The Soil Biology Primer For farmers, ranchers, ag professionals, resource specialists, conservationists, soil scientists, students and educators. The Soil Biology Primer is an introduction to the living component of soil and how it contributes to agricultural productivity, and air and water quality. The Primer includes units describing the soil food web and its relationship to soil health, and units about bacteria, fungi, protozoa, nematodes, arthropods, and earthworms. The Primer was originally produced by the NRCS Soil Quality Institute.
Discounts are available for orders of ten or more.
The on-line version below includes all the text of the original but not all the images of soil organisms. The full story of the soil food web is more easily understood with the help of the illustrations in the printed version. The Soil Quality Institute of the Natural Resources Conservation Service, with assistance from the Conservation Technology Information Center, provided leadership for this project. The Natural Resources Conservation Service and the Soil and Water Conservation Society thank many individuals, including the following, for their contributions. A.M. Lewandowski, eds.
