1. A combination comprising:
an air seeder, comprising:
a controller;
a first source of a first product, the first source comprising a first gate;
a second source of a second product, the second source comprising a second gate;
a first distribution assembly configured to receive the first product from the first source;
a second distribution assembly configured to receive the second product from the second source;
an air source configured to provide a combined product from the first and second distribution assemblies to a first metering module, the combined product comprising the first product and the second product; and
a dispensing section comprising:
a plurality of seeding units;
the first metering module being in communication with the controller and the first and second product distribution assemblies and configured to control a flow of the combined product-to the plurality of seeding units; and
a sensor in data communication with the controller and configured to detect the combined product passing through at least one of the plurality of seeding units;
wherein the controller is configured to:
control the first gate to control flow of the first product from the first source to the first distribution assembly;
control the second gate to control flow of the second product from the second source to the second distribution assembly; and
determine a dispense activation delay for the dispensing section by measuring a delay between activation of the first metering module and the sensor detecting the combined product arriving, and to control the first metering module based upon the dispense activation delay; and
a tractor coupled to the air seeder and configured to pull the air seeder through an agricultural field, wherein the tractor comprises:
a third source of a third product; and
a delivery tube through which the third product flows from the third source to the air seeder.
