ABSTRACT Background The controlled uptake long‐term ammonium nutrition (CULTAN) fertilization technique consists of injecting a concentrated solution into the soil and aims to positively impact crop physiology N use efficiency. Aims This study assesses whether CULTAN can contribute lower leaching while maintaining yields in temperate regions with an annual precipitation around 1000 mm or higher. Methods We analyzed 12‐year lysimeter experiment two consecutive 6‐crop rotations 3‐year field winter wheat maize Switzerland. was compared conventional surface application nitrate fertilizer (ConvF). Results achieved at least similar ConvF both studies had 38% yield‐scaled lysimeters. In studies, displayed higher nitrogen recovery efficiency (NRE) ConvF, increase ranging from 8% 17% depending on type, although statistical significance only found for study. NRE were weakly correlated, indicating that other pathways are affected system. Finally, we suggest timing placement injection need be better adapted plant pedoclimatic conditions optimal nutrient yields. Conclusion areas high concentration groundwater, effective strategy complementing loss reduction measures.

The individual nitrogen (N) contribution from above-ground plant residue (AGRP) and total below-ground residuals (BGRT) to a subsequent wheat crop remains poorly explored. need understand this dynamic is crucial for optimizing yield soil nutrient management. This study aimed discern the N contributions AGRP BGRT succeeding implications of various grain legume residues on these contributions. A four-year field consisting two 2-year legume–cereal cropping sequences was conducted in Saskatoon, SK, Canada. legumes were chickpea, faba bean, lentil, pea, with spring grown as reference 2014 2016. Each plot split into quadrants one quadrant receiving 15N-urea other three non-labeled (natural abundance, NA) urea pulse phase. After harvest, 15N-AGRP swapped NA-AGRP when returned field, resulting sub-plots 15N-AGRP/NA-BGRT NA-AGRP/15N-BGRT combinations. In 2015 2017 all plots planted fertilized based mineral measurements target yields. One NA received during cereal phase track fate fertilizer versus N. Grain species did not affect seed crop. However, lentil pea required less than residues. Over five tested residues, (roots, rhizodeposits, residual fertilizer, soil) largest source, accounting 70–91% uptake, which surpassed combination (1–11% uptake) (5–21% uptake). Among BGR components, main contributor wheat. recovery rates below 9% AGRP, 18% BGRT, 26% Below-ground residue, particularly soil, plays pivotal role regulating supply crop, overshadowing AGR fertilizer. research underscores significance BGR, especially management crops. Recognizing dynamics can help tailor strategies optimize

Nitrogen dioxide (NO2) impacts climate, air quality, soil nitrogen fixation, and crop production, yet its transboundary remain unclear. This study combines 15 global datasets to assess nitrogen’s on yields health. We use machine learning develop yield prediction models for major grain crops (maize, rice, soybean, wheat) affected by NO2. Our findings indicate stable fixation in China from 2015 2020, although overgrazing deforestation may cause declines. Increasing total content 0.62–2.1 g/kg can reduce NO2 10–30%. research indicates that the current agricultural environments (58.5–94.2%) have already exceeded concentration range tolerate, particularly regions near northern urban clusters. highlights need regional interventions, such as precision fertilizer management, enhance both yields. Scenario analysis suggests control boost maize rice a greener context, while increasing improves wheat soybean provides solution advancing sustainable agriculture linking cycle management with improved environmental sustainability.

In the Yaqui Valley, Mexico, current and estimated annual growth rate of durum wheat (Triticum turgidum L. subsp. durum) yield is insufficient to satisfy food demand that world will be facing by 2050. Furthermore, besides high doses fertilizers applied in this region, nitrogen-use efficiency (NUE) remains low (<34.4%). A sustainable strategy reduce use increase crop quality native plant growth-promoting bacteria as microbial inoculants. This study was performed under field conditions during one agricultural season Mexico. It aimed quantify impact inoculation a bacterial consortium (BC) composed Bacillus cabrialesii TE3T, Priestia megaterium TRQ8, paralicheniformis TRQ65 on grain yield, quality, NUE (measured through 15N-isotopic techniques) at different stages development variety CIRNO C2008 three urea (0, 120, 240 kg N ha−1) fractionated 30%, 60%, 10%. Results showed were highly affected doses, while BC had lower these parameters. Nevertheless, positive effects early growth, height (+1.6 cm), root depth (+11.9 spikes per square meter (+25 m−2). Moreover, addition improved acquisition plants, stages, compared uninoculated treatments. Finally, our results indicated reducing dose from ha−1 120 (27.5% vs. 44.3%, respectively) crop. Hence, preliminary incorporation inoculants into requires simultaneous adequate management, order obtain desired effect productivity.
