THE POSSIBILITY OF DETERMINE PHOSPHORUS AND POTASSIUM CONCENTRATIONS IN SHEEP FESCUE (Festuca ovina L.) USING REMOTE SENSING SYSTEM
Abstract :
This study was carried out to determine phosphorus and potassium levels in sheep fescue (Festuca ovina L.) using spectral reflectance data in field and greenhouse conditions. Spectral reflectance measurements were undertaken using a portable spectroradiometer measuring the wavelength range of 325-1075 nm of the electromagnetic spectrum. The treatments consisted of different concentrations (0, 20 and 40 kg da-1) of phosphorus and potassium for each pots and plots. Spectral reflectance values were measured in both canopy level and single-leaf. According to result of the study, the changes in phosphorus and potassium levels were affected reflectance values of blue and near infrared region of spectrum which located in the range of 400-500 nm and 700-900 nm, respectively. The results have shown that spectral reflectance data (especially blue and near infrared region) could be used to estimate the phosphorus and potassium concentration in sheep fescue.
