Today, remote sensing is used for plant studies, such as determining nutrient levels, plant diseases, water deficiency or excess, weed identification, and so on. As electromagnetic waves strike the plants, they react in different ways (absorption, reflection or passage) based on the characteristics of the plants. The quantity of nutrients in a plant can be determined through measurement science in plant studies. Since the amount of nutrients in the plant can be determined, it is possible to know how much fertilizer the plant needs. On the other hand, identified the nutrients in the plant, especially rangeland plants. A spectrometer was used to measure the plant's response to electromagnetic waves in the range of 0.3 to 1.1 m. Following that, the relationship between the amount of electromagnetic waves and the amount of nutrients in these plants was determined. The results showed that in Fagonia bruguieri b1026 nm, in Peganum harmala b1040 nm, in Ziziphus spina-christi b1046 nm, in Tecurium persicum band 1030 nm, in Vitex pesedo-negundo b400 and b1038 and in Otostegia persica band They are effective in predicting the value of P. For the prediction of Zn in F. bruguieri b1026 nm band, in P.harmala b1040 nm band, in Z. spina-christi ba1045 nm band, in T. persicum pea b1030 nm band, in V. pesedo-negundo plant b1010 nm and in O. persica band They are the most effective bands. To predict Cu, it is determined using spectral band values that in F.bruguieri band is b402 nm, in P. harmala band is b410 nm, in Z. spina-christi band is b1046 nm, in T. persicum band is b1030 nm, in V.pesedo and O. persica b1038 are the most effective bands.
