Atami Kilomix

31 posts in this topic

I told him about the suspicion that Kilomix had mineral salts in it, and so he took the question straight to Atami on my behalf (i figured he would get more luck than us in getting an answer out of them).

Here is the email

The Kilomix substance is organic, also the nutrients we add are organic.

Ofcourse we looked to the added nutriens of Biobizz All-mix. In our formula

we use a higher level of trace-elements and a higher level of P by adding

Guano to the Kilomix.

So - the adding of Bat Guano is not really massively organic - but no mineral salts are used, and certification of some kind looks to be forthcoming.

I wouldn't use it because it contains Guano! :D

Cheers for the info on that though mate :stoned:

A few bits of info about Bat Guano lol

The caves of Jamaica, like other caves around the world, face threats to their physical structure, their biodiversity, and the paleoclimatic and fossil records that they preserve. The damage being done to these ancient, underground systems has one source and that is us. The ways that humans cause damage to caves may be broadly grouped into two categories: external and internal.

External factors are activities such as removal of forest cover on, and upstream of, the caves. Deforestation on the land immediately above the system affects the temperature and humidity of the cave below. Deforestation upstream of hydrologically active systems results in the filling up of the cave with silt. A good example of this latter occurence is Clifton Cave in Dolphin Head. Within a generation, it has gone from being a beautiful, biologically rich underground world, to a mud-filled crawl less than a metre high... that which remains of it. This was caused by the complete removal of the trees that once slowed, and held, the seasonal run-off of rain.

Internal factors in the destruction of Jamaican caves are excessive human visitation for the purposes of tourism, and more importantly in Jamaica, mining for bat guano. It is unfortunately little known that the caves of the island are habitats for much more than bats. In caves that have rich deposits of guano, there live many fascinating invertebrates.

Much of the biodiversity of the Jamaican caves is dependent on bat guano as the food resource. The wholesale removal of the bat guano results in the elimination of not only the bats that made it, through repeated disturbance of a creature that lives on the metabolic edge and is easily driven over that edge, but also results in the elimination of almost every species that lived on it. The cave is effectively sterilized and although the bats might eventually return the invertebrates that were lost are gone forever. I invite any wholesalers, retailers, or buyers of Jamaican Bat Guano to join me in a visit to Bristol Cave if you doubt this. Where there was once a colony of tens of thousands of bats, where there was once a myriad of inverterbrate species, now there is nothing thanks to guano mining.

As well as supplying a habitat for living creatures, old guano deposits contain a record of the climatalogical conditions of the island that extends back over thousands of years. They also contain the fossilized remains of ancient creatures that once called these caves home.

Physical damage that can be done to formations, and bone breccia [1], will be unavoidable during the mining process.

There is more to be found in the caves, and the guano, than just a fertilizer that will likely be used for the production of recreational drugs; remove the guano and you remove tens of thousand of years of Jamaica's history and much of the life that still exists there. This damage will be irreversible.

The current biological status of the source caves for the commercially available Jamaican Bat Guano found at hydroponic and gardening stores across North America is unknown, but prudence suggests a careful survey to ensure that the cave systems remain healthy.

Caves, as well as being beautiful, are wonderful biological islands capable of creating their own endemic species, archives of our planet, and are in great need of our protection.

Before purchasing any bat guano fertilizer, one must consider the true need, and the consequences, of using such a product.



and it may also be harmfull to your health lol

Written by Garry K. Smith ©

Around the world, hundreds of thousands of people each year are affected by a fungal infection called Histoplasmosis. In many areas of South America, Asia, Europe, Africa and East Central United States, the disease has been found in the droppings of domestic birds, such as fowls as well as starlings and other birds which often nest around houses. To humans this microscopic fungus is potentially fatal if the infection is not treated.

At this stage you are probably saying to yourself, "what has this to do with caving".?

Evidence exists that the fungus Histoplasma capulatum grows in guano, (bat droppings) and that it may be spread by bats flying from one roost cave to another. The fungus can survive in the intestinal contents of bats as well as transmitted to other locations by wind. To date the fungus has been detected in some caves inhabited by the Bent Wing Bat (Miniopterus schreibersii blepotis) however there is no conclusive evidence that it is confined to guano of this bat species.

Other names for this disease include:- "Histo", "cave disease", "cave fever", "Darling's disease", "Ohio Valley disease, "Tingo Maria fever", "reticuloendotheliosis" and "reticuloendothelial cytomycosis".

Habitat of the Fungus.

Histoplasma capulatum is an organism which grows in soil containing a high nitrogen content, generally associated with guano of birds and bats.

