It happens in our technological society that we sometimes increase the complexity of something (such as fertilizing a garden) well past the point where demising returns take over. That is the more time, effort and physical resources we apply, the increased productivity fails to compensate for the additional inputs. In my opinion remineralization looks something like a complex and time-consuming way to implement the law of diminishing returns.
I have some practical concerns:
I'm not sure I'll know if the veggies are truly nutrient dense or even more so. How can I measure this? Ultimately, if I can't measure a difference I can't say it has been effective.
Overall, I see the approach as adding greatly to my preparation time. Nevertheless, I'm committed to doing this as best I can because I have aimed at improving soil fertility in all my gardens for several years. This may be a way to do that.
