The effect of winter grazing and a nitrification inhibitor on nitrous oxide emissions and denitrification in a stony soil
… grazing on wet soil increases the risk of denitrification and the production of the powerful greenhouse gas, nitrous oxide (N₂O). However, at the beginning of this research project, no information was available on denitrification and N₂O emission from forage crops grown in free-draining stony …

Strategies to improve crop recovery of swine manure nitrogen
… were to evaluate the effect of 1) adding a nitrification inhibitor and 2) using supplemental phosphorus (P) and sulfur (S) fertilizers as means of enhancing crop recovery of LSM-N.Field experiments were conducted at two long-term manure management sites in Saskatchewan; 1) Dixon (Black …

The potential effectiveness of eco-n nitrification inhibitor in reducing nitrification rates in a range of key New Zealand dairy pasture soils: A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science with Honours
… human health. Recent research has focussed on nitrification inhibitors as an on-farm mitigation tool to reduce nitrate leaching. This study looks at the potential effectiveness of the nitrification inhibitor eco-n at reducing nitrification rates in six different soil types from key dairying …

Inhibition of Thiobacillus ferrooxidans using antibiotics and antibacterial substances
… pyridine], used as a nitrification inhibitor in agriculture, was highly effective at concentrations greater than 0.1 ml/l. Iron oxidation levels were reduced to levels close to that in uninoculated controls (abiotic oxidation). The use of N-serve to inhibit acid mine …

No-tillage squash production on agricultural soil and minesoil
… solution (UAN), and UAN 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 …

Influence of nitrogen source and metalaxyl on nitrification in soils and the yield and quality of flue-cured tobacco
… of flue-cured tobacco, has been patented as a nitrification inhibitor. The objectives of this study were to 1) determine the influence of metalaxyl at commonly applied rates on the + nitrification of NH₄⁺ from various sources; 2) study the Influence of soil pH on inhibition of nitrification by …

The Development of Chitosan Microspheres for Use as Agrochemical Delivery or Agropollutant Adsorption Systems
… bead agrochemical delivery system for the nitrification inhibitor, dicyandiamide (DCD) and the development of a hydrogel bead adsorption system for the herbicide, paraquat. The hydrogel bead was based on the biopolymer chitosan which was protonated in order for it to be soluble in water. …

Optimization of Biological Nitrogen Removal From Fermented Dairy Manure Using Low Levels of Dissolved Oxygen
… to be used as an electron donor to fuel denitrification, and TAN at a COD:N ratio of 18:1. However, sufficient amounts of non-VFA COD was produced by the fermenter to fuel the denitrification reaction at an average NO3- removal rate of 5.3 ± 2 mg/L NO₃--N. Total ammonia N was removed from …

Evaluation of Nitrogen Sources, Starter Fertilizers, and Amendments for No-Till Corn Production
… 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 nitrate source, and 4 bu lower than …

Nitrification in a pine bark medium
The influence of nitrification on the “soil” solution of container media has not been documented. The investigation of this influence is justified since the ionic form of N in a soil solution has a significant influence on plant tissue nutrient content and growth. Three genera of woody plants were …

Characterizing biological nitrification inhibition using native Nitrosomonas europaea: mechanism studies and maize cultivar screening
… the soil through a microbial process called nitrification. In this process, ammonia-oxidizing bacteria (AOB), such as Nitrosomonas europaea, oxidize NH₄⁺ and ammonia (NH₃) to nitrite (NO₂⁻), which is further converted to nitrate (NO₃⁻) by nitrite-oxidizing microorganisms and eventually …

Nitrification inhibition by metalaxyl as influenced by pH, temperature, and moisture content in three soils
… (Pythigm spp.). Metalaxyl is also patented as a nitrification inhibitor, although not marketed for that purpose. Proper maturity and ripening of flue-cured tobacco depends on an adequate supply of N through the time of removal of the inflorescence, with a declining supply of N from that point. …

Urea fertilizer placement effects on soil greenhouse gas emissions and corn growth
… of urea fertilizer placement with and without a nitrification inhibitor (NI) on cumulative soil GHG emissions (N₂O and CO₂) and to assess the effects of urea fertilizer placement with and without a NI on plant N uptake, N use efficiency (NUE), and corn (Zea mays L.) production, on a poorly …

Optimizing nutrient availability for high-yield corn production
… synergies between nitrogen protection via a nitrification inhibitor, foliar insecticides, and a strobilurin fungicide and how they may optimize use of their resources. In-season chlorophyll ratings may provide opportunities for better final grain quality estimates. Additionally, use of …
