You might say that it takes true \u201cgrit\u201d to be a farmer\u2014or a backyard gardener, for that matter. It takes resolve and strength of character to deal with all the things that Mother Nature throws at you.<\/p>\n

The word \u201cgrit\u201d can also mean small, loose particles of stone or sand. When it comes to rock dust, sometimes also called rock flour, there is more to grit size than meets the eye. In fact, it can be difficult to identify different grit sizes with just the naked eye. That\u2019s where a sieve analysis comes in handy.<\/p>\n

Independent sieve analyses show that Cascade Minerals Remineralizing Soil Booster<\/strong>, made entirely of all-natural volcanic basalt, contains multiple grit sizes. This distinguishes it from competing products which are made almost entirely of small particles, or \u201cfloury fines.\u201d Unlike other rock dust products, Cascade Minerals Remineralizing Soil Booster contains a balanced blend of floury fines and<\/em> coarse grit. The smaller particles release essential minerals immediately, while the larger pieces erode more slowly thereby releasing more minerals over time.<\/p>\n

Importantly, the range of particle sizes in Cascade Minerals Remineralizing Soil Booster also helps improve handling and application.\u00a0 When loaded into a hopper, our product doesn\u2019t bridge or \u2018rathole,\u2019 both of which can be costly flow problems.<\/p>\n

To measure grit size, rock dust is passed through a series of mesh screens that measure the percent of material that is allowed to pass through. As evident in the following analysis, Cascade Minerals Remineralizing Soil Booster has things well covered:<\/p>\n

\n
• 28% is made up of particles of grit size #16 \u2013 as these pieces break down into smaller sizes they aerate the soil and continue to release essential minerals to the soil over time (typically over a period of one to two years).<\/li>\n
• 45% is between grit size #20 and grit size #50 \u2013 these particles are about the size of sand and are especially effective at treating weathered clay soils and breaking up super-fine silt. They erode slowly, on a timescale of about 6 months to a year.<\/li>\n
• 11% is smaller than grit size #50 but larger than grit size #200 \u2013 these particles are smaller than sand but larger than clay. With a slow release timescale of 2-6 months, they help improve the texture of weathered and tired soils.<\/li>\n
• The remaining 16% passes through #150 and #200 mesh screens and can be considered super-fine. They dissolve readily in water and are taken up by the plants within the first few days and weeks of application, i.e., they are considered \u201cinstant release.\u201d<\/li>\n<\/ul>\n

  Many of the rock-based mineral amendments on nursery shelves today can be considered part of the \u201cinstant release\u201d category, i.e., they are made almost entirely of super-fine powders that have the consistency of flour. The downside is that this type of \u201crock flour\u201d can turn to clay very quickly.\u00a0 Moreover, there is an upper limit on how much super-fine powder can be added to the soil without choking plants. This is why many competing products recommend low rates of application several times a year.<\/p>\n

  In comparison, Cascade Minerals Remineralizing Soil Booster contains larger grit sizes that take advantage of nature\u2019s own slow methods of releasing rock minerals to the soil. A single application can last a year or more, resulting in less work and a greater return on investment. Importantly, unlike small particles that are only visible on a microscope, the larger rock materials in Cascade Minerals Remineralizing Booster provide shelter for nematodes, earthworms and other biological critters that are essential to soil health and productivity.<\/p>\n","protected":false},"excerpt":{"rendered":"
