Superior AG Liming Oyster Shells

Products from Nature

Pacific Pearl Oyster Shell – Nature’s Best Calcium:

Lind Marine has been mining historic oyster shell deposits in South San Francisco Bay for use as ag lime soil amendments since 1906. The calcium carbonate in the oyster shells helps to neutralize acidic soils. After the oyster shell deposits are harvested, the shells are barged to and processed at our Collinsville plant, and then shipped to agricultural customers throughout the Western United States, Canada and the Pacific Rim. Our customers include: orchards, vineyards, tree farms, golf courses and berry farms, among others.

Ag Lime – Oyster Shell Flour Soil Amendment

Flour / AG Lime

Flour / Ag Lime is finely ground oyster shell that has a smooth velvety feel. Its texture and high quality make it highly desirable in numerous commercial and agricultural applications, and well as a feed additive. Available in 50 lb. bags, bulk bags, and in bulk.

Five Outstanding Reasons Why Oyster Shell Calcium Gives Superior AG Liming Results
  1. Oyster shell is produced by a living organism Calcium formed in this non-crystalline state is more easily dissolved and utilized by the soil and plants
  2. Particle shape and texture
    Oyster shell calcium is formed in thin, delicate layers that readily break down into flake-shaped particles
    The porosity and irregular shape of the shells exposes an immense surface area that reacts with acids in the soil
    The oyster shell particles anchor themselves in the soil and resist leaching
  3. High calcium carbonate analysis
    Guaranteed minimum calcium carbonate 96%
    Guaranteed minimum calcium 36% (typically 38% – 39%)
    Moisture content less than 1% (average .2%)
  4. Sized specifically to cause a timed release of calcium
    1/3 fine particles to produce a rapid pH change (-325 – 200 mesh)
    1/3 medium particles to replace calcium as it is leached out or taken up by the plant or turf during the growing season (100 to 60 mesh)
    1/3 coarse particles to provide a long-term source of calcium (40 to 20 mesh)
    Approximately 55 lbs. per Cu. Ft.
  5. Oyster shell supplies additional plant growth requirements
    Ten other important nutrients and micronutrients are found in oyster shells
