12 Ways This Little Known Mineral Can Improve Your Soil

Clinoptilolite zeolite is a microporous aluminosilicate mineral with a kind of funny name, but what it can do to benefit your soil is very serious.

A handful of pure clinoptilolite zeolite can contain a surface area of over 10 million square feet!

Zeolite has an extremely high porosity and cation exchange rate. This plus a negative charge means it can draw in and hold nutrients, oxygen and water until they are required and absorbed by plant roots.

1) Save Water

Increase water holding capacity of your soil and reduce watering requirements by up to 50%

2) Improve Absorption

Absorb more H2O, increase infiltration and improve water permeation. Zeolite traps and holds moisture within it’s molecular structure allowing plant roots to tap into the stored H20 as needed.

3) Retain Nutrients

Zeolite has a very hight cation exchange rate and a negative charge, this allows the mineral to absorb nutrients and hold on to them until required by the roots. Reduce nutrient leaching and prevent water table pollution by potassium, phosphorous, nitrates & nitrites.

4) Balance pH

Naturally balance the pH levels in the soil and prevent spikes in pH which can help correct and maintain a balanced environment for maximum root growth.

5) Remove Toxins

Because zeolite has a helical and negatively charged molecular cage it adsorbs and locks in ammonia and harmful heavy metals, effectively removing them from the surrounding soil.

6) Reduce Aridity

Improve soil aeration and repair arid soil.  Mixing zeolite into soils improves root health allowing more water and nutrients to get to the roots.

7) Gnat Deterent

Keep soil surface free of mildew and gnats by sprinkling zeolite powder over the top layer.

8) Control Nutrient Uptake

The zeolite in the soil will adsorb then slowly release fertilizers, insecticides, pesticides, and growth stimulators as needed by the plant.

9) Balance Light Soil

Improve the nitrogen balance in light and sandy soil.

10) Correct Bad Soil

Improve the production capacity of soils devastated by acids and other contaminants.

11) Reduce Compacting

Prevent soil compaction and increase porosity and aeration allowing roots to spread and grow healthier and longer.

12) Compost Organics Better

Improve the breakdown of compostable elements in soil & reduce odors. Increase the level of good bacteria and reduce the bad bacteria. 

The Benefits of Zeolite in Soils

Add 10 – 15% clinoptilolite zeolite to any soil blend or dirt to improve the qualities and performance of the soil.

Adding 10 – 15% clinoptilolite zeolite by volume to soil or fields can improve the health of the roots and result in healthier plants. Always source the purest zeolite. KMI Zeolite suppliesthe highest natural form of clinoptilolite zeolite available, at 97%+ purity. You can buy Zeolite here for your home or commercial applications.

ABR Ashburton zeolite study shows increased weed yields

The following story was published on Thomson ONE: For information on Thomson ONE go to

Ashburton Ventures Inc. has released the analysis of the final weight of dried
marijuana harvested from plants involved in a study of cannabis cultivated
with zeolite from the Z-1 zeolite quarry near Cache Creek, B.C.
Plants enriched with a zeolite-carbon blend produced up to 29% more dry
cannabis (in a 0.9% to 29.4% range), with an average per-plant increase of
7.8% compared to control plants grown in straight coconut husk fibre (coco
coir). Plants enriched with straight zeolite produced up to 19% more dry
cannabis (in a 2.3% to 19.0% range), with an average increase of 7.1% in total
harvest yields compared to the control group average.
According to Albert Kasprowicz, BSc, "Each of the study's eighteen test groups
and two control groups produced a cluster of six data points within a range.
The average value of each data cluster is the key information, because an
operation's total harvest is proportional to the average plant's yield. We can
now predict with confidence the effect of ten distinct soil recipes on total
harvests, when applied on an operation-wide scale. Two of those recipes stand
out from the rest."
The study produced a scatter chart of data points measured in grams,
representing per-plant marijuana yields in twenty groups of six plants each.
The study was split between two strains, Meltdown and CBD God, grouped
according to levels of enrichment with straight zeolite, straight carbon, or a zeolite-carbon blend mixed into a base soil of coco coir. 

