The crop rotation is a farm-scale management choice that dictates agronomic output, ecological impacts, and farm viability. Rotations have become less diverse recently. Re-diversifying may help agricultural systems meet the growing, dynamic demands from society challenges climate change. Using long-term experiment, we tested whether diversified rotations could a) match productivity (grain yield) of simplified while b) stabilizing against variable weather in western U.S. Corn Belt. We...
Abstract Computational design in agriculture is the use of data‐driven systems and tools to propose evaluate alternative configurations agricultural systems. It unique from digital that it integrates computational crop science approaches formulate problems rather than mitigating by applying technologies. In this special issue, we highlight how could be used adapt better meet societal goals more rapidly at lower cost. Many disciplines within sciences are represented, breeding cropping...
There is increasing global demand for food, bioenergy feedstocks and a wide variety of bio-based products. In response, agriculture has advanced production, but increasingly depleting soil regulating supporting ecosystem services. New production systems have emerged, such as no-tillage, that can enhance services may limit yields. Moving forward, agricultural must reduce trade-offs between Soil functional zone management (SFZM) novel strategy developing sustainable attempts to integrate the...
Since the mid-20th century, crop breeding has driven unprecedented yield gains. Breeders generally select for broadly- and reliably-performing varieties that display little genotype-by-environment interaction (GxE). In contrast, ecological theory predicts across environments vary spatially or temporally, most productive population will be a mixture of narrowly adapted specialists. We quantified patterns broad narrow adaptation in modern, commercial maize (Zea mays L.) hybrids planted 216...
Abstract Soil C status is acritical component of greenhouse gas mitigation efforts, and supports food security through affecting crop growth management. In much the world, laboratory‐based measures soil are expensive logistically challenging, whereas map‐based predictions generated at continental scale (e.g., African Information Service [AfSIS]; www.soilgrids.org ) may be unreliable management‐relevant, policy‐relevant, field, regional scales. We test whether an USD 350, open source, field...
ABSTRACT Increasingly, funding agencies are investing in integrated and transdisciplinary research to tackle “grand challenge” priority areas, critical for sustaining agriculture protecting the environment. Coordinating multidisciplinary teams capable of addressing these however, presents its own unique set challenges, ranging from bridging across multiple disciplinary perspectives achieve common questions methods facilitating engagement holistic integrative thinking that promotes linkages...
The importance of corn production to the midwestern United States cannot be overestimated.However, high requires nitrogen fertilization, which carries costs environmental services such as water quality.Therefore, a trade-off exists between yield and quality.We used Groundwater Vulnerability Assessment for Shallow depths Crop Environment Resource Synthesis-Maize models investigate nature this while testing Simple Analytic Framework trade-offs featured in Special Feature.First, we estimated...
Abstract Climate change is threatening the status quo of agricultural production globally. Perennial cropping systems could be a useful strategy to adapt agriculture changing climate. Current and future perennial row crop have many varied applications these can respond differently than annuals challenges resulting from climate change, such as shifting ranges plant, pathogen, animal species more erratic weather patterns. To capitalize on attributes that assist in our ability world, it...
Abstract Diversification of agroecological systems to enhance agrobiodiversity is likely be critical advancing environmental, economic, and social sustainability agriculture. Temperate-zone that are currently organized for production summer-annual crops can diversified by integration fallow-season perennial crops. Integration such improve these systems, with minimal interference current agricultural production. Importantly, provide feedstocks a wide range new bio-products forming bioeconomy,...
Zonal tillage (e.g. ridge tillage, RT) separates management of row and inter-row positions, while non-zonal chisel plough, CP) applies uniformly across a field. This may have large effects on soil hydrothermal properties, affecting processes crop development. We examined the RT versus CP conditions under maize (Zea mays L.) at four sites spanning US Corn Belt over two growing seasons (2012–2013). also investigated whether RT, as result changes in conditions, could stimulate greater nitrogen...

Abstract Agriculture is a designed system with the largest areal footprint of any human activity. In some cases, designs within agriculture emerged over thousands years, such as use rows for spatial organization crops. other were deliberately chosen and implemented decades, during Green Revolution. Currently, much work in agricultural sciences focuses on evaluating that could improve agriculture's sustainability. However, approaches to design are diverse fragmented, relying individual...
Increasing soil organic carbon (SOC) stocks is increasingly targeted as a key strategy in climate change mitigation and improved ecosystem resiliency. Agricultural land, dominant global land use, provides substantial challenges opportunities for sequestration. Despite this, estimates of sequestration potential often exclude agricultural are coarse regions the Global South. To address these discrepancies improve estimates, we develop hybrid, data-augmented database approach to better estimate...
Abstract Selection during plant domestication and improvement often decreases genetic variation, including variation that confers adaptation to local conditions. We report spatial temporal in fitness (seed yield), adaptation, segregating within three races of common bean ( Phaseolus vulgaris L.) with differing histories diversities. Three‐hundred twenty‐seven genotypes had seed yield measured at subsets 70 sites across North America between 1981 2015, as part the Cooperative Dry Bean Nursery...
Soil microbial communities are difficult to measure and critical soil processes. The bulk microbiome is highly diverse spatially heterogeneous, which can make it detect monitor the responses of differences or changes in management, such as different crop rotations agricultural research. Sampling a subset actively growing microbes should promote monitoring how respond management by reducing variation contributed high spatial temporal heterogeneity less active microbes. We tested an in-growth...
With the increasing emphasis on machine learning and artificial intelligence to drive knowledge discovery in agricultural sciences, spatial internet of things (IoT) technologies have become increasingly important for collecting real-time, high resolution data these models. However, managing large fleets devices while maintaining quality remains an ongoing challenge as scientists iterate from prototype mature end-to-end applications. Here, we provide a set case studies using framework...
