Abstract

Active ingredient-carrying hydrogels include at least a hydrogel and an active ingredient. The active ingredient is released from the hydrogel onto an agricultural substrate or at an agricultural site in a controlled manner. The hydrogel may include lactose, which may be provided by a milk permeate waste stream from the dairy or food processing industry.
