overall, suggest any projected increase change is likely reduce plant availability arid regions enhancing it humid regions, affecting provision ecosystem services functions.

Effectiveness of N Fertilizers with Nitrification Inhibitors on Winter Barley Nutrition and Yield

Sustainability, Journal Year: 2025, Volume and Issue: 17(6), P. 2610 - 2610

Published: March 16, 2025

Excessive N loss through leaching and volatilization is a major concern in modern agriculture, reducing use efficiency, groundwater contamination, environmental degradation. To address these issues, this research evaluates the impact of fertilizers containing nitrification inhibitors (NIs), which restrict conversion ammonium (NH4+) into nitrate (NO3−), thereby enhancing retention soil. This study examines effects different fertilizer applications on yield nutrient dynamics winter barley (Hordeum vulgare L.) Field experiments were conducted to compare one-time split application granular ENSIN (with NIs) DASA (without dynamics. The highest grain was observed with single (8.35 Mg.hm−2), followed by divided (7.97 both significantly outperforming control (no N). most efficient recorded for application, yielding 27.4 kg per applied N. Agrochemical analyses assess soil NH4+ NO3− content throughout vegetation period, lysimetric methods used determine losses. results highlight potential NIs improve uptake reduce loss, enhance sustainable production. Through optimizing strategies, contributes development more agricultural practices that crop while minimizing impacts, particularly runoff contamination.

Accelerated soil nitrogen (N) loss in young Chinese fir plantation compared to natural regeneration during initial warming years

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

Aims To assess how +5 °C soil warming affects nitrogen (N) dynamics in early-stage subtropical forests, we compared Chinese fir plantations and natural regeneration. The hypothesis was that accelerates N mineralization nitrification, increasing risks of leaching gaseous losses where sapling uptake is limited. Methods A experiment conducted China using buried heating cables (+5°C), incorporating treatments (Cunninghamia lanceolata) plantation Results Warming significantly increased annual net nitrification (except August) regeneration during January. In plantations, elevated DON, NO₃^--N, NH₄⁺-N surface (0-10 cm), as well NO₃^--N throughout the 0-60 cm profile, particularly contrast, decreased August. also concentrations leachate N₂O emissions across both plots. abundance functional genes related to cycling declined under warming, although maintained higher levels denitrification (narG, nirK, nosZ) N-fixation gene (nifH) plantations. Enrichment δ¹⁵N N-rich plant organs further reflected enhanced transformation warming. Conclusion induced a more open cycle with greater than early years. This highlights importance forest management value near-natural practices climate change.
