In addition to their value as cereal grains, wheat (Triticum aestivum L.) and triticale (× Triticosecale Wittmack) are important cool-season annual forages and cover crops. Yearling steer (Bos taurus) performance was compared in the spring following autumn establishment as for age cover crops after soybean [Glycine max (L.) Merr.] grain harvest. Replicated pastures (0.4 ha) were no-till seeded in three consecutive years into soybean stubble in autumn, fertilized, and grazed the following spring near Ithaca, Nebraska, USA. Each pasture (n = 3) was continuously stocked in spring with four yearling steers (380 ± 38 kg) for …
Regenerative Farming Practices: How Much Carbon Do They Sequester?, Andrew M. Havens
Regenerative Farming Practices: How Much Carbon Do They Sequester?, Andrew M. Havens
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Along with the recent rise of voluntary carbon markets comes potential carbon credit producers seeking reliable information on how much carbon they can expect to sequester. In this thesis a distribution of expected sequestration outcomes is constructed using cost-benefit analysis and data gathered from agronomic experiments and land-grant university crop budgets for cover crops and no-till practices. The inverse cumulative distribution of carbon sequestration outcomes from adopting a regenerative agricultural practice is visualized and the net social benefit of paying farmers to produce carbon credits is estimated. Results show that on average there is between $29.02 and $37.20 of social …

Cover crops can mitigate soil degradation and nutrient loss and can be used to achieve continuous living cover in cropping systems, although their adoption in the Western Corn Belt of the United States remains low. It is increasingly recognized that cover crop integration into corn (Zea mays L.)-based crop rotations is complex, requiring site and operation specific management. In this review, we compared on-farm, farmer-led field scale trials to researcher-led trials carried out in small plots on University of Nebraska-Lincoln experiment stations. Although there is a range of cover crop research conducted in the state, there is no …
Agricultural Carbon Markets: How Could They Work?, Andrew Havens
Agricultural Carbon Markets: How Could They Work?, Andrew Havens
Honors Theses
The resurgence of voluntary markets in which consumers can purchase carbon credits generated by agricultural carbon sequestration has brought up many questions for farmers looking to potentially enter the market. Past carbon markets, such as the Chicago Climate Exchange, ended when a recession hit, causing demand for credits to swiftly decline. How can modern voluntary markets face these challenges along with new ones and be successful? This research paper, completed as an undergraduate thesis project at the University of Nebraska-Lincoln, examines the economic and scientific factors behind soil carbon sequestration credits. An extended literature review combined with estimation of a …
The Cover Crop Seed Industry: An Indiana Case Study, John C. Tyndall, Adriana Valcu-Lisman, Melanie Bogert, Abigail Zobrodsky
The Cover Crop Seed Industry: An Indiana Case Study, John C. Tyndall, Adriana Valcu-Lisman, Melanie Bogert, Abigail Zobrodsky
Journal of Applied Farm Economics
Winter cover crops are plants used to protect soils during the period between the harvest and establishment of cash crops such as corn and soybeans, effectively providing farm fields with perennial cover. The total cost of cover crops varies considerably from site to site and year to year, yet the single costliest aspect of using cover crops is the cost of seed. Seed cost also tends to be the most volatile component of the cost of cover crop use, subject to complex supply dynamics associated with producing viable seed, storage capacity, and unpredictable regional demand. We conducted a survey of …
The Role Of Farmer Heterogeneity In Nutrient Management: A Farm-Level Analysis, Hua Wang, Naveen Adusumilli, Daniel Fromme, Keith Shannon
The Role Of Farmer Heterogeneity In Nutrient Management: A Farm-Level Analysis, Hua Wang, Naveen Adusumilli, Daniel Fromme, Keith Shannon
Journal of Applied Farm Economics
Understanding farmer heterogeneity regarding nutrient management decisions is crucial for the success of any nonpoint source pollution prevention programs. Data from a farm- level experiment of cover crops in corn production were used in the Stochastic Efficiency with Respect to a Function framework to examine preference for nitrogen strategies over a range of risk aversion levels. We show the highest net return and certainty equivalent to the consideration of N supplied by cover crops. The results provide insights into policy discussions about the level of conservation incentives and plans that offer solutions to mitigate nonpoint source pollution.
Annual Net Returns To Cover Crops In Iowa, Alejandro Plastina, Fangge Liu, Wendiam Sawadgo, Fernando E. Miguez, Sarah Carlson, Guillermo Marcillo
Annual Net Returns To Cover Crops In Iowa, Alejandro Plastina, Fangge Liu, Wendiam Sawadgo, Fernando E. Miguez, Sarah Carlson, Guillermo Marcillo
Journal of Applied Farm Economics
Despite the active promotion of cover crops as a key conservation practice, their adoption is very limited. We developed a series of partial budgets based on a statewide survey of Iowa farmers to evaluate the changes in net returns resulting from the incorporation of cover crops into a corn or soybean production system. The average net returns to cover crop use for farmers who did not use cover crops for grazing livestock or forage were consistently negative across different planting and termination methods, tillage practices, and experience levels. Only farmers who used cover crops for grazing livestock or forage and …
