Main functions |  |
The relative content of chlorophyll in the current leaves is evaluated by measuring the absorption rate of leaves in both wavelength segments. The relative chlorophyll content or "green degree" of a plant can be measured instantly. This allows you to understand the real nitro requirements of plants and help you understand the degree of lack of soil nitro or excessive nitrogen fertilizer was applied. | |
