Anhydrous ammonia in vegetable cropping
Anhydrous ammonia, containing 82%N, is the highest analysis nitrogen fertiliser available for commercial use. Lyons (1966) states that it has many economic advantages in handling, transporting and application over conventional nitrogen fertilisers and that the high nitrogen content, plus the fact …

Recovery of Nitrogen-15-Labeled Liquid Anhydrous Ammonia Applied to Soil
Although liquid anhydrous ammonia (LAA) is the most extensively used nitrogen (N) fertilizer in U.S. and Illinois agriculture, knowledge concerning its transformations in soil is limited. The understanding of LAA transformations and the products it forms in soil are agronomically important because …

Systems Evaluation of Shallow Anhydrous Ammonia Placements, Rates, and Timing on Maize Plant Uniformity, Yield and N Use Efficiency
… yield and nitrogen (N) efficiencies.</p> <p>Anhydrous ammonia (NH<sub>3</sub>) placement during pre-plant application is of interest because of concerns for possible NH<sub>3</sub> toxicity to maize seedlings when high NH<sub>3</sub> rates are applied too close to the seed row. Traditional …

Characterization of chemically fixed nitrogen-15-labeled liquid anhydrous ammonia and of biologically immobilized nitrogen-15 in typical Illinois mollisols
… and further transformation of fixed liquid anhydrous NH$\sb3$ with emphasis on chemical fixation of NH$\sb3$ by soil organic matter. For this purpose, $\sp{15}$N-labeled liquid anhydrous NH$\sb3$ was injected into a Drummer soil. The fixed $\sp{15}$NH$\sb3$ was sequentially extracted with …

Protein preservation and rumen degradability of ensiled forage, previously treated with microwave or steam heat, formic acid, or anhydrous ammonia
… 2, steaming was compared to formic acid and anhydrous ammonia treatments for their ability to prevent proteolysis in alfalfa silages. Steamed and ensiled alfalfa also was evaluated with addition of microbial inoculant or formic acid. Silage of steamed alfalfa had greater NDIN and recovery of …

Evaluation of Nitrogen Sources, Starter Fertilizers, and Amendments for No-Till Corn Production
… yield. Highest yields came from early-applied anhydrous ammonia 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 …

Microreactors for the Production of Hydrogen From Ammonia
… high catalytic activity for the decomposition of anhydrous ammonia to nitrogen and hydrogen at moderate temperatures. Experiments involving reactor fabrication methods and optimizations of reactor catalyst support were performed. Correlations for the prediction of catalytic activity of possible …

Impacts of enhanced efficiency nitrogen fertilizers on yield-scaled N2O emissions in Illinois maize
… applied at 202 kg ha-1 at 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, …

Effect of irrigation on fertilizer nitrogen requirement, economic returns, and water availability in a corn-soybean rotation
… applied as a split application (40% preplant as anhydrous ammonia) or all at the designated time. All N except the preplant split treatment was surface applied as ammonium nitrate. Using sensors to schedule irrigation likely would have resulted in better estimate water deficit than the ET …

Synthesis, characterization and chemical vapor deposition of transition metal di(tert-butyl)amido compounds
… were grown from Mn[N(t-Bu)₂]₂ in the presence of anhydrous ammonia. The growth rate was several nanometers per minute even at the remarkably low temperature of 80⁰C. As grown, the films are carbon- and oxygen-free, and have a columnar morphology. The spacings between the columns become smaller and …
