While our planting was not, by any means, a scientific test worthy of peer reviewed journals it does speak to the fertility and utility of the Zinks soil.- We received a load of pedestrian top soil from our landscapers supplier. This was spread on one section of our property and native grasses and wildflowers were planted.- We received a load of soil from the Zinkls two days later and executed similarly on another section of our property.Two weeks later the Zinks soil is rich with small grasses and wildflowers. The other soil is barren.It doesnt get any better.

My favorite!
