Informative value of infrared survey data for detecting properties of arable soils

Possibility of detecting soil fertility parameters based on the use thermal survey data was studied test area Yasnogorsky District, Tula region, Russia. The has gray forest slightly eroded arable soils located in flat part slope. During field works, an open surface photographed using a FLIR VUE 512 imager (range 7.5-13.5 mkm), samples were also taken from layer 0-5 cm and moisture measured 15-20 cm. For almost all (pH, humus content, potassium exchange cations - Mg++, K+, Na+), statistically significant correlation established (r =0.4-0.7) between them range spectrum. moderate correlations, polynomial regression equations compiled. Among parameters, pH salt extract, content oxide had coefficient determination (R2 0.60) with spectrum R2= 0.61, R2 =0.60 = 0.63, respectively. obtained results have shown that imaging can be used to map some for region. Nevertheless, it turned out impossible reliably detect main basis data. However, as auxiliary when shooting visible nearIR ranges, which helps improve accuracy contactless monitoring.
