Soil Biology

Length: 24 minutes

This program is loaded with information on the many organisms which make up the soils environment. From easily visible earthworms to microscopic bacteria, discover valuable information on the roles and interactions of the soil's flora and fauna. See how soil biology relates to soil horizons, porosity, water holding capacity and other physical properties of soil.

While soil fertility is often measured by a soil's chemical, mineral and organic matter content, new research is presented on how the many species of mesofauna can be extracted from the soil and then used as indicators of soil fertility. Examine soil pests as well as beneficial life forms found in the soil. Also see human attitudes towards soil organisms and learn how opinions can develop which are not always based on science. Clear narration, effective use of graphics and fascinating microphotography bring into focus the many life forms in the soil of our farms and landscapes.
