Seeds that do not grow

Question

We planted corn, squash and cucumbers and they did not come up. The soil was not disturbed, but when we dug up some seeds to see if they had germinated, the corn seeds were gone and squash seeds were empty husks. This was newly purchased seed, dated for this year’s planting. Beets, lettuce and carrots are doing well, and only about 1/3 of the peas came up. What’s happening?

Answer 1

Even though the soil is not disturbed, I still suspect that some small animal is taking it, possibly from below. Possibilities include voles or chipmunks. This article will help:
