The first Agricultural Revolution was the transition from hunter-gatherer to the settled agriculture about 8,000 BC. The second Agricultural Revolution occurred between the seventeenth and nineteenth centuries when farm size increased, farm mechanization occured, and agricultural products were commercialized and traded. The third, or “Green Revolution,” began in the early twentieth century when genetically improved and dwarf varieties of cereals (rice [ Oryza sativa L.], wheat [ Triticum aestivum L.], and corn [ Zea mays L.]) were grown with heavy inputs of agro-chemicals (fertilizers and pesticides), leading to drastic increases in crop yield (Chakravarti 1973; Borlaug 2001; Hardin 2009), but severe adverse effects on the environment (John and Babu 2021). The Green Revolution had two interrelated stages: from 1960 to 2000 it was based on seed-centric technologies (Borlaug 2001), and 2000 to 2020s it was based on soil-centric technologies with focus on soil carbon (C) sequestration (Lal 2004), eco-intensification (Martin-Guay et al. 2018), impact (Evenson and Gollin 2003), and adaptation to and mitigation of anthropogenic climate change (Lal 2013; Lal et al. 2011; Muñoz and Zornoza 2018; Hou 2021). The soil-centric Green Revolution, based on judicious management of soil, crops, water, climate change, etc., paved the way for the use of artificial intelligence (AI), and thus transformation into a fourth Agricultural Revolution.

Understanding the cost-effectiveness of different strategies for mitigating nutrient pollution is critical to making informed decisions and defining expectations that best utilize limited resources, which is a research priority for the US Environmental Protection Agency. To this end, we modeled nutrient management practices including residue management, cover crops, filter strips, grassed waterways, constructed wetlands, and reducing fertilizer in the upper East Fork of the Little Miami River, an 892 km2 watershed in southwestern Ohio, United States. The watershed is 64% agriculture with 422 km2 of row crops contributing an estimated 71% of the system’s nutrient load. The six practices were modeled to treat row crop area, and among them, constructed wetlands ranked highest for their low costs per kilogram of nutrient removed. To meet a 42% phosphorus (P) reduction target for row crops, the model results suggested that the runoff from 85.5% of the row crop area would need to be treated by the equivalent of 3.61 km2 of constructed wetlands at an estimated cost of US$2.4 million annually (or US$48.5 million over a 20-year life cycle). This prompted a series of projects designed to understand the feasibility (defined in terms of build, treatment, and cost potential) of retrofitting the system with the necessary extent of constructed wetlands. The practicalities of building this wetland coverage into the system, while leading to innovation in unit-level design, has highlighted the difficulty of achieving the nutrient reduction target with wetlands alone. Approximately US$1.2 million have been spent on constructing 0.032 km2 of wetlands thus far and a feasibility analysis suggests a cost of US$38 million for an additional 0.409 km2. However, the combined expenditures would only achieve an estimated 13% of the required treatment. The results highlight the potential effectiveness of innovative design strategies for nutrient reduction and the importance of considering realistic field-scale build opportunities, which include accounting for acceptance among landowners, in watershed-scale nutrient reduction simulations using constructed wetlands.","PeriodicalId":50049,"journal":{"name":"Journal of Soil and Water Conservation","volume":"48 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141152698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conservation crop rotation involves growing a series of crop phases in a field, reducing fallow periods and enhancing N demand. The objective of this study was to contrast conventional rotations of corn–soybean (CS) with conservation rotations of corn–soybean–winter wheat ( Triticum aestivum L.; CSW) as N management tools using a mass balance approach. We calculated N balances (∑Inputs – ∑Outputs) and loads, as both nitrate-N (NO3−-N) and total N (TN), for fields with CS ( n = 18) and CSW ( n = 12) rotations to examine crop- and rotation-specific patterns of N surplus, deficit, and loss. Using data from all individual years ( n = 169), we found median N balance indicated surplus N in corn phases (CSW-corn: 112 kg N ha−1; CS-corn: 51 kg N ha−1) compared to N deficits in wheat (−1.3 kg N ha−1) and soybean (CS-soybean: −110 kg N ha−1; CSW-soybean: −92 kg N ha−1) phases. Median N loss was least in wheat (8 kg NO3−-N ha−1; 11 kg TN ha−1) and soybean phases (CS-soybean: 18 kg NO3−-N ha−1, 21 kg TN ha−1; CSW-soybean: 17 kg NO3−-N ha−1, 23 kg TN ha−1) and greatest in corn phases (CS-corn: 31 kg NO3−-N ha−1, 35 kg TN ha−1; CSW-corn: 27 kg NO3−-N ha−1, 34 kg TN ha−1). The median of average annual N balance was greater in CSW (14 kg N ha−1) than CS fields (−29 kg N ha−1), yet the medians of average annual N loss were similar (e.g., CSW: 19 kg NO3−-N ha−1; CS: 22 kg NO3−-N ha−1). These results suggest that including winter wheat into the CS rotation may have the potential to address N surplus pools and reduce N loss to downstream waters.","PeriodicalId":50049,"journal":{"name":"Journal of Soil and Water Conservation","volume":"96 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141152714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although many were installed by the newly formed USDA Soil Conservation Service, many others were designed without the benefit of local hydrologic data or technical design