Soil Solidity Tester

Instrument Introduction

This device is a soil moisture monitoring system composed of a handheld data collector and a compaction sensor. At the same time, it has the advantages of easy operation, convenient portability, and fast and reliable detection, making it unique in the field. The handheld data collector can be configured with GPS, GPRS data upload and other functions according to user needs at the factory. The data in the device can also be connected to a computer through a USB data cable, and historical data can be exported to the computer for data analysis.

Soil compaction, also known as soil hardness or soil solidity or soil penetration resistance. It is generally expressed as the resistance (in Pa) when a metal plunger or probe is pressed into the soil. Soil compaction refers to the ability of soil to resist external forces, including compaction and fragmentation, and is one aspect of soil properties. In addition, soil physical properties include soil texture, structure, porosity, etc., which involve soil solidity, plasticity, permeability, drainage, water storage capacity, and the difficulty of root penetration.

Soil compaction is composed of soil resistance to shear, compression, and friction forces. It is a composite indicator of soil strength. When a metal plunger or probe is pressed into soil, there are two methods: dynamic load and static load. The measured values of different methods are different, but they are related. The shape of the plunger includes cones, flat heads, spheres, wedges, etc., which also have an impact on the measured values. The measured values of the same method are mainly determined by soil texture, bulk density, and moisture content. The impact of moisture content is the greatest among them. Soil compaction can predict soil carrying capacity, tillage performance, and resistance to root extension. The size of soil compaction can affect the perforation and growth of crop roots, and is an important soil physical property indicator used to evaluate soil tillage. Tight soil can prevent water infiltration, reduce fertilizer utilization, affect plant root growth, and lead to crop yield reduction.
