Fostering and maintaining soil health via holistic management is a central goal for most organic farmers. However, many questions remain regarding how different management practices influence soil health in farm fields. In this study, we used a mail‐in soil survey to assess how organic management practices such as crop diversity, perennials in rotation, tillage, manure use, and subscription to soil cation balancing influence soil biochemical health indicators in certified organic corn (Zea mays L.) fields. Organic farmers (n = 195) from the eastern Corn Belt mailed in soil along with a completed management survey to a research lab for analysis. Soils were analyzed for mineralizable carbon (C), permanganate oxidizable carbon (POXC), soil protein, texture, and routine soil nutrient analyses. Soil texture had the largest influence on soil biochemical health indicators, underscoring the need to consider soil type with soil health assessments. Crop diversity was negatively correlated with mineralizable C, soil C, and soil nitrogen (N) (r = –.19 to –.24) at p < .05 when perennials were in the rotation. This was attributed to tillage frequency increasing with crop diversity across all soil types. The presence of a perennial in rotation influenced soil biochemical health indicators, except for total C. Additionally, mineralizable C significantly increased when perennials were left in rotation for longer periods of time. This study demonstrates the effectiveness of incorporating management survey data with soil biochemical health analyses. We conclude that a main management driver for improved soil biochemical health in organic corn production systems is to reduce tillage intensity and incorporate perennials.

Organic dairy producers have distinct perspectives, approaches, challenges, and experiences when managing herd health, but little research has been conducted to develop a deeper understanding of producer decision-making related to disease-prevention and treatment strategies. We used 23 semi-structured interviews with organic dairy producers to better understand their perceived herd health challenges and overall disease-prevention strategies; decision-making and attitudes related to vaccination; and approaches to the treatment of infectious diseases using alternative or conventional antimicrobial therapies. Organic dairy producers reported improvements in overall animal health after they transitioned from a conventional to an organic system. Outdoor access, a balanced forage-based diet, and animal and environmental cleanliness were reported as the predominant disease-prevention measures. Over half of producers vaccinated their animals, and almost all preferred to use vaccines sparingly. Among producers who did not use vaccines, reasons cited were low perceived risk for infectious disease and minor vaccine safety concerns, yet many were not opposed to using vaccines in the future. Non-antimicrobial therapies were viewed as alternative effective treatment strategies for most common infectious diseases. Producers used antimicrobials very rarely and generally reserved them for severe cases when alternative treatments failed. Because US organic standards prohibit selling milk from cows that have ever been treated with antimicrobials, producers described the decision to use antimicrobials as extremely challenging and involved balancing considerations of economics, convenience, and animal welfare. This research fosters a better understanding of organic dairy producers' disease-prevention and treatment strategies and could be used by veterinarians and other animal health specialists to facilitate services for organic clients.

Although the emergence of large confinement operations out of a system previously dominated by mid-sized confinement has been one major structural trend in Wisconsin dairy farming since the 1990s, a second structural trend has been the significant emergence of moderate-sized dairy farms using alternative management strategies: management-intensive rotational grazing (MIRG) (25% of Wisconsin's dairy farms), organic production (3%) and Amish farm production practices (5–7%). This paper presents the first systematic and representative comparative study on the structure, behavior and performance of multiple pasture-based dairy farm strategies. Wisconsin is an ideal site for this study given the prevalence of pasture-based farms, yet many of the findings here should be relevant for other traditional dairy states where similar types of alternative farm management systems are also emerging. Divergence with respect to farm strategy has implications for structure, technology and management adoption patterns as well as farmer satisfaction levels. Our findings suggest that alternative dairy farming systems are likely to become more prevalent on the agricultural landscape of Wisconsin.

Bounded rationality is an especially appropriate framework for organic dairy adoption decisions as it recognizes internal and external constraints which are critical in understanding complex farm decision making. Farmers use of, and access to, information is examined using interview data gathered from organic, conventional, managed graziers, and Amish dairy farmers in Southwestern Wisconsin at a time when organic milk prices offered a 50% premium over conventional prices. Focusing on certain aspects and impressions of organic dairy, such as the sentiment that “milk is milk”, may lead to information satisficing where farmers do not take full advantage of the information available to them. Organic farmer interviews reveal the challenges they faced with bounded rationality constraints and how they countered these challenges with the help of social networks, as well as how situational factors such as economic and health crises may have motivated them to adopt organic dairy. The interview data from organic and conventional farmers alike also reveals how many conventional dairy farmers utilized information strategies which did not fully consider the pros and cons of the organic system. A bounded rationality framework could enlighten policy makers and educators as they tailor sustainable agricultural policy design and information dissemination strategies to serve the diversity of farmers on the landscape.