guidance. As a result, there is a wide range in the efficacy of these structures, and in many cases, the current status of hydrologic process interactions is unknown. In addition, structurally compromised, abandoned, and unmaintained structures are now interacting with runoff and sediment contrary to their intended purpose, in some cases exacerbating erosion. Because these structures are typically small relative to the resolution of available topographic data, they are not generally accounted for in runoff simulation models. Recent years have marked the increasing availability of LiDAR-based topographic data of sufficiently high resolution to incorporate water and erosion control structures in the digital elevation models underpinning hydrologic models. However, beyond the challenges of data acquisition, modeling tools capable of resolving berm topographies and characterizing their hydrologic impacts are needed. Here, the potential hydrologic impacts of water spreader berms are simulated in virtual experiments using a rainfall-runoff model (specifically, the Saint Venant Equations). The model simulations characterize the local and hillslope-scale effects of berms across a range of storm intensities, landscape attributes, and berm shapes while accounting for berm topography and elevated soil permeability upslope of berms in response to vegetation growth. We demonstrate how berms alter surface runoff and create spatially varied runoff patterns, and describe the impact of berm removal on re-establishing connectivity patterns.","PeriodicalId":50049,"journal":{"name":"Journal of Soil and Water Conservation","volume":"17 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141152707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ecological information includes soil properties (e.g., texture class), geomorphology characteristics (e.g., slope aspect), and ecosystem dynamics (e.g., plant succession), which are critical covariates in rangeland monitoring programs such as the Assessment, Inventory, and Monitoring (AIM) strategy conducted by the Bureau of Land Management (BLM). Based on field observations, AIM identifies ecological sites according to ecological site concepts uniquely developed within individual Major Land Resource Areas (MLRA). Here, we present and evaluate the availability of ecological site identification, soil observations, and geomorphology characteristics determined by AIM data collectors between 2012 and 2021 in 14 states of the western United States. There are 31,267 monitoring plots (79% of plots) with identified ecological sites and 29,228 plots (74% of plots) containing soil morphology descriptions of soil horizons examined in excavated pits. While soil texture class is observed in most soil horizons (98%), rock fragment volume is the soil property with the least data availability (75%). The consistency of soil data (e.g., clay content observations within the ranges of texture classes) increases as a function of time following guidance in soil profile description training for AIM data collectors. Nearly 47% of AIM plots are found on gentle slopes of 0% to 5% steepness and on Flat/Plain and Hill/Mountain landscape types. We confirmed that the AIM database is a robust source of georeferenced soil and geomorphology information that can be used for land management and research on land potential, soil geography, and assessment of soil health indicators across the western United States.","PeriodicalId":50049,"journal":{"name":"Journal of Soil and Water Conservation","volume":"23 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141152601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent decades, extensive afforestation activities have been undertaken in marginal lands of the semiarid northern Negev region of southern Israel to mitigate such degradation processes. However, the long-term impacts of these actions in drylands, subjected to long-term drought episodes, remain unknown. We investigated the impact of landuse change from natural lands to afforestation runoff-harvesting systems—through intensive earthworks (landforming) to establish a contour bench terrace during long-term drought—on herbaceous vegetation productivity, and assessed its temporal dynamics across the multi-aged Ambassadors’ Forest. The MODIS MOD13Q1 and MYD13Q1 maximum value composite products were used to calculate normalized difference vegetation index (NDVI) data for the hydrological years 2000 to 2020. For this study, implemented in 2021, we selected three locations within the Ambassadors’ Forest: (1) 15-year-old afforested hillslopes, (2) 11-year-old afforested hillslopes, and (3) 4-year-old afforested hillslopes. We further delineated undisturbed hillslopes near these sites as a reference treatment. We found high spatiotemporal variability in vegetation cover. Over the short term, and specifically in the first hydrological year following the establishment of the water-harvesting systems, a substantial reduction in mean annual NDVI was observed, with values ranging from 30% to 65% lower compared to the reference sites. However, the negative impact of landuse change diminished over time, suggesting that (1) self-restoration processes occurred over a longer term after landuse changes were implemented, and (2) the establishment of water-harvesting systems improve the conservation of runoff water at the hillslope. This effect was observed for the 11- and 15-year-old afforestation sites, where vegetation productivity was 8.9% and 31.0% greater, respectively, than in the respective reference sites ( p < 0.05). Although the long-term drought occurred during the construction of the water-harvesting systems, these findings are in agreement with previous studies. Specifically, this