This book is dedicated to two of the most important issues in agriculture: cover crops and crop yield. A cover crop is a crop planted in a garden to protect the soil from erosion and to improve the soil by adding organic matter. In agriculture, crop yield (also known as "agricultural output") is not only a measure of the yield of cereal per unit area of land under cultivation, it is also the seed generation of the plant itself, i.e. one grain of wheat produces a stalk yielding three grain, or 1:3. This book reviews the effect of cover crops and how the latter might lead to the improved soil and environmental quality if crop yields are sustained.

This book will not serve as the "encyclopedia of cover crop management," but it’s close. The benefits of a wide range of individual cover crops and blends/mixes for specific agronomic crop rotations and geographic locations are included. Descriptions, photographs, and illustrations show how cover crops look in the field, including plant height, leaf architecture, and rooting patterns. Long term benefits are described for soil health, soil structure, water quality, nutrient contributions, soil biodiversity, air quality and climate change. In addition to the "whys" of cover crop use, the book includes details on the "hows:" how to choose cover crops for specific applications and locations; how (and when) to plant; how to manage and maintain the cover for maximum benefit; and how and when to terminate. Planting options include: drilling/planting between rows of an agronomic crop at planting time, or when the crop is short (i.e. corn in early June); "aerial" seeding with an airplane or high-clearance machine shortly before the crop reaches maturity; and drilling/planting immediately after harvest of the agronomic crop. Selected cover crops (blends) can help with pest and disease management. Cover crops are an economic input with an expected return on investment, similar to pesticides and fertilizer. As part of a continuous no-till system, cover crops provide long-term biological, chemical and structural benefits. The resulting increase in soil organic matter means the agronomic crop yields benefit from better water infiltration and water holding capacity, greater availability of nitrogen and other nutrients, deeper rooting, and increased soil microbial activity in the root zone.

What is soil health and why is it so important? In short, healthy soil allows farmers to continue to produce our food safely and inexpensively, so it is vitally important to all of us and generations to come. Cover Cropping in Western Canada provides essential information for farmers who want to increase the fertility of their fields for increased production. While cover cropping is, as the author states, “not a silver bullet,” it is an important part of a whole system approach that can play a central part in bringing agricultural fields renewed health. For those who haven’t considered cover cropping, this easy-to-read reference guide offers basic information about the common issues that impact agricultural land and some strategies to improve its health. For those who are ready to consider cover cropping options, this compact reference guide provides detailed data about sixty-one species that can be planted to fulfill the producer’s goals. To complement goals and species selection, Cover Cropping in Western Canada discusses options for grain farming, benefits of grazing and generating hay and silage, the role cover crops can play in erosion control, nutrient building, nitrogen fixation, weed suppression, and more. Cover Cropping in Western Canada will help producers incorporate cover cropping into their production systems with confidence. The references discussed are observations from Western Canada but can be applied anywhere. Producers will understand how to set goals, pick appropriate species to meet those goals, and create a management plan to effectively integrate cover crops into their rotations. This is a must-have reference for producers who want to increase soil health and to help control greenhouse gas emissions.

