This chart will be updated with each catalog publication, as new information becomes available. * The time period mentioned in these categories
represents the approximate length of time these fertilizers will last in your soil. Release period will vary, depending upon soil temperatures and
biology. **Please note: Fertilizers that do not show a dot for a particular analysis (N-P-K) may still contain smaller amounts of these. ©2003
