System and method for dispensing agricultural products while synchronizing seed placement

A system for dispensing agricultural products, comprising:

• at least one source of agricultural product;
• at least one agricultural product tube operatively connected to said source of agricultural product;
• a seed sensing device configured to control the delivery of said agricultural product;
• a metering system operatively coupled to said at least one agricultural product tube and to said seed sensing device and configured to synchronize the placement of at least one agricultural product relative to the placement of seed;
• and,
• a sensor assembly, comprising:
• a signal conditioning circuit configured to provide an output signal representing an indication of the presence of said agricultural product and at least one seed for use in determining the synchronized placement of seed and said agricultural product in correct proximity with one another in a seed furrow;
• wherein the presence of both a seed mass component and an agricultural product mass component of the output signal defines a package mass;
• and,
• wherein said output signal has a pre-defined value and is transmitted to a controller to determine whether there is an error;
• wherein said error corresponds to a failure of the controller to detect a signal consistent with the presence of both a seed and agricultural product passing through the sensor assembly as the package mass;
• wherein said controller is configured to generate an error signal that is capable of being displayable on a remote display/user interface system that can be monitored by the system operator;
• and
• wherein synchronized delivery of liquid with seed results in strips of untreated soil in the furrow in the space between each planted seed.
