additional iron

["Walter Nelson" <wnelson@freedom.cce.cornell.edu>]

for better foliage color and test results that show low iron levels
chelated iron is desirable for production of this poinsettia crop
a multiheaded injector is used
tank 1 combination sulfuric acid and phosphoric acid
tank 2 calcium and potassium nitrate in second
tank 3 excel 21-5-20
additional iron in first tank is precipitating
Will it not precipitate if put into second one too?
How about third tank?
Where might you put it?  alternate the iron with another material in one of
the  existing tanks?
Fourth head is a new purchase we want to avoid
thanks for ideas
Cheers,
