Claim 11:
12. A method of releasing an active ingredient from a carrier hydrogel, the method comprising:
combining in a spray tank an active ingredient, a hydrogel precursor, and water to produce a dilute carrier hydrogel precursor mixture, wherein the dilute carrier hydrogel precursor mixture is free of a photoinitiator; and
delivering the dilute carrier hydrogel precursor mixture to an agricultural site, wherein prior to delivery, the carrier hydrogel precursor mixture is not cross-linked, and
wherein at the agricultural site, the dilute carrier hydrogel precursor mixture is exposed to ambient light to produce a crosslinked carrier hydrogel, whereby the active ingredient is released from the crosslinked carrier hydrogel at the agricultural site.
