Friend and I are growing a crop outside. 2 weeks away from putting the seedlings into the ground now and we found an underground spring out near our grow site. We took a shovel to the soil and about 12 inches down water started gurgling back up and it's really moist. The soil is straight black and crawling with earth worms. I noticed ferns and some type of thorny/wild berry plants growing all over the place in this soil and there are places where the water is visibly pooling up to the top of the soil. Everywhere around the puddles is just really moist and super loamy black soil with worms. Do you think it would be wise for us to dig this soil up and use it for our plants to grow in? I don't have a soil ph test kit or anything but just going off of what I see it would seem to me like good soil to grow in. Thanks.
