Soil Remineralization
Mark S. Kuhar

Back in the early 1990s, there was an industry effort brewing to divert production fines from aggregates plants to agricultural operations for use as a soil additive. In 1994, the National Aggregates Association held a conference on Remineralization and Sustainable Agriculture, and, in 1995, an important soil remineralization article written by Robert J. Able of Dan Gernatt Gravel Products, Collins, NY, was published in the pages of Pit & Quarry.

Unfortunately, that effort lost steam. But today, more than ever before,
In other words, how do we move from aggregates to agriculture?
soil remineralization is needed. After decades of heavy agriculture use, today’s soil has lost fertility, and the heavy use of chemicals and pesticides have taken a toxic toll. While there is ample research that production fines, or “rock dust” to the outside world , have a positive impact on soil quality, the strategic question has always been:
How do we get stone producers together with farmers and nursery operations? In other words, how do we move from “aggregates to agriculture?”

Pit & Quarry hopes to play a key role in a renewed effort to make soil remineralization a reality. A National Task Force for Soil Remineralization is now being formed. I would like to ask any aggregates producer with a vested interest in soil remineralization to get involved, either by direct participation in the task force, or by adding the name of their operation to a database of operations that are interested in partnering with an agricultural operation.

You can add your name to either list by sending me an e-mail at Your participation is greatly needed . This is a chance for aggregates producers to not only make an important contribution to the global food chain, but also to create a significant opportunity for positive press. And that doesn’t come along every day.
