In many areas where center-pivot irrigation methods are used, the most common sprinkler package is called mid-elevation sprinkler application, known as MESA. Two alternative sprinkler packages designed for better water use efficiency are called low-energy precision application, or LEPA, and mobile drip irrigation, called MDI. A recent study evaluated how MDI and LEPA—at full and reduced irrigation rates—impact alfalfa and silage corn yield and quality in trials on two farms in Utah.

Global market demands for barley are less than cereals such as corn, rice, and wheat, but barley plays a particularly important role in cropping systems in areas of high elevation and/or latitude with short growing seasons. Estimation of residue nutrient uptake requires both a knowledge of the biomass produced, as well as the concentration of individual nutrients. These factors were evaluated in 2018 and 2019 from trials of four barley classes at five locations in southern Idaho.

Late-maturity alpha-amylase or LMA is a weather-related event that lowers the quality of affected grain, resulting in sticky breads, cakes, and noodles with unattractive and undesirable textures. Grain that has been affected by LMA, or that is susceptible to LMA, cannot be identified by sight alone due to varietal- and environmental-induced differences in appearance and differences in rates of development. Techniques that allow for rapid identification of the LMA susceptibility window in wheat and knowledge of the weather events that lead to LMA can empower growers to manage and mitigate LMA-induced profit loss.

New high-yielding spring wheat cultivars are being grown widely across the Canadian Prairies. As yields rise, grain protein levels can only be maintained by increasing the N availability to crop, often reducing fertilizer use efficiency. An additional concern when increasing the amount of N fertilizer being applied to the crop is the increased risk of lodging, reducing the crop’s yield, quality, and harvestability. This article reports on research evaluating the effect of agronomic management practices on spring wheat lodging risk, grain yield, and protein content in the eastern Canadian Prairies.

In general, winter wheat yields are maximized when planted in October in Kentucky. However, it is common for wheat planting to be delayed until November due to limited resources, equipment problems, and/or weather conditions. Two agronomic strategies were investigated to determine whether either could mitigate yield reductions following delayed wheat planting: increased seeding rate and in-furrow phosphorus.

Potassium (K) is an essential element for crop growth, playing a key role in photosynthesis, protein synthesis, and many other essential functions in the plant. In 2020, 44% of the soils sampled across North America tested below critical in K (meaning applying K fertilizer would result in a crop response). Assessing soils for nutrient availability is an important principle of 4R Nutrient Stewardship. The goal of this article is to provide information on the behavior of K in soils and how it influences the assessment of crop K needs.

Semiarid regions in southern Idaho receive a small amount of annual precipitation (e.g., 9–12 inches), and crop options are very limited in dryland farming without supplemental irrigation. To diversify cropping systems, growers can incorporate crops with lower water requirements through rotations and intercropping. Field trials were conducted to evaluate crop yield and soil health in barley–pulse intercrops under full and deficit irrigation with no supplemental N fertilizers.

Across the U.S., we are withdrawing water far faster than our aquifers are naturally replenished. One of the challenges of determining how much water is left in aquifers is that decline rates are extremely variable over space and time and regulations governing groundwater withdrawal are highly localized. Over the long term, pumping water out of the ground faster than it’s replenished is like deficit spending; it will catch up with you.

A great deal of attention and financial resources are devoted to incentivizing farmers to adopt practices known to protect soil, water, air, and biodiversity. Many commodity groups, including those representing cotton, corn, soybeans, and rice, have set goals and made climate commitments that rely on the uptake and longevity of conservation practices by U.S. producers. Despite these efforts, adoption of two primary practices, cover crops and conservation tillage, remains low. In order for these goals to be met, change is going to have to happen much faster than the current pace.

Black oat is a cool-season annual grass with Mediterranean origin. In contrast to other cool-season grasses, black oat is more heat tolerant and disease resistant, making it an attractive option for the US upper Midwest, since it can be utilized during summer, when there is decreased productivity of cool-season forages due to photorespiration. The objective was to evaluate 10 black oat breeding lines for herbage accumulation, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and in vitro digestible organic matter (IVDOM) concentrations.

Controlling future phosphorus (P) loss will not be simple. The main nutrient “culprit” in freshwater contamination, P, becomes available only in its dissolved inorganic form in solution; and that solubility is also what can contaminate the environment if the P ends up in the wrong place. This article examines future P loss measures for agricultural systems. Beyond continued vigilance with regards to best management practices (BMPs), future mitigation tools include physical filters of P loss from crop fields, updating P soil-test calibrations, stream buffers, cover crops, biologic products that may alter P availability, enzyme additives, and potential P recycling and trading markets.

Can we reduce phosphorus (P) rates and loss to the environment by banding? The thinking goes that any system that places P fertilizer below the surface without significantly increasing soil erosion will reduce P losses to the environment. Can application rates be reduced? The short answer is “it depends.” Decades of related research have conflicting conclusions. It’s of particular interest due to fertilizer prices and because agriculture is in the hot seat to cut P and nitrogen (N) losses to water bodies. Efficiencies from banding phosphorus (P) do exist in corn at very low soil-test P levels, where cool or wet conditions limit root growth and nutrient uptake, and in soils that make applied P less available.

