Corn & soybeans tissue samples we need the entire above ground portion of the the plant at seedling stage. As plants get larger we need the upper most mature leaves or trifoliate. Remember to send a sufficient amount of leaf material as suggested in the plant analysis guide or a rule of thumb would be a double fist or softball size of plant material when squeezed together. Do not ship in a plastic bag. Be sure to order you plant analysis supplied from our website or call the lab.
