A stormwater channel includes a central channel bed flanked by left and right walls, with riparian planters and riparian reservoirs extending longitudinally through the channel. Water flows through the planters and reservoirs. Each planter contains plant-anchoring material and biochar. Riparian plant seeds or seedlings are planted in the planters and watered to form a riparian ecosystem. The stormwater channel also includes a fish migration channel adjacent to the riparian planters and reservoirs, enabling anadromous fish to swim upstream through the channel. Fish can be detected, trapped, and relocated past barriers using a drone.

A medium for water culture has a porous substance and photocatalyst particles formed of titanium-based compound particles that are supported on the porous substance, have absorption at a wavelength of 500 nm in a visible absorption spectrum, and have an absorption peak at 2,700 cm1 to 3,000 cm1 in an infrared absorption spectrum, in which a metal compound having a metal atom and a hydrocarbon group is bonded to the surface of each of the titanium-based compound particles through an oxygen atom.

A horticultural growth medium includes a filler and a binder. The binder is a moisture-cured, isocyanate-terminated quasi-prepolymer made from an organic polyisocyanate that includes a large proportion of 4,4-diphenylmethane diisocyanate. This binder system provides excellent curing properties and imparts excellent physical properties to the growth medium.
