Why are the NPK numbers lower in organic fertilizers as compared to synthetic fertilizers?
In nature, you will not find high concentration of nutrients. In chemical fertilizers, higher concentrations are achieved by using synthetic means. If you ‘organic-minded’ than you would understand that nature works at its own pace and does not believe in forcing growth by unappropriate and indiscriminate feeding of plants and crops . Organic fertilizers are made from such ingredients occuring in nature and hence have lower concentrations as compared to synthetic fertilizers.
