An autonomous vehicle platform system and method configured to perform various in-season management tasks, including selectively applying fertilizer, mapping growth zones and seeding cover crop within an agricultural field, while self-navigating between rows of planted crops and beneath the canopy of the planted crops on the uneven terrain of an agricultural field, allowing for an ideal in-season application of fertilizer to occur once the planted crop is well established and growing rapidly, in an effort to limit the loss of fertilizer.

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.

Devices, systems and methods for mixing and/or introducing agrochemicals, comprising a mixer including a mixing chamber in which a liquid is able to flow, and a delivery point located on the mixing chamber for delivering an agrochemical into the mixing chamber, wherein the mixer includes means for generating backpressure in the liquid and the agrochemical in the mixing chamber, and a mixer system including a mixer, an injector, and an agrochemical source, wherein the injector is adapted to receive an agrochemical from the agrochemical source, and a method including the steps of supplying a liquid into a mixing chamber of a mixer or mixer system, delivering an agrochemical into the mixing chamber, and generating backpressure to the liquid flowing through the mixing chamber to effect mixing of the liquid and the delivered agrochemical.

Methods and systems for providing nutrients to a plant are provided herein in which a feed solution containing water and solubilized nutrients are delivered to the plant at a desired ratio of concentration of water to fertilizer at each watering event in order to provide the plant with a consistent water to mineral ratio within their vascular system.

A fertilizer application system for a liquid fertilizer concentrate includes a container containing a first fluid. A siphon is disposed on the container and includes two inlets and an outlet. A flow control valve is configured to selectively control an amount of first fluid flowing through the siphon based on ambient temperature of an environment outside the container. A siphon tube includes a siphon tube first portion in fluid communication with the first fluid, and a siphon tube second portion fluidly coupled to an inlet of the siphon. The first fluid includes a liquid fertilizer concentrate comprising a nitrogen containing source, a phosphorous containing source, a sulfur containing source, a potassium containing source, an iron containing source, and water.

Systems, methods, apparatus and computer program code are provided deliver fertilizer to targeted areas. In some embodiments, a system includes a memory configured to store data associated with an area to be fertilized, the data including information identifying a crop and soil analysis data associated with the area and a processor configured to receive sensor data associated with the area, the sensor data including information identifying a current weather condition and a current soil condition, automatically generate a proposed recipe of a fertilizer mixture, the recipe including information identifying a combination of elements and a dosage of each element, determining whether the proposed recipe satisfies at least a first rule; and operating a delivery system to deliver the fertilizer mixture to the area.

The present disclosure generally provides a fertigation process comprising providing a nitrification inhibitor composition; providing a urea ammonium nitrate fertilizer composition; combining the nitrification inhibitor composition with the fertilizer composition; and applying the combined composition during a growing cycle of a crop using an overhead irrigation system. The present disclosure also relates to this fertigation process wherein the nitrification inhibitor comprises dicyandiamide and dimethyl sulfoxide and the crop is corn.

In various embodiments, an apparatus for growing plants is provided. The apparatus may include an irrigation apparatus, an accommodating space for accommodating one or more seed mats, and a controller which is configured to control the irrigation apparatus by a program controller. The irrigation apparatus includes a water circuit system for feeding water to the seed mats. The water circuit system includes at least one inlet, a water tank, at least one water circuit pump and at least one outlet. The irrigation apparatus includes a sensor which is configured to determine a conductance of the fed water.

A method for monitoring and controlling chemical concentration in a direct injection agricultural sprayer system monitors initial chemical concentration output from a chemical tank, carrier flow from a carrier tank, and mixed chemical concentration at nozzles of the spray system downstream of individual mixing points of the nozzles. Flow from the carrier tank and/or the chemical tank are controlled to target a set concentration at each of the nozzles. The initial chemical concentration establishes maximum concentration and a calibration curve for a chemical being applied and the mixed chemical concentration establishes an applied concentration in view of the calibration curve. A system is provided for the method.
