Diatoms are fossilized algae They are used in the form of soil and with different uses, such as organic and natural fertilizers or ecological insecticides for crops, among many other common uses. Since they are used in the form of white lands, they are also called White Lands. Therefore, it is a very beneficial natural fertilizer for soils.
In this Green Ecologist article, we will talk about what is diatomaceous earth and what is it for, focusing mainly on the field of gardening.
The Diatoms (Diatom) are single-celled algae that are part of marine phytoplankton. Currently, some 20,000 living species are known and they are an important constituent of the marine food chain. Although Diatoms are single-celled algae, they can be found by forming colonies in filaments or ribbons (eg. Fragillaria), zig-zag structures (eg. Tabellaria), stellate colonies (ex. Asterionella) or fans (ex. Meridion).
One of the most important characteristics of these organisms and that gives them a large part of their properties as a fertilizer, is his opal silica cell wall (hydrated silicon dioxide), known as frustule. These walls have a great variety of shapes that give them different aspects to the microscope, although in general they consist of two asymmetric parts with a division between them, which is what gives the group its name.
The fossil finds suggest that Diatoms have their origin during or after the Early jurassic. In addition, the communities of these organisms are frequently used to study environmental conditions, climate change or evaluate the quality of waters.
How are diatoms transformed into soil? As we have commented, Diatoms formed marine phytoplankton thousands of years ago, in Prehistory, but they were not only present in the seas, but also in fresh water. Therefore, Diatoms are one of the first organisms that inhabited the Earth.
Over time, as the seas and lakes dried up, these algae formed settlements on their bottoms and, with the accumulation of layers of land over time, continued fossilizing their silica exoskeletons. It is for this reason that we can find Diatoms under various layers of earth in various places where there was a sea or lake before. Due to their high content of organic silicon and calcium, they acquire that coloration of White land.
Now that you know what diatomaceous earth is and what exactly these are, we will tell you what diatomaceous earth is for. The most common uses of diatomaceous earth They are the following, although there are many more:
Diatomaceous earth can be used as an effective ecological and natural insecticide. It is very effective in getting rid of the annoying insects that attack and harm many of our crops, especially in warm seasons.
What is diatomaceous earth for other than being an ecological insecticide? Well, this use may surprise you a bit, but it is used in animals and even people use it.
Thus, a lesser known use of diatomaceous earth is its use to eliminate parasites that harm the health of our animals. Yes, diatomaceous earth is very useful to eliminate fleas that parasitize our cats or dogs in the summer seasons or to eliminate parasites from small pens or chicken farms. In addition, it can be used as a food supplement and is effective in eliminating intestinal parasites from our pets. We can also take it ourselves for the same purposes, but as long as it is its version suitable for consumption.
Diatomaceous earth is a perfect fertilizer for farmland. On the one hand, it provides nutrients, such as calcium or silicon, which are very beneficial for the soil, and on the other, it improves cation exchange, facilitating the absorption of nutrients by the soil, improving the aeration level of the soil, its sponginess and water retention. .
Although cultivated soils already have their macronutrients, if we do not have the presence of some micronutrients, the plants will not be able to assimilate them. Diatomaceous soils provide important micronutrients to the soil and allow plants to assimilate other macronutrients present in the soil. In particular, diatomaceous earth helps the assimilation of phosphorus, nitrogen and potassium.
In addition, as diatomaceous earth is a natural product without additives, we will also be contributing to improve the health of the soil.
The diatomaceous earth or diatomaceous earth contributes up to a total of 40 mineral nutrients, of which 6 are considered essential primary and secondary in agriculture and 13 are primary and secondary trace elements. Some of these nutrients are:
A very frequent question is knowing what is the indicated dose of diatomaceous earth for garden and cultivation and for human consumption and for animals. The best thing is that you talk to a specialist who will advise you depending on the case, for example on the site where you are going to buy diatomaceous earth, but at Ecologista Verde we give you an orientation of the most common of the doses of diatomaceous earth for the garden and crops and for other uses common:
To use it as a dusted fertilizer, use a mixture of the substrate or soil soil with diatomite in a proportion of 40 or 50 g of diatomite for every m2 of garden soil. To use it in a spray form, use 40g per liter.
For the control of terrestrial pests, use 100 g of diatomite for each m2 of soil and for aerial pests use between 10 and 40 g of this soil for each liter of water to spray, adjusting the dose according to the size of the pest.
There are two types of diatomite, the food grade diatomaceous earth and non-food grade diatomaceous earth. So if you are looking for this product for human consumption, make sure that the packaging indicates that it is food grade and, therefore, suitable.
The best thing is that if you decide to take it, talk to your regular doctor about the most appropriate dose for you, since depending on your usual diet and your general health, this may vary. In addition, it is necessary to follow the indications regarding the dose or dosage indicated on the container, since it is recommended by the manufacturer of this product for human consumption. As an average idea, the usual thing is to take a teaspoon a day and take it for a maximum of 30 days in a row.
In the case of animals, the dose can vary greatly depending on the species, so it is always better to follow the instructions of the veterinarian who usually monitors the health of the animal you want to treat with this natural product.
As an example, the dose of diatomaceous earth for hens as an external antiparasitic is a 2% solution in water, as an internal antiparasitic and nutritional supplement 5% of the food dose is mixed. In the case of the dose of diatomite for cats, this is 1/2 teaspoon for puppy cats for a month and two teaspoons twice a day for a month for adult cats. Finally, the dose of diatoms for dogs is indicated for the treatment of one month and the daily dose by weight is indicated. If the dog weighs less than 4.5 kg, give it between 1/2 and a teaspoon, if it weighs between 4.5 kg and up to 8.5 kg two teaspoons, between 9 kg and 22.5 kg the dose is one tablespoon to a tablespoon and a half, between 23 kg and 45 kg the amount is two tablespoons and for dogs over 45 kg the dose of diatomaceous earth is between three and four tablespoons.
If you want buy diatomaceous earth to use in your garden or orchard, or for your animals or own consumption, we recommend that you go to stores specializing in gardening and agricultural products.
