Product Description:

Silicon is a very important plant nutrient element, and the available silicon content in soil affects the photosynthesis, respiration and resistance of plants to adversity. Silicomolybdic acid is formed by silicomolybdic acid and ammonium molybdate under weak acid condition, which can be reduced to silicomolybdic blue by reducing agent and has a characteristic absorption peak at 700nm. The effective silicon content of soil can be calculated by detecting the change of wavelength at 700nm.

Note: Before the experiment, it is recommended to select 2-3 samples with large expected differences for pre-experiment. If the absorption value of the sample is not within the measurement range, it is recommended to dilute or increase

Sample size for detection.
