how can you identify whether the soil is fertile

When the soil is neither too wet nor too dry, dig a hole 6 to 10 inches deep. Separate an intact section about the size of a soup can and break it apart with your fingers. Determine whether the soil is cloddy, powdery, or granular. Ideally, your soil should be made up of different sized crumbs that will hold their shape under slight pressure. Crumbs, or aggregates, as soil scientists call them, that break apart only with difficulty mean your soil is too hard.
Why It's Important
"Soil rich in organic matter tends to form relatively round aggregates, which leads to porosity," says Tom Thompson, a professor of soil science, also at the University of Arizona. Open, porous soils allow the free movement of water and oxygen, he explains, so plants can develop strong, healthy roots.
