I don't have any real 'pure' clover plots, but I am planning to do something for next season.
man, i've caught myself saying that before!!! lol, i still haven't seen a "pure" stand of clover --- matter-of-fact, i don't think they exist!!!
i broadcasted inoculated ladino clover at a rate of 3-4lbs per acre (coop guys tell me i'm overseeding)... if my math is correct you have 2 lbs of clover seed in a 50lb consisting of 4% clover, plus 48lbs of additional seed to add a little variety to the food buffet.......
i planted plots last weekend that consist of ladino, ladino w/ rye, and red clover w/ p.t. turnips..... best of luck!
