ABSTRACT:
A grain drill having a plurality of closely spaced seeding units is modified to change the pattern of seed flow through one of the seeding units cyclically within the length of a row, so that when the plants emerge, the one row will be visibly different from the other rows. The visibly different row can then be used as a marker for weed control spraying or the like.
