With the general quick growth and dense stand to shade soil surface, hemp produced for fiber, when established early, has the potential to compete with weed populations and prevent weed proliferation. The objectives of this study were to evaluate how a planting date continuum of fiber hemp impacted weed pressure under two growing scenarios, continuous hemp and weed competition or early season weed removal, to inform future research and provide production guidance to hemp producers. Pre-plant tillage and herbicide applications to establish fiber hemp in the present study resulted in plots that were generally weed-free. Data collected on weed biomass and species present supported that planting and harvest dates did not significantly impact weed pressure, and that weeds present were also biologically insignificant relative to the fresh fiber hemp yield measured. When planting fiber hemp, producers should focus on proper field location and preparation, timely planting, and correct seeding rates to mitigate weed pressures in the interim to post-emergence herbicide approvals.","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70090","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726849","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}

Simultaneously, the emergence of the circular bioeconomy introduces a framework emphasizing the sustainable utilization of renewable biological resources. This study explores a quantitative approach using bibliometric analysis of Web of Science datasets. The examination of 7863 scientific documents enabled the identification of significant scientific clusters, trend topics, factorial analysis, and thematic evolution from 1990 to 2024 related to the studied fields. The findings indicate that the most important link between the three investigated axes lies in managing natural resources such as soil and water, which are key components of agricultural productivity and are directly impacted by climate change. In this sense, the sustainable use of these resources is a significant factor in mitigating the effects of climate change while fostering resilience in agricultural food systems. Since 2016, scientific publications about the topics have increased significantly in the Global North and South. Based on the co-occurrence of keywords, five clusters with different levels of importance can be distinguished: (1) soil and water use efficiency, (2) productivity impacts, (3) management impacts, (4) biomass, and (5) climate change. These findings are significant since the major trending researched topics suggested will be those concerned with resource vulnerability, soil conservation and application of microorganisms, density dependence, and efficient use of resources. By synthesizing these findings, our study contributes to a comprehensive understanding of the current state of research, identifying potential gaps and areas for future exploration.","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70085","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717103","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}

Applying the correct rate, type, timing, and placement of fertilizers is essential for maximizing agricultural benefits and ensuring sustainable productivity. Addressing these issues is critical for promoting sustainable agricultural practices and improving food security. Therefore, the objective of the experiment was to identify the major yield-limiting soil nutrients for sorghum yield in northern Ethiopia. A randomized complete block design with three replications was used at each landscape positions. The nutrients evaluated in the study were nitrogen (N), phosphorus (P), sulfur (S), zinc (Zn), boron (B), and potassium (K). The treatment applied included control, recommended NP (RNP), NPSZnB, NPKSZnB, NPZnB, NPSB, NPSZn, 150% NPKSZnB, and 50% NPKSZnB. These treatments were implemented across each landscape position. The research findings indicated that the application of 150% All + K nutrients resulted in the highest grain and biomass yields across all landscape positions. When compared with the RNP treatment, there was no significant difference in yield at all slopes. Omitting S, Zn, B, and K did not significantly affect the grain and biomass yields, suggesting that these nutrients are not yield limiting for sorghum in the study area. These findings suggest that prioritizing N- and P-containing nutrients is essential for maximizing sorghum yield, thus contributing to sustainable agricultural practices and improved food security in the region.","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70084","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717169","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}

This study investigated the potato response to P and S applications regarding yield, quality, and fertilizer use efficiency. The three P (0, 56, and 112 kg P ha−1) rates were applied along with five S rates (0, 45, 90, 135, and 180 kg S ha−1) at two sites with split-plot randomized complete block designs in 2021 and 2022. The study found that the S and P application did not affect the soil availability of S and P. The effects of P application and sites were observed, where the addition of P significantly increased the dry below-ground biomass (BGB), and site with higher soil P had higher dry BGB compared to site with lower soil P. The fertilizer uptake efficiency indices showed that adding P and S reduced the fertilizer recovery efficiency and partial factor productivity. The results indicated that adding P increases the crop yield even in the soils with higher Mehlich-III (M-III) extractable P concentration. In higher P soils, the application of the S also influenced the tubers' specific gravity, which was higher at 90 kg S ha−1. In conclusion, this study observed the effects of P fertilizer application even on sites with M-III extractable P >250 mg kg−1. However, the interaction effects of P and S were inconsistent, potentially due to as high as 1200 kg ha−1 sulfate application through irrigation water.","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70086","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717104","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}

