The soil fertilizer nutrient detector for the entire project can detect soil and fertilizers, organic fertilizers (including foliar fertilizers, water-soluble fertilizers, spray fertilizers, etc.), available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, acidity and alkalinity, calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, etc. in plants. The content of various trace elements and heavy metals such as lead, chromium, cadmium, mercury, arsenic, etc.

Adopting high brightness LED light source and dual dial filter processing technology to ensure stable wavelength of the light source, silicon semiconductor is used as the signal receiving system with a lifespan of up to 100000 hours. The light source is stable, with good reproducibility and high accuracy. The colorimetric groove adopts a single channel design, without mechanical displacement or wear. The optical path testing positioning is precise, ensuring the accuracy of the measurement results. It is equipped with an expert fertilization system data, which can scientifically calculate the recommended fertilization amount for more than 100 national agricultural, fruit tree, and economic crop target yields, ensuring that the detection results meet the national standard requirements.
