What are the current agricultural soil testing equipment

1, soil pH tester

Soil pH meter mainly detects soil pH, moisture and humidity. The probe can be inserted into the soil under test until the distance between the soil and the fuselage is no more than 2.5 cm. Wait up to 10 seconds until the pointer stabilizes to read the data. The operation is relatively simple.

2, soil salt analyzer

Soil salinity analyzers can also be called soil salometers. We know that the greater the salt content in water, the stronger the water's electrical conductivity. Therefore, according to the size of conductivity, the degree of salinity in water can be calculated. Directly embedded, read data, easy to operate.

3, soil moisture tester

Soil Moisture Detector mainly detects moisture and humidity, and based on dielectric theory and frequency domain measurement methods to achieve rapid measurement of soil moisture, because the change of soil dielectric constant usually depends on the soil moisture content, and the relationship between output voltage and moisture The soil moisture content can be calculated. Measurement methods: plug-in, buried, profile, etc., easy to operate.

4, soil nutrient speed tester

The main items of soil nutrient tester include ammonium nitrogen, nitrate nitrogen, available phosphorus, available potassium, organic matter, total nitrogen, pH value, moisture, and alkali-hydrolyzed nitrogen; trace elements: calcium, magnesium, sulfur , iron, manganese, boron, zinc, copper, chlorine, silicon and so on. Heavy metals: heavy metals such as lead, chromium, cadmium, arsenic, and mercury.

5, soil testing formula fertilizer application

The soil testing and fertilizer application instrument mainly detects the soil moisture, pH, salt content, ammonium nitrogen, available phosphorus, available potassium, organic matter, alkaline nitrogen, nitrate nitrogen, available calcium, available magnesium, available sulfur, available iron, effective Manganese, available boron, available zinc, available copper, available chlorine, available silicon, total nitrogen, total phosphorus, total potassium, etc. Built-in expert fertilization system. Easy to operate, no calibration, direct testing, fast speed.
