'Soil' in the Bible

Other seed fell on rocky ground where it did not have much soil. It sprang up at once because the soil was not deep.

But other seed fell on good soil and produced grain, sprouting and growing; some yielded thirty times as much, some sixty, and some a hundred times."

But these are the ones sown on good soil: They hear the word and receive it and bear fruit, one thirty times as much, one sixty, and one a hundred."

By itself the soil produces a crop, first the stalk, then the head, then the full grain in the head.
