Conservation

Conservation encompasses many areas - soil, water, and crop considerations all play a part. We offer a variety of practical resources to help you find the answers to your questions.

"How resilient are our lands here in the Midwest? What is our ability to retain productivity if we have another long drought or continual flooding? Will people still be farming in Iowa 1,500 years from now? Or even 200 years from now? The decisions we make today about our natural resources will affect agricultural production 50 years from now." --from the video "The Work of Our Hands"

Cover Crops

Cover crops are a great way to improve soil health. Many Iowa farmers are adding cover crops to their crop rotations so soil stays covered when the fields are not growing other crops. Cover crops also improve soil organic matter and slow water runoff.

Farmers have many questions about incorporating cover crops. Most asked questions include: what kinds of plants can be used, when and how to seed and when and how to terminate. With field days and workshops, Iowa Learning Farms strives to help farmers, and other interested people, find the answers to these questions and more.

Edge-of-Field

Edge-of-field practices play a crucial role in meeting the Iowa Nutrient Reduction Strategy goals of improving water quality through reducing nitrogen and phosphorus in Iowa's water bodies. Edge-of-field practices involve drainage water management, bioreactors, buffers, saturated buffers, denitrifying wetlands, terraces and sediment control.

Relay Intercropping

Relay intercropping is a multi-year, multi-species cropping system that allows for 3 harvestable crops (small grain, soybean, corn) in 2 years.

Field Day Toolkit

These toolkits are the product of Iowa Learning Farms’ many years of planning and hosting field day events across the state of Iowa, as well as our newer Conservation On Tap gatherings. While ILF utilizes many different outreach approaches, the importance of farmer-to-farmer interactions cannot be overstated. Field days do matter!

Webinar Toolkit

Iowa Learning Farms (ILF) has successfully produced its Conservation Webinar Series since 2011, offering opportunities for online audiences to learn about the latest research and implementation efforts of conservation-related practices. To aid other organizations in producing webinars, ILF has created this toolkit which includes information on planning, promoting, designing, hosting, archiving, and evaluating a webinar, based on experience gained from producing and archiving hundreds of webinars.