Agroecosystem sustainability as a framework for agriculture production systems requires attention to detail to multiple facets of the underlying production system. Production systems must achieve optimal cash crop yields while remaining profitable. Likewise, production practices must be tailored to reduce its environmental footprint. Identifying practices that encourage improved soil physical and chemical properties while maintaining yields have largely been challenging. Cover crops have been an integral part of the conversation regarding practices that can generally improve those properties of soil responsible for overall soil health. Use of winter cereal cover crops (WCCC's) have shown promise as a tool for reducing soil and nutrient runoff, thereby reducing nitrogen (N) and phosphorus (P) nonpoint source pollution in the Upper Mississippi River Basin (UMRB). However, corn-cash crop yield penalties are often incurred following the use of WCCC's such as winter cereal rye (Secale cereal) (WCR), as N is immobilized by cover crop residues in the decomposition processes. Additionally, traditional planting methods of cover crops have resulted in reductions of harvestable populations of corn and soybeans. These problems indicate a necessity for novel cover crop planting methods that reduce the consequential outcomes of implementing traditional cover crop practices. Using a method called "Skipping the corn row" (STCR), otherwise identified as "precision planted" cover crops, we aimed to reduce the cash crop yield-limiting interactions of cover crop residues within the cash crop row. We hypothesized that removing cover crop biomass from the subsequently planted cash crop row (chapter 1) could minimize N immobilization by residues, thereby increasing our subsequent yield potential and economic optimum return to N (EORN). In novel cover crop planting methods preceding soybeans (chapter 3), our hypothesis indicated that mixtures of WCR and crimson clover (Trifolium incarnatum) would impact biomass accumulation of weed communities, while novel measures that allowed for reduced seeding rates would permit competitive soybean yields while reducing input costs for cover crop seed. Chapter 2 focused on interseeding mixtures of WCR and crimson clover, where we hypothesized that residual rates would marginally impact percent cover of WCR and crimson clover mixtures. Our results indicated, in chapter one, that reducing seeding rate by using STCR planting method did indeed drive seed cost savings while improving yield and EORN in comparison to a traditionally planted cover crop. Our results in chapter 3 also indicated reduced seeding rates found in novel planting methods improved the on-farm economics of using cover crops while maintaining healthy soybean yields. Lower-than-average rainfall accumulations later in the growing season coupled with cover crop residues likely influenced soil moisture retention, benefiting the cash crop during the dry spell, helping maintain yields. Interseeding methods, as studied in chapter 2, did not show any significant impact on corn grain yield or yield components. Subsequently, half- and full-rate residual herbicides did not impact percent cover of cover crops. However, use of residual herbicides should be consistent with all herbicide labels and laws, and producers should use label-recommended amounts to maintain maximum efficacy of herbicides and to prevent resistant weed populations. Also, interseeded cover crops failed to successfully establish, resulting in minimal cover crop biomass in later sampling dates.

Agriculture in Kansas and the Great Plains faces many sustainability challenges. Cover cropping is a practice that can affect sustainability by improving soil health parameters in some environments, but more work is needed in the frame of no-till systems in eastern Kansas. Additionally, cash crop yield is an important consideration for production agriculture, but is only reported in less than one-third of soil health studies. Field experiments were conducted on long-term no-till (>10 years) farms in 2014-2017 near Burlington, Hutchinson, and Valley Falls, Kansas. Sites were selected in partnership with local extension, with typical cropping rotations for the area. The objectives of this study were to (i) determine the impact of cover crops on soil health (ii) quantify biomass of established cover crops (iii) quantify yield impacts of cover crops on cash crop yield by comparing single species cover crop (CS), multiple species cover crop (CM), and no cover crop (NC) treatments. In addition, a tillage (T) treatment was included at the Burlington site. Plots were arranged in a randomized complete block design with three replications. Analysis of the soil property data largely found no consistent treatment effects (alpha = 0.05), though sporadic differences were detected. For example, infiltration significantly differed among treatments at the Burlington site in fall 2016, where the T and NC plots had significantly higher rates than the CS and CM plots, but it did not repeat in the 2017 samplings. The Burlington location was the only site to have differences in soil aggregate properties. The aggregates in the tillage plots were getting smaller over time likely from the mechanical breakdown of annual tillage. A significantly smaller mean weight diameter was observed for T as opposed to the other treatments in spring 2016. In 2015 and 2016 the NC treatment also began to show higher proportions of the 0.25mm WSA and less 4.75mm and 2.00mm WSA than the cover crop plots. Very few significant differences were found in the soil biological or chemical parameters, and those that were found lacked repeatability across years. Significantly higher dissolved organic carbon concentrations were observed in the mixed cover crop treatment at the Burlington location for the fall 2017 sampling time, and pH had sporadic instances of significance as well. In conclusion, during the first three years of this project, cover crops have had minimal short-term effects on soil dynamic properties, or cash crop yield, in long-term no-till in eastern Kansas. These results imply that cover crops are likely not a hindrance nor an enhancement to grain corn or soybean yields in eastern Kansas. Additionally, there may be an opportunity for growers to reduce seed costs by planting a single species cover crop as there was no short-term yield or soil health benefit to planting a multi-species mix.
