Abstract: A jet agitation system for preparation of agricultural seeding and other fluids ensures breakdown of mulch clumps and complete mixing of the seed-mulch-water mixture. The jet agitation system includes a tank with an access port at the top, a non-clogging pump coupled to withdraw the mixture from the bottom of the tank, a spray head and control valves terminating supply and return hoses and a manifold for distributing fluid to a plurality of nozzles or jets disposed within the tank. The jets are preferably positioned above the fluid level and expel liquid under pressure which breaks down the paper mulch and circulates the fluid in the tank, thereby fully mixing it. Fluid may be supplied to the nozzles or jets during spraying in order to maintain the mixture in a fully mixed state.

Abstract: An apparatus for spraying mixtures of solid and liquid materials includes a tank; a pump; an inlet line from the tank to the pump; a return line from the pump to the tank; a spraying nozzle; a nozzle supply line from the pump to the nozzle; a nozzle to the tank; and first and second valves for regulating the respective amounts of mixtures to be fed either to the nozzle, the nozzle supply line, the nozzle return line or the return line from the pump to the tank. By providing two separate valves and return lines, one at the pump and one at the nozzle, constant agitation of the tank contents is maintained and clogging anywhere in the system, particularly in the nozzle hose, is avoided.
