Seed valve and planting method for multiple seed types

A planting machine, further comprising:

• a seed meter with a housing forming an interior space for a seed pool and a metering member, the metering member being operable to meter seed from the seed pool and discharge metered seed from the housing;
• a valve body;
• at least one seed passage between the valve body and the interior space of the housing;
• the valve body having a first-type seed inlet chamber for a first-type seed from a first-type seed bulk storage, a second-type seed inlet chamber for a second-type seed from a second-type bulk storage, a first-type temporary storage chamber for first-type seed from the seed pool and a second-type temporary storage chamber for second-type seed from the seed pool, wherein each of the first-type seed inlet chamber, the second-type seed inlet chamber, the first-type temporary storage chamber and the second-type temporary storage chamber are selectively communicable with the at least one seed passage for supplying seed to the seed pool.

A planting machine, comprising:

• a seed meter with a housing forming an interior space;
• an inlet seed passage for seed to flow into the housing;
• and
• a metering member within the housing cooperating with the housing to form a seed pool within the housing for seed and a supplemental seed chamber for seed received in the housing through the seed inlet, the metering member operable to meter seed from both the seed pool and the supplemental seed chamber and deliver metered seed for discharge from the housing;
• wherein seed is maintained in the supplemental seed chamber for operation of the seed meter when the seed pool has been evacuated.
