After decades of searching for a rapid method to estimate the N mineralization capacity soil, there is still no consistent recommendation. It legitimate examine causes often‐conflicting results in literature. The efficacy various references that have been used as benchmarks assessing chemical and physical indices literature critically reviewed this paper. Gross consumption during waterlogged aerobic incubations were estimated wide range soils. was found equivalent 17 90 23 59% mineralized...

Abstract The biological oxidation of NO 2 ‐ is inhibited when alkaline‐hydrolyzing N fertilizers are band‐applied to soils, and may accumulate. Nitrogenous gases can be evolved with added soil. aim the work described here was determine if gaseous‐N losses could occur via chemical transformations during nitrification in soils treated NH 3 fertilizer. Evolution , O, + occurred three aqueous . Losses measured soil pH > 7.5. highest loss amounted 16.5% applied‐N (1156 µg applied/g soil) a...

Abstract When alkaline‐hydrolyzing N fertilizers are band‐applied to soils, the biological oxidation of NO 2 ‐ is inhibited and may accumulate. Nitrite can react chemically with soil organic matter become fixed, at same time nitrogenous gases be evolved. The aim work described here was study mechanisms gaseous‐N formation using 15 as a tracer, define relationship between fixation loss N. Fixation Na in five soils varying pH C content ranged from 0.6 36% applied , while not recovered varied 6...
