Soil is alive. Many visible and microscopic creatures make homes in upper soil layers. Soil sustains life for plants. Nitrogen from the air as well as phosphorous and potassium from rocks enter soil to fertilize the roots of healthy grasslands, forests and crops. Soil scientists recognize twelve orders or types of soil. ISBN 978-09726255-3-1 $18.95 |
