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.
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.
