Gaia Green Rock Phosphate is a naturally occurring mineral which has been
ground to a fine dust. This dust is then granulated with natural binders,
either lignosulfonate or molasses. The granulating process produces a consistently
sized particle which is easy to apply and is completely free of dust.
After application, Gaia Green Rock Phosphate will dissolve in water, returning
the rock phosphate to a powder form. In addition to its binding qualities,
Lignosulfonate naturally chelates the trace minerals in the rock phosphate
making them available. Plants with high cation exchange root systems
(legumes and grains) are found to be effective in obtaining phosphorous
from soil and rock phosphate. Gaia Green Rock Phosphate contains
27% total P205 with 3% available. The remaining amount of P205 is
released over a period of about four (4) years.
Good slow release source of phosphous. Excellent in perennial flower beds.
