Response of ammonia volatilization to biochar addition: A meta-analysis

Science of the Total Environment, 2019
There has been increasing interest in and use of biochar as a soil amendment. However, the effects of biochar addition on ammonia volatilization (AV) appeared contradictory from the many reported studies and the main influencing factors remain unclear ...

Effects of soil properties on ammonia volatilization [PDF]

Soil Science and Plant Nutrition, 2000
Abstract By using a small culture dish located above a large-sized closed dish with soil samples to trap emissions as well as applying multivariate analysis methods, the influence of soil properties on ammonia volatilization and their correlation was studied.

Nitrification inhibitors and ammonia volatilization

Plant and Soil, 1971
A nitrification inhibitor applied with ammonium sulphate to bare soil and to grass increased the persistence of ammonium-N in soil and decreased the amount of nitrate-N leached from bare soil. Ammonia was volatilized more rapidly from bare soils treated with ammonium sulphate plus the inhibitor than when ammonium sulphate alone was used; the inhibitor ...

Volatilization of ammonia

1983
Ammonia is ubiquitous in Nature, being formed from the biological degradation of proteins in soil organic matter, plant residues and animal wastes. Its presence is readily detectable near barns, stables and feedlots where plant and animal residues are concentrated but it is also formed in many other situations from less concentrated sources, e.g.

Ammonia volatilization from Vertisols

European Journal of Soil Science, 2002
Summary Farmers want to minimize losses of nitrogen (N) by volatilization of ammonia when adding fertilizers and improve fertilizer recovery of N by plants. We aimed to quantify the losses of N through NH 3 volatilization as affected by soil moisture content, type of ...

Ammonia Volatilization from Senescing Leaves of Maize

Science, 1979
Ammonia release by plants growing in normal air is reported. Contrary to observations made at high ambient ammonia concentrations, corn plants did not absorb ammonia in normal air but released it as they senesced, even while photosynthesizing actively.

Relationships between Ammonia Volatilization, Ammonia Concentration and Water Evaporation

Soil Science Society of America Journal, 1964
Abstract The rate of NH 3 volatilization and the rate of water evaporation from soils followed different functions. These functions were not affected by differences in soil texture, soil water, speed, or relative humidity of air flowing over the soil surface.

Water-manure interactions on ammonia volatilization

Biology and Fertility of Soils, 1994
The integrated horizontal flux method was used to determine NH3 volatilization from surface-applied swine manure (Sus scrofa domesticus). This method allows simple NH3 flux estimates to be made from small source plots based on a measurement of windspeed and NH3 concentration at a single sampling height.

Ammonia volatilization from sows on grassland

Atmospheric Environment, 2001
Abstract According to regulations, sows with piglets on organic farms must graze on pastures. Volatilization of ammonia (NH 3 ) from urine patches may represent a significant source of nitrogen (N) loss from these farms. Inputs of N are low on organic farms and losses may reduce crop production.
