Questions growers ask
Is this instead of fertilizer?
No. A fertilizer feeds the crop; an amendment changes how the soil behaves. Use both.
What kind of soil is it for?
Ground that drains badly, packs hard, or has been cropped without a rest.
When and how does it go in?
Before planting, worked into the bed — easier while the ground is soft. How much depends on the state of the soil; ask us.
How soon will I see a difference?
It changes the soil rather than feeding the crop, so nothing happens overnight. It shows over seasons, as drainage and workability.
