Abstract: An electric measurement method and apparatus for detecting a mass by an electric capacity (permittivity) or a material's dielectric constant, or alternatively, electric inductance (permeability). The mass may be any phase or combination of phases. The mass may be stationary or flowing. It may comprise discrete particles such as grain, or manufactured products such as ball bearings or threaded fasteners, etc. The mass may be a flow element in a rotameter or similar flow measurement device. The sensor comprises a volume which may be completely full or only partially full of the material. The material may be discrete components or a continuum. Sensor signals may be received by existing planter monitoring systems. In some embodiments the flow sensors are positioned external to the application port. In some embodiments sensors may be utilized which are responsive to the refractive index variation of specific chemicals.

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 method and apparatus for minimizing the volume of a liquid carrier used for delivering an agricultural product into a furrow during planting. The apparatus includes a seed tube assembly for dispensing seed. A seed firmer assembly is operatively connected to the seed tube assembly. A seed firmer application tube assembly is mounted to the seed firmer assembly. The seed firmer application tube assembly has an outlet end for dispensing a carrier containing an agricultural product. A seed firmer brush is mounted to the outlet end of the seed firmer application tube assembly. The seed firmer brush is configured to contact the carrier containing the agricultural product during the dispensing thereof and brushing the carrier containing the agricultural product onto the seed being dispensed from the seed tube assembly.

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.

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 dispensing multiple low rate agricultural products, includes a syringe-based agricultural product metering system, a number of agricultural product tubes, and an agricultural product metering system. The agricultural product metering system is operably connected to sources of low rate agricultural products. The agricultural product tubes are 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.
