Soil Nh 4 N A No 3 N B No 2 N C And Don D Ratio of soil nh 4 n, no 3 − n, and soil inorganic nitrogen (sin) contents to their initial values during the incubation period under different salinity, freezing thawing. Ammonium nitrogen (nh 4 n) ammonium nitrogen usually does not accumulate in the soil, as soil temperature and moisture conditions suitable for plant growth also are ideal for conversion of nh 4 n to no 3 n. ammonium nitrogen concentrations of 2–10 ppm are typical. soil nh 4 n levels above 10 ppm may occur in cold or extremely wet soils, when the soil contains fertilizer from a recent.
Figure A1 Ratio Of Soil Nh 4 N No 3 N And Soil Inorganic Concentrations of nh 4 and no 3 are typically expressed as element mass of n per gram of dry soil, but conversion to an areal basis is possible if the soil bulk density and sample depth are known. On the day of destructive soil mesocosm sampling, 10 g of the moist soil was subsampled and transferred to a 400 ml plastic vial. then 100 ml of a 2 m kcl solution was added to each vial (a 1:10 ratio was used due to the expected high mineral n concentrations). Ratio of soil no 3 –n and nh 4 –n contents in all soils at different levels of soil ec and water contents after a 10 d incubation at 25°c. accumulation of soluble salts. The rate of immobilization and the amount of n immobilized by the soil microbial community is determined by the starting concentrations of nh 4 and no 3 in the soil, the amount of c added to the soil, the size of the microbial pool, and the specific microbes present in the soil.

Nh 4 n and no 3− n are among the most widely measured n species (xie et al., 2020) and account for 85% of the total n (tn) in the aquatic ecosystem (kieber et al., 2005). n species and their concentrations significantly affect the n transformation (li et al., 2017b). Nitrogen cycle nitrogen exists in the soil system in many forms and changes (transforms) very easily form one form to another. the route that n follows in and out of the soil system is collectively called the “nitrogen cycle” (figure 1). the nitrogen cycle is biologically influenced. At the end of the incubation, the efficiency of the dig treatment with respect to min reached 61% in relation to the total n supplied calculated by the ratio between 38.4 and 62.5 mg mineral. We found that 87–92% of the applied 15 n labelled nh 4 was rapidly recovered as no 3− since day 3 and only 2–4% as microbial biomass and soil organic matter (som), while ryegrass.
