Crushed Granite Organic Fertilizer
Crushed Granite (CG), as a organic fertilizer, is a
slow-releasing source of potassium and trace minerals. It can last up
to 10 years in your organic garden soil. It contains 67% silica (silica
plays an important role in overall soil fertility) and 19 trace
minerals. It’s a great soil conditioner for clay based soils
CG is a mineral and very similar to what the mineral content
of your soil is made of - ground up rock. If your native soil is mainly
granite, adding more will do little to improve that soil.
Its important when adding ominerals such as CG to your soil
that add sufficient amounts of organic matter (compost) so the bacteria
can convert these minerals to needed nutrients.
CG is a very nice looking material in your garden paths and
comes in many sizes. Some varieties of CG are screened for different
sizes, and some contain particle sizes down to dust.
