Soil Classification: Disease-Inducing Soils

In disease-inducing soils, plant pathogenic microorgan­isms such as Fusarium fungi can comprise 5 to 20 percent of the total microflora. If fresh organic matter with a high nitrogen content is applied to such a soil, incom­pletely oxidized products can arise that are malodorous and toxic to growing plants. Such soils tend to cause frequent infesta­tions […]

Classification of Soils Based on the Functions of Microorganisms

Soils can be characterized according to their in­ indigenous microflora which perform putre­factive, fermentative, synthetic and zymo­genic reactions and processes. In most soils, these functions are going on simul­taneously with the rate and extent of each determined by the types and numbers of associated microorganisms that are ac tively involved at any one time. Pro-Soil […]
