Book excerpt: Soil health indicators are commonly used by researchers to understand how various soil properties are functioning. However, many new indicators have not been applied on working farm conditions and it is not well understood how these novel indicators may be useful to farmers in their management decision-making. This research took an integrated approach combining social science methods and biophysical soil testing to understand the use and value of soil health indicators to farmers in Ohio. A total of 19 soil health parameters were measured and reported back to farmers to discuss how these data could inform their future management decisions and to understand which indicators are most useful to farmers. Interviews were conducted with 20 row crop farmers to gather their insights on the utility of soil health indicators, as well as their management decisions following the 2019 growing season. Ultimately, the research evaluated how soil health indicators varied across selected fields the farmer deemed best and most challenging. This research also assessed which indicators aligned best with farmer perceptions of the soil health data and if the soil health indicators influenced adoption of new management practices among farmers. Findings from the research indicate that biological soil health indicators such as soil protein, respiration (MinC), and permanganate oxidizable carbon (POXC) were able to distinguish between best and most challenging field, were more sensitive indicators than others, and were most aligned with farmer perceptions of their fields. Additionally, this study found that while farmers found many biological indicators insightful, they did not provide sufficient information to alter any change in management. Overall, this study highlights the importance of interdisciplinary work by integrating social and natural sciences to gain a comprehensive assessment of farmers’ perceptions and practices in relation to agricultural soil health. In doing so, the research addresses a vital issue in Ohio specifically and the Midwest more generally

Book excerpt: Farmer interviews and soil sampling were conducted on 34 farms to explore how farmers' soil health (SH) perceptions, assessments and management practices relate to lab SH measures: the Cornell Soil Health Assessment (CSHA), bio-indicator Folsomia candida growth, and phospholipid fatty acid analysis (PLFA). Farmers emphasized biological and production-based SH aspects but neglected ecological considerations, and their SH assessments agreed most strongly with CSHA assessments of nutrients, available water capacity and biological activity. F. candida growth did not differentiate between soils nor reflect CSHA results. Manure application and perennial/mixed rotations were positively correlated with water-stable aggregates, soil respiration, and all PLFA microbial groups, while tillage and simplified grain/vegetable rotations were correlated with P, Cu, Al, sand and the predator:prey ratio. Results show promise for integrating CSHA and PLFA to improve SH assessment, but to affect farmers' SH management decisions, the SH concept and testing must make sense within farmers' worldview.

This book was released on 2016 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The west-central region of Ohio is one of the most productive agricultural regions of the state and has notable economic importance. Past and projected climatic changes bring a significant amount of variability into the future productivity of this specific region and place an importance on protecting soil resources. The objectives of this study were to examine the effects of common management practices, including Best Management Practices (BMPs), in West-Central Ohio on key soil properties supporting overall soil quality, the productivity of soils under such practices, and the feasibility of using the Soil Management and Assessment Framework (SMAF) to evaluate soil quality in the region. On-farm study sites were established representing examples of conventional tillage (CT), no-till (NT), no-till with manure application (NT-M), and no-till with cover crops (NT-CC) common to the region. Significant differences were found among all measured soil properties, except available water capacity (AWC), steady state infiltration, and water stable aggregation (WSA). Despite this, evidence was found to support improved aggregate stability under cover crops. The NT and NT-CC sites were shown to have increased large pore formation, mean weight diameter (MWD), and saturated hydraulic conductivity (Ks) even though they possessed higher bulk density in the upper soil profile. The distribution and concentration of soil organic carbon (SOC) were both affected under the BMPs studied. Particularly at the NT site, an increase in the SOC concentration and stock was seen in the 0-10 cm depth but below this point the CT site had equal to greater SOC concentrations and stock when compared to the no-till sites. The NT-CC site was found to have the lowest overall SOC stock but conclusions concerning the results from the lower soil depths were limited due to variability within the subsoil or past management at the NT-CC site. Differences were found in yield and calculated harvest index (HI) for both corn and soybean crops. Corn production and HI were found to be significantly higher at the NT-CC site when compared to all other sites and the NT and NT-M sites were found to produce the highest soybean yields and HI. Significant differences were found among SOC, MBC, and pH indicator scores but not among the total SQI scores. No significant correlation was found between yield and total SQI scores, but the bulk density indicator was found to be most highly correlated with total SQI and relative yields. In addition, un-scored bulk density data were positively correlated with relative yields, suggesting that the SMAF unfairly penalized sites with elevated bulk density. The improvements in soil properties observed within the upper soil profile, at the NT-CC and NT sites, are suspected to play an important role in maintaining soil quality under variable and changing climate conditions. It was concluded, due to the inaccurate evaluation of bulk density and the fact that no correlation between total SQI scores and relative yields was produced, the broadly designed SMAF was not able to applicably evaluate soil quality in the specific region of West-Central Ohio.

