All photographs on this website that show Vitazyme treated crops vs. a control were taken of samples extracted from the field with the following criteria:

• Samples were taken as close together as possible, often from adjacent rows.

• Care was taken to select samples from areas of average growth and vigor for their respective areas, and to avoid areas such as wet spots or excessively dry areas or other anomalies.

• Often the researcher did not know which area was being sampled, and took 'blind' samples from the field.

• Samples from both treated and control were taken from similar population densities, and from the same distance in the row.

• The same number of plants are in the Vitazyme treated as in the control in each photograph. When an unequal number of plants are taken from the field the largest plants are selected for the photograph.