study suggests that ecological self-restoration processes in semiarid regions occur approximately a decade after runoff-harvesting systems are established through earthworks.","PeriodicalId":50049,"journal":{"name":"Journal of Soil and Water Conservation","volume":"9 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140033255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dramatic loss of dairy farms throughout the region over the past 30 years has contributed to an unraveling of the fabric of its rural communities (Spratt et al. 2021). An important driver of this trend has been extreme volatility and a downward trend in real (i.e., inflation-adjusted) farmgate milk prices. In response, many remaining dairy farms have greatly increased herd size and milk production per cow; “get big or get out” has been the clear writing on the proverbial wall. Farmers who have followed this path have generally demonstrated an impressive application of science, technology, and management to consistently produce an average of over 25,000 lb of milk per cow per year in herds with hundreds or thousands of cows. Unfortunately, there are a host of vexing issues associated with the increasing trend toward large modern confinement-feeding dairy farms. These farms are very capital-intensive and the resulting level of assets (and debt) per cow necessitates maximum milk production per cow (Winsten et al. 2000, 2010). Very high grain-to-forage feeding ratios can increase the incidence of metabolic disorders, resulting in increased use of antibiotics and increased culling rates. The very high capital requirements preclude most farm workers from becoming farm owners. The use of heavy equipment and manure-handling systems is associated with higher rates of worker injuries and fatalities (Douphrate et al. 2013). From an environmental perspective, large modern dairy farms often import much more nutrients (e.g., grain and fertilizer) onto the farm than the farm’s land base can assimilate (Kellogg 2000).

The experiment was organized as a randomized complete block design (RCBD) with a split-plot arrangement. The experiments were conducted under transitional no-till at Prosper and Hickson, North Dakota, from 2017 to 2019. Forage pea ( Pisum sativum L.), faba bean ( Vicia faba Roth), and winter camelina ( Camelina sativa [L.] Crantz) were established into spring wheat stubble in August of 2017 and 2018. A check treatment with no cover crop was included. Cover crop fall biomass production and nitrogen (N) accumulation in plant tissue averaged across locations were 1.59 Mg ha−1 and 67.7 kg ha−1, respectively. Winter camelina survived the winters and accumulated biomass in the spring, resulting in significantly higher biomass (3.3 Mg ha−1) than the previous fall biomass. Winter camelina decreased spring water content in Prosper and Hickson in 2018, affecting maize seedling growth because of early competition. Soil NO3-N was not different among treatments. Maize was planted into the residue of fall-planted cover crops. Nitrogen rates of 0, 40, 80, and 160 kg N ha−1 were applied immediately after planting as urea. Maize grain yield increased with higher N rates and was significantly higher when grown in plots that had faba bean (9.7 Mg ha−1), forage pea (10.1 Mg ha−1), and the no-cover crop check (9.8 Mg ha−1), than those that had winter camelina (8.6 Mg ha−1). Leguminous cover crops resulted in a slight increase in maize grain yield compared with plots without cover crops. However, this increase did not reach statistical significance.

Soil samples were taken to represent whole plot soil means for both treatments, while in-band (IB) and between-band (BB) soil samples were taken in injected plots to assess nutrient spatial distribution after injection. Corn silage yield and N uptake did not differ between injection and broadcast treatments at 7 of 8 sites but was greater under injection in the one site that did not receive a sidedress N application. No consistent differences in soil NO3-N were seen between treatments; however, a clear alteration in soil NO3-N spatial distribution was observed with IB > BB = surface. Manure injection did not result in any consistent differences ( p > 0.05) in POXC or C-min compared to broadcast plots, nor did it result in an alteration in their spatial distribution. This study shows manure injection alters the spatial distribution of soil NO3-N, specifically elevating it in the injection band, but this was difficult to pick up when using the equi-spaced method to represent the whole injection application area.

Scientific approaches to realize sustainable water futures in complex systems, such as those described recently by Elias et al. (2023) and Talchabhadel et al. (2021), require integrated science combined with holistic, collaborative management by stakeholders to achieve desirable, meaningful results. While integrated science can identify possible and/or probable outcomes for water futures, it is stakeholder-driven decision-making and implementation that will determine and realize preferred outcomes for sustainability. Researchers’ knowledge alone, no matter how good, is not likely to alter stakeholder actions or probable outcomes. It will be stakeholder preferences and choices based on a myriad of factors—not just science-based information—that will determine the actual outcomes. The seemingly intractable “wicked problems” relating to water sustainability seem to persist in the face of new information and advancing science produced by research. Many of the challenges that arise in wicked problems cut across traditional boundaries (both physical and figurative), including disciplinary, biophysical, sectoral, social, and jurisdictional ones.