Book excerpt: Much of the current analysis on agricultural productivity is hampered by the lack of consistent, high quality data on soil health and how it is changing under past and current management. Historically, plot-level statistics derived from household surveys have relied on subjective farmer assessments of soil quality or, more recently, publicly available geospatial data. The Living Standards Measurement Study of the World Bank implemented a methodological study in Ethiopia, which resulted in an unprecedented data set encompassing a series of subjective indicators of soil quality as well as spectral soil analysis results on plot-specific soil samples for 1,677 households. The goals of the study, which was completed in partnership with the World Agroforestry Centre and the Central Statistical Agency of Ethiopia, were twofold: (1) evaluate the feasibility of integrating a soil survey into household socioeconomic data collection operations, and (2) evaluate local knowledge of farmers in assessing their soil quality. Although a costlier method than subjective assessment, the integration of spectral soil analysis in household surveys has potential for scale-up. In this study, the first large scale study of its kind, enumerators spent approximately 40 minutes per plot collecting soil samples, not a particularly prohibitive figure given the proper timeline and budget. The correlation between subjective indicators of soil quality and key soil properties, such as organic carbon, is weak at best. Evidence suggests that farmers are better able to distinguish between soil qualities in areas with greater variation in soil properties. Descriptive analysis shows that geospatial data, while positively correlated with laboratory results and offering significant improvements over subject assessment, fail to capture the level of variation observed on the ground. The results of this study give promise that soil spectroscopy could be introduced into household panel surveys in smallholder agricultural contexts, such as Ethiopia, as a rapid and cost-effective soil analysis technique with valuable outcomes. Reductions in uncertainties in assessing soil quality and, hence, improvements in smallholder agricultural statistics, enable better decision-making.

Book excerpt: Soil Acidity and Plant Growth emerged from concerns over increasing acidification of soils under improved pastures over wide areas of southern Australia. While the book has its origin in the problems of acidification of Australian soils under pastures, the authors examine soil acidity within a much broader framework, making their views relevant to all agricultural and natural ecosystems on acid soils. The book's first two chapters discuss the chemistry of soil acidity and the ecological processes leading to it. This is followed by separate chapters on biological responses to soil acidity, covering mineralization of soil nitrogen, incidence of plant diseases, plant mycorrhizal associations, symbiotic nitrogen fixation in legumes, and genetic variability in plant response to toxicities. The remaining chapters focus on the correction of soil acidity problems by liming. These include studies on the rates of application and effectiveness of liming materials; and the development and use of computer modelling procedures to help researchers identify the effects and interactions of soil pH on component processes and to provide assistance to farmers in the management of long-term subterranean clover pastures.

