Nitrification inhibiting compositions and their use in agricultural applications
A nitrification inhibiting composition for use in agricultural applications includes from about 5% to about 15% propylene glycol methyl ether and from about 20% to about 35% dicyandiamide. The nitrification inhibiting composition may be combined with a fertilizer and applied to plants or soil to increases the effectiveness of the fertilizer, thereby positively impacting crop yield and quality.

2. The nitrification inhibiting composition of claim 1 further comprising from about 5% to about 20% propylene glycol.
3. The nitrification inhibiting composition of claim 1 further comprising from about 50% to about 80% dimethyl sulfoxide.
4. The nitrification inhibiting composition of claim 1 containing dicyandiamide in an amount from about 29% to about 32%.
5. The nitrification inhibiting composition of claim 1 further comprising a urease inhibitor.
6. A fertilizer composition comprising:
a nitrification inhibiting composition as in claim 1 ; and
a fertilizer.
7. The fertilizer composition of claim 6 wherein the fertilizer is a liquid fertilizer.
8. The fertilizer composition of claim 6 wherein the nitrification inhibiting composition used to formulate the fertilizer composition further includes from about 5% to about 20% propylene glycol.
9. The fertilizer composition of claim 6 wherein the nitrification inhibiting composition used to formulate the fertilizer composition further includes from about 50% to about 80% dimethyl sulfoxide.
