If you want your vegetables to not only taste better but be healthier then adding rock dusts or trace minerals is important. Plants need more than just NPK and much of that is provided by rock dusts like basalt. What makes basalt special is that it contains many of these trace elements at good levels without high heavy metals or other elements that we don't want in our garden like arsenic and lead. See the link at the bottom for a true comparison, but basalt is something that I consider a must-have ingredient in my soil mixes and garden. It also happens to be paramagnetic and work really well as a de-icer in the winter. Much better than throwing down a bunch of salt that increases the salinity in my yard with the runoff.

Agricultural Lime (Calcium Carbonate ) is a soil conditioner made from crushed limestone. It is an excellent calcium source. The benefits of agricultural lime include: Improving the physical, chemical and biological properties of the soil Promoting better nitrogen fixation by legumes Increasing the availability of nutrients to plants Reducing toxicities in the soil...
Organic Alfalfa Meal – NPK 2-1-2 All rose growers have heard "you have to use alfalfa on your roses." Well there's a reason behind that claim, and it has to do with a few key benefits: 1. Alfalfa meal naturally contains triacontanol, an amazing growth hormone that increases yield and...
Azomite AZOMITE® is a highly mineralized complex silica ore (Hydrated Sodium Calcium Aluminosilicate or HSCAS), mined in Utah from an ancient deposit left by an volcanic eruption that filled a small nearby seabed an estimated 30 million years ago. AZOMITE® is used as a naturally rich soil re-mineralizer for plants,...
