Vegetable crop production is the third leading agricultural industry in Wisconsin behind dairy and grain production. The primary region for intensively managed vegetable cropping is located in central Wisconsin, with large production regions located near Spring Green, Janesville, Fond du Lac, Markesan, Manitowoc, and Cumberland also playing a vital role in the industry. The current vegetable cropping system inherently demands high fertilizer inputs, specifically nitrogen. Due to current global instability in oil producing regions, chemical nitrogen prices have risen drastically and the potential remains for future price volatility. Exploring alternative cropping systems as a means for providing nitrogen as well as improving the sustainability of the cropping systems without limiting yield or quality of harvested crops is a rapidly developing area of needed research.
