In the study of ecology, the Winogradsky column is used for the effective cultivation of microbial growth in the water and soil of lake or stream to study the microorganisms ability to survive and produce different inorganic compounds at different environmental conditions.
- The columns differs by the layers and composition such as carbon, sulphur and carbon + sulphur, exposed to light and non exposed to light so on.
- All the columns are same in the way of subjecting under changes everyday.
- The differences in the column can be seen by the changes in the color as the microbes produces their metabolic component (inorganic compound) which alters the pH of the environment gives different colors based the substrates present in the particular area. Thus based on the metabolic strategies, microbial population produced geochemical gradients inside the column.

Barrier methods, which prevent pregnancy by keeping the sperm from reaching the egg.
