Land cultivating systems and methods utilizing high-pressure fluid jet cutting techniques are disclosed. An example system includes a mobile unit, a traveler arrangement operably coupled to the mobile unit to ride on the surface of stubble residues as the mobile unit moves across land to be cultivated, and a fluid jet cutting head supported by the traveler arrangement. The cutting head is configured to selectively discharge a high-pressure fluid jet to make a cut through the stubble residues and underlying soil as the mobile unit moves across the land. A soil opening device is provided to form a furrow in the ground in line with the cut made by the high-pressure fluid jet, and a liquid injector nozzle is provided to discharge fertilizer or other chemical(s) into the soil.

A system for changing pressure in one or more tires of a self-propelled agricultural machine according to a load differential determined using load sensors on opposing locations of the machine. A load differential may be caused by a disproportionate distribution of forces and/or weight on the machine. Load sensors proximal to the tires may allow determining corresponding loads on the tires and, in turn, the load differential. As a result, tires experiencing greater loads may be inflated, whereas tires experiencing lesser loads may be deflated. In addition, a Human Machine Interface (HMI) may be provided in the operator cab to allow an operator to have further control over tire inflation on the fly while operating the machine.

A mobile turf sprayer operates to spray a product onto a turf site. In some embodiments the mobile turf sprayer identifies a plurality of regions of the turf site to be sprayed and automatically sprays product onto those regions as the mobile turf sprayer moves about the turf site.

In one aspect, a crop input applicator is provided. In one aspect, the applicator comprises a valve (e.g., voice coil valve) disposed to deposit liquid on or near a seed furrow and/or on or near a seed. In one aspect, the applicator includes one or more seed sensors disposed to detect passage of seeds.

The present invention provides an improved mechanism for centering implements in agricultural fields by providing a laser guidance system with a laser attached to the implement. The laser may operate to emit a beam in order to produce a spot or beam onto the field which an equipment operator may visually target to improve steering of the implement. The laser may be centered on the implement, and the beam produced by the laser may be directed forward within a steering range of the implement and within a field of view of the equipment operator.

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.

An autonomous spraying platform is provided. The autonomous spraying platform has a main frame platform supported by a first and a second wheel in tandem. Supported by the main frame platform and extended perpendicular thereto are extended booms having multiple movable and/or telescoping arms which touch the ground on each side by small wheels for balance and sensing of the ground. Liquids, foams or powders, which may carry pesticides, herbicides, insecticides, fungicides, fertilizers or other pro-growth ingredients, may be dispensed across the bottom edge of the extended booms. The main frame platform may be controlled locally by sensors utilizing GPS (or other positioning technology) or remotely by a computer or even alive operator. The device may allow for real-time precise delivery of pro-growth materials to plants.

A spreading device is disclosed for spreading vehicles for discharging spreading agents. The spreading device includes at least one tank for receiving liquid spreading agents to be spread and at least one rotationally-driven discharge device, connected via a provided supply unit to the tank. The discharge device has at least one base body and one cover securely connected to the base body, wherein the base body defines a receiving chamber (AR) for the supplied liquid spreading agent and is in the shape of a cylinder. The base body has at least one bottom section, forming an underside (U) of the discharge device, with an inlet opening and at least one wall section projecting from the bottom section and concentrically surrounding an axis of rotation (RA). The discharge device has multiple discharge units, each having a discharge opening, for dispensing the liquid spreading agent from the receiving chamber (AR).

A system includes a fluid supply line, a plurality of nozzle assemblies positioned and oriented to spray portions of a target, and a plurality of electrically actuated valve assemblies configured to control fluid flow to the nozzle assemblies. The system also includes a controller connected in communication with the plurality of electrically actuated valve assemblies and configured to individually actuate the valve assemblies between a closed position and an open position. The controller is configured to receive an orientation of each nozzle assembly relative to the target and determine a duty cycle of each valve assembly based on the orientation of the respective nozzle assembly. The controller is configured to actuate each valve assembly based on the respective orientation to provide a desired fluid characteristic of the fluid emitted from the respective nozzle assembly.

The current disclosure relates to a chemical-free composition that increases the nutritive value of crops, by increasing vitamin levels in the crop produce. The composition disclosed in the current invention also increases crop yield. The composition does not contain any chemicals and can increase vitamin levels in the crop produce by non-transgenic means, which can help to alleviate deficiency diseases due to malnutrition in an inexpensive and sustainable manner.
