Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The agricultural treatment system determines a vehicle pose of a vehicle as the vehicle moves along a path. The system identifies a first target agricultural object for treatment. Based on the determined vehicle pose, the system positions a treatment head of a first treatment unit such that a first projectile fluid may be emitted by the first treatment unit at the identified first target agricultural object. The system then causes an emitter to emit a fluid from the treatment head at the first target agricultural object.

A system for applying an herbicide to an agricultural field includes a sensor configured to measure total vegetation density in the agricultural field; and an applicator vehicle comprising a chassis, a liquid holding tank carried by the chassis, and at least one nozzle carried by the chassis and in fluid communication with the liquid holding tank. A controller is configured to control an amount of flow of herbicide through the nozzle(s) based on the total vegetation density measured by the sensor. A method of applying an herbicide to an agricultural field includes measuring a total vegetation density in the agricultural field and spraying a variable amount of an herbicide through at least one nozzle onto the agricultural field. The amount of herbicide is based on the measured total vegetation density, without regard to distinction between crop and weed.

An agricultural implement and a metering apparatus for the agricultural implement to deliver a material to a material depositing apparatus. The metering apparatus includes metering roller, an integrated motor operatively connected to the metering roller, and a motor drive operatively connected to the integrated motor. A controller is operatively connected to the integrated motor and to the motor drive wherein the controller transmits a drive signal to drive the integrated motor and receives a status signal from the integrated motor. The drive signals drives the motor, which includes the roller coupled to a motor spindle, at a variable rate of speed to reduce pulsing. In one embodiment, the agricultural implement is an air cart.

A system for dispersing a chemical in a surface water body includes an aerator device, having an injector positioned at a bottom of the surface water body; and a holding tank to store the chemical adjacent to the surface water body; and a metering pump connected to the holding tank, the metering pump having a computing device to program the metering pump; the metering pump is programed to inject an amount of the chemical to the injector at a rate; and the injector disperses the chemical throughout the surface water body.

A change of state of weed seeds to having reduced germination viability in one minute by illuminating a seed in a processing theater to achieve at least one of 0.66 J/cm2 cumulative illumination energy, and 0.06 W/cm2 irradiance, of at least one of an Indigo Region Illumination Distribution (IRID), and Medium Wavelength Infrared (MWIR) radiation, preferably 2-8 microns, with no high energy transfers, scalding, heat shock, cooking or incineration. The MWIR radiation from heated borosilicate glass or glass powder at just under 500 C offered a peak MWIR emission of 3.75 microns, and was unexpectedly effective, and can be used in a radiant and transmissive weed seed accumulator transport belt. The process can be incorporated into a harvester combine to convert a tailings flow prior to discharge on an agricultural field. An illuminated harvest combine using an illuminator according to the invention allows reduction of the weed seed bank.

A method for plant treatment, including: receiving a first measurement for a plant from a sensor as the sensor moves within a geographic area comprising a plurality of plants; in response to receipt of the first measurement and prior to receipt of a second measurement for a second plant of the plurality, determining a set of treatment mechanism operation parameters for the plant to optimize a geographic area output parameter based on the first measurement and historical measurements for the geographic area; determining an initial treatment parameter for the plant; and operating a treatment mechanism in a treatment mode based on the set of operating parameters in response to satisfaction of the initial treatment parameter.
