Good on you for going organic cga, I don't know what 46-0-0 is but if it is any thing like super phosphate I would avoid it like the plague here is an exert from a book called organic gardening by Peter Bennettcga wrote:I use to plant 6 acres with chemical fertalizers on different ground, but at my house I want to go strictly organic. I will admit I did use what 46-0-0 I had left over on my corn, but that was the end of it for me.
Declining pastures, induced trace element deficiencies, animal health problems and environmental hazards including serious pollution of waterways and estuaries are undoubtedly resulting from the overuse of superphosphate and should be the concern of every well-informed and decent citizen. - Peter Bennett
