The utilization of enzyme inhibitors dicyandiamide
and N-(n-butyl) thiophosphoric triamide does not change the contents of soil microbial phosphorus, regardless of being applied along with either mineral or organic source of nutrients.
BFTDA was obtained via a low-cost one-pot 2 + 3 cycloaddition of dicyandiamide
on nitrile groups (Scheme 1) with simple purification steps and high yield (90%).
Herein, we for the first time developed a bottom-up strategy to synthesize g-[C.sub.3][N.sub.4] photocatalysts with improved optical property and chemical structure through using disordered dicyandiamide
(D-DCDA) as reaction precursor.
, or DCD, is added to pastures to reduce the amount of greenhouse gases emitted by dairy herds.
Comparison of the effectiveness of a nitrification inhibitor, dicyandiamide
, in reducing nitrous oxide emissions in four different soils under different climatic and management conditions.
Chemicals used were PAE CA 1920 (Ashland Water Technologies, Wilmington, Delaware), urea, dicyandiamide
, sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide (CTAB), and 1,2-propanediol (propylene glycol; Sigma-Aldrich, St.

Epoxide Reaction." Macromolecules, 24 360-369 (1991)
Besides, they all required the use of dicyandiamide
, which is not always available and also has very limited solubility.
It trades in 25 types of chemicals, including citric acid, phosphoric acid, paraffin wax and dicyandiamide
. The company has marketing offices in China, from where it procures the majority of its supplies.
Mkhabela MS, Gordon R, Burton D, Madani A, Hart W (2006) Effect of lime, dicyandiamide
and soil water content on ammonia and nitrous oxide emissions following application of liquid hog manure to a marshland soil.
These chemicals are typically combined with a catalyst (dicyandiamide
, aliphatic diamines or aromatic amines) at an elevated temperature to initiate the reaction.
