Abstract
The invention provides a synergistic composition useful as a nitrification inhibiting additive for ammonium producing fertilizers which comprises: (a) benzotriazole in the range of 2.5 to 50% (by wt % of the ammonium fertilizer), (b) metal chelating agent (cooper/nickel in the range from about 1 to 50% (by wt % of the ammonium) and ion binding compound and precursors and fertilizer.
Claims9
An agriculturally-effective fertilizer comprising an ammonium-producing fertilizer and a synergistically-effective nitrification-inhibiting additive, the additive comprising:
- (a) 2.5 to 50% benzotiazole by wt % of the ammonium-producing fertilizer and
- (b) 1 to 50% chelating agent by wt % of the ammonium-producing fertilizer,
- wherein the combination of the benzotriazole and the chelating agent provides the synergistic activity of the additive.
A synergistically-effective nitrification-inhibiting additive which comprises a 20:1 to 1:50 ratio by weight of chelating agent to benzotriazole, wherein the combination of the benzotriazole and the chelating agent provides the synergistic activity of the additive to inhibit nitrification.
