One last try
I really need that .05. Could you be refering to Nickle. Cause if I've heard right some folks think it is used with the urease enzyme to break down urea into ammonium and carbon dioxide preventing toxic levels of urea to accumulate in legumes. In grains I think it has been shown to be esential for certain enzymes which are involved grain filling and seed vialiblilty. Man you sure do make a guy work for a .05.
