Abstract: A system for dispensing crop input products from multiple meters per crop row, including: a) a georeferencing module configured to receive and process georeferenced location information; b) a prescriptive control module configured to receive the processed georeferenced location information from the georeferencing module and utilize the georeferenced location information to generate specific prescriptive rate information for individual meters in the field; and, c) a meter controller module operatively connected to the prescriptive control module. The meter controller module is configured to utilize the specific prescriptive rate information to individually control multiple meters per crop row, to simultaneously dispense crop input products at specific prescriptive rates at georeferenced locations throughout the field.

Abstract: A flow sensor apparatus for monitoring a directed stream of an agricultural product from an application port of a supply tube. The directed stream has a target directed portion and an off-target portion. A sensor housing includes a conical flow receiving element and a sensor body. The receiving element has an inlet orifice at a first end and a receiving element outlet at a second end. The first end is smaller than the second end. The sensor body has a sensor inlet end positioned to receive a target directed portion of the directed stream from the receiving element outlet of the conical flow receiving element wherein an off-target portion of the directed stream is not sensed. The sensor housing and sensor element are positioned external to the application port and thus positioned to provide measurement, targeting, and timing of the agricultural product.

Abstract: A system for electronically pulsing agricultural product with seed includes a seed transport mechanism affixed to a seed planter row unit. A seed sensing device senses dispensation of the seed from the seed transport mechanism. An agricultural product conduit dispenses agricultural products into the seed transport mechanism to provide dispensing of the products with the seed as the seed and product exit the seed transport mechanism. A control interface electronic system dispenses a particular quantity of product with the seed in the seed transport mechanism. A pulsing valve dispenses products from the conduit when the seed sensing device senses the dispensation of the seed. A seed release speed is provided which is proportional to the ground speed of the seed planter row unit to minimize seed tumbling and optimize accurate placement of seed and product at varying ground speeds of the row unit.

Abstract: A system for dispensing low rate agricultural products, includes a syringe-based agricultural product metering system, at least one agricultural product tube, and an agricultural product metering system. The agricultural product metering system is operably connected to a source of low rate agricultural products. The agricultural product tube is operatively connected to the agricultural product metering system. The agricultural product metering system is configured to dispense liquid low rate agricultural products at a low rate defined as below 3.7 fluid ounces per 1000 row feet.

Abstract: A supply tube assembly for measuring a liquid agricultural product application rate. An upstream portion of a supply tube has an upstream portion outlet end. A downstream portion has a downstream portion inlet end. The sensor body assembly includes a sensor body, a first sensing plate, and a second sensing plate. The sensor body has a sensor inlet end positioned to receive an inlet flow of the liquid agricultural product from the upstream portion and a sensor outlet end positioned to receive an outlet flow of the liquid agricultural product. The sensor body is an enclosure having a cross sectional area larger than the cross sectional area of the upstream portion of the supply tube and the downstream portion of the supply tube. Electronic components are configured to measure the liquid agricultural product application rate between the first sensing plate and the second sensing plate.

Abstract: A system for dispensing liquid agricultural products with seed includes a control system; a seed transport mechanism; an agricultural product supply system; and, a seed brush assembly. The seed transport mechanism is affixed to a seed planter row unit. The agricultural product supply system is configured to dispense agricultural products in response to an output signal from the control system. A brush housing structure of the seed brush assembly receives seed from the seed transport mechanism. A brush of the seed brush assembly has bristles positioned within the brush housing structure. The agricultural product supply system is configured to dispense the liquid agricultural products onto the bristles. The bristles are configured to minimize the resistance associated with the passage of seed past the wetted bristles. The liquid agricultural product is transferred from the brushes onto the seed as the seed is dispensed prior to the seed hitting the ground.