Production declined rapidly due to flooded floral hemp markets, but the industry is still viable in the state. Two of the most pressing questions about hemp management among growers in this region include cultivar selection and irrigation management. An outdoor hemp research trial was established in 2020 near Logan, UT (41.66 N, −111.91 W), to investigate fundamental irrigation strategies and cultivar performance. This trial (2020–2021) examined combinations of three hemp cultivars, four irrigation technologies, and three irrigation rates (100%, 75%, 50% of estimated evapotranspiration of corn [Zea mays L.] given lack of data for hemp) nested within each irrigation technology. Female hemp clones were transplanted in late May and harvested in September and October based on flower maturity. The irrigation technology (mid-, low-elevation spray, low-elevation precision application, and mobile drip) had no significant impacts on hemp yield or cannabinoid concentrations. Hemp biomass yield and cannabidiol concentrations often increased with less applied irrigation in all irrigation technologies. The three hemp cultivars responded similarly to irrigation management, although there was high plant-to-plant variability in delta 9 tetrahydrocannabinol (THC) concentrations. This research suggested that floral hemp could be irrigated less than other crops in the region, and irrigation requirements among some hemp cultivars may be similar. Further, robust and representative sampling protocols for THC monitoring are needed to ensure variability is accounted for.","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717168","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}

Recent legalization has renewed interest in industrial hemp in the United States, particularly in fiber production, which has a critical role in carbon (C) sequestration and various industries, including textiles and construction. A 2-year field experiment (2022–2023) was conducted at Rodale Institute—Pocono Organic Center, Blakeslee, PA, evaluating the performance of four hemp varieties (MS 77, Futura 75, Santhica 27, and Han NE) under regenerative organic systems. Seed rates were considered as 73 kg ha−1 for Santhica 27 and Futura 75, 135 kg ha−1 for MS 77, and 270 kg ha−1 for Han NE, targeting a plant population of 2.47 million plant ha−1 across varieties. Data on canopy cover, plant height, yields (biomass, stem, leaf, and flower), and cannabinoids were collected to assess the effects of variety and environmental conditions on growth and yield. Root samples from 2023 were also analyzed for arbuscular mycorrhizal fungi (AMF) colonization. Han NE demonstrated the highest growth, yields, and canopy cover, followed by MS 77, with more favorable growing conditions in 2023. Additionally, AMF colonization was consistent across varieties, reporting a higher colonization in MS 77 (45.37%), suggesting enhanced nutrient uptake and stress tolerance. Based on the results, Han NE and MS 77 are promising hemp varieties for fiber production in this region.

Key factors like row spacing not only affect resource utilization but also play a crucial role in weed suppression, especially in regenerative organic systems. This research at the Rodale Institute, Kutztown, PA, examined the effects of row spacing (19 cm narrow vs. 38 cm wide) and fertilization treatments (control, blood meal containing 12% N at 112 kg ha−1 and 224 kg ha−1, and compost at 60 t ha−1) on yield and chemical composition of industrial hemp seed (cultivar: Canda) over two growing seasons (2019 and 2020). The narrow row spacing increased plant and stalk density, boosting bast fiber yield, while wider spacing promoted weed biomass due to reduced crop competition. Higher temperatures in the late growing season in 2020 led to 3.5 times increase in biomass yield and improved grain protein content. Principal component analysis indicated that compost influenced nutrient availability and heavy metal uptake more strongly than row spacing or blood meal treatments. Blood meal had limited effects, likely due to insufficient application rates, but showed promise for minimizing heavy metal uptake compared to compost. Optimal crop performance depends on the interaction between climatic conditions and agronomic practices. Selecting appropriate row spacing and nutrient sources is essential for enhancing hemp production while reducing input costs and minimizing environmental impact.","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717108","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}

