Soil Compaction Analyzer

The Soil Compaction Analyzer is a soil moisture monitoring system consisting of a handheld data logger and a compaction sensor. It offers the advantages of easy operation, portability, and rapid, reliable testing, making it a standout in its field. The handheld data logger can be factory-configured with GPS and GPRS data upload functions according to user requirements. Data from the device can also be transferred to a computer via a USB data cable, and historical data can be exported to the computer for analysis.

Soil compaction, also known as soil hardness, soil firmness, or soil penetration resistance, is typically measured by the resistance encountered when a metal plunger or probe is pressed into the soil (unit: Pa). Soil compaction refers to the soil's ability to resist compaction and fragmentation under external forces, which is one aspect of soil properties. Additionally, soil physical properties include soil texture, structure, porosity, etc., which relate to soil firmness, plasticity, permeability, drainage, water retention capacity, and the ease of root penetration.

Soil compaction is composed of soil shear strength, compressive strength, and friction strength, among others. It serves as a composite indicator of soil strength. When a metal plunger or probe is pressed into the soil, two methods are used: dynamic loading and static loading. The measured values differ between the two methods but are related. The shape of the plunger can be conical, flat-headed, spherical, or wedge-shaped, and these shapes also affect the measured values. For the same method, the measured values are primarily determined by soil texture, bulk density, and moisture content, with moisture content having the greatest influence.

Soil compaction can predict soil bearing capacity, tillability, and resistance to root growth. The degree of soil compaction affects crop root penetration and growth, making it an important soil physical property indicator used to evaluate soil tillability. Compacted soil can prevent water infiltration, reduce fertilizer utilization, impair plant root growth, and lead to reduced crop yields.
