Potassium, nitrate and ammonium concentrations and fluxes showed dramatic responses to hurricane disturbance.
Ammonium and nitrate were extracted before and after the incubation as described above.
Nitrogen was quite low compared to other species, and it was essentially supplied in the form of ammonium and amino acids.
One bit of information is from the quaternary ammonium ions and their entry and escape rates through this gate in the open and closed states.
Simulations were performed in three different scenarios of availability of ammonium and oxygen, to evaluate the evolution of the three microbial species present.
The post-1996 wheat crop samples were also analysed for exchangeable bases (ammonium acetate extraction) and cation exchange capacity (potassium chloride).
Treatments include ammonium nitrate (closed circles), sulphur-coated urea (open circles), composted dairy manure (closed triangles), and poultry litter (open triangles).
During that time period, the ammonium loss from sulphur-coated urea was significantly greater than that measured from the composted dairy manure.