Book excerpt: During the mid-1960s, India came to the brink of an acute food crisis in the midst of heavy dependence on food imports. A period of rapid agricultural modernization that followed, known as Green Revolution, transformed India from a net importer of food into an exporter. Although an appropriate response for abating the impending starvation, the Green Revolution inflicted several unintended consequences. For example, regulatory structure and fertilizer subsidies for urea that were designed to stimulate growth instead resulted in a lock-in, which in turn incentivized vast over-fertilization across the country. Today, this is a well-recognized problem, and the Government of India has announced policies and schemes such as the National Soil Health Card Scheme to increase knowledge of soil condition and curb fertilizer use. In reality, however, the current need for information on soil health far exceeds the capacity for soil testing, highlighting the need for a radical approach to meeting this policy objective. This project, undertaken in collaboration with MIT Mechanical Engineering, takes a two-part approach to addressing this problem, with the design of a point-of-use soil testing sensor and an accompanying recommendation generation engine. This thesis presents the design of the latter based upon the answer to the following question: what constitutes an actionable information for resource constrained farmers? To answer it, we use a mixed methodology approach comprising (i) a combination of stakeholder interviews and design workshops to elicit user needs, and (ii) controlled experimentation with over 200 farmers covering an entire village to measure the actionability of information in soil health recommendations. The results of the analysis of experimental data reveal that the actionability of recommendations varies significantly within the population of farmers tested, and can be attributed to the level of information provided, the environment in which a farmer receives a recommendation, gender, and education level. Consequently, an effective point-of-use diagnostic system must adjust for these factors in order to maintain high actionability. To that end, we then use the experimental results to design a recommendation generation engine, the core of which is a soil health database that maximizes the actionability of information for a resource constrained farmer.

This book was released on 2021 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintaining SH (SH) is critical for sustainable field crop production. The first step to understanding drivers is evaluating the effects of climate, soil edaphic properties, and management practices from an on-farm study across a regional scale on SH. Thus, I integrated on-farm research, farmer participatory approach, and statistical analysis to understand the SH drivers in the United States and Malawi. In summary, I assessed the SH indicators through two perspectives with various statistical models: 1) understand various viewpoints on SH assessment; and 2) integrating Bayesian statistical analysis, hierarchical cluster analysis, and principal component analysis to determine the drivers of SH and yield in Michigan, U.S. and the Central and Southern region of Malawi.SH is assessed through soil physical, chemical, and biological properties. However, researchers used various minimum laboratory SH dataset, resulting in the inconsistency in research studies. On-site SH evaluations recommended by extension educators were not always adopted by farmers. In this chapter, we compared the common indicators in laboratory analysis and on-farm evaluation through literature review and used a Likert Scale to understand farmers' views in Michigan. Maintaining SH (SH) is critical for sustainable field crop production. The first step to understanding drivers is evaluating the effects of climate, soil edaphic properties, and management practices from an on-farm study across a regional scale on SH. Thus, the farmer participatory approach and statistical analysis were integrated to understand the SH drivers in the United States and Malawi. In summary, SH indicators were assessed in this study through two perspectives with various statistical models: 1) understand various viewpoints on SH assessment; and 2) integrating Bayesian statistical analysis, hierarchical cluster analysis, and principal component analysis to determine the drivers of SH and yield in Michigan, U.S. and the Central and Southern region of Malawi.SH is assessed through soil physical, chemical, and biological properties. However, researchers used various minimum laboratory SH datasets, resulting in inconsistency in research studies. On-site SH evaluations recommended by extension educators were not always adopted by farmers. In Chapter 1, a Likert study was employed to understand farmers' views of common soil health indicators in Michigan. The results showed that the concept of SH assessment should be consistent and clear in research studies and extension education materials.Soil degradation is the most challenging yield-limiting factor in Sub-Saharan Africa. Without the information of current soil carbon status, farmers do not have sufficient information for deciding the appropriate management practice. Malawi's rain-fed maize system is a representation of the rain-fed maize cropping system in East Africa. In Chapter 2, soil analyses were conducted on 1108 focal plots in Central and Southern Malawi to better understand the current total and labile soil carbon status. Bayesian statistical approaches were employed to evaluate environmental and management drivers for soil total and labile carbon on Malawi smallholder fields. Overall, clay content and the vegetative cover are positive drivers for soil total and labile carbon.To better understand the SH across the regional scale in the Midwest United States, an on-farm study of 242 focal plots was conducted in Michigan. In Chapter 3, participatory monitoring and Bayesian linear regression models were used to investigate the impact of various drivers on SH indicators under a range of conditions in the state of Michigan. Location effects were observed, with each of the three regions differing in their climate, soil edaphic properties, and management practices. Overall, climate and soil edaphic properties were the dominant drivers of SH, management practices, which also play a critical role, especially in enhancing soil biological indicators.When evaluating SH, multivariate statistical analysis is generally used due to the inherent correlation among the variables. In Chapter 4, hierarchical cluster analysis and principal component analysis were adopted to evaluate the 1) interrelationship of various SH indicators; and 2) drivers of the variation across focal plots and local clusters. Besides the high correlated SH indicators, independent variables provide valuable information. The key determinant of SH indicators is geographical clusters. Farmers' management practices should be site-specific and goal-oriented considering the tradeoff between residual nitrogen and soybean yield.

