When I was looking for a source for a liquid calcium product, I came across this info:
Fertilizers, growth promoters and soil amendments prohibited for use
in organic crop production include but are not limited to the
Fortified humic acid derivatives
Growth regulators, synthetic
Human sewage sludge
Leather meal or tankage
Muriate of potash
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?
