abstract systems, methods and apparatus for selecting an agricultural input. first and second inputs are in communication with a seed meter. a selection apparatus constrains the seed meter to deposit only one of the input sources such that the seed meter is enabled to alternate between depositing the first and second inputs. processing circuitry controls the selection apparatus to alternate between the first and second inputs. abstract of patent summary: "agricultural input selection systems, methods and apparatus". These are systems, methods and apparatus for selecting an agricultural input. The first and second inputs are in communication with a seed meter. A selection apparatus restricts the seed meter to deposit only one of the input sources such that the seed meter is allowed to alternate between depositing the first and second inputs. The processing circuitry controls the selection apparatus to switch between the first and second inputs.abstract systems, methods and apparatus for selecting an agricultural input. first and second inputs are in communication with a seed meter. a selection apparatus constrains the seed meter to deposit only one of the input sources such that the seed meter is enabled to alternate between depositing the first and second inputs. processing circuitry controls the selection apparatus to alternate between the first and second inputs. tradução do resumo resumo patente de invenção: "sistemas, métodos e aparelho de seleção de entrada agrícola". trata-se de sistemas, métodos e aparelho para selecionar uma entrada agrícola. a primeira e a segunda entradas estão em comunicação com um medidor de semente. um aparelho de seleção restringe o medidor de semente para depositar apenas uma dentre as fontes de entrada de tal modo que se permita que o medidor de semente alterne entre depositar a primeira e a segunda entradas. o conjunto de circuitos de processamento controla o aparelho de seleção para alternar entre a primeira e a segunda entradas.
