Basalt is comprised of Igneous rock that is found in many places around the world. Basalt is preferred for ERW as it contains the calcium and magnesium needed to capture CO2, as well as silica and nutrients such as potassium and iron, which are often deficient in intensively farmed soils. Iron and steel mining produce dust byproducts that could be substitutes for regular basalt. For a more immediate replenishment of nutrients, a finer grade will start to break down within a few weeks. Restore soil fertility and increase yields with 100% Volcanic Basalt Rock Dust. Silica is essential for optimal plant health and vigour, but is lacking from commercial soil mixes. This is why it's so important to always do a proper soil test, and balance your soil over time. Basalt brings in much needed micro-nutrients to deficient soils, and helps your plants uptake other nutrients. ). Spreading rock dust on farmland could suck billions of tonnes of carbon dioxide from the air every year, according to the first detailed global analysis of the technique. He said mines in Northumberland, UK, that produce basalt aggregate for construction produced 20-30% waste dust. Basalt rock dust, also known as volcanic rock dust, is an abundant source of silica and contains 56 other elements Contains: Calcium oxide 15%, iron oxide 10%, potassium oxide 1.3%, magnesium oxide 4%,silicon dioxide 37% This would remove the need to grind the rocks into fine particles, which requires energy. The finer the grade, the more dust like it is. The researchers also found that the world’s biggest polluters, China, the US and India, have the greatest potential for ERW, as they have large areas of cropland and relatively warm weather, which speeds up the chemical reactions. When the rocks are crushed to the size needed for those purposes, some of it … It was difficult to imagine at the time that any signs of life could emerge from the surrounding landscape, which was covered with dark gray ash and resembled the moon. Rock Phosphate is the organic form of phosphorus and is completely safe for rivers and groundwater. I Thought We Were Talking About Basalt Rock Dust Though? Basalt dust provides the fresh rock flour with over 60 minerals. Some farmers in south-east Asia already use it to boost depleted silica in rice fields, while trials in the Netherlands are using it to boost tree planting. 300g Beerling said ERW did not require new technology, and farmers could get behind it, adding: “If you could demonstrate to farmers in China and India, for example, that they are going to get crop yield increases and get paid $100 a tonne for removing CO2, then it becomes really attractive.”, Prof Johannes Lehmann, of Cornell University, and Angela Possinger, of Virginia Tech, both in the US, who were not involved in the study, wrote in a commentary on the work in Nature: “Any carbon sequestration involving soils is a formidable challenge because the technologies must be used on vast areas of land that are operated by hundreds of millions of farmers. Rocky. Basalt Rock Dust is an all natural soil amendment that is made from ground up volcanic rocks. Basalt will add things like iron, cobalt, zinc, and manganese to your soil. “It is quite a young science,” he said. Soils normally absorb carbon from the atmosphere, but when mixed with the dust of basalt, which is rich in calcium and magnesium and also very abundant (as a … First, many farmers already add limestone dust to soils to reduce acidification, and adding other rock dust improves fertility and crop yields, meaning application could be routine and desirable. Chock-full of minerals and nutrients, this natural soil booster is used to enhance the supply of trace elements and helps support the biological processes required for sustainable and optimal plant growth. These nutrients assist with root growth, and drive bigger yields organically The courser the grade, the more chunky the product will be. Making sure to get a test that covers all of the micro-nutrients is a good idea to make sure your soil is performing optimally for best plant growth. It is the perfect addition to living soils and composts where microbial life can maximise the gentle release of these nutrients. It is actually a byproduct of mining basalt for other purposes, such as landscaping decorative rocks, construction, and industrial uses. Basalt rock dust is packed with micronutrients like magnesium, iron, and calcium. “ERW is a straightforward, practical approach.”, Prof Jim Hansen, of Columbia University in the US and one of the research team, said: “Much of this carbonate will eventually [wash into] the ocean, ending up as limestone on the ocean floor. But Why Is Basalt So Important To Use To Re-minrelize My Soil? Norcal’s Finest Remineralizing Rock Dust: Igneous Basalt. “We are calling on nations to make inventories,” said Beerling. Regardless if it's only a trace amount that is needed, you need to make sure that your soil contains that trace amount. Crushed basalt is applied to an arable field in Norfolk as part of the research programme of the Leverhulme Centre for Climate Change Mitigation. They both do similar things, but using them in conjunction to get the best of both worlds is always a good idea. Please see this article in the Guardian for more info. It goes over the basics...