To obtain data, whole plants were hung to dry for one week in a controlled-humidity
environment before flowers were removed and weight measurements taken under Kasprowicz' supervision.
Kasprowicz stated, "Straight zeolite and zeolite-carbon blends gave us the
biggest gains, each with an average production increase of over 7% consistent
across both strains. Our next phase of research will attempt to push this
number higher by adjusting zeolite particle sizes. We believe a 10% production
increase may be a realistic goal. Our pending order for 20 tons of Z-1 Zeolite
has been adjusted to include a blend of fine particle sizes specific to our
Ashburton President David Gdanski stated, "Our study demonstrates a simpler
route to the higher yields cultivators are after. In an industry where costs
of production are high, typically exceeding 50% of the wholesale value of
marijuana produced, a 7% or 10% increase in yields and revenue can equate to a
15% or 20% increase in net profit. We're extremely pleased about what our
study says about the potential return on investment for Z-1 Zeolite customers
in the commercial marijuana sector."
Ashburton currently awaits Kasprowicz' analysis of data recently released by
MB Labs, to better understand the mechanisms by which zeolite and carbon act
to increase marijuana yields.

BC Bud Co Zeolite Research


VANCOUVER, B.C. – ASHBURTON VENTURES INC. (ABR-TSX:V) (ARB-FRANKFURT)  (“Ashburton” or the “Company”) is pleased to announce that BC Bud Depot’s Research and Development facility on Salt Spring Island has placed an initial twenty-ton zeolite order based on the encouraging results of an ongoing study into the effects of Ashburton’s Z-1 Zeolite and ZMM T-Carbon on cannabis growth and productivity. 

The study has entered its third and final phase with the current harvest of all 72 plants providing scientific data. Phase Two samples, of plant tissue and soil, are currently at MB Labs in Sidney, BC, a Health Canada certified cannabis analytics laboratory.

 Phase One data revealed notable trends corresponding to the Z-1 zeolite and zeolite-carbon enrichment of the growth medium. Reduced pathogens in liquid runoff from amended soils suggests a cleaner root zone with fewer factors to inhibit cannabis productivity. Highlights include:

·         Up to 85% less Staphylococcus bacteria;

·         Up to 90% less of total Coliforms;

·         Up to 48% less of Lactose Fermenters;

·         Up to 62% less Yeast and Fungi.

The Company’s Z-1 Zeolite also prevented wasteful leaching of five critical nutrients to cannabis production – nitrogen, potassium, phosphorus, calcium and magnesium – allowing higher levels to remain available for plant uptake. Plants in straight coconut fibre lost up to 438% more nutrient during irrigation.

 According to facility operator Edward Bielert, “We’re seeing healthier plants that are noticeably heavier as we hang them up to dry. It’s safe to say that zeolite makes some difference to yields, but we harvest in stages, top buds first, so we don’t have final weight numbers yet.”

Bielert added, “What we do already know, and what impacts us immensely, is the labour we’ll save by planting our whole farm with zeolite. We were surprised by how much water zeolite soaks up – plants potted with zeolite required irrigation only half as often. That’s hundreds of man-hours saved in a crop cycle. Z-1 Zeolite will revolutionize operations here.”

 Initially BC Bud Depot’s Research and Development facility have placed a twenty-ton Purchase Order of Z-1 clinoptilolite Zeolite. Processing this premium-grade zeolite will begin at the Z-1 Quarry imminently, as the Cache Creek evacuation order has been lifted.

 “We’re pleased to take our initial order from the cannabis industry. Mr. Bielert has strong ties to the Canadian Licensed Producer [LP] community,” stated Tim Harvey, Chief Operations Officer. “Having a cannabis farmer of his stature to showcase our product on a large scale, and having the science to establish quantitative benefits to marijuana production puts us in a strong position to convey the value that Z-1 Zeolite can add to LP cannabis operations.”

Cannabis Study Shows Decreased Leaching with Zeolite

Ashburton Receives Chemical Results for Cannabis Study, Confirms Success in Decreasing Nutrient Leaching

Vancouver, British Columbia (FSCwire) – ASHBURTON VENTURES INC. (ABR-TSX:V) (ARB-FRANKFURT) (“Ashburton” or the “Company”) is pleased to announce the release of a second set of laboratory data from MB Labs in Sidney, BC. The chemical analysis lists levels of sixteen major and minor plant nutrients detected in liquid runoff captured from cannabis plants involved in a study of zeolite and carbon in marijuana cultivation.

Clinoptilolite zeolite used in the study is from the Z-1 Mine near Cache Creek, BC, jointly operated by Ashburton Ventures and ZMM Canada Minerals Corp.

