The Important Role of Soil Bulk Densitometer in the Study of Soil Bulk Density

What is the soil bulk density? The dry weight of the soil in unit volume is the soil bulk density, which is also an important indicator of soil compaction. It is also called the soil pseudo-specific gravity. The ratio of the weight after drying in a volume of soil to the weight of water in the same volume. Soil bulk density meter is the main instrument for the determination of soil bulk density in modern times, and its measurement results are accurate and effective.

An analysis of the soil's bulk density instrument found that the soil bulk density expressed in grams of 1 cubic centimeter of dry soil including pores was the same in value. Soils with a large amount of minerals and poor structure (such as sandy soil) have a soil volume ratio of 1.4-1.7, and soils with a large amount of organic matter and good structure (such as agricultural soil) are between 1.1-1.4. The specific volume of soil volume can be used to calculate the weight of a certain area of ​​cultivated soil layer and soil porosity; it can also be used as one of indicators of soil maturity degree, and the soil with a higher degree of ripening has a smaller volume specific gravity.

Soil bulk density is determined by the amount of soil pores and soil solids. Based on the soil bulk density, the weight of any unit soil can be calculated. The formula is: soil weight = volume × volume weight, for example, 667m2 of arable land, 0.15m thick plough layer, soil bulk density of 1.34g/cm3 (1340kg/m3, 1.34T/m3), soil weight: 667 × 0.15 × 1.34 × 1000=134067 kg. It is also possible to directly use the soil bulk density meter to measure the bulk density and to obtain the data directly to avoid calculation errors.
