A row unit of an agricultural planter includes a seed meter. The seed meter includes a seed disk within a seed meter housing. The seed disk is positioned in the seed meter housing such that the disk rotates and includes a seed release point. A drive member is operatively connected to the seed disk such that the drive member selectively rotates the disk. The seed disk is angularly positioned and is a conical-shaped member with a central axis and includes seed cells radially positioned about an outer portion. The seed disk is substantially non-perpendicular to the central axis. An air pressure source also is included to adhere seed to the disk.

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.

A delay period timing system for a seeding implement with a feed control. A distribution network conveys products to the furrow openers, and a feeding mechanism controls flow of products into the distribution network. A flow sensor downstream from the feeding mechanism detects when products are flowing at a sensing location, and a timer measures a delay period between the time the feeding mechanism starts or stops flow and when the flow sensor starts or stops detecting flow. The delay period is adjusted to account for the location of the flow sensor. A method of determining the delay period includes determining the length of the distribution network and determining the speed of flow of the products. The system can be used on seeding implement with or without sectional control.

A spreader with a material divider that is adjustable by movement of a plurality of internally movable parts therein to change a stream of material which flows in an arbitrary manner to the centrifugal disk(s) to achieve a desired symmetrical or asymmetrical spread pattern.

Agricultural seed planting systems include a processing unit, a frame, a furrow opener coupled to the frame for opening a furrow in soil, and a sensor in communication with the processing unit and adapted to sense a characteristic associated with seed planting. The sensor may generate a signal associated with the sensed characteristic and the processing unit may receive the signal. In some aspects, the sensed characteristic may be either a soil characteristic or a seed characteristic. Information associated with the sensed characteristic can be saved in memory for future use and to assist with more effective planting in the future.

Various planting machines and planting methods are described. A planting method may include filling a seed pool with first-type seed, metering the first-type seed from the seed pool with a metering member, and then evacuating the first-type seed from the seed pool. The method may further include filling the seed pool with second-type seed, metering the second-type seed with the metering member, evacuating the second-type seed from the seed pool, and then refilling the seed pool with the first-type seed. First-type and second-type seed may be evacuated to separate temporary storage chambers, and the seed pool may be filled from the temporary storage chambers, as well as from bulk storage containers. A seed valve of a planting machine may include temporary seed storage chambers for different seed types. The seed valve may fill and evacuate a seed pool through rotation of various valve members and selective application of a vacuum.

An activated-release, water-insoluble or slowly-soluble coating is utilized on fertilizers, pesticides, seeds, medicine, and other granules to precisely time the release of the active ingredient of the granules, for purposes such as fertilizer and pesticide release as well as to initiate seed germination. An external stimulus, or activating agent, including, but not limited to, microwaves, ultrasonic waves, X-rays, radio waves, electromagnetic waves, radar waves, sonar waves, magnetic induction, (or pulses of any of the foregoing), specific chemical, bacteria, or fungus organism (such as ionic or non ionic surfactants, organic solvents, specifically cultured bacteria, fungi or catalytic agents) is used to break the coating, thus allowing for the release or germination. An activating device may be mounted on or in a tool bar, cart, or other apparatus pulled by a tractor, all-terrain vehicle (ATV), airplane, helicopter, or other implement and passed over a field, sprayed onto or injected into the soil, when the granule content is actually needed or germination is sought. The present disclosure also relates to liquid fertilizers of complex chemistry that are not readily available to plants; activation will degrade the nutrient compounds to readily-available forms.

A farming machine identifies and treats a plant as the farming machine travels through a field. The farming machine includes a pair of image sensors for capturing images of a plant. The image sensors are different, and their output images are used to generate a depth map to improve the plant identification process. A control system identifies a plant using the depth map. The control system captures images, identifies a plant, and actuates a treatment mechanism in real time.

A method and system for producing a plant-based image includes receiving a source image; screening the source image into a set of picture elements; and producing raster data indicating at least a type or density of seeds or plants to plant for each picture element.

A method and apparatus for automatically opening a seed packet and dispensing the contents of the same for planting is disclosed.