The fungus reproduces by releasing spore of 2 to 5 micron in size, to the air. Ideal conditions for this to occur is in caves with high humidity (ie 67% to 87% or more), temperatures of around 20 to 29 degrees C and the presence of dry guano. Many overseas reports have recorded high concentrations of the fungus in guano around poultry sheds. In "open" environments the occurrence of the fungus is generally restricted to between latitudes 45 degrees N and 45 degrees S. Outside of this tropical zone, concentrations of the fungus is restricted to appropriate environmental conditions which can occur in "closed" environments such as caves. This is due to the stable conditions which exist inside caves, where as the surrounding countryside may be too dry or cold for sustained proliferation.

Effect on the Human Body

Histoplasmosis is a fungal infection which can affect the whole body and is caused by inhalation of an aerosol of soil, dust or guano which contains fungal spore. When the airborne spore is breathed in by cavers it may infect the lungs. The degree of infection in humans varies widely, depending on the individual's immune status and degree of exposure to the fungal spores.

In most cases the spore are introduced in such a quantity as to produce a mild form of the disease and thus builds up the bodies immunity to the fungus. This form of infection is referred to as Asymptomatic and the infected person experiences no noticeable symptoms.

When a person is subjected to high exposure, some spore reach the alveoli and begin to germinate. Conversion to an invasive yeast phase takes place, and multiplication occurs by binary fission.

The second form of infection is Acute Pulmonary Histoplasmosis. Symptoms may occur two to three weeks after infection and include a general feeling of being unwell as if suffering a mild influenza with a raised temperature, malaise or tiredness and pleuritic chest pain. In most cases the person with a mild infection quickly recovers with no treatment.

The more severe third form of infection is called Chronic Pulmonary Histoplasmosis. The condition of persons with high exposure and/or low immunity to the fungus, may quickly deteriorate to include fever, night sweating, headaches, shortness of breath, lack of energy, muscular aching, weight loss, dry coughing and severe pain around the lungs. If untreated, the lungs continue to be slowly destroyed and death can occur months or years later from bacterial pneumonia or heart failure.

The most severe form of infection is called Acute Disseminated Histoplasmosis and the yeasts are spread throughout the body via the blood stream.

Overseas statistics show that in a small percentage of cases the disease may disseminate and infect the lymph glands, liver, spleen and other vital organs, resulting in fever and weight loss. Chronic respiratory infections resemble chronic pulmonary tuberculosis. The disease progresses over a period of months to years, possibly with periods of remission. This form is more common in males over 40 and often results in death. Symptoms at the chronic stage may vary, depending on the organs involved. Unexplained fever, anaemia, heart inflammation, meningitis, pneumonia and mucosal ulceration of the mouth, bowel or stomach may be seen. The infection is not transmitted from person to person and there is no immunization presently available.

It may be of interest that Histoplasmosis is not only confined to humans, as other animals such as dogs, cats, rats and foxes are also susceptible to infection.

Maybe a concerted email and letter campaign against the companies that use guano might be a good way to go.

If this, and some of the other growsites dotted around the internet mass emailed Atami about the guano in their kilomix, pointing out that its not acceptable to use it, then maybe they would change their formula - difficult to ignore several hundred customers complaining about something lol

Trouble is with Guano, the Americans love it & swear by it. Could be a case of banging your head against a brick wall!

But maybe Atami would reconsider its use if your mate is in a good position to do so G lol

I have a kg of 'sterilized' bat-guano - given to me by the guy in the local hydro-shop....

But I have been told from another source that you can get both 'grow' & 'bloom' bat shit.... lollol

No idea what mine is - haven't been back to ask tbo.. :unsure:

Question is should I use it - bit of an ethical dilema.... ;)

I doubt if it would make much difference Bish.

sales@atami.com is their email address - if the sales bods get enough complaining messages about the guano then who knows - got to be worth the time it takes to send out an email - especially if its all backed up with relevant facts and links lol

Just sent them this:

Good afternoon.

I am an organic grower, and was tempted to go for your Kilomix product, as an alternative to Biobizz Allmix recently.

That is until I discovered that you use Bat Guano as part of the makeup of the product.

How can you try and sell a product as being organic when it contains ingredients that cause serious damage to the environment in the way they are obtained?

Organic farming and growing is not just about using natural products instead of chemical salts - its about using sustainable resources that do not damage delicate ecosystems. Bat Guano definately does not fall into this category.

I would urge your company to stop using this ingredient in your kilomix product in the strongest possible terms, or at least stop saying its organic when this ingredient makes it anything but.

I realise that Bat Guano is an extremely good source of P and other trace elements, that can be difficult to add to an organic product without resorting to chemicals such as potash, but believe me, 99% of organic growers would rather your product had slightly lower levels of P and did not contribute to destruction of bat habitats and the ecosystems that evolve there. It completely goes against all of the principles of organic growing, and I suspect you may have difficulty obtaining any organic certification while this ingredient is still used.

Many growers have become disillusioned with Biobizz's product lately, and a proper organic growing medium has yet to be marketted by any of the major nutrient manufacturers that can compete with it.

Kilomix could be that product, but not while it uses ingredients that are not environmentally friendly.
