Sea 90 great way to mineralize soils
5 out of 5 stars
I bough a 25 lb bag from farmers friend. I have used t(is product before, I know it has potential to help produce nutrient dense healthy crops.
I applied mine late April, I won’t know for sure how much it helped until later in the season, as my climate is short growing season.
My only concern was when the bag arrived it was wet and a brown color, most likely from being shipped in the rain, or was it bagged wet?
Don’t know if this will cause any problems in storage or after it is applied.
I mention this because last time I bought some it was white in color.
