Abstract:

Nitrification is the conversion of ammonia to nitrate via nitrite and is performed by ammonia oxidising archaea (AOA), complete ammonia-oxidiser (comammox) and ammonia and nitrite oxidising bacteria (AOB and NOB). The aim of this study is to examine the effect of ammonia concentration, temperature, drought and inhibitors on activity of AOA and AOB using soil microcosms and cultures. Ammonia concentration in soil increases during drought due to the reduced soil water content and, with desiccation stress or a combination of both factors, may result in reported greater inhibition of AOA than AOB

Abstract:

Increasing pressure is being placed on the dairy industry to reduce nitrogen losses from soil. Nitrification inhibitors are a management strategy that could be implemented on dairy farms to help reduce losses of nitrogen. Nitrification inhibitors work by temporarily inhibiting the microbial conversion of soil ammonium to nitrate. Past trials have indicated that nitrification inhibitors can increase grass production and decrease nitrate leaching; however, little is known about the long-term effects on other soil nitrogen processes such as denitrification. Denitrification rates in soils can

A lag phase before growth was initiated after 1 - 2 weeks starvation, which increased to 93 - 98 h after 6 weeks of starvation. Between 1 and 6 weeks starvation the nitrifying activity per ml of recovering cell suspension decreased significantly. N. europaea was also starved in continuous flow sand and soil columns.

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 grown in one-liter containers filled with pine bark, treated with and without a nitrification inhibitor and fertilized with 210 ml of a 100 ppm NH₄-N solution. Without the inhibitor and over time, “soil” solution NH₄-N concentrations and pH decreased and NO₃-N concentrations increased. “Soil” solutio

Outcomes from this research will help growers to reduce nitrogen fertiliser application rates and reduce greenhouse gas emissions without reducing yields.

Therefore, managing chloramine decay once nitrification has triggered is challenging and often a losing battle for water utilities. Many correctiv

Abstract:

The expansion of livestock husbandry and biogas production in large parts of northwestern Germany during the last two decades increased the amount of accruing manure, as well as the demand for maize as fodder crop and substrate for biogas plants. To overcome phosphorus deficiency symptoms during early growth of maize, farmers commonly apply mineral starter fertilizers containing ammonium-nitrogen and phosphorus on top of the usual manure applications required to meet crop nutrient demand. This practice typically leads to overfertilization of N and P and the excess nutrients are then prone to b

Abstract:

Maize is the dominant crop in northwestern Germany and is mostly cultivated on sandy soils. Additionally, due to intensive livestock husbandry and biogas production, large amounts of liquid manures are produced. The current farm practice leads to high N and P surpluses at field level accompanied by environmental pollution, like nitrate leaching, eutrophication of non-agricultural ecosystems, and N2O emissions. The accruing liquid manures are often used for maize fertilization. Thereby, slurries are mainly broadcast applied using trailing hose applicators followed by incorporation into the tops
