Activation and deactivation of the seed disks within the seed meter are synchronized to selectively deliver a single one of the multiple types of seed from the respective seed meter chamber for delivery out of a single seed tube of the seed meter, which may provide absolute and instantaneous on-the-go seed switching within a single row from each seed meter. ## Claims ### Claim 1 A planter for planting multiple types of seed in a single planting pass during row-crop planting of an agricultural field, comprising: a frame; a bulk storage system supported by the frame and configured for storing multiple types of seeds; multiple row units supported by the frame, each of the multiple row units including, an on-row storage system with multiple compartments configured to receive respective ones of the multiple types of seed from the bulk storage system; and a seed meter for planting the multiple types of seed and including a housing having multiple portions defining multiple seed chambers respectively receiving seeds of multiple types from the multiple compartments of the on-row storage system and multiple seed disk assemblies for selectively delivering individual seeds of the multiple seed types from the multiple seed chambers of the seed meter out of the housing for release onto an agricultural field during row-crop planting of the agricultural field. ### Claim 2 (depends on 1) The planter of claim 1 wherein the multiple portions of the housing of the seed meter include, a first portion defining a first seed chamber for receiving seeds of a first type; a second portion defining a second seed chamber for receiving seeds of a second type; a third portion defining a third seed chamber for receiving seeds of a third type; and a fourth portion defining a fourth seed chamber for receiving seeds of a fourth type. ### Claim 3 (depends on 2) The planter of claim 2 wherein at each row unit, the multiple compartments of the on-row storage system are defined by multiple mini-hopper chambers of a mini-hopper arranged to deliver seeds to the seed meter, the multiple mini-hopper chambers including, a first mini-hopper chamber arranged to deliver seeds of the first variety to the first seed chamber of the seed meter; a second mini-hopper chamber arranged to deliver seeds of the second variety to the second seed chamber of the seed meter; a third mini-hopper chamber arranged to deliver seeds of the third variety to the third seed chamber of the seed meter; and a fourth mini-hopper chamber arranged to deliver seeds of the fourth variety to the fourth seed chamber of the seed meter. ### Claim 4 (depends on 3) The planter of claim 3 further comprising a diverter configured to selectively direct seeds of the first, second, third, and fourth type to respective ones of the first, second, third, and fourth mini-hopper chambers. ### Claim 5 (depends on 4) The planter of claim 4 wherein the diverter includes diverter outlet ducts and a gate system having gates actuatable to close or open the outlet ducts of the diverter to respectively block or permit flow through passages extending through the outlet ducts into the first, second, third, and fourth mini-hopper chambers. ### Claim 6 (depends on 5) The planter of claim 5 wherein the diverter is mounted with respect to the mini-hopper with the diverter outlet ducts connected to inlets of the first, second, third, and fourth mini-hopper chambers. ### Claim 7 (depends on 5) The planter of claim 5 wherein the diverter is arranged upstream with respect to the mini-hopper and is connected to a primary seed conduit receiving seeds from the bulk storage system, the diverter outlet ducts connected to secondary seed conduits extending from the diverter outlet ducts to respective ones of inlets of the first, second, third, and fourth mini-hopper chambers. ### Claim 8 (depends on 3) The planter of claim 3 wherein the multiple seed disk assemblies include a first seed disk rotatable within the housing for conveying seeds of the first seed type through the housing, a second seed disk rotatable within the housing for conveying seeds of the second seed type through the housing, a third seed disk rotatable within the housing for conveying seeds of the third seed type through the housing, and a fourth seed disk rotatable within the housing for conveying seeds of the fourth seed type through the housing. ### Claim 9 (depends on 8) The planter of claim 8 wherein the first and second seed disks define a first pair of the seed disks generally transversely aligned and arranged at an angle with respect to each other and the third and fourth seed disks define a second pair of the seed disks generally transversely aligned and arranged at an angle with respect to each other, and wherein the first and second pairs of seed disks converge toward each other over a seed tube configured for receiving seeds released from each of the first, second, third, and fourth seed disks. ### Claim 10 A planter for planting multiple types of seed in a single planting pass during row-crop planting of an agricultural field, comprising: a frame; a bulk storage system supported by the frame and configured for storing multiple types of seeds; multiple row units supported by the frame, each of the multiple row units including, a seed meter wherein the seed meter includes a housing having multiple portions defining multiple seed chambers receiving seeds of multiple types from the bulk storage system, multiple seed disks arranged with respect to the multiple seed chambers for delivering individual seeds out of the housing of the seed meter and a seed disk drive system configured for selectively activating or deactivating the multiple seed disks to selectively deliver a corresponding one of the multiple seed types from the housing of the seed meter for release onto an agricultural field during row-crop planting of the agricultural field. ### Claim 11 (depends on 10) The planter of claim 10 wherein the multiple seed disks include a first seed disk rotatable within the housing for conveying seeds of a first seed type through the housing, a second seed disk rotatable within the housing for conveying seeds of a second seed type through the housing, a third seed disk rotatable within the housing for conveying seeds of a third seed type through the housing, and a fourth seed disk rotatable within the housing for conveying seeds of a fourth seed type through the housing. ### Claim 12 (depends on 11) The planter of claim 11 wherein the first and second seed disks define a first pair of the seed disks generally transversely aligned and arranged at an angle with respect to each other and the third and fourth seed disks define a second pair of the seed disks generally transversely aligned and arranged at an angle with respect to each other, and wherein the first and second pairs of seed disks converge toward each other over a seed tube configured for receiving seeds released from each of the first, second, third, and fourth seed disks.
