Abstract
An improved seed marker tab comprising an elongated flat tab element proportioned to have one end thereof inserted in the soil to a predetermined level with the other end thereof projecting above the soil. The tab is formed of stiff, relatively thin, self-supporting material and the end portion that is inserted in the soil has preferably an indentation or pod formed in one end thereof. Openings provided at the back of the pod for receiving seeds specifically determine number and location of seeds mounted on the tab. Filler material covers the seeds overlying the openings to complete the assembly. The improved seed marker tab results from a new process whereby vacuum means are used to hold the seed in place while the tab assembly is completed.
