Farmers were interested in the potential economic and conservation benefits of soil health, but current soil health report outputs are difficult to understand and put in practice. Farmers wanted clear management guidance that is tailored to their specific edaphic context. While they expressed ambivalence about specific indicators, they wanted to understand a full picture of their soil health.

Implementing bioreactors at larger areas (e.g., &gt; 20 ha vs. &lt; 10 ha) could facilitate treatment of relatively greater flow volumes, and thus greater nutrient loads, even if a notable portion of the annual flow bypasses treatment. For example, a hypothetical bioreactor design flow rate of approximately 1.8 L/s resulted in mean treatment of 40,600 versus 15,300 m³/year at large versus small sites assessed here. This flow rate corresponded to 5% versus 50% non-exceedance probabilities, respectively, meaning the design for the large drainage area would not meet current design expectations of 15%.

RhizoSorb was applied once at the beginning of the experiment at three rates followed by 3 years of poultry litter applied at three rates in split-plots of each RhizoSorb rate. Poultry litter applications increased the WEP of soil sampled in the fall of each year, with P concentration increasing as a function of litter application rate and years of application. RhizoSorb decreased WEP between 26% and 53% in the first and second year of the study.

Hurricane-affected cane samples were analyzed to quantify degradation and microbial activity. Marginal impacts on juice quality were observed immediately following the storm; however, these impacts did not persist across the season. Initial measurements showed a roughly 15% decrease in sugar content in storm-affected cane, with lower pH and elevated dextran content. Despite hurricane effects, the industry did not appear to have any major losses in productivity based on economic reporting and subsequent juice measurements taken at the end of the season. Regardless, the experimental techniques presented here for microbial degradation quantification represent potential opportunities for the industry to incorporate new modes of forecasting, monitoring, and mitigating losses attributable to microbial activity in damaged sugarcane.</p>","PeriodicalId":48502,"journal":{"name":"Agricultural & Environmental Letters","volume":"10 2","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/ael2.70035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145824496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As water scarcity intensifies, precision irrigation technologies, such as artificial intelligence (AI) with integrated ground-penetrating radar (AI-Radar), can be a promising solution for optimizing water use at the field scale in crop production systems. This on-farm trial evaluates the AI-Radar irrigation system compared to a conventional irrigation system (subsurface drip, SSDI) in central Kansas. Spatial analysis of the water deficit index (WDI) determined using high-resolution satellite imagery showed significantly reduced values of this index under AI-Radar–based irrigation (0.15–0.16) compared to SSDI (0.20–0.24; <i>p</i> &lt; 0.07) during critical tasseling to dough (VT–R4) growth stages. Lower WDI indicates more efficient spatial water distribution with minimal crop water stress. Addtionally, the AI-Radar system applied 23.5%–25.1% less irrigation water than the SSDI system while maintaining lower crop water stress. Therefore, this case study demonstrates that adopting AI-Radar–based irrigation could support groundwater conservation and regulatory compliance in the Southern Great Plains region.</p>","PeriodicalId":48502,"journal":{"name":"Agricultural & Environmental Letters","volume":"10 2","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/ael2.70047","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145845966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Vapor pressure deficit, not temperature per se, limits coffee photosynthesis under irrigation","authors":"Fábio M. DaMatta","doi":"10.1002/ael2.70050","DOIUrl":"10.1002/ael2.70050","url":null,"abstract":"&lt;p&gt;Coffee (&lt;i&gt;Coffea arabica&lt;/i&gt; and &lt;i&gt;Coffea canephora&lt;/i&gt;) is among the world's most valuable agricultural commodities. It is cultivated across tropical regions where rainfall, temperature, and irradiance strongly influence phenology, yield, and bean quality (DaMatta et al., &lt;span&gt;2025&lt;/span&gt;). However, coffee production is increasingly threatened by climate-related stresses, particularly heat waves and droughts, with models projecting substantial yield losses under future warming (DaMatta et al., &lt;span&gt;2018&lt;/span&gt;; Rahn et al., &lt;span&gt;2025&lt;/span&gt;). In response, irrigation has expanded steadily, especially in Brazil, the world's leading producer (Ronchi &amp; DaMatta, &lt;span&gt;2025&lt;/span&gt;).&lt;/p&gt;&lt;p&gt;Elevated air temperature has long been regarded as the main constraint to coffee growth under irrigation, mainly by affecting flower production and, particularly, photosynthesis-driven fruit filling (DaMatta &amp; Ramalho, &lt;span&gt;2006&lt;/span&gt;). This perception originates from an outdated notion, still widely cited in technical circles, that &lt;i&gt;C. arabica&lt;/i&gt; photosynthesis decreases by 10% for each 1°C rise above 24°C and ceases at 34°C (Nunes et al., &lt;span&gt;1968&lt;/span&gt;). Controlled experiments, however, show that both &lt;i&gt;C. arabica&lt;/i&gt; and &lt;i&gt;C. canephora&lt;/i&gt; maintain high photosynthetic rates up to 37°C (Dubberstein et al., &lt;span&gt;2020&lt;/span&gt;; Rodrigues et al., &lt;span&gt;2016&lt;/span&gt;), indicating that temperature alone cannot explain the reduction in carbon assimilation under warm conditions.&lt;/p&gt;&lt;p&gt;The true limiting factor is vapor pressure deficit (VPD), which increases exponentially with temperature and declining relative humidity (Kath et al., &lt;span&gt;2022&lt;/span&gt;). Elevated VPD enhances evaporative demand, triggering stomatal closure to reduce water loss. Although protective, this response restricts CO&lt;sub&gt;2&lt;/sub&gt; diffusion into the leaf and limits photosynthesis, the process underpinning 90%–95% of plant biomass accumulation (Khanna-Chopra, &lt;span&gt;2000&lt;/span&gt;). In coffee, stomatal conductance declines sharply with increasing VPD, especially during warm, dry afternoons, leading to strong depressions in photosynthesis even when soil water is adequate (DaMatta et al., &lt;span&gt;2025&lt;/span&gt;). Conversely, experimentally lowering VPD helps preserve stomatal aperture and photosynthesis (Batista et al., &lt;span&gt;2012&lt;/span&gt;). Collectively, these findings indicate that coffee photosynthesis is resilient to moderately high leaf temperatures and that carbon assimilation declines above ≈30°C mainly reflect VPD-induced stomatal limitation (DaMatta et al., &lt;span&gt;2025&lt;/span&gt;). Supporting this view, coffee yields correlate more strongly with VPD than with temperature or humidity, with productivity dropping sharply above ≈0.8 kPa—a threshold that, under projected global warming exceeding 2°C, will be surpassed frequently, jeopardizing yields across producing regions (Kath et al., &lt;span&gt;2022&lt;/span&gt;). Recognizing VPD as the principal constraint thus opens new avenues for adaptation: Bre","PeriodicalId":48502,"journal":{"name":"Agricultural & Environmental Letters","volume":"10 2","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://acsess.onlinelibrary.wiley.com/doi/epdf/10.1002/ael2.70050","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145739420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