Some questions most often asked by producers are, “What is changing in my soil when I adopt a management practice? How can I detect that change? and What does it mean for my yields?” These questions reveal our uncertainty in how we quantify changes in the soil and how we view the soil. More importantly, they give insight into what is important to producers for their operations. The current attention on soil health has revealed that we don’t completely understand how soil changes and what is required to determine what is changed in our soils. The focus of this article will be on what actually happens in the soil along the journey of change in corn and soybean systems in the upper Midwest.

Farmers, ranchers, and foresters are facing increasing challenges related to changing climate and weather, manifested in rising average temperatures, more frequent extreme rainfall events, extended drought, and heat waves. These changes are also impacting pest abundance and distribution, creating new pest problems and straining current pest management options and decision-making. Key factors for U.S. agriculture and producer resilience in tackling new environmental and pest challenges lie in the ability of producers to apply effective, economical integrated pest management (IPM) approaches and in support for research and development of new and renewed IPM tactics and systems to meet 21st century needs.

Research has shown the benefits of diversifying crop rotations, yet many Prairie farmers keep their rotations short and simple with cereals and oilseeds or cereals and pulses being intensively grown in two-year rotations. As western Canadian farms are pressed to increase yields while reducing inputs and the environmental impact of food production, growers need help to determine what crop rotations can help them achieve these goals and remain economically viable. This article reports on research evaluating yield and yield stability, nitrogen use efficiency, and net economic returns of six crop rotations in the Southern Prairies, Northern Prairies, and Red River Valley ecozones of western Canada.

As the cost of soybean seed increases, farmers are interested in reducing seeding rates. Variable-rate seeding (VRS) allows farmers to adjust seeding rates within a field by management zone, and many farmers practice VRS in soybean. However, without field validation, the accuracy of existing VRS practices is unknown. The objectives of this study were to: (a) determine the agronomic optimum seeding rate (AOSR) of soybean in predetermined management zones and (b) compare the AOSR to each farmer's standard VRS practice.

Irrigation has the potential to increase crop yield and financial return on coarse-textured, coastal plain soils in the mid-Atlantic region of the United States. Although the majority of irrigation is delivered through overhead sprinkler irrigation, subsurface drip irrigation (SDI) has been shown to be a reasonable alternative to sprinkler irrigation because of its efficiency on small, irregularly shaped fields. The objective of this paper was to compare the yield and financial return of SDI with those of dryland production over the life of the SDI system (2001–2013).

As a result, crop yields were disastrously lower than normal, and the regional median residual soil nitrate-nitrogen after wheat was two to three times higher than the running average. This drought brings new light (and old memories) to soil testing for nitrogen along with new challenges and opportunities.

Certified organic food and fiber production is an increasing portion of the U.S. agricultural sector. Expanding production reflects growing consumer demand for these products based on perceived food quality benefits rather than purchases on a unit price basis. While the majority of certified organic products consist of fruits, vegetables, and grains, there is also a demand for organic forage to produce organic meats and dairy products. This article seeks to determine the cost of transitioning from conventional to organic production using perennial and annual forage systems.

While a comprehensive economic analysis of cover crops accounting for all soil ecosystem services from cover crops is lacking, the available studies indicate that cover crops have potential to provide positive net returns if biomass production is sufficient. Among the opportunities to generate positive economic outcomes from cover crops include grazing and harvesting cover crops, savings on herbicides and fertilizers, carbon credits, and monetization of soil ecosystem services.

Data from 100 farmers indicate increased net farm income as a result of adopting soil health practices. Soil health practices are marginal changes from conventional production methods with most seasonal activities and inputs remaining unchanged. Changes in management do require considerations for local soil and climate. Transitioning to soil health systems can be a gradual process, and it may take many years to achieve full benefits of reduced inputs and increased productivity. The Assessing Soil Health Series is part of a larger Soil Science Society of America webinar series produced in partnership with The Soil Health Institute and sponsored by The Walton Family Foundation.

Tobacco thrips and tomato spotted wilt (TSW) orthotospovirus can reduce peanut yield. Systemic insecticides are applied in the seed furrow at planting and to peanut foliage to reduce injury from tobacco thrips and decrease incidence of TSW. Research was conducted in Georgia, North Carolina, South Carolina, and Virginia to compare the effect of the following treatments on tobacco thrips feeding injury and expression of TSW in peanut: thiamethoxam seed treatment, thiamethoxam seed treatment followed by acephate three weeks after planting, phorate applied in the seed furrow at planting, and a nontreated check.

Elemental sulfur (S) is produced in large quantities in both the U.S. and Canada as a by-product of fossil fuel production. However, this form of S must be oxidized to sulfate (SO42–) by soil microorganisms before crops can utilize it and therefore may not meet crop S requirements in the year of application. Rapid oxidation can be obtained if elemental sulfur particles are less than 20 μm in size and effectively dispersed in soil under favorable moisture and temperature conditions.

