An erosion control slurry is disclosed. The slurry includes water and a substrate, wherein the substrate comprises: mulch at a weight of x; bentonite clay at a weight of about 0.25x to about 0.495x; and cellulosic water dispersible polymer or starch at a weight of about 0.0025x to about 0.125x. Also disclosed are a substrate that can be mixed with liquid to provide an erosion control slurry, and methods of controlling or reducing erosion.

A semi-closed loop hydraulic circuit includes a prime move, a first hydraulic circuit operatively coupled to the prime mover, and a second hydraulic circuit operatively coupled to the prime mover. The second hydraulic circuit is fluidly coupled to the first hydraulic circuit.

A substrate and a slurry for erosion control and/or hydroseeding are disclosed. The substrate includes mulch and a cover composition including bentonite clay and cellulosic water dispersible polymer or starch. Other desired optional ingredients may also be included. Methods of controlling or reducing erosion control are also disclosed.

The invention is an apparatus unit that adjusts the dispersion from a compartment to an aqueous solution in response to an independent variable such as an environmental factor, in order to optimize seeding, marking, warning or treatment. The compartment enables any selection of solids, liquids or gasses to be contained and mixed when ready for dispersion. A preferred embodiment is a solar powered pump, self-contained within a buoy over a shallow tidal pool, for the purpose of distributing seeds for marine vegetation under ideal conditions for propagation. The unit provides for sensing and measurement of the environment, then adapting the dispersion for optimum effect.

An erosion control substrate and slurry are disclosed. The substrate includes mulch, a cover composition including bentonite clay and cellulosic water dispersible polymer and/or starch, and optionally surface-treated HPMC. Other desired optional ingredients may also be included. Methods of forming a slurry and methods of using the slurry for erosion control are also disclosed.

Methods and apparatus for adjusting a delivery, distribution, emission, or spray of an adaptable material are disclosed. The adaptable material is contacted by a compatibly-selected kinetic energy fluid. The contact provides a motive force to move the adaptable material to or from an outlet of a spray fixture. The spray fixture is adjustable to emit various forms of drops, mists, extrusions, emulsions, or fibers. The adjusting is based on characteristics of a feedstock material, the adaptable material, the compatibly-selected kinetic energy fluid, or combinations thereof.

A self-contained hydroseeding packet that can be quickly loaded into a portable hydroseeder having seed, mulch and fertilizer in a predetermined ratio bound by a tacifier. The seed, mulch and fertilizer dissolve into a slurry when combined with water. Optionally, the packet can have a color to identify areas previously seeded. The seed, fertilizer, and mulch are bound by a water soluble binding agent and is biodegradable.

Systems and methods for seed germination and planting include: a germinator unit providing an environment for seeds to germinate in water, and means to deliver the germinated seeds in batch form, suspended in an aqueous hydrogel; and a planting unit to accept batches of suspended seeds and dispense the seeds, preferably in singulated manner, to selected locations in a planting environment. The planting unit may be man-portable, mounted on a trailer or autonomous vehicle, or substantially stationary for use in a greenhouse. The planting environment may be a field or it may be a planting tray, pot, or other container for use in a greenhouse.
