Harvesting fertilized rye (Secale cereale L.) cover crop has been suggested as a method to increase producer revenue and biofuel feedstock production, but drainage N loss impacts are currently unknown. Using the tested Root Zone Water Quality Model (RZWQM) across several N rates, spring application of 120 kg N ha^-1 prior to winter rye harvest reduced drainage N loss by 54% compared with no cover crop and by 18% compared with planted rye that was neither fertilized nor harvested. Estimates of producer revenue and net energy were also positive, with 8.3 Mg ha^-1 of harvested rye biomass. …

Crowdsourcing Image Analysis For Plant Phenomics To Generate Ground Truth Data For Machine Learning, Naihui Zhou, Zachary D. Siegel, Scott Zarecor, Nigel Lee, Darwin A. Campbell, Carson M.

The accuracy of machine learning tasks critically depends on high quality ground truth data. Therefore, in many cases, producing good ground truth data typically involves trained professionals; however, this can be costly in time, effort, and money. Here we explore the use of crowdsourcing to generate a large number of training data of good quality. We explore an image analysis task involving the segmentation of corn tassels from images taken in a field setting. We investigate the accuracy, speed and other quality metrics when this task is performed by students for academic credit, Amazon MTurk workers, and Master Amazon MTurk …

Living Seeds Of History: The John Stokes And Mary's Gardens Exhibit, Stephanie Shreffler, Kayla Harris

Kayla Harris

This panel describes how the University of Dayton planned and carried out an exhibit on the John Stokes and Mary’s Gardens archival collection, featuring a garden inside the library. A “Mary garden” is a garden filled with flowers named for Mary.

The panel describes the content of the collection and how the exhibit was originally conceived; the exhibit design and programming; and the challenges faced during the planning process.

The exhibit provided a way for the Libraries to promote an archival collection that not only closely connected with the University’s mission as a Catholic institution, but also provided new opportunities …

This conference was really an outgrowth of an earlier conference on Structural Changes in Commercial Agriculture (CAED Report 24) held in Chicago, April 12-14, 1965. While the earlier conference emphasized structural changes in the agricultural industry and their implications for education and extension, the 1967 conference focused on research.

Delayed Planting, Prevented Planting And Replanting Crop Insurance Coverage, Steven D. Johnson, William M. Edwards

William Edwards

The frequent rains that have soaked Iowa this year have left many corn and soybean fields unplanted or with flooded areas. Many producers are wondering what options they have under their multiple peril crop insurance (MPCI) policies. In Iowa, the crop insurance “late planting period” for corn begins on June 1. Corn can still be planted after this date, but the insurance guarantee on those acres is reduced by 1 percent per day until the acres are planted. Corn acres planted after June 25 will receive insurance coverage equal to 60 percent of their original guarantee. Producers should keep accurate …

Flood Damaged Crops, Crop Insurance Payments And Lease Contracts, William M. Edwards

William Edwards

Some Iowa corn and soybean producers are facing substantial if not complete crop losses due to flooding. In particular, many acres of crops in the Missouri River Valley have been under water for a month or more this year. Fortunately, nearly 90 percent of Iowa’s corn and soybean acres are protected by multiple peril crop insurance.

Farmland Rental Rates Show Continued Strength In 2012, William M. Edwards, Ann M. Johanns

William Edwards

Anyone who is involved with the rental market for Iowa farmland knows that rental rates have been pushed significantly higher by the favorable corn and soybean prices that farmers have enjoyed since 2010. This trend continued in 2012.

Nearly 90 percent of the corn and soybean acres in Iowa are covered by multiple peril crop insurance. Drought damage is an insurable loss under these policies. Producers should consult with their crop insurance agents before harvesting or destroying any drought-damaged crops, however.

Important Crop Insurance Dates, William M. Edwards

William Edwards

Even the best crop insurance plan is of little use if the right information is not collected and submitted on time. Likewise, if certain actions are not completed by the necessary date, producers may not receive full benefit from the risk protection that they have selected.

Early Planted Acres May Lose Replant Insurance, William M. Edwards

William Edwards

Unusually warm and dry weather has allowed crop producers to start spring field work earlier than can be remembered by most people. Getting an early start on tillage and planting reduces the risk of getting behind schedule later if an extended period of rainy weather occurs, but it also has its risks. The Risk Management Agency (USDA) has some specific rules about early planted crops with regard to crop insurance coverage. For each insurable crop RMA has set an “early planting date.” The earliest planting dates allowed for counties in the state of Iowa are April 11 for corn and …

Community Involvement To Address A Long-Standing Invasive Species Problem: Aspects Of Civic Ecology In Practice, Rebecca W. Dolan, Kelly Harris, Mark Adler

Rebecca W. Dolan

Invasive non-native species (INS) are found in every city around the globe, but their impacts in urban settings as biological agents of visual pollution that block views of natural landscapes and disconnect citizens from nature are not as often addressed as comprehensively as their impacts in natural areas or agricultural settings. The multiple impacts of INS in cities make them ideal candidates for aspects of Civic Ecology Practice, where local environmental stewardship action is taken to enhance green infrastructure and community well-being in urban and other human-dominated systems. We present details of a community driven program focused on removal of …
