Background: Increasing nitrogen (N) plant uptake efficiency may result in better plant quality and growth, less N susceptible to leaching and potential contamination to surrounding environments. Soil surfactants have been documented to increase water infiltration and enhance water uniformity throughout the soil profile. Thus, applying a surfactant may increase N uptake and use efficiency.

施用 15N 标记尿素的土壤表面活性剂可增加狗牙根对氮的吸收并减少氮淋失#

背景：提高氮 (N) 植物吸收效率可能会导致更好的植物质量和生长，更少的 N 易于浸出和对周围环境的潜在污染。土壤表面活性剂已被证明可以增加水分渗透并增强整个土壤剖面的水分均匀性。因此，使用表面活性剂可以增加氮的吸收和使用效率。