Soils are the largest organic carbon pool on the land surface, and agricultural soils that have been disturbed by tillage and other practices for many years have lost carbon to the atmosphere. This historical loss, however, means that there is substantial opportunity to increase soil organic carbon (SOC) in agricultural soils by adopting practices that reduce soil disturbance and increase carbon from organic matter. This article is an excerpt from Field to Market’s 4th National Indicator Report, released in December 2021. This is Part 3: Soil Carbon.

Agricultural lands play a critical role in ensuring clean water for society and ecosystems throughout the country. Complex weather factors, and the complexity of the biogeochemical cycling of nutrients and the fate and transport of chemicals in the soil, make it particularly challenging to quantify water quality and to attribute changes to any specific cause. Therefore, tracking water quality change is a long-term endeavor. Fortunately, there is ample evidence from research at field and watershed scales that certain agricultural practices retain nutrients and soil in the field and thereby reduce the risk of losing nutrients and chemicals to waterways. This is Part 4: Water Quality.

Nutrients are essential for plant and animal agriculture and comprise a large portion of its outputs. The starting point for assuring beneficial impacts is the adaptive management built into 4R Nutrient Stewardship. To manage adaptively means to evaluate impacts in your decision cycle. The metrics you evaluate need to reflect impacts important to your local farming system. Farther-reaching impacts of crop nutrition include water quality, air quality, carbon footprint, biodiversity, food security, human nutrition, farm livelihoods, and circularity. By better documenting the decision cycle, our current and past practices, and their relation to impacts, the industry has the opportunity to build public trust.

Faced with the daunting task of herbicide resistance management, Australian farmers developed various systems to target weed seeds during crop harvest. These systems are collectively called harvest weed seed control (HWSC). Despite being relatively unheard of in the U.S., currently more than 80% of Australian farmers practice HWSC. This article provides an overview of the six HWSC systems and the research conducted to date in U.S. cropping systems. This article also includes information for implementing HWSC, what weeds to target, potential costs, and where to find equipment.

In 2021, in the Corn Belt, rising corn prices fueled producer willingness to make “insurance” fungicide applications to hedge against possible yield losses from foliar disease. Newer disease risks—especially tar spot—also spurred some producers toward a more aggressive spray program. Market realities mean that “insurance” fungicide applications are likely to continue in 2022. But crop costs and returns will change, and CCAs should help their producers keep in mind corn fungicide fundamentals—even when sky-high prices may impact decision-making more than disease management fundamentals.

Hypoxia in the Gulf of Mexico is an environmental issue connected to agricultural crop management in the Mississippi River watershed. Programs to improve nutrient stewardship in this watershed aim to improve nutrient use efficiency and reduce losses of nitrogen and phosphorus. Trends since the 1980s show increases in both crop production and the size of the hypoxic zone while the trends in nitrogen surplus have neither increased nor decreased. Provisional flow-normalized river loads of nitrogen are decreasing. While improvements in adoption of 4R management of applied fertilizers and manures have been noted, opportunities for improvement also remain. While 4R practices will not solve the issue on their own, they can make an important contribution when integrated with soil conservation practices and changes to whole farming systems.

Flue-cured tobacco is the most valuable crop produced in North Carolina. It is susceptible to glufosinate, yet it is commonly grown in close proximity to crops that are tolerant to the herbicide. Although field trials found simulated glufosinate drift onto flue-cured tobacco significantly reduced per-acre yields, it did not affect the crop’s per-acre value. Nevertheless, growers and applicators should strive to minimize drift, which starts with reading, understanding, and following product labels.

More and more farmers these days are putting regenerative practices into place on the land they own for the long-term sustainability of their operations. But what happens farmland that is rented out? Many of the practices behind regenerative agriculture like building soil health and biodiversity and limiting the need for external inputs, provide benefits that are seen over time and not necessarily year to year. Renters often lack the leverage with the landowner to put regenerative practices into action.

The bermudagrass stem maggot (BSM) severely damages bermudagrass pastures and hayfields throughout the southeastern United States every summer. This management guide can help forage managers and consultants identify BSM damage and the pest. Pyrethroid insecticides can reduce adult BSM populations and yield loss when applied correctly. More research is needed to develop integrated pest management plans that include multiple suppression efforts. Fine stem lines are more susceptible to BSM damage than lines with thicker stem. Long-term solutions require new BSM-tolerant lines to reduce the demand that producers currently place on pesticides.

While we know herbicide resistance is an inevitable fate in a system that relies heavily on herbicides, we can work together to focus on long-term strategies to delay its development and spread. Managing for a single year is a key reason why we are in the situation we are in today. A review of how herbicide resistance issues developed over time provides some insight into this and also some guidance into how we can more effectively deal with the problems we face now and into the future. Farmers rely heavily on their advisers to provide sound agronomic recommendations, and we, as advisers, need to take that role seriously to broach the subject of long-term weed management beyond individual-year herbicide recommendations.
