Abstract: Agricultural producers to determine irrigation scheduling practices for crop‘s water requirement better when the soil water content of their fields is known. Selyaninov Hydrothermal Coefficient (HTC) coefficient is used for identifying droughts during the active vegetation period, based on the water balance equation. For farmers to make measurements of soil moisture is simply with humidity sensors, for example Watermark type. Soil humidity values established using Watermark type humidity sensors, value interpretations are based on manufacture indications, however they have not been adapted to Lithuanian conditions. Soil moisture was measured with Watermark soil moisture sensors placed at 20 and 50 cm depths. After analysing the values taken throughout the whole period and summarizing the results it has been identified that plant growth condition period evaluation according to HTC and factual soil humidity reserves (W) differs by 20%. HTC meaning dependencies during vegetation period using Watermark measured humidity, strong or averagely strong interrelation is determinate, in most cases – statistically significant. When evaluating soil humidity reserves based on soil texture, it is recommended to keep the critical Watermark level in light texture soil (sands) at 80 cbar, and in all other types of soil - at 150 cbar. The results clearly indicate that soil composition could be factors limiting the success of identifying droughts in agriculture carried by Watermark type humidity sensors
