Care to expand on how moisture can “pass” through the root zone? Were you completely soaked up and above field capacity or did your crops take up the moisture in the root zone? Soil moisture doesn’t just pass form the root zone down below it. Gravity isn’t that strong to pull moisture away from soil particles so how did you loose all your root zone moisture?
Something like that happened here last summer. Fillmore and Hastings silt loams. We were extremely dry in the fall and winter of 2022, so much that we couldn't get a soil probe below 20 inches in late April 2023. The subsoil was rock hard.
But we did have a couple inches of spring moisture that slowly migrated downward through the root zone. We had no rain, but by early June of 2023 we could probe 36 inches without resistance. The deeper cores weren't at field capacity, but they weren't powder dry either.
Perhaps the very dry subsoil was pulling via capillary action? Or diffusion from wetter to dryer soil?
I don't know, I've never seen it before. But 2023 was a weird year all around. |
