Lime

Approved for organic agriculture.  Calcium carbonate (CaCO3).

Available as pellets in 20 lb or 50 lb bags or as powder in 50 lb bags.

Microna Pro replaces "Garden Pearls" pelleted lime.

Lime is the most-used soil amendment in the Willamette Valley, applied primarily to raise pH of naturally acid soils while also supplying soil calcium.  A soil test is recommended to determine lime requirements.

Pellets are low-dust and easy to apply; powder is more economical for larger acreage.
