Loess soils are assumed to be light textured with higher nitrification activity, which makes them susceptible to excessive nitrogen losses. I am not sure whether the statement is true, needs clarity and justifications.

Effects of urease and nitrification inhibitors added to urea on nitrous oxide emissions from a loess soil
Urea fertilizer-induced N2O emissions from soils might be reduced by the addition of urease and nitrification inhibitors. Here, we investigated the effect of urea granule (2–3 mm) added with a new urease inhibitor, a nitrification inhibitor, and with a combined urease inhibitor and nitrification inhibitor on N2O emissions. For comparison, the urea granules supplied with or without inhibitors were also used to prepare corresponding supergranules. The pot experiments without vegetation were conducted with a loess soil at (20 ± 2)°C and 67% water-filled pore space. Urea was added at a dose of 86 kg N ha–1 by surface application, by soil mixing of prills (
