Soil compaction tester

This entry is provided by TOP Cloud Farming Equipment Network

The soil compactness tester is also called the soil solidity and hardness tester. This instrument is developed by TOP Instruments. The main models are TJSD-750 and TJSD-750-II. There is also a GPS soil compaction measuring instrument of the same type, which has a built-in GPS positioning and depth measurement system, which can simultaneously display the soil compaction, measuring depth and geographic location, and automatically connect to a computer to generate soil compaction at each measurement point. Reality curve. The instrument can currently be used to measure soil compaction in the field. Tight soil can prevent the infiltration of water, reduce the utilization of chemical fertilizers, affect the growth of plant roots, and reduce crop yield. Therefore, it is especially important to know the compactness of the soil. This instrument can better guide agricultural production and highway construction.

    Instructions

      Soil compaction meter use:

      Soil compactness is also called soil hardness or soil firmness or soil penetration resistance. Resistance is generally expressed when a metal plunger or probe is pressed into the soil (the unit is Pa). Soil compactness refers to the ability of the soil to resist compaction and fragmentation by external forces, and is one of the aspects of soil properties. In addition, soil physical properties include soil texture, structure, porosity, etc., which are related to soil solidity, plasticity, permeability, drainage, water storage capacity, and difficulty of root penetration.

      Soil compactness consists of soil shear, compression, and friction. It is a synthetic indicator of soil strength. There are two methods of dynamic load and static load when the metal plunger or probe is pressed into the soil. Different methods have different measured values, but they are related. The shape of the plunger includes a cone, a flat head, a ball, and a wedge. These also affect the measured value. The measured value of the same method mainly depends on the soil texture, capacity and water content. Among them, the influence of water content is the largest. Soil compaction predicts soil load, arableness, and resistance to root extension. The degree of soil compactness can affect the perforation and growth of crop roots, and it is an important indicator of soil physical properties, which is used to evaluate soil fertility. Tight soil can prevent the infiltration of water, reduce the utilization of chemical fertilizers, affect the growth of plant roots, and reduce crop yield.
