How to measure soil compaction?

Importance of Soil Compaction Measurement.
Plants absorb nutrients and water from the soil through their roots, so the strong growth of the root system is very important for the good growth of the above-ground parts of the plant. The root system is buried in the soil, and its growth is naturally inseparable from the soil environment. As an important indicator of the physical properties of soil, compactness can indicate the compactness of the particle arrangement in the soil. This parameter can be used to predict the soil's carrying capacity, tillage capacity and root elongation capacity, providing a basis for scientific soil improvement. Aoda Instrument's soil compaction tester is an important tool for technicians to understand and master soil characteristics. It automatically collects data through sensors and has a GPS positioning function. The instrument management cloud platform can automatically produce various data curves and import them into the computer. Soil compactness distribution map can be drawn, which can be used in soil science research and agricultural production.

Functional features of soil compaction tester.
1. Wireless communication function: Contains mobile APP, supports Android and Apple systems, can automatically upload measurement data. The device communicates with the server through 5G/4G network, sends it to the server in real time, and can view the data on the web page, no matter where you are, as long as you can Download data can be viewed by surfing the Internet;

2. The soil compactness analyzer adopts a low-power design and adds system monitoring and protection measures to avoid system crashes;

3. Chinese LCD display, which can display the current date and time, each sensor measurement data, storage capacity, number of stored data, and other information.

4. The host has large data storage capacity: the internal Flash of the device can store nearly 30,000 pieces of data, and the standard 4G memory card can store it, or it can be stored simultaneously with the data in the Flash.

5. Built-in lithium battery power supply: 7.4V2.8Ah lithium battery, with charging protection and low voltage prompt functions. The external power supply is 8.4V (above 1000mA) DC power supply.

6. Collection settings: When used without supervision, scheduled collection can be set or manual collection can be set.

7. Voice settings: You can set the voice broadcast function on/off/over-limit on as needed.

8. Voice alarm function: After the host voice is set to over limit, the over limit information can be broadcast by voice.

9. The host can connect to different types of sensors through the hub without affecting the accuracy of each other.

10. The soil compactness analyzer has its own GPS positioning function, which can automatically display the geographical coordinates of the collection point during data collection.

11. The sensor type and quantity can be expanded to 32 (the expansion line is IP67, integrated structure).


Management cloud platform functions.
1. The built-in instrument cloud management platform includes a C/S architecture, which can aggregate and analyze the data of all portable devices and online devices without losing data backup. The viewing operation methods include web pages and mobile phones (available for Android/Apple systems).

2. Display the data collected by each sensor, detection time, and GPS coordinate information of the collection location.

3. Data can be uploaded to the management cloud platform through 5G/4G network or USB data cable import. Data within the platform can be downloaded, analyzed, and printed;

4. The platform supports equipment data storage, provides report forms such as curves and tables, provides sufficient capacity for long-term storage, and data can be exported and imported.

5. The platform data can be printed as reports, has report export function, and the supporting software can be upgraded online.
