Nitrogen Behavior and Uptake by Corn as Affected by Time of Application, Nitrapyrin, and Supplemental Winter Heat
… of chemical nitrification inhibitors such as nitrapyrin, largely determine the amount of N lost from the soil. Field studies were conducted at Urbana, Illinois, to evaluate the effects of supplemental winter heat and nitrapyrin applied with fall and spring applications of aqua ammonia on …

Impacts of enhanced efficiency nitrogen fertilizers on yield-scaled N2O emissions in Illinois maize
… planting included anhydrous ammonia (AA), UAN + nitrapyrin, ESN, and SuperU. Gas samples were collected using static closed chambers. Soil inorganic N concentrations, soil temperature, and precipitation were monitored throughout the growing seasons. Crop N content, grain yield, and nitrogen …

No-tillage squash production on agricultural soil and minesoil
… in combination with a nitrification inhibitor, nitrapyrin. Two rates of each N source were used, the recommended rate, 80 kg N/ha, and 160 kg N/ha. Squash yields were not affected by the source of N used or by addition of nitrapyrin, but the use of N did increase yields compared to control plots …

An Integrated Approach for Nitrogen Management in Upland Cotton Production
… were N-(n-butyl) thiophosphoric triamide (NBPT), nitrapyrin, and ESN. In the first set of experiments (N placement experiments), it was found that across soil types, subsurface placement of granular N source reduced NH3 volatilization by 58 – 81% and subsurface placement of UAN reduced NH3 …

Inhibition of Thiobacillus ferrooxidans using antibiotics and antibacterial substances
… and the two antibacterial substances [N-serve(nitrapyrin) and Dicyandiamide] effectively inhibited the oxidation of Fe²⁻ ions in the medium. The kinetics of Fe²⁻ oxidation with the addition of antibiotics and the antibacterial substances was studied. N-serve [2-chloro-6-(trichloromethyl) …

Nitrification inhibition by metalaxyl as influenced by pH, temperature, and moisture content in three soils
… with those of an untreated control and a nitrapyrin standard over a seven week soil incubation period in further studies using the same soils and adjusted pH levels. Significant NO₂⁻ accumulation occurred during the first week after treatment at high pH in all soil types, with 5, 25, and …

Rice Grain Yield and Nitrogen Uptake and Ammonia Volatilization from Urea as Affected by Urea Amendment and Simulated Rainfall
… NBPT rates (0 and 0.89 g NBPT kg-1 urea), two nitrapyrin (NP) rates (0 and 572 g NP ha-1), and three simulated rainfall timings [no simulated rainfall (NOSR), simulated rainfall before N (SRBN), and simulated rainfall after N (SRAN)]. Yield was unaffected by simulated rainfall timing when rice …

Influence of nitrogen source and metalaxyl on nitrification in soils and the yield and quality of flue-cured tobacco
… effects of metalaxyl were much weaker than nitrapyrin. Nitrification was inhibited by metalaxyl only in soils where nitrification was slowed by low pH and wet conditions. In soils of high nitrifying capacity, metalaxyl did not inhibit nitrification. Nitrogen uptake was enhanced by high NO₃⁻ …

Evaluation of Nitrogen Sources, Starter Fertilizers, and Amendments for No-Till Corn Production
… amended with the nitrification inhibitor, nitrapyrin (which increased yields by 5 bu acre$\sp{-1}$). Surface-applied urea and UAN produced the same average yield, which was 6 bu acre$\sp{-1}$ lower than the nonvolatile ammonium nitrate source, and 4 bu lower than unamended anhydrous …
