For wheat and small grains we need the entire above ground portion of the plant analysis. As plants get to flag leaf stage we need that part of the plant. Be sure to submit a softball or double fist size of material. Do not ship in plastic lined containers or envelopes. Order supplies either on line or calling our office.
