Soil Conditions: Mildly Wet (soil is wetter than normal, local vegetation is healthy)

The fields referenced in today’s report have experienced some hail damage, though the plants will fortunately grow out of it as the damage was not too severe and there is enough healthy tissue to enable the plant to overcome the damage.…
