In a fluid injection system for dispensing a solution, said fluid injection system comprises a feeder tank having a product to be dispensed therein, an inlet connection for diverting fluid from a flow line to a fluid nozzle means and an outlet connection for dispensing the solution into the flow line or onto a matter. The fluid nozzle means is in communication with the feeder tank and the inlet connection and the fluid injection system controls a flow rate of fluid at which the fluid nozzle means introduce the fluid into the feeder tank based upon characteristics comprising solubility of the product at a temperature of the fluid in the feeder tank, weight of the product to be dispensed or to be dissolved in the feeder tank, and dispensing time, and the fluid injection system controls a flow rate of the fluid nozzle means to satisfy equation: F=(W)/(T×S) wherein, F is the flow rate of the fluid nozzle means, W is weight of the product in the feeder tank, T is dispensing time and S is solubility of the product at the temperature of the fluid in the feeder tank.

A system for agricultural irrigation water oxygenation for enriching soil oxygen level comprises a source of compressed oxygen (and not compressed air) coupled to a water line feeding an irrigation system, such as a drip irrigation system. The coupling system may include a pressure sensor for measuring the pressure in the water line, a solenoid safety valve, a control valve, a flow meter and a controller that controls the flow of oxygen from the source of compressed liquid oxygen to the water line using the components of the coupling system, without using a special cavitation valve and using off-the-shelf components while achieving the same benefits as a system incorporating the special cavitation valve.

The present invention relates to a water extraction system for up-concentration of organic solutes comprising a flow cell comprising a membrane; said membrane comprising an active layer comprising immobilized aquaporin water channels and a support layer, and said membrane having a feed side and a non-feed side; and an aqueous source solution in fluid communication with the feed side of the membrane. The system also includes an aqueous source solution in fluid communication with the feed side of the membrane and an aqueous draw solution in fluid communication with the draw side of the membrane. The aqueous source solution comprises the organic solutes. The membrane module comprises an inlet and an outlet for the aqueous draw solution. The aquaporin vesicles are formed by self-assembly of block copolymers in the presence of an aquaporin protein suspension.

A method for irrigation of a crop capable of producing Cannabidiol (CBD) comprises irrigating the crop with a nanobubble hydrogen rich water (HRW-nano), whereby a concentration of CBD in the crop increased as a result of irrigating with the HRW-nano, compared to irrigation with an irrigation water having the same composition except without added hydrogen (control irrigation).

A system comprising a boom, a plurality of nozzles disposed along the boom, a light disposed on the boom to illuminate a spray pattern from at least one nozzle, a camera disposed on the boom to capture a first image of a spray from the at least one nozzle at a first time and a second image of no spray from the at least one nozzle at a second time, and a processor to calculate a difference between the first time and second time to determine a pulse width modulation of the at least one nozzle.

A system having: a boom; at least one nozzle assembly attached to the boom; and a nozzle or a second nozzle assembly; wherein the at least one nozzle assembly and the second nozzle assembly each comprise a nozzle and at least one light; wherein the at least one light is disposed to illuminate a spray from an adjacent nozzle assembly or nozzle.

The apparatus for providing nutrients to plants in a hydroponic plant growing system contains a nutrient release capsule and a capsule holder. The nutrient release capsule is a sustained release nutrient product comprising a hydroponic plant fertilizer center with a biopolymer outer coating to slow the release of the nutrients into the liquid (e.g., water). The capsule holder consists of a modifiable structure that can exist in multiple configurations to deliver different release dosage behaviors into and in response to the liquid for the hydroponic plant fertilizer.

The present invention provides a measurement apparatus 1 including: a detection unit 2 configured to detect a pressure according to a shape change of a tubular structure whose shape changes according to a supplied amount of a liquid that flows therein; a time specification unit 3 configured to specify, based on the pressure detected by the detection unit 2, a supply time during which the liquid was supplied; and a supplied amount calculation unit 4 configured to calculate a supplied amount of the liquid based on the supply time.

A system and method for providing fertilizer for crop production in an aqueous solution comprising nano-sized fertilizer particles, which are free of any chemical side chain and free any micelle to protect the nano-sized particle from re-agglomeration, suspended therein for improved uptake by the population of the crop.

A plant cultivation device and a greening apparatus thereof are provided. The plant cultivation device includes a fixing member which includes a first channel, a shared channel and a plurality of first through-holes. The first through-hole is connected with the first channel and the shared channel, and passes through an upper surface of the fixing member. Both the first through-hole and the shared channel are stack-up with each other, and the first through-hole is located above the shared channel. The shared channel is configured to fill with a cultivation medium,and the first channel is configured to store water flowing from the shared channel by the first through-hole when too much water is stored in the shared channel. The present disclosure can optimize a growing environment of plants.
