Description
Overview
GAOTek plant nutrient tester instantly measures the relative chlorophyll content (in SPAD) or greenness of plants, nitrogen content, foliar moisture and foliar temperature to understand the true nitro requirements of plants and to know if the soil is deficient in nitro or if too much nitrogen has been applied. The instrument can be used to increase the utilization of nitrogen fertilizer and to protect the environment. It can be widely used in agriculture and forestry related research units and universities for research on plant physiological indicators and agricultural production guidance.Â
