Does OrganiCalc recommend a certain amendment, but you have a different amendment you want to use? Here is a handy converter to help you use what you have.
Note: OrganiCalc and all of us at Grow Abundant Gardens do not want to create nutrient excesses in garden soil. So we do not recommend any amendments that will cause an excess. For example, if your soil already has enough magnesium, we won’t recommend an amendment with magnesium in it. The same is true for this calculator. It won’t recommend an amendment with nutrients that were not in the original amendment.
