Soybean Aphid-Resistant Soybean Varieties For Iowa, Michael T. Mccarville, Erin W. Hodgson, Matthew E. O'Neal Nov 2012

Soybean Aphid-Resistant Soybean Varieties For Iowa, Michael T. Mccarville, Erin W. Hodgson, Matthew E. O'Neal

Agriculture and Environment Extension Publications

The soybean aphid is an economically damaging pest that has caused yield loss in parts of Iowa in seven of the past twelve years. This publication looks at how to choose, when to use, and the effects of aphid-resistant varieties.


Current Challenges In Managing Corn Rootworm, Erin W. Hodgson, Aaron J. Gassmann Nov 2012

Current Challenges In Managing Corn Rootworm, Erin W. Hodgson, Aaron J. Gassmann

Agriculture and Environment Extension Publications

Corn rootworm is a major pest of corn in the United States. In the last decade, Iowa farmers have seen many changes for managing corn rootworm. With the commercial release of transgenic Bt-rootworm corn in 2003, many farmers reduced or eliminated soil-applied insecticides to manage larvae. Western corn rootworm is adapting to transgenic technologies throughout the Corn Belt. Some continuous cornfields have larvae that can now survive at high numbers and cause severe root injury to Bt corn. We encourage farmers to use multiple strategies to protect corn.

Farm Energy: Conserving Energy By Using Localized Heating In Swine Housing, Jay D. Harmon, Hongwei Xin, Dana Petersen Jun 2012

Farm Energy: Conserving Energy By Using Localized Heating In Swine Housing, Jay D. Harmon, Hongwei Xin, Dana Petersen

Agriculture and Environment Extension Publications

Using heat lamps, heat mats, and brooders for localized heating can improve energy efficiency in swine housing. Learn about small adjustments and management considerations for implementing localized heating.


Farm Energy: Energy Consumption For Row Crop Production, H. Mark Hanna, John E. Sawyer, Dana Petersen Jun 2012

Farm Energy: Energy Consumption For Row Crop Production, H. Mark Hanna, John E. Sawyer, Dana Petersen

Agriculture and Environment Extension Publications

This publication provides an overview of farm energy use related to corn and soybean production in Iowa. Three areas of row crop production--field operations, fertilizer and pesticide application, and artificial drying--are used to illustrate on-farm energy consumption.


Farm Energy: Energy Considerations For Low-Temperature Grain Drying, Shawn C. Shouse, H. Mark Hanna, Dana Petersen May 2012

Farm Energy: Energy Considerations For Low-Temperature Grain Drying, Shawn C. Shouse, H. Mark Hanna, Dana Petersen

Agriculture and Environment Extension Publications

Harvested corn often requires artificial drying to lower moisture content for safe storage. Learn about energy considerations for drying corn with natural-air or low-temperature systems.


Farm Energy: Managing Swine Ventilation Controller Settings To Save Energy, Jay D. Harmon, Michael C. Brumm, Dana Petersen Mar 2012

Farm Energy: Managing Swine Ventilation Controller Settings To Save Energy, Jay D. Harmon, Michael C. Brumm, Dana Petersen

Agriculture and Environment Extension Publications

Ventilation is by far the largest source of heating energy loss in swine facilities. To maintain air quality, it is essential to provide proper minimum ventilation without losing excessive energy from the building. Learn how modern controllers interlock equipment operation to avoid conflicts that waste energy.
