 Post subject: Prohibited Materials
PostPosted: Fri Jun 09, 2006 8:02 am 
When I was looking for a source for a liquid calcium product, I came across this info:

Prohibited Materials

Fertilizers, growth promoters and soil amendments prohibited for use
in organic crop production include but are not limited to the

Ammonia products
Calcium nitrate
Fortified humic acid derivatives
Growth regulators, synthetic
Human sewage sludge
Hydrated lime
Leather meal or tankage
Magnesium nitrate
Mono-ammonium phosphate
Muriate of potash
Phosphoric acid
Potassium nitrate
Super phosphate
Triple phosphate
Vitamin B1

This link also shows what is allowed, and surprisingly to me;

Chilean nitrate See: sodium nitrate

Sodium nitrate Discouraged because of high sodium content. Cannot be used as the primary source of nitrogen. Sodium nitrate can be used for up to twenty percent (20%) of total nitrogen inputs. Total nitrogen is defined as pounds of nitrogen from all sources including, in part, manure, blood meal, compost, green manures, cover crops and fish meal.

Of course, this is the ingredient used in Ringer Lawn Restore. I have read else where that Chilean Nitrate is not approved for organic use.

The other surprising thing, to me, is why Vitamin B1 not allowed? Isn't that Thiamin? An ingredient of alfalfa meal and pellets?

Well, the NaNo3 ban is wierd, if it really does include the amendments you mentioned.

My guess is that they're talking about vit-B as a concentrate solution. There might be some nasty chems involved distilling it.

I don't have any use for B1 as it doesn't really help plants after transplanting. This was confirmed years ago by Sunset Magazine out of Northern CA. They found no benefits in a small controlled study. Doesn't hurt though. Just a waste of money. Best, da Shrubber
