Tuesday, January LETHBRIDGE HERALD-7 Research Station report: Soil is full of living bodies By DR. J. L. NEAL .Soil Microbiologist Soil is a living body that teems with microscopic plants and animals. More living, functioning organisms live in one gram of garden soil (about one quarter of a teaspoon) than there are humans on the earth. As a living body, soil can convert large quantities of plant wastes back to their elemental forms. These elemental forms serve as food for succeeding generations of plants. Soil thus forms an extremely important part of the energy and nutrient cycle on earth. However, to regard soil solely as a debris decom- poser rather than a living body will inevitably lead to problems. Soil, like any other living body, can become ill. A healthy soil will grow a good healthy crop. An ill soil will grow' only poor crops. Many factors will cause a soil to become ill. At the Lethbrjdge Research Station, we are attempting to measure the health of soil by studying the chemical changes brought about by substances called enzymes. Soil enzymes are biological catalysts that cause a chemical change or reaction to take place but are not destroyed by the reaction. These reac- tions are of major impor- tance to good soil health. The enzymes are produc- ed by soil microorganisms VANEE LIVESTOCK LTD.

However, there is one im- portant difference, they are attached to the soil particles. Because of this attachment, they are very resistant to most chemical and physical changes in the soil. These changes would normally destroy the enzymes or reduce their ability catalyze chemical reactions. We have found that certain soil enzymes can function over a wide range of temperatures from freezing to near- 100 degrees, because of this unique binding to soil par- ticles. They can tolerate high concentrations of soil salts or very acid soils. Some can function in soil that is too dry or too wet for plant growth. We have also found that plants can alter the kinds or types of enzymes present in soil about their roots. WHY FEED ANGUS? 'roven to feedlot. Wins more carcasses competitions than any other breed.
