It may seem counter intuitive to add sandy fertilizer to plants that are lacking minerals. But this fertilizer takes advantage of organic acids in the ground to release minerals that are otherwise insoluble. As dead leaves and yard trimmings decompose, they release humic acids. More acids, such as malic acid, citric acid, and acetic acid are produced during the lifecycle of soil bacteria. All of these acids accumulate in soil unless there are soil components that neutralize them. Greensand fertilizer...

This is a recommended rate, Universities and growers actually use the material straight, nothing else, as a soil mix for growing plants, and they do very well. It really cannot be over applied unless you smother the plant. Many cultures actually use lava lock and sand as a plant mulch. The entire Island of Hawaii is growing out of this stuff to varying degrees. Ours is sourced from extinct volcanoes in New Mexico and Colorado (thankfully, can you imagine getting this from an active volcano?)

The Expanded Shale also helps the roots in another way. The shale is treated using a hot kiln, causing it to expand like popcorn. Heat causes air pockets inside the shale to grow, and large air pockets are great for holding moisture. Air cavities increase the water carrying capacity of soil, and they allow roots to grow quickly because the dirt is lighter and more porous. Earthkind Roses are especially fond of expanded shale.

Mycorrhizal fungi spores are the special ingredient in this line of all-natural growth stimulants. These beneficial fungi protect plant roots from many fungal diseases, improve soil structure and assist with nutrient uptake. The result is stronger, healthier plants with increased yields. Place the tablets directly in soil to release their spores.
