  • Patent number: 11230505
    Abstract: Disclosed herein are microbial consortia and compositions including microbes, for example, for use in agricultural or biodegradation applications. In some embodiments, soil, plants, and/or plant parts (such as seeds, seedlings, shoots, roots, leaves, fruit, stems, or branches) are contacted with a disclosed microbial consortia or composition including microbes. The microbial consortia or microbe-containing compositions may be applied to soil, plant, and/or plant parts alone or in combination with additional components (such as chitin, chitosan, glucosamine, amino acids, and/or liquid fertilizer). In additional embodiments, the disclosed microbial consortia or compositions including microbes are used in methods of degrading biological materials, such as chitin-containing biological materials.

  • Patent number: 11231305
    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.

  • Patent number: 11026362
    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.

  • Patent number: 10948323
    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.
