Nitrogen Planning and Management in Organic Production of Annual Crops

organic N workshop (big)

In this 3-part series, participants will learn how to estimate nitrogen release from diverse organic sources and translate that knowledge to nitrogen fertilization plans and regulatory reporting requirements. Over the 3 sessions, we will cover the most common sources of nitrogen and complete a full nitrogen budget. Sessions will have group instruction followed by small-group breakouts to allow participants the opportunity to utilize information from their own farm in the nitrogen budget worksheet.
