After these amendments are
applied to the soil, their numbers and
fermentative activities can increase dramatically and overwhelm the indigenous
soil microflora for an indefinite period.
While these microorganisms remain predominant, the soil can be classified as a
zymogenic soil which is generally characterized by a) pleasant, fermentative
odors especially after tillage, b) favorable
soil physica1 properties (e.g., increased
aggregate stability, permeability, aeration
and decreased resistance to tillage), c)
large amounts of inorganic nutrients,
amino acids, carbohydrates, vitamins and
other bioactive substances which can directly or indirectly enhance the growth,
yield and quality of crops, d) low occupancy of Fusarium fungi which is usu-
ally less than 5 percent, and e) low production of greenhouse gases (e.g., methane, ammonia, and carbon dioxide) from
croplands, even where flooded rice is
grown.
