Hydrothermal coefficient per decade
The hydrothermal coefficient per decade is an indicator of moisture availability for crops, calculated as the ratio of total precipitation to the sum of active temperatures over ten days.

Agronomists use this metric to assess moisture levels during critical growth stages. It helps determine if crops are experiencing drought stress or excessive humidity.
The calculation is based on the total precipitation and the sum of active temperatures. A common error is relying on historical averages rather than real-time data, which leads to inaccurate field assessments.
Monitoring this coefficient every ten days is essential for making informed decisions regarding irrigation and the timing of pesticide or fertilizer applications.