Available in PDF, EPUB and Kindle. Book excerpt: In order to build resilience to climate change, increase long-term sustainability of farming operations and decrease the impacts of our current food production system, the concept of soil health has received renewed attention in recent years. Soil is a vital natural resource with the ability to be degraded. Managing for soil health can not only create more sustainable and productive farming systems, but also increase profitability over longer time scales. Benefits of managing for soil health can include decreased soil erosion, more efficient fertilizer use and higher water holding capacity. Despite the benefits of managing for soil health, there is much confusion regarding how to measure it. Traditional soil tests allow farmers to chemically evaluate soils for nutrients, while newer, more integrative soil health testing combines chemical, biological and physical elements to make a more complete analysis. Farmers in northern Idaho and elsewhere are lacking knowledge of how to select appropriate soil health tests, how the results compare to traditional soil fertility tests, and how to interpret and apply the results. This may be especially true for organic growers, since soil health tests have largely been developed and researched on conventionally managed farmground. This project aims to further increase resources regarding testing for soil health and fertility by 1) assessing the relationships among results from traditional soil fertility tests and those of lesser known soil health tests, 2) conducting a survey to determine current soil testing practices in Idaho and barriers for adoption. The first chapter of this thesis includes research comparing traditional and lesser studied soil health tests including the Haney Soil Health Test (HSHT) and permanganate oxidizable carbon (POxC) at three organic farms in northern Idaho. Three fertilizer application rates were created utilizing plant available nitrogen (N) extracted with 2M KCl (standard fertility test) and H3A (a component of the HSHT). These treatments (KCl and H3A), were compared to a "farmer standard" which simulated how farmers would apply fertilizer without soil testing. Inorganic N extracted by KCl and H3A were comparable (R=0.90, p

Book excerpt: Thousands of years of poor farming and ranching practices—and, especially, modern industrial agriculture—have led to the loss of up to 80 percent of carbon from the world’s soils. That carbon is now floating in the atmosphere, and even if we stopped using fossil fuels today, it would continue warming the planet. In The Soil Will Save Us, journalist and bestselling author Kristin Ohlson makes an elegantly argued, passionate case for "our great green hope"—a way in which we can not only heal the land but also turn atmospheric carbon into beneficial soil carbon—and potentially reverse global warming. As the granddaughter of farmers and the daughter of avid gardeners, Ohlson has long had an appreciation for the soil. A chance conversation with a local chef led her to the crossroads of science, farming, food, and environmentalism and the discovery of the only significant way to remove carbon dioxide from the air—an ecological approach that tends not only to plants and animals but also to the vast population of underground microorganisms that fix carbon in the soil. Ohlson introduces the visionaries—scientists, farmers, ranchers, and landscapers—who are figuring out in the lab and on the ground how to build healthy soil, which solves myriad problems: drought, erosion, air and water pollution, and food quality, as well as climate change. Her discoveries and vivid storytelling will revolutionize the way we think about our food, our landscapes, our plants, and our relationship to Earth.

Book excerpt: “Soil Health and Climate Change” presents a comprehensive overview of the concept of soil health, including the significance of key soil attributes and management of soil health in conventional and emerging land use systems in the context of climate change. Starting with a review of the physical, chemical and biological indicators of soil health and their significance for monitoring the impacts of climate change, this book then focuses on describing the role of soil structure, pH, organic matter, nitrogen, respiration and biota in sustaining the basic functions of soil ecosystems, and their anticipated responses to climate change. Further topics include the management of cropping, pastoral, and forestry systems, and rehabilitated mine sites, with a focus on mitigation of and adaptation to climate change impacts. Finally, the opportunities and potential risks of organic farming, biochar and bioenergy systems, and their ability to sustain and even enhance soil health, are discussed.
