CARBON CAPTURE gardening for 2021!

CARBON CAPTURE gardening for 2021!

After a year where new and experienced gardeners have found solace from Covid19 by spending their extra free time actively gardening, Carbon Capture gardening with REMIN volcanic rock dust (REMIN) is set to be the new trend setter for 2021.

Organically certified REMIN is freshly crushed and finely screened, ancient volcanic rock that is sourced in the UK.   From allotmenteers, to stately homes, to horticulture, to farming, REMIN now has an established following that have seen a significant improvement in their crops for themselves.  Feedback includes increased yields of tastier, healthier crops that are noted as more resistant to pests and diseases.  These benefits are attributed to the wide range of natural minerals and trace elements that REMIN adds to our soil and compost.

Healthier crops are not the only benefits that REMIN provides, however.   Via the recently signed service agreement between REMIN (Scotland) Ltd with Newcastle University, the University now quantifies the inorganic carbon that REMIN captures from the carbon dioxide, CO2, in the air we breathe.   Atmospheric CO2 is one of the greenhouse gases that society has released by, for example, burning coal and oil.   These greenhouse gases are now heating up our planet with serious consequences for our climate.  By adding REMIN to soil and compost, growers are, over time, increasing the atmospheric CO2, that is being captured back into the soil.

Here is the scientific bit. We all know organic matter in soil decays and that this decay is driven by the life in the soil. A by-product of this decay is the release of CO2. Instead of being released into the atmosphere, this CO2 is captured by REMIN and it weathers the REMIN via a process now known as Enhanced Rock Weathering (ERW).

During the first stage of ERW, calcium silicate (Ca2O4Si), naturally occurring in REMIN, releases the silicate leaving the calcium to bond with the CO2 to form calcium bicarbonate Ca(HCO3) 2 as an inorganic carbon in solution. During the second stage, the calcium released from the silicate forms calcium carbonate, (CaCO3), also known as calcite and this time it is as pedogenic soil mineral contains inorganic carbon that remains stable in soil for thousands of years. In short, unlike the carbon captured by planting trees, as part of the tree life cycle, carbon captured by REMIN to form calcite, remains stable in the soil for thousands of years.

Newcastle University advises that 70kg to 230kg of CO2 is captured per tonne of REMIN applied.  In 2018 the Royal Society published a paper on certain rock dust’s ability to capture carbon.   In the same year Sheffield University introduced this rock dust to the Climate Change Conference in Poland followed by a paper in Nature, July 2020.  So, it is a new scientific understanding that underpins the additional benefit now being recognised for REMIN.

Organic carbon is carbon that forms, or has formed, part of living tissue.  As well as crop yield increase noted when adding REMIN, as atmospheric CO2 and H2O forms plant tissue via the well-recognised process, “photosynthesis”, it is noted that REMIN also boosts soil life, everything from bacteria to worms.  As carbon is the backbone of DNA, that makes up all life, the boosted soil life, whether living or dead, constitutes organic carbon that is sustainably captured in the soil.  Soil that has been treated with pesticides and herbicides is often depleted of minerals and trace elements due to the unintended death of beneficial soil organisms that make the minerals available to the plants.   REMIN is found to be a catalyst to stimulate the depleted soil life back into action and so help the soil life make the health-giving minerals and trace elements bioavailable to plants.

It is worth taking this explanation a little further, especially when considering tree planting for carbon capture.   It has been high-lighted recently how the process of photosynthesis, that, by definition, captures CO2 to make plant tissue, also creates exudates that contains carbon, that the plant pumps out through its roots into the soil.   These exudates attract soil life whose job it is to release the essential minerals and trace elements that they have extracted, both from soil and from REMIN, to the plant in exchange for the sugar feed they get from the exudates.

This MICROBES / MINERALS relationship is the next piece of this incredible jigsaw of soil that we are all still putting together.   The healthier the plants, the bigger their root mass and yes, mycorrhizal fungi come in here too.  With REMIN, healthier trees, grow bigger above and below ground.  In summary – with REMIN – bigger, healthier trees pump more exudates out into the soil, where the soil life, boosted as it is by REMIN, exchange more minerals and trace elements and, together with the inorganic carbon that the REMIN is naturally capturing as it weathers, the more CO2 is captured from the atmosphere all round!
