Beerkan infiltration experiments with three water pouring heights (low, L = 3 cm; intermediate, M = 100 cm; high, H = 200 cm) were performed on both a no‐tilled (NT) and a conventionally tilled (CT) bare loam soil to determine the surface soil hydraulic properties by the BEST‐steady algorithm. Saturated soil hydraulic conductivity, K_s, significantly and monotonically decreased from the L to the H runs (from 236 to 37 mm h^‒1) and lower K_s values were detected under CT (163–23 mm h^‒1) than NT (346–51 mm h^‒1) for each water pouring height. For both soil management practices, the gravitational potential energy, E_p, of the water used for the infiltration runs, explained most of the variance in the mean K_s values. According to the fitted relationships, an increase of E_p from 50 to 3,327 J m^‒2 determined a K_s decrease by a factor of 9.5 in the CT soil and 6.3 in the NT soil. The CT soil was 2.1 and 3.3 times less conductive than the NT soil with the lowest and the highest energy, respectively. The water retention scale parameter, h_g, only varied between non‐perturbing (L) and perturbing (M, H) runs because |h_g| increased from 55 to 93–100 mm. Therefore, water impact can greatly influence hydrodynamic properties of the upper soil layer regardless of the management practice. The tested infiltration methodology looks promising to mimic effects of relatively high energy rainfall events and to determine the hydraulic properties of the exposed soil layer under different management practices.

改进的Beerkan运行方法，以评估水分对常规耕种和免耕条件下壤土渗透性和水力特性的影响

在不倾斜（NT）和常规耕作（CT）的裸壤土上进行了三个注水高度（低，L = 3厘米;中，M = 100厘米;高，H = 200厘米）的Beerkan渗透实验通过BEST-steady算法确定土壤表层的水力特性。饱和土壤导水率，ķ_小号，显著和单调从L下降为H运行（从236到37毫米高^-1），并降低ķ_小号CT下被检测到的值（163-23毫米高^-1）比NT（每个注水高度为346–51 mm h ^‒1）。对于两种土壤管理实践，重力势能E _p渗透用水中的，解释了平均K _s值的大部分变化。根据拟合关系，E _p从50增加到3,327 J m ^‒2决定了CT土中K _s降低9.5倍，而NT土中K _s降低6.3倍。CT土的电导率分别是能量最低和最高的NT土的2.1倍和3.3倍。保水规模参数h _g仅在非扰动（L）和扰动（M，H）之间变化，因为| ^ h _{g ^}| 从55毫米增加到93-100毫米。因此，无论采取何种管理措施，水的冲击都会极大地影响上层土壤的水动力特性。经过测试的渗透方法看起来有望模拟相对较高能量的降雨事件的影响，并在不同的管理方法下确定裸露土壤层的水力特性。
