QUANTITATIVE AND QUALITATIVE ANALYSES IN NEAR INFRARED ANALYSIS OF BASIC COMPOUNDS IN SUGAR BEET LEAf

摘要

The application of the near infrared technique (NIR) on a large scale is possible thanks to the use of rapid and inexpensive computers, and facilitates both quantitative and qualitative analyses. The great advantage of NIR is rapid analyses and its non-destructive character, and possibility of measuring many different components at the same time. The NIR method was used to study changes in chemical composition in leaves of sugar-beet under the influence of various fertilizers. The results obtained show that this method is an effective tool to predict protein, nitrogen and saccharides.
