While carbon can be sequestered within products made with hemp fiber, there is little empirical evidence quantifying greenhouse gas contributions from the crop's production. Here we quantified fiber hemp's soil-to-atmosphere greenhouse gas fluxes and root production throughout the 2022 and 2023 growing seasons in central Kentucky and compared them to those of corn cultivated under similar conditions. Daily gas fluxes were measured from the plots throughout the growing season, accompanied by monthly soil sampling (0–10 cm) and root sampling (0–30 cm) at crop harvest. For both years, hemp and corn plots emitted similar cumulative amounts of carbon dioxide warming equivalents (2.1 ± 0.2 Mg ha⁻¹). Nitrous oxide emissions and methane uptake were significantly greater in corn in 2022 but were similar in 2023. Soil permanganate oxidizable carbon for each crop was similar at all time points measured, though there was a seasonal trend, suggesting comparable labile soil organic matter contributions to gas emissions. End of season in-row root measurements in 2022 and 2023 revealed that corn plots contained up to 3.5 times more root biomass than hemp at both the 0- to 10- and 10- to 30-cm depth profiles. Under these cultivation conditions, fiber hemp released similar amounts of greenhouse gas equivalents while storing significantly less carbon belowground in roots than corn, calling into question the idea that hemp cultivation is likely to improve the short-term environmental sustainability of the cropping system.</p>","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"9 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70407","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interseeding alfalfa with sainfoin (<i>Onobrychis viciifolia</i>), a tannin-rich legume known for its anti-bloating properties and environmental benefits, has emerged as a potential solution. A 2021–2023 field trial evaluated the impact of interseeding alfalfa with sainfoin on forage mass, nutritive value, and condensed tannin (CT) concentration near Cedar City, UT. Two treatments, alfalfa monoculture (Mono) and alfalfa–sainfoin mixture (Mixed), were established in 2021. In the establishment year, the mixed system showed a roughly 10% forage mass advantage compared to Mono, though no consistent difference was observed in subsequent years. Forage nutritive value parameters were primarily influenced by cutting time and seasonal variation rather than treatment. Despite limited treatment differences, crude protein, relative feed value, relative forage quality, and total digestible nutrients values in both systems consistently met USDA criteria for “supreme” quality hay. CT concentrations varied significantly by treatment, year, and cutting. Notably, in 2022, the mixed system showed substantially higher CT concentrations during early cuttings compared to the monoculture alfalfa (0.823% vs. 0.20% in the first cutting and 0.47% vs. 0.25% in the second cutting), indicating that sainfoin can meaningfully enhance forage CT concentration when well-established, but not consistently. These findings suggest that interseeding sainfoin may offer early-season benefits in both forage mass and bloat-mitigating potential, though year-to-year variability and cutting stage may influence overall forage value.</p>","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"9 3","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70403","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sampling of spring export at two locations characterized sediment discharge. Sediment characterization, including particle size, nutrients, and minor and trace elements, was used in an unmixing model to estimate sediment source contributions. Streambank erosion sources and cave bed and bank sources were the dominant sediments discharging from the cave, although variations in relative proportions were associated with differences in sediment source target values.

The experiment was conducted at Hawassa, Belela, and Bilate in Sidama and South Ethiopia during the 2022 and 2023 growing seasons. The treatment consisted of four cassava varieties (Hawassa 04, Qulle, Chichu, and Kello) and three levels of nitrogen fertilizer (0, 50, and 100 kg N ha⁻¹). The experiment was arranged in a Randomized Complete Block Design with a 4 × 3 factorial arrangement and three replications at each location. Results showed significant improvements in growth traits and root yield parameters due to nitrogen application and varietal difference. Among the tested varieties, Chichu consistently produced the higher yield across locations. The application of 100 kg ha⁻¹ nitrogen at the Bilate location produced the greatest root yield of Chichu by 90.61% increment over unfertilized plot of Qulle. For Hawassa and Belela, Chichu with 50 and 100 kg ha⁻¹ N applications can be recommended for cassava yield, respectively. The observed variation among varieties and locations highlights the genetic differences and the influence of environmental conditions on cassava performance.
