The plant nutrient analyzer can instantly measure the relative chlorophyll content, nitrogen content, leaf temperature and leaf humidity of plants. The four parameters are measured at the same time and displayed at the same time. It provides a basis for precise fertilization and irrigation of plants, so as to avoid waste and environmental damage caused by excessive fertilization. It is helpful to increase the utilization rate of nitrogen fertilizer and provide reliable soil and crop information for precision agriculture.
