Abstract
Reaction products and methods for making and using the same are provided. The reaction products particularly may include adducts of two or more reactants. The adducts particularly can incorporate a nitrification inhibitor, such as DCD. In particular embodiments, reaction products may be formed from the reaction of formaldehyde, DCD, urea, and an ammonia source. The adducts may be included in agricultural products, including fertilizer compositions and nitrification inhibitor systems. Fertilizer compositions including the adducts can be beneficial for reducing leaching of nitrification inhibitors applied to soil.
Claims20
An agricultural composition comprising:
- A) a material selected from the group consisting of urea, dicyandiamide (DCD), urea-formaldehyde polymer (UFP), ammonia, and combinations thereof;
- B) at least one adduct according to the structure of Formula 4
- wherein:
- X is O or
- R1, R2, R3, and R4 are independently selected from the group consisting of:
- and
- wherein, if X=O,
- at least one of R1, R2, R3, and R4 is
- and
- C) a urease inhibitor.
A nitrification inhibitor system comprising a mixture of:
- a. a triazonyl-formaldehyde-DCD adduct;
- b. a urea-formaldehyde-DCD adduct;
- and
- c. a urease inhibitor.
A method for reducing nitrification in soil, the method comprising:
- applying an agricultural composition to the soil such that nitrification of a nitrogen source in the soil is reduced, wherein the agricultural composition comprises:
- A) a material selected from the group consisting of urea, dicyandiamide (DCD), urea-formaldehyde polymer (UFP), ammonia, and combinations thereof;
- B) at least one adduct according to the structure of Formula 4
- wherein:
- X is O or
- R1, R2, R3, and R4 are independently selected from the group consisting of:
- and
- wherein, if X=O,
- at least one of R1, R2, R3, and R4 is
- and
- C) a urease inhibitor.
