| Cultivation generally increases net nitrification through liming, aeration, enhanced ammonium levels, and lower immobilization. |
|
| These conditions raise the potential for nitrification, leaching, denitrification, or runoff losses. |
|
| Dr. Miiller recognised the necessity for zoetic nitrification on well-aerated filter-beds composed of coke breeze, sand, and kindred substances. |
|
| Soil nutrients and nitrification appeared to vary more by land use in hardwood stands than in conifer stands. |
|
| Greenhouse nitrous oxide release, which results from fertiliser and pulse crop nitrification, remains the subject of ongoing research. |
|
| As a whole, the mineralization and nitrification of nitrogen in the manual loessial soil was higher than that in the red loessial soil. |
|
| A dynamic model takes into consideration rapid chemical reactions, eg chemical weathering, nutrient uptake and nitrification. |
|
| Although nitrification was detected for at least one time period in all sites, substantial nitrification occurred only in the hardwood cultivated sites. |
|
| In severe cases, some utilities switch to free chlorine for a short period of time to mitigate nitrification. |
|
| Current research has shown an increase in soil acidification through anthropogenic effects including acid precipitation and nitrification of ammoniacal fertilizers. |
|
| Any increase in export production will inevitably increase nitrification and associated nitrous oxide production. |
|
| Refer to report for other substances listed as having an inhibitory effect on anaerobic digestion and nitrification processes. |
|
| By the use of chloramines, nitrification can take place in the distribution network. |
|
| Emissions of nitrous oxide from agricultural soils are primarily due to the microbial processes of nitrification and denitrification in the soil. |
|
| It is difficult to predict how many facilities will need to upgrade to nitrification across Canada at this time. |
|
| Upgrading wastewater facilities to allow for nitrification to reduce ammonia content is a major cost. |
|
| Urease inhibitors are used to slow the hydrolytic conversion of urea into ammonia, which is prone to evaporation as well as nitrification. |
|
| Myers RJK Temperature effects on ammonification and nitrification in a tropical soil. |
|
| The efficacy of DCD as a nitrification inhibitor will depend on its concentration and persistence in the soil. |
|
| The formation is either through nitrification or denitrification or nitrifier denitrification or combination of all these three processes. |
|
|
|
| However, some local maxima were observed probably due to bioturbation and local nitrification processes. |
|
| As recovery of nitrifying bacteria can be very slow, nitrification may be inhibited for a considerable period of time, thus increasing ammonium in fumigated soils. |
|
| Simultaneous nitrification and denitrification with an upflow fixed bed reactor applying clinoptilolite as media. |
|
| The steps, which are not altogether sequential, fall into the following classifications: nitrogen fixation, nitrogen assimilation, ammonification, nitrification, and denitrification. |
|
| The use of inorganic or organic polyacids for the treatment of inorganic fertilizers in powder form or in granule form which contain a nitrification inhibitor. |
|
| These tests include potential nitrification, basal respiration, substrate-induced respiration, heterotrophic nitrogen-fixation and dehydrogenase activity assays. |
|
| This technique is designed to promote biological activity that speeds up the bio-degradation of putrescible materials and causes nitrification of the ammoniacal nitrogen and thus denitrification of the nitrates. |
|
| The main purpose of this study is to investigate the application of novel gas-permeable membrane bioreactors for cost-effective nitrification and denitrification in wastewater. |
|
| The gas is a by-product of the biological denitrification process in anaerobic environments and of the biological nitrification process in aerobic environments. |
|
| The wastewater is discharged into the public sewage system and treated in the municipal wastewater treatment plant, which is a biological plant with nitrification and denitrification. |
|
| In a process called nitrification, or nitrogen fixation, bacteria such as Rhizobium living within nodules on the roots of peas, clover, and other legumes convert diatomic nitrogen gas to ammonia. |
|
| Rapid methods for measuring nitrification rates will assist operators to optimize the removal of ammonia by allowing them to react more quickly to changing conditions in their treatment process. |
|
| In most of this acid soil, biological activity is much reduced and this slows down the decomposition of plant debris and the nitrification process. |
|
| Increased nitrification and dentrification capacities are important factors in waste water treatment and logically connected to reduced costs for volume activations and dentrification. |
|
| As an engineer, Zinger has developed a biological filter with plants with dense roots and a natural substrate propituous for the development of nitrification bacteria and anti-phosphorus. |
|
| The principle pathway for nitrification may have been nitrifier denitrification. |
|
| Urea formaldehyde condensation product nitrification by AOB is very slow resulting in the controlled release of nitrates. |
|
| Uncontrolled nitrifier sloughing causes nearly complete nitrification loss and rapid ammonia level increases unless fish feeding rates are immediately curtailed. |
|
| Nitrification cannot occur in the presence of oxygen, so nitrogen is fixed in specialized cells called heterocysts. |
|
| Nitrification by Nitrobacter agilis on surfaces and in soil with respect to hydrogen ion concentration. |
|
|
|
| Nitrification occurs as ammonium ions adsorbed to media and biofilms during the flooded phase rapidly nitrify upon exposure to atmospheric oxygen during the drained phase. |
