(2016) compared the effects of untreated urea and urea coated with either DMPP (ENTEC[R]), nitrapyrin (eNtrench[TM]) or a 4-month release polymer (CoteN[TM]), on [N.sub.2]O emissions, sorghum yield and N use efficiency (NUE).
DMPP allows nitrogen to stabilize as [NH.sup.+.sub.4] for an eight-week period in the soil by inhibiting the conversion of ammonium into nitrate to reduce N losses.
The contribution of GG, a polycolloidal polymer, resulted with controlled release of DC from DMPP to reach a maximum concentration in plasma.
This article highlights an important and growing issue identified from the DMPP research.
This biosynthesis begins with the addition of IPP to dimethylallyl pyrophosphate (DMPP) to forro a trans-, trans-, trans-geranylgeranylpyrophosphate.
An unfertilised control and five N-fertiliser treatments were established for each soil type, and are identified as: (i) nil; (ii) standard urea granules; (iii) standard urea granules treated with liquid nitrapyrin (eNtrench[TM]); (iv) 3,4-dimethylpyrazole phosphate (DMPP) coated on standard urea granules (ENTEC[R]); (v) 3,4 dimethyl pyrazole glycolate (DMPG) coated on standard urea granules with proprietary solvent or wetting agent for improved inhibitor retention on the fertiliser granule; and (6) polymer-coated urea (PCU) granules (Agromaster Tropical[R]) with an approximate release period of 90 days (determined by the industry standard method of dissolution in water at a constant temperature).
Nitrification inhibitors at a glance: A number of compounds like dicyandiamide (DCD), nitrapyrin and 3,4-dimethylpyrazole phosphate (DMPP) have been reported to inhibit the nitrification process in soils (Zerulla et al., 2001; Gioacchini et al., 2002; Majumdar et al., 2002; Irigoyen et al., 2003) andreduce nitrous oxide emissions and nitrate leaching (Zaman andBlennerhassett, 2010).
Iron oxide, [Fe.sub.3][O.sub.4], 20-50 nm (Sigma-Aldrich), 2,2-dimethoxy-2-phenylacetophenone, DMPP (Sigma-Aldrich), poly(vinyl alcohol), and PVA (Sigma-Aldrich) were selected as the photo initiator and stabilizer, respectively.
