What is Comparison of Chemical Methods of Assessing Potentially Available Organic Nitrogen in Soil about?
We recently developed two rapid and precise chemical methods of assessing potentially available organic Ν in soils. One method involves determination of the ammonia-N produced by steam distillation of the soil sample with pH 11.2 phosphate-borate buffer solution for 8 min. The other involves determination of the ammonium-N produced by treatment of the soil sample with 2M KC1 solution at 100°C for 4 hours. Studies using 33 Brazilian soils showed that the results obtained by these methods were highly correlated with those obtained by anaerobic and aerobic incubation methods of assessing potentially available organic Ν in soil. The two methods were further evaluated by applying them to 30 Iowa soils and by comparing their results and those obtained by other chemical methods with the results of the incubation methods considered to be the best laboratory methods currently available for assessment of potentially available organic Ν in soil.