Zeolite, Spongolite and Bentonite give amazing water and nutrient hold ability and increase the cation exchange capacity (CEC), they also provide tiny hotels for beneficial microbes to live in. Applying finely ground Basalt Grit to your garden is like adding a fresh deposit of natural soil minerals. Basalt is comprised of Igneous rock that is found in many places around the world. The existing global supply of dust … Make sure to check your supplier for quality. “CO2 drawdown strategies that can scale up and are compatible with existing land uses are urgently required to combat climate change, alongside deep emissions cuts,” said Prof David Beerling, of the University of Sheffield, a lead author of the study. For this you need to learn Liebig's Law of Minimums. But he said some mining specifically to produce basalt rock dust would probably still be needed, using existing mine capacity rather than new mines. If you want it to break down slowly over a season or two, you want to get a courser grade chunky product. warned the US Senate about global warming in 1988. The finer dust in these products means that normal weathering processes will release minerals more rapidly. Basalt Rock Dust is an all natural soil amendment that is made from ground up volcanic rocks. The addition of Basalt Volcanic Rock Dust is a critical requirement to Western Australia’s mineral deficient soils as it rebalances soils with a bevy of trace elements and minerals. “The practice of spreading crushed rock to improve soil pH is commonplace in many agricultural regions worldwide. But climate scientists also agree that, in addition, massive amounts of CO2 need to be removed from the air to meet the Paris agreement goals of keeping global temperature rise below 2C. These igneous rock dusts remineralise the soil and supply trace elements that may be lacking. Depending on what your soil needs, and how long you want the dust to break down over time, you want to make sure to choose the correct grade of rock dust. However the science indicates that low rates of high value rock dust containing a … Basalt Rock Dust is made of the volcanic rock called basalt and is specifically used in the cultivation process of the Medicinal Mushroom – Cordyceps Militaris. Since basalt will break down easily in soils, it is a good choice for re-mineralizing flowerbeds and gardens. First you have to understand the basics of soil balancing. On May 18, 1980, Washington’s Mount St. Helens awoke from 120 years of dormancy and erupted, sending volcanic ash into the atmosphere and depositing it in 11 states. Basalt is one of the most common rocks on Earth, and waste dust from mining could be used for ERW, as could waste from cement and steel manufacturing. Glacial rock dust and basalt rock dust are broad spectrum, organic mineral fertilizers that everyone can use without a soil test. “The technology and infrastructure already exist to adapt these practices to utilise basalt rock dust. The chemical reactions that degrade the rock particles lock the greenhouse gas into carbonates within months, and some scientists say this approach may be the best near-term way of removing CO2 from the atmosphere. But the scientists said all approaches may be needed to beat the climate crisis. The use of basalt as a mechanism to reduce atmospheric CO2 and N2O, capturing carbon in situ and buffering the oceans downstream. These two rock dusts also benefit soil with their paramagnetism. Improve your soil with Volcanic Rock Dust! “Weathering provides a natural, permanent sink for the carbon.”. The “kitchen sink” approach when using rock dust isn't a bad thing, provided your soil tests justify their use. If not, your plants won't grow to their fullest potential. Use this popup to embed a mailing list sign up form. The cost depends on local labour rates and varies from $80 per tonne in India to $160 in the US, and is in line with the $100-150 carbon price forecast by the World Bank for 2050, the date by which emissions must reach net zero to avoid catastrophic climate breakdown. Basalt is the best rock for capturing CO2, and many mines already produce dust as a byproduct, so stockpiles already exist. The new research suggests ERW will be less expensive than either and, unlike energy crops, does not compete with food for land. The rock dust approach, called enhanced rock weathering (ERW), has several advantages, the researchers say. Planting trees and adding charcoal to soil also remove CO2 from the air, and these approaches could potentially be used in combination with ERW to maximise the impact. It also provides a source of silicon. “Planting trees is an excellent option for CO2 removal but is not sufficient on its own,” said the scientists. 2012) Rock dust for remineralization has traditionally been utilized at very high rates, up to 10 tons per acre. Dorrigo Basalt Crusher Dust and Palagonite - Biodynamic Agriculture Australia Ltd. Most rock dusts come in different grades. Silicon in plants can help plants resist drought, heat, and other issue that may arise. Farmers must be fully behind such a global effort or it will fail.”. Rock dust is used in coal mines to help prevent coal dust explosions by acting as a heat sink. Micro-nutrients can be just as important when looking to balance your soil. As your crops remove nutrients from the soil they will need to be replenished. Basalt Rock Dust is made of the volcanic rock called basalt. Retrieval of rock grains after 120 days indicated extensive colonization by fungi (2.0 ± 0.1 m hyphae/g rock) similar to that reported for crushed basalt‐filled mesh‐bags buried in soils beneath established (10–30 m high) trees with). Gaia Green Basalt Rock Dust is mined from an ancient volcanic deposit in the mountains of British Columbia, Canada. Macro means large or big. Other proposed ways of pulling CO2 from the atmosphere at similar rates include using chemical solvents to capture it directly from the air, or growing energy crops, burning them to produce electricity and then burying the CO2 emissions. Despite the destruction, though, nature’s regenerative abilities quickly took over. From this, it may be inferred that if the deficient nutrient is supplied, yields may be improved to the point that some other nutrient is needed in greater quantity than the soil can provide, and the Law of the Minimum would apply in turn to that nutrient. Basalt is one of the most common rocks on Earth, and waste dust from mining could be used for ERW, as could waste from cement and steel manufacturing. Basalt rock dust as a source of natural nutrients for plants Basalt is an igneous rock. But how big these waste stockpiles are is unknown. Hansen, who famously warned the US Senate about global warming in 1988, said improving soil could also underpin food security for billions of people.
