Book excerpt: Soil is the foundation for human civilization - it is the literal foundation of our homes, the source of raw materials, a filter and storage system for the water we drink, a medium for plant growth, and a habitat for many organisms. Keeping the soils of our planet healthy to carry out these functions is incredibly important. In agriculture, there is a building movement to study and improve soil health across the landscape, of which this research is a small part. This body of research addresses several areas within soil health; how we define and test for healthy soil, practices that may help build healthier soil, and some of the practical challenges of managing for soil health. We specifically focused on annual row crop systems in the North Central US region, and in particular soybean production. First, we focused on a few practical soil health tests that could be adopted by farmers - linking these measurements to both historical management and soybean yield. This study was a community-science project that relied on the help of Wisconsin soybean farmers to sample their fields and relay management information. The results of this study will help direct future research and identified crop rotation as a key area for soil health improvement. Next, we examined some common production practices related to building soil health and their effects on crop yield using long-term crop rotation studies. We looked at the effects of tillage, crop rotation, and foliar fungicide use on corn and soybean yield, and the legacy effect of the latter two of these treatments on soil fungal populations. Microbial communities carry out critical functions in soil, so it is important to understand how human activity shapes their populations. Finally, another long-term rotation study was used to look at the feasibility and yield effects of establishing cover crops, a key soil health practice, in annual row crop systems in Wisconsin. Overall, this work identifies avenues for both measuring and improving soil health in North Central US soybean.

Available in PDF, EPUB and Kindle. Book excerpt: Global value chains (GVCs) powered the surge of international trade after 1990 and now account for almost half of all trade. This shift enabled an unprecedented economic convergence: poor countries grew rapidly and began to catch up with richer countries. Since the 2008 global financial crisis, however, the growth of trade has been sluggish and the expansion of GVCs has stalled. Meanwhile, serious threats have emerged to the model of trade-led growth. New technologies could draw production closer to the consumer and reduce the demand for labor. And trade conflicts among large countries could lead to a retrenchment or a segmentation of GVCs. World Development Report 2020: Trading for Development in the Age of Global Value Chains examines whether there is still a path to development through GVCs and trade. It concludes that technological change is, at this stage, more a boon than a curse. GVCs can continue to boost growth, create better jobs, and reduce poverty provided that developing countries implement deeper reforms to promote GVC participation; industrial countries pursue open, predictable policies; and all countries revive multilateral cooperation.

Available in PDF, EPUB and Kindle. Book excerpt: Regularly evaluating best management practices for soybean is important to maintaining agronomic crop production as the climate and seed varieties change over time. Many phosphorous and potassium fertilizer recommendations in the North Central US are based on the build-maintain framework and were developed in 1970s and 80s and are due to be reevaluated. To estimate the yield-maximizing soil test potassium level (YMK) under current growing conditions, nutrient management records and yield maps from southern WI were analyzed via quadratic quantile regression to estimate both overall YMK and determine if YMK varied across the study space. The overall YMK was 76 ppm, and lower buffer pH and organic matter levels were associated with higher YMK. Some fertilizer recommendations include leaf tissue K concentrations in addition to soil test K levels. Results of a 2021 on-farm trial indicate that the critical K concentration in soybean leaf tissue is 2.04%. The relationship between K soil test results from Bray-1 extraction and Mehlich-3 extraction for silty loam soils was represented by the linear regression line Bray = 0.77 * Mehlich - 0.75. Management decisions that increase soybean yield are region-specific and vary between planting dates, so larger multi-state research projects are valuable for developing best management practices. In a survey study of soybean farmers in ten North Central US states, late-planted fields had higher yields associated with tillage and using both a PRE and POST herbicide application. Early-planted fields had higher yields associated with artificial drainage, insecticide seed treatment, and lower seeding rates. Less variation between sites was observed in a small-plot study of foliar fertilizers across 46 site-years in 16 eastern US states. Foliar fertilizers did not increase soybean yield in the absence of visual symptoms of nutrient deficiency. In multi-state and on-farm research, efficient processing of yield maps represents a research bottleneck. A new R package, cleanRfield, allows for more efficient processing of yield maps. Together, these projects represent ways for multistate and multidisciplinary teams to leverage technology and improve best management practices for soybean production.
