Claim 0:
1. A method of delivering an active ingredient to an agricultural substrate, the method comprising:
combining, in a spray tank, an active ingredient with a hydrogel precursor to produce a carrier hydrogel precursor mixture;
delivering the carrier hydrogel precursor mixture from the spray tank to the agricultural substrate at an agricultural site, wherein prior to delivery, the carrier hydrogel precursor mixture is not cross-linked; and
at the agricultural site, allowing ambient light induced cross-linking, in the absence of a photoinitiator, of the carrier hydrogel precursor mixture to produce a carrier hydrogel,
wherein the carrier hydrogel is adapted to control release of the active ingredient to the agricultural substrate, control uptake of the active ingredient by the agricultural substrate, or both control release and control uptake of the active ingredient.
