However, knowledge gaps persist in optimizing agronomic practices, including precision nitrogen (N) management, which is crucial for yield and phytochemical quality, for example, delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). Addressing these gaps, a 2-year field trial (2022 and 2023) was conducted at the Rodale Institute-Pocono Organic Center in Blakeslee, PA, aiming to optimize CBD hemp production through precision N management. Forty experimental plots were established, with each assessing two main factors: (i) N rate: 0, 56, 112, 168, and 224 kg N ha⁻¹ using an OMRI-listed fertilizer, blood meal (12% N) and (ii) application method: banding and broadcasting. The 3-week-old hemp seedlings were transplanted into main plots, followed by fertilizer application and drip irrigation. Parameters including plant height, bud weight, biomass, and CBD yield were assessed, alongside CBD and THC concentrations in floral components and N concentration in leaves and flowers. There was a significant interaction of N rate and application method, impacting biomass yield, while the N rate also influenced CBD concentration. Blood meal supplied at 224 kg N ha⁻¹ yielded the highest biomass and elevated CBD and THC concentrations; however, this did not differ significantly from 168 kg N ha⁻¹ application. Therefore, the recommended optimal N fertilizer rate for Northeastern CBD hemp production is 168 kg N ha⁻¹, with an upper limit of 224 kg N ha⁻¹. Furthermore, the banding method of fertilizer application was more effective than broadcasting.</p>","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70028","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121090","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 objective of this study was to determine the effects of annual forage crop rotations of varying intensity, diversity, forage removal, and associated tillage practices on soil physical and chemical properties. A long-term forage study was conducted near Garden City, KS. The six rotation and tillage combination treatments of the study were (1) forage sorghum (<i>Sorghum bicolor</i> (L.) Moench)–forage sorghum (FS–FS) no-tillage (NT), (2) triticale (×<i>Triticosecale</i> Wittm. ex <i>A. Camus</i> [<i>Secale × Triticum</i>])/FS–FS–oat (<i>Avena sativa</i> L.; T/FS–FS–O) reduced till (RT), (3) T/FS-FS-O NT, (4) T/FS–FS–FS-O NT, (5) T/FS–FS–FS–O RT, and (6) T–FS–O NT. Soil samples were taken in 2021 and 2022 at depths of 0–5 cm and 5–15 cm from the experimental plots and adjacent land used for grain production in a wheat-sorghum-fallow rotation. Results of the study indicated that the less intense rotation, T-FS-O, had more water stable microaggregates, the grain control had smaller macroaggregates, and T/FS-FS-O RT had larger macroaggregates and tended to have fewer small aggregates. Similarly, diverse forage rotations like T-FS-FS-FS-O had larger sized (2.0–6.3 mm) dry aggregates and tended to have fewer smaller aggregates. The grain control had more medium sized (0.42–0.84 mm) dry aggregate than T/FS-FS-O RT. Soil total nitrogen concentrations were less for less diverse or less intense forage rotations compared with the grain control, and soil organic carbon (SOC) and P were less for all forages compared with the grain control, perhaps because forage harvesting reduced crop residue cover and organic matter cycling. We conclude that forage systems that remove biomass from the field should be integrated with management that leaves more residue on the soil surface, such as allowing forage regrowth after hay harvest, alternating between hay removal and grazing, or rotating between forage and grain crops to keep more residue on the soil surface to maintain SOC and protect the soil from erosion.</p>","PeriodicalId":7567,"journal":{"name":"Agrosystems, Geosciences & Environment","volume":"8 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/agg2.70031","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121044","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 collaborative study aimed to evaluate the immediate effects of cover cropping, comprehend the connections between soil health indicators, and measure quality indices for both mineral and organic soils. Across Florida, we conducted a comprehensive on-farm study, gathering 272 samples from both mineral and organic surface soils, which were treated with winter or summer cover cropping, rice cultivation, and fallow or flooded fallow. After analyzing 12 health indicators, we employed statistical methods such as mean comparison, non-parametric correlation, and regression for both pre- and post-cover cropping periods. A modified Comprehensive Assessment of Soil Health scoring system was utilized to assess the quality indices of both soil types. Notably, cover cropping enhanced cation exchange capacity (CEC) and soil protein (SP) in organic soil while preserving an unchanged active carbon (AC) pool. In mineral soils, such practices improved CEC, organic matter, maximum water holding capacity, SP, and total Kjeldahl nitrogen while reducing bulk density and AC. Following cover cropping, correlations among indicators became more pronounced, emphasizing the intricate relationships among soil properties and essential nutrients. Despite this alteration, the health indices did not change in both soils after cover cropping.

Past studies suggest that the observed yield effect varies (i.e., negative, positive, or insignificant), often depending on the applied cover crop species used, weather conditions, and farm management practices implemented (among others). In this study, we examine the short-run (i.e., 1 year) yield impact of four different cover crop families—grasses (<i>Poaceae</i>), broadleaves (<i>Brassicaceae</i>), legumes (<i>Fabaceae</i>), and others—both as single-family groups and as mixtures. Data from side-by-side on-farm experimental plots in six Eastern US states were collected from 2017 to 2019 in order to achieve the objective of the study. Statistical analysis of this multi-year plot-level data suggests that the majority of the cover crop families and mixtures investigated in this study do not have a statistically significant short-run effect on subsequent corn yields. In some cases, cover crop treatment even resulted in short-run yield losses (i.e., a yield penalty). These results imply that cash crop yield benefits from cover crop adoption are likely not going to be observed with just 1 year of use.
