Uses: Rational application of nitrogen fertilizer is an important means of increasing crop yields, but determining how plants can use nitrogen fertilizer most efficiently

Methods to determine the best time to apply fertilizer are expensive and time-consuming. The CM 1000 NDVI measuring instrument is normalized by measurement

Using the Vegetation Difference Index (NDVI) to obtain nitrogen utilization and nitrogen requirement data can help you quickly, timely and efficiently.To understand the required nitrogen fertilizer content of crops and accurately grasp the fertilization time.
