About the soil water stress coefficients

Hello Tom and others,

Aquacrop has 4 different water stress thresholds (p_hi and p_lo) which target different variables (or processes) - canopy expansion, canopy senescence, stomatal closure and pollination. However, even when I schedule irrigation based on a soil moisture threshold which is “more highly depleted” (lesser soil moisture) than the soil moisture threshold when canopy expansion stress should occur, I don’t see any differences in CC and potential CC. What am I doing wrong?

Thanks in advance,
Soham

Hi @sadla

If the soil water content drops below the p_hi threshold, water stress should occur. I would have to see the exact code and params you used. Or can you repeat the bug using built in weather and crops?
