An improved particulate metering system is provided with variable blend, application rate, and section control. The system includes a plurality of particulate mixing areas, each having an air input and a plurality of particulate inputs. A plurality of particulate sources is provided, each being in communication with a particulate input of a particulate mixing area. A separate type of particulate can be in each of the plurality of particulate sources. The system includes a plurality of operated conveyances, each being in communication with a particulate source and a particulate input. Each of the plurality of particulate mixing areas can receive air from the air input and a separate type of particulate, and can discharge an air-particulate mixture. One or more metering controls operably control one or more of the operated conveyances.

The pressure of a fluid passing through several air entrainers can be controlled so as to more effectively move particulate material from one or more bulk hoppers to an end location. This is accomplished through use of an integrated, electric fluid pressure source, such as a fan in one or more of the segments. The pressure can be increased based upon a speed of an agricultural implement or a weight of the particulate material and/or the pneumatic flow can compensate for distance the seed must travel before planting. The entrainer can thus be installed with a high speed planting implement, thereby reducing downtime and facilitating repair.

An apparatus and methods for delivering a particulate product onto a soil surface proximate adjacently spaced crop rows. The apparatus includes a plurality of drop members supported by and spaced laterally along a boom structure such that each drop member is positioned between two adjacently spaced crop rows. The drop member extends downwardly from the boom structure toward the soil surface. The drop member supports a hopper which receives a quantity of particulate product. Diverging particulate product passageways supported from a lower portion of the drop member deliver the particulate product from the hoppers onto the soil surface adjacent the two adjacently spaced crop rows. In alternative embodiments, the drop members may also support liquid passageways for delivering liquid product to the soil surface with the particulate product and the drop members may support spray assemblies for spraying plants in the adjacent crop rows.

A method of inhibiting dry material clogs in a work vehicle having an air boom assembly includes moving the work vehicle at a vehicle speed along a ground surface, moving dry material from a holding tank onto a conveyor, and operating the conveyor at a conveyor speed, the conveyor speed being at least partially dependent upon the vehicle speed, moving material from the conveyor into a boom assembly with a blower, dispensing the dry material onto the ground surface through a plurality of nozzles of the boom assembly, and comparing the conveyor speed to a maximum acceptable conveyor speed. If the conveyor speed is greater than the maximum acceptable conveyor speed, the method includes performing at least one of the following: alerting the operator that the conveyor speed is greater than the maximum acceptable speed, and reducing the vehicle speed to thereby reduce the speed of the conveyor.

A seeding device system is presented for use with helicopters and other vehicles. The system includes a bulk seed container, a feed tube that connects the seed container to a metering device that precisely meters out seed, a flow control system that controls operation of the metering device, and a blower connected to a venturi that blows the seed outward from the helicopter. When seed is metered out of the metering device, the seed is sucked into the venturi and blown outward. The seed container is held in the back seat or cargo area of the helicopter and the blower, venturi and metering device are positioned exterior to the helicopter. This arrangement does not adversely affect the operational characteristics or aerodynamic properties of the helicopter. In addition, all components of the system are rigidly connected to the helicopter thereby increasing safety and control of the helicopter.

A method for adjusting operating parameters of an agricultural implement during a product-dispensing operation may include monitoring a location of the agricultural implement while performing a product-dispensing pass across a field. The method may further include determining that the agricultural implement will encounter an operating parameter boundary prescribing a change in an operating parameter of the agricultural implement. Moreover, the method may include determining a transition boundary along the product-dispensing pass based at least in part on a propagation delay for the prescribed change, where the agricultural implement will cross the transition boundary before the operating parameter boundary. Additionally, the method may include initiating the change in the operating parameter when the agricultural implement reaches the transition boundary such that the prescribed change in the operating parameter is complete when the agricultural implement reaches the operating parameter boundary.
