Claim:
1. A method of using a particulate material delivery system to pneumatically dispense seed to an agricultural field, the method comprising: delivering product from a storage compartment to a metering system having multiple metering units; individually controlling the delivery rate of product through each of the multiple metering units; receiving separate portions of product from each of the multiple metering units and distributing the separate portions of product delivered from each of the multiple metering units to multiple distribution lines arranged for pneumatic delivery of the separate portions of product to the agricultural field; controlling an airflow characteristic of an airflow that entrains the product based on the delivery rate of at least one of the multiple metering units for pneumatically conveying product from each of the multiple metering units, through corresponding multiple distribution lines, toward multiple opener units of a drill for delivering product at multiple locations of an agricultural field corresponding to the locations of the multiple opener units of the drill; and separately controlling delivery rate of the product to at least some of the multiple locations of the agricultural field by individually controlling the delivery rate of product through each of the multiple metering units and the corresponding multiple distribution lines, and controlling the airflow characteristic.
