Soil (fertilizer) nutrient rapid analyzer, abbreviated as soil fertilizer analyzer, can quickly detect ammonium nitrogen, available phosphorus, available potassium, organic matter in soil, plants, chemical fertilizers, biological fertilizers and other samples. It has a large LCD screen display, high detection accuracy, short detection time, and can be equipped with built-in expert software, providing strong scientific basis for quickly specifying various crop fertilization plans.

Performance characteristics:

1.3.5-inch LCD screen, fully Chinese interface

2. There are two power supply methods: AC and DC. When used outdoors, rechargeable batteries can be used for power supply

3. The optical system adopts a design of LED cold light source, high-precision narrowband filter, and silicon semiconductor, with a lifespan of up to 100000 hours

4. Select the detection item directly from the menu, and the light source will automatically switch

5. Technical indicators are superior to the requirements of the national standard JJG179-90

The simultaneous extraction of nitrogen, phosphorus, and potassium from soil can be completed in 6.3 minutes, and the detection of nitrogen, phosphorus, and potassium content in a soil sample only takes 30 minutes (including pre-treatment time)

7. Can be equipped with external printers, wireless communication modules, GPS positioning modules, etc

8. Optional addition of expert fertilization system software

A. More than 70 types of crop expert fertilization suggestions can be stored in real-time, on-site, added, supplemented, and updated with crop types, abundance and deficiency indicators, fertilization indicators, etc., applicable to crops without restrictions

B. Based on crop variety, soil content, fertilizer content, and fertilizer price, the best fertilization plan can be automatically recommended, and more than 1000 can be saved without restrictions

Test project:

1. Soil nutrients: organic matter, nitrogen, phosphorus, potassium

2. Fertilizer nutrients: nitrogen, phosphorus, and potassium in elemental fertilizers; Nitrogen, phosphorus, and potassium in compound (mixed) Hefei and urea; Ammonium nitrogen, available phosphorus, available potassium, and organic matter in organic fertilizers.
