DETERMINATION OF AIR REFRACTION INFLUENCE ON TRIGONOMETRIC HEIGHT DIFFERENCES
Efficiency of trigonometric levelling method for height differences determination is better than those determined by geometric levelling but its accuracy is significantly lower. Development of accuracy of geodetic instruments increases possibilities for improvement accuracy of trigonometric levelling.However, air refraction appears as ultimate limi...

HUMIC ACIDS OPTICAL PROPERTIES OF RENDZINA SOILS IN DIVERSE ENVIRONMENTAL CONDITIONS OF SERBIA
This study examined the impact of climate, altitude and landforms on humic acids (HA) optical properties (E4/E6, ∆logK, RF indexes) in Serbian Rendzina soils. HA humification degree of calcareous and decarbonated Rendzinas under natural vegetation (forest and grassland, separately) decreased with altitude increasing. This particular rule was not ma...