However, the way PSMs are affected by and respond to agricultural management is poorly understood. As part of the long-term agroecosystem research network, we assessed ecometabolomic profiles of corn (Zea mays L.) leaves and roots between contrasting prevailing (prevailing practice, PP) and alternative (alternative practice, AP) cropping practices, which utilized cover crops and cover crop interseeding. The ecometabolomic profiles of corn leaves and roots were 90% and 71%, respectively, richer in PSMs in the AP than PP treatments. Our untargeted metabolomic analyses resulted in 124 annotated features, with 68 features significantly different between AP and PP treatments. We detected 43 features annotated as PSMs, 39 of which were greater (p ≤ 0.10) in the AP than PP treatments. This research shows that our agricultural management practices influence the way plants respond within their agroecosystem.

Floral industrial hemp (Cannabis sativa L.) offered prospects in essential oils for medicinal, flavoring, and fragrance additives. One major limitation for growers is the expense of Δ9-tetrahydrocannabinol (Δ9THC) monitoring to meet legal compliance while maximizing cannabidiol (CBD) or cannabigerol (CBG) concentration for financial return. Cannabinoid analysis is not widely available, and shipping samples is legally challenging with state-by-state legislation. The study objectives were to evaluate whether near-infrared spectroscopy (NIRS) could be used to rapidly and inexpensively quantify commonly produced hemp cannabinoid concentrations compared to industry standard high-performance liquid chromatography (HPLC). A total of 448 tissue samples from 3 years of outdoor hemp cultivar, irrigation, and fertility trials were evaluated. Samples were dried and ground, and Δ8-tetrahydrocannabinol (Δ8THC), Δ9THCD, tetrahydrocannabinolic acid (THCA), CBD, CBG, cannabichromene (CBC), cannabinol (CBN), cannabidivarin (CBDV), cannabidiol acid (CBDA), and cannabigerol acid (CBGA) were determined by HPLC with a diode array detector as reference measurements, prior to analysis by NIRS. Calibration equations were developed to assess whether NIRS can estimate cannabinoid concentrations. The three cannabinoids of most importance for floral hemp production (THCA, CBDA, and CBD) had the widest range in concentrations and the best correlation (R2 = 0.71–0.87) between NIRS and HPLC, while other cannabinoids had limited concentration ranges and poorer correlation. The THC and CBD results are highly encouraging and indicate that NIRS is a robust tool for rapid and inexpensive quantification.","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70082","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707290","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}

The high salt content in soil and irrigation water poses a significant risk to agriculture's productivity and long-term viability. Soil salinity hinders crop development by impeding water absorption, causing osmotic stress, and altering nutrient accessibility. Similarly, increased salt levels in irrigation water directly impact the water quality used for agricultural irrigation. This can result in reduced crop output, slowed plant development, reduced nutrient absorption, and increased vulnerability to pests and diseases. To address these issues, farmers in arid regions use effective irrigation methods like drip irrigation, precision agricultural methods, gypsum that improves sodicity by supplying calcium ions, and salt-perennial salt-tolerated grass and crop rotation systems. Integrated management strategies, including efficient irrigation scheduling and soil conservation, can effectively handle soil and water salinity concerns in dryland agricultural regions. These methods encourage sustainable farming systems that maximize resource consumption, increase soil health, and boost crop output. Successful coping techniques require a comprehensive understanding of local variables, including soil and water quality, and crop requirements. Farmer education and awareness initiatives also play a crucial role in spreading information about salinity management measures and promoting their adoption.","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70072","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689129","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}
