Selyaninov's Hydrothermal Coefficient
Selyaninov's Hydrothermal Coefficient (HTC) is an agrometeorological index used to assess the degree of moisture supply by comparing precipitation amounts with active temperature sums.

The HTC is widely utilized to determine the moisture conditions for crop growth and development. By analyzing these values, agronomists can estimate the level of drought stress or water excess, which is essential for effective irrigation management and crop yield forecasting.
Practically, the coefficient helps in making decisions regarding soil moisture conservation. A common mistake is relying solely on this index without considering soil-specific properties or previous moisture reserves. It is best applied alongside field monitoring to ensure precise agricultural interventions during critical crop growth stages.
