The use and significance of soil nutrient analyzer

The soil nutrient analyzer can measure the relative content of chlorophyll or the “greenness” of the plant in real time. The chlorophyll content in the plant leaves indicates the condition of the plant itself. The leaves of the plant with good growth will contain more chlorophyll, the content of chlorophyll and the leaf. The nitrogen content is closely related, so the chlorophyll measurement can also indicate the true nitro requirement of the plant. This portable chlorophyll meter can guide the rational application of nitrogen fertilizer, improve nitrogen utilization, and protect the environment (prevent application Excessive nitrogen fertilizer causes the environment, especially the water source, to be contaminated).

Experts suggest that nitrogen has a significant impact on crop growth, yield and quality. In the absence of nitrogen, crop root production is significantly inhibited, and the formation and development of reproductive organs are also limited. The plants mature early and the fruit is small and not full. However, too much nitrogen fertilizer application will reduce the efficiency of nitrogen fertilizer utilization. Most of the excess nitrogen fertilizer will enter groundwater and surface water, causing the accumulation of nitrate nitrogen in groundwater and surface water, resulting in eutrophication of water bodies, leading to a series of environmental problems. Therefore, how to apply nitrogen fertilizer in an appropriate amount and apply nitrogen fertilizer as little as possible to reduce cost and environmental pollution without causing production reduction is an important part of fine agricultural technology research.

The soil nutrient meter is an instrument that displays the green level of a plant by measuring the value of the spad. It measures the amount of nitrogen fertilizer by measuring the SPAD value and understanding the growth of the plant. The chlorophyll meter immediately measures the relative amount of chlorophyll in plant leaves and displays the measured numbers on the LCD screen of the instrument.

Because the soil nutrient meter has fast measurement time, the LCD directly displays the chlorophyll value, the instrument is small and portable, and can be carried to the field measurement function. It is favored by more and more professionals through various plant leaf measurement samples.
