<p>Thanks. I'm trying to go commercial and thinking I really need the organic certification if I am to make money, at least for selling to whole foods and such. Selling locally I'm pretty sure the people around here don't care, but 60 miles away in Austin Organic is the big thing.</p>
<p></p>
<p>Leads me to a second question, how do you test for iron and what should the levels be?</p>
<p></p>
<p>Thanks</p>

<p>Right. As with many items, there are specific protocols to follow under NOP rules.</p>
<p>I was just trying to address question of 'are there other OMRI approved sources of iron'...I run across many gardeners who aren't in the NOP in terms of obtaining Organic certification...but do look for the OMRI label when purchasing inputs <img src="http://www.bkserv.net/images/Smile.gif"/></p>

<p>Before the advent of synthetic chelates, hydroponicists used to utilize ferrous sulfate as a source of iron in their nutrient solutions. It is non-synthetic and allowed by OMRI when used as a "Crop Fertilizer or Soil Amendment".</p>
<p></p>
<p>It is also not chelated, so using it in high pH systems may not be a 'winning strategy'...but it is an OMRI approved source of iron. </p>

Is there an omri approved iron that works better? Thanks

Ha!! even worse!! im using the biomin liquid iron.. and your right, it doesn't hold up at all, the system with the higher ph is ugly as all get out... im going back to the sprint 330(works in high ph). the liquid biomin is great for foliar spraying.

<p>Rob - are you using that Biomin powdered iron? I hate to break it to you, but that product is very very weakly chelated. It's chelated with citric acid, which is 7 times less stable than Fe-EDTA, and loses all stability over a pH of 6.3ish. So the plants aren't using it all up - it's just falling out of suspension.</p>
