AMES, Iowa — Edge-of-field practices play a key part in conservation and nutrient management. In an effort to help farmers choose the best practices for their land, Iowa Learning Farms will host a webinar on Wednesday, Oct. 7 at noon about using decision trees.

Edge-of-field practices, such as bioreactors, saturated buffers and wetlands, can effectively address water quality concerns, but it is important to select the right practice for your site and goals.

Chris Hay.Chris Hay, senior manager-production systems innovation with the Iowa Soybean Association, will cover the basics of edge-of-field practices and some of the siting considerations. Hay will also discuss decision trees that can help farmers, landowners and conservation professionals select an edge-of-field practice.

The decision trees were developed as part of the Whole Farm Conservation Best Practices Manual. The full manual is available as a free download from the Iowa State University Extension Store or the Iowa Learning Farms website. “Edge-of-field practices are some of the best performing water quality practices, but it can be confusing to know what practices will work at a particular site,” said Hay. “These newly developed decision trees can help both farmers and conservation professionals select edge-of-field practices that best match their situation.”
