Humic Acids – alkali extracted
Allowed
Crop Fertilizers and Soil Amendments, Crop Management Tools and Production Aids
Synthetic
Also called humic acid derivatives. Extracts from nonsynthetic humates by hydrolysis using synthetic or nonsynthetic alkaline materials are permitted. Includes humates that are extracted using potassium hydroxide and ammonium hydroxide, provided that the synthetic extractant is limited to that amount necessary for extraction and is not used to fortify the potassium or nitrogen analysis. See also HUMIC ACIDS – NONSYNTHETIC. Some humic acid derivatives may be used both as an adjuvant or inert ingredient in EPA registered and exempt pesticides. See also INERTS – LIST 4.
