Abstract

Elementary soil particles are the first soil-specific level in the soil structure hierarchy, which is also the object of the soil texture analysis. To disperse soil solids to elementary soil particles (ESP), it is necessary to break the strong bonds between particles by physical action. An effective way of physical dispersion is to treat soil suspensions with ultrasound. However, depending on the type of soil, the required energy level varies, as it is determined by the stability of the soil structure. In this work the experiment with increasing energy (from 65 to 1 101 J·mL-1) of ultrasonic dispersion at constant power equal to 32.4 W is described. Soil samples from the upper horizons of three types of loamy soils (Retisol, Phaeozem, Chernozem) were used in the experiment. For this purpose, a horn-type ultrasonic disruptor Digital Sonifier S-250D (Branson Ultrasonics, USA) with a stepped solid horn tip (13 mm) was used. It was found that the value of the total energy of dispersion Et required for complete destruction of soil aggregates to ESP depends on soil type and varies within 200–800 J·mL-1 for loamy soils with an organic matter content of 1.8–4.6 g. 100 g-1 soil. For sample preparation of soils for grain-size analysis with a subsequent determination of soil texture class according to Kachinsky classification, the value Et = 250 J·mL-1 is sufficient, as it allows obtaining the maximum amount of physical clay (<10 µm) at the minimum duration of sample preparation.

利用超声波将壤土分散成基本颗粒的能量
土壤基本颗粒是土壤结构层次中的第一个土壤特异层次,也是土壤质地分析的对象。为了使土壤固体分散到基本土壤颗粒(ESP)中,需要通过物理作用打破颗粒之间的强结合。超声处理土壤悬浮液是一种有效的物理分散方法。然而,根据土壤的类型,所需的能量水平是不同的,因为它是由土壤结构的稳定性决定的。本文描述了在32.4 W恒定功率下,超声色散能量从65 J·mL-1增加到1 101 J·mL-1的实验。试验采用三种壤土类型(雷蒂松、费厄泽姆、黑钙土)的上层土壤样品。为此,我们使用了喇叭型超声干扰器数字Sonifier S-250D (Branson Ultrasonics, USA),其尖端为阶梯状实心喇叭(13 mm)。结果表明,土壤团聚体对ESP完全破坏所需的分散总能量Et值与土壤类型有关,有机质含量为1.8 ~ 4.6 g的壤土在200 ~ 800 J·mL-1之间变化。对于用于粒度分析的土壤样品制备,随后根据Kachinsky分类确定土壤质地等级,值Et = 250 J·mL-1是足够的,因为它允许在最短的样品制备时间内获得最大的物理粘土量(<10µm)。