Sample data indicates a high retention of key macronutrients in the root zone of cannabis plants potted with zeolite and zeolite-carbon blends. Control group samples revealed higher nutrient leaching from plants potted in straight coconut fibre. Leached nutrients are drawn out of the root zone with liquid runoff when the potting medium is fully saturated during plant irrigation. Zeolite’s capacity to combat leaching allows plants greater access to nutrients and prevents waste.

“It appears that zeolite keeps important nutrients where they’re needed – available to the roots,” said biologist and project manager Albert Kasprowicz. “Consider nitrogen. Substrates without the zeolite-carbon blend leached 300% more Ammonia and 63% more Nitrate.”

Kasprowicz also noted “Zeolite has impacted phosphorus as well. Phosphorus plays an important role in the conversion of light into chemical energy and promotes the formation of flower mass in cannabis. Organic growers invest heavily in fertilizers such as bat guano and rock phosphate. Phosphorus is a precious nutrient, so we pay special attention to leaching versus retention and uptake. In our study, control substrates leached 56% more phosphorus than zeolite-carbon substrates. Zeolite and carbon are catching significantly more phosphorus before it escapes as waste.”

The laboratory data also revealed zeolite’s high capacity to retain potassium, a third critical macronutrient known to cannabis growers as the “quality-enhancing nutrient.” Potassium supports plant respiration, activates enzymes and protein synthesis, and facilitates nutrient transport between cells.
Control samples leached 438% and 261% more potassium than straight zeolite and zeolite-carbon blends, respectively.

Ashburton COO Tim Harvey stated “Despite being lower, the 261% figure is especially interesting because that’s from plants potted with zeolite and carbon from wood ash, which is loaded with potassium. Despite the extra potassium, there was a startling capacity to hold potassium in the soil. That’s excellent news for growers because it’s hard to overdose plants on potassium, and it helps in growing strong-limbed plants to carry the heavy bud loads we’re after. Potassium also produces the textures, terpenes and cannabinoids of an elite-quality marijuana.”

“The numbers paint a compelling picture so far,” stated Kasprowicz. “They’ve exceeded my expectations of the impact of zeolite. This upcoming round of data will add weight to our initial findings, expand our understanding and set us up for the next phase of our study.”

Marijuana Plant

Cultivating Healthier Cannabis Harvests


June 27th, 2017, VANCOUVER, B.C. – ASHBURTON VENTURES INC. (ABR-TSX:V) (ARB-FRANKFURT) (“Ashburton” or the “Company”) is pleased to announce the release of data obtained from laboratory analysis at MB Labs in Sidney, BC, of the microbiology of liquid runoff captured from cannabis plants involved in a study of zeolite and carbon in marijuana cultivation.

The data indicated significantly lower concentrations of bacteria, fungi and yeast found in liquid runoff from plants enriched with zeolite and a zeolite-carbon blend, as compared to control samples. The clinoptilolite zeolite used in the study is from the Z1 Mine near Cache Creek, BC, operated jointly by Ashburton Ventures and ZMM Canada Minerals Corp. ZMM Canada supplied the carbon.

“This is a wonderful data set,” said biologist and project manager Albert Krasprowicz. “It illustrates how zeolite allows much cleaner cultivation. As growers, we typically use moist substrates and grow a dense canopy, but this invites bacteria that can lead to outbreaks and decreased production. With zeolite or a zeolite-carbon blend, bacteria levels fall dramatically. We anticipate healthier harvests from plants with a reduced bacterial burden.”

“Data from control samples were in a completely different range,” Krasprowicz noted. “With zeolite and carbon, we see 85% and 90% less of total staph and coliforms. We’ll take a larger set of samples next week and if we can replicate these findings, it’ll be a game-changer. Everybody’s happy with a cleaner substrate and vigorous, resilient plants.”

While trends did emerge from the data, Krasprowicz also noted some anomalies. “Dealing with composted coconut fibre, you would expect some data outliers. It’s imperative that we collect more data to confirm the overall trend.”

Laboratory analysis was performed by MB Labs in Sidney, BC. MB Labs also performed a detailed chemical analysis. Results are due next week.

Salt Ice Melt Pollution

Salt Ice Melt is Contaminating North American Lakes

For the past 50 years the US has been using more salt to melt ice, millions of tons more. While salt does melt the ice it also gets swept away, eventually making its way into streams and lakes.  Studies show that salt ice melt is contaminating lakes and streams at an alarming rate, and that just under 8,000 lakes in North America alone may be at risk of over salinization. Since the salt cannot be filtered out these effects may be irreversible, it is important to curb the use of salts through alternative ice melt options.
