A mobile system for growing microorganisms and circulating nutrients for administering to plants. The system has minimal interior obstructions that can be easily removed for effective cleaning. The system comprises a mobile structure; a vessel supported by the structure for receiving water and nutrients; a pump supported by the structure; a generator supported by the structure for powering the pump; a vessel outlet from a bottom portion of the vessel to the pump; a first discharge line from the pump extending from the pump into the bottom portion of the vessel, wherein the contents of the vessel can be circulated by the pump from the vessel outlet back into the vessel through the first discharge line; a second discharge line from the pump for discharging contents of the vessel; and an aerator for injecting air into the first discharge line for aerating the contents of the vessel.

Apparatus, system, and method are provided herein for causing and controlling the injection of fertilizer into an irrigation of an irrigation system. The fertigation system comprises a fertigation supply unit including at least one storage container containing at least one of a fertilizer component, a herbicide, and an insecticide coupled to a irrigation of the irrigation system. A fertigation control unit is coupled to the fertigation supply unit. The fertigation control unit is configured to cause the fertigation supply unit to inject at least some of the fertilizer component, herbicide, and/or insecticide into the irrigation. The fertigation control unit can cause the fertigation supply unit to inject the fertilizer component, herbicide, and/or insecticide in response to at least air temperature data and/or soil temperature data received from a sensor unit, or in response to user input at the fertigation control unit.

An apparatus for use in establishing or re-establishing plant growth over a land area. The apparatus includes a supply of a growing medium and an arrangement including at least one delivery outlet for delivering the growing medium at spaced intervals from a height onto a soil surface of the land area. The growing medium contains seeds or is delivered in tandem with and on top of seeds deposited on the soil surface or deposited onto or adjacent to seeds or seedlings already deposited on the soil surface.

A cross-linked, water absorbent polymer is mixed with desirable additives and coated to prevent water absorption to create a blend that is added to water injection systems for turf and soil maintenance. The coating is rinsed off the water absorbent polymer resulting in expansion of the polymer into a gel-like substance. The water absorbent polymer has the ability to retain water and nutrients in the soil preventing nutrient runoff and reducing watering frequency. Injection of the water absorbent polymer directly into soil reduces waste and reduces hazard caused by slippery material left on soil surfaces. The method and system for mixing and injection into soil is disclosed.

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 fertilization system may include a flow diverter to divert a portion of water from a ground irrigation system through a tank containing fertilizer and back into the ground irrigation system by creating a high pressure region up stream of the flow diverter and a low pressure region down stream of the flow diverter to provide hydraulic operation of the fertilization system.

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 system for irrigating an agricultural field includes a high-clearance vehicle (e.g., a sprayer vehicle) and a hose configured to connect an external water source to the high-clearance vehicle while the high-clearance vehicle traverses the agricultural field. A method for irrigating an agricultural field includes connecting an external water source to a high-clearance vehicle by a hose, and dispensing water from the nozzles of the high-clearance vehicle while the external water source remains connected thereto and while the high-clearance vehicle traverses the agricultural field.

A plant irrigation dispenser and method controllably dispenses nutritional compositions to a plant. The dispenser comprises a housing defined by a first end and a second end that forms a channel. Impaling members form at the second end of the housing. The housing encloses multiple chambers that contain the nutritional composition. The chambers have a filling end and a dispensing end that forms an opening. A membrane seals the opening. Rotatably manipulating and axially displacing the chambers in relation to the housing allows the impaling members to tear the membrane, so that the nutritional compositions flows through the openings, and onto the plant. A press is in communication with the chamber cavities, so that axially displacing the press in a downward direction forces the nutritional compositions through the openings. A valve assembly retains and manipulates plugs in alignment with the openings to selectively couple and decouple the respective openings.

Crop input application systems, methods and apparatus are provided. In some embodiments, an irrigation system is provided with a reel in fluid communication with a liquid source. In some embodiments, a drop assembly is incorporated in an irrigation system. In some embodiments, a crop applicator system includes a reel positioned between adjacent rows of crop.
