◆For measurements using the same method, results are primarily determined by soil texture, bulk density, and moisture content. Among these factors, moisture content has the greatest influence.

◆Soil compaction can predict soil bearing capacity, tillage properties, and resistance to root expansion. The degree of soil compaction affects crop root penetration and growth, serving as a crucial indicator of soil physical properties for evaluating tillage suitability.

Introduction

This device is a soil moisture monitoring system comprising a handheld data logger and a soil compaction sensor. It stands out in its field with advantages such as simple operation, portability, and rapid, reliable detection.

Soil compaction, also known as soil hardness, soil firmness, or soil Infiltration resistance, is typically measured by the resistance encountered when driving a metal plunger or probe into the soil (expressed in Pa). Soil compaction refers to the soil's resistance to external compaction and fragmentation forces, representing one aspect of soil properties. Additionally, soil physical properties encompass texture, structure, porosity, and other factors affecting soil firmness, plasticity, permeability, drainage, water retention capacity, and root Infiltration difficulty.

Soil compaction is composed of shear strength, compressive strength, and friction resistance, serving as a composite indicator of soil strength. When a metal plunger or probe is pressed into the soil, both dynamic and static load methods are used. The measured values differ between methods but are correlated. The shape of the plunger—such as conical, flat-headed, spherical, or wedge-shaped—also affects 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 predicts soil bearing capacity, tillability, and resistance to root expansion. Its degree affects crop root Infiltration and growth, serving as a crucial soil physical property indicator for evaluating tillability. Compacted soil impedes water infiltration, reduces fertilizer utilization, hinders root development, and ultimately leads to reduced crop yields.
