What is vermiculite and how does it retain water in the soil?
Vermiculite is a naturally occurring mineral belonging to the phyllosilicate group. It has the remarkable property of being able to significantly expand its physical structure when exposed to high temperatures, a process known as "exfoliation." During this process, the vermiculite expands many times its original volume and takes on a structured, porous form that allows it to retain large amounts of water and nutrients , making it a valuable additive for garden and agricultural soils. We originally knew it as expanded clay.
In the soil, vermiculite works in several ways to improve plant health and growth:
1. Water retention: Due to its porous structure, vermiculite can retain large amounts of water. This stored water is then gradually released to the plants. This can be particularly useful in dry or sandy soils that tend to dry out quickly.
2. Nutrient storage: In addition to water, vermiculite can also store nutrients. It has the ability to bind cations (positively charged ions), including many nutrients important to plants such as potassium, calcium, and magnesium. These nutrients are then gradually released to the plants, helping to ensure a consistent nutrient supply .
3. Improve soil structure: Vermiculite can help improve soil structure. It helps loosen the soil and improve aeration, which promotes root growth and prevents waterlogging.
4. pH neutrality: Vermiculite is pH neutral, meaning it doesn't affect soil acidity. This is important because many plants are sensitive to changes in pH.
Overall, vermiculite can help significantly improve conditions for plant growth, especially in soils that naturally retain little water or nutrients. It offers a natural and sustainable way to improve water retention and nutrient supply in the soil, promoting plant growth and health.
Mineralogical composition of vermiculite
We already mentioned above that it is a naturally occurring mineral and belongs to the group of phyllosilicates. It is a member of the phyllosilicate mineral family and belongs to the same family as the equally well-known mineral mica.
The chemical formula of vermiculite is (Mg,Fe,Al)3(Al,Si)4O10(OH)2 4H2O. This indicates that the mineral contains magnesium, iron, and aluminum, as well as silicon, oxygen, and hydrogen. However, the exact chemical composition can vary depending on the specific conditions under which the mineral was formed.
What to do about dryness in the garden
STEINKRAFT BODENKRAFT PLUS water storage pellets with zeolite and vermiculite:
This product combines vermiculite and zeolite:
BODENKRAFT PLUS water storage pellets consist mainly of vermiculite and zeolite, two minerals known to be excellent natural water storage agents.
Here are some of the advantages these water storage pellets offer due to their specific properties:
1. Moisture retention: The water-retaining ability of vermiculite and zeolite is remarkable. They can absorb and retain up to 50 times their weight in water. This moisture is then gradually released to the plants as needed. During periods of irregular rainfall or in arid areas, this can be particularly useful to ensure plants always have access to water. This reduces the need for regular irrigation and minimizes water waste.
2. Nutrient storage and delivery: In addition to their ability to retain water, these pellets are rich in minerals and trace elements. They can absorb and store nutrients, then release them gradually over an extended period.
This improves soil fertility and enables optimal nutrient uptake by plants, which helps reduce fertilizer use and, of course, leads to more natural plant development.
3. Soil improvement: Vermiculite and zeolite help improve soil structure. They loosen clay soils and improve aeration, which helps prevent waterlogging and promotes root growth. The improved structure also makes it easier for plant roots to spread through the soil, resulting in healthier, stronger plants .
4. Temperature control: Thanks to their heat-insulating properties, the pellets help protect the soil from extreme temperature fluctuations. They prevent the soil from cooling down quickly, which can be particularly useful in cold climates. Especially when planting cucumbers and tomatoes, the soil can sometimes get quite cold, and the pellets are very helpful in maintaining a consistent soil temperature for these delicate plants.
5. pH neutral: Vermiculite and zeolite are virtually pH neutral, meaning they don't affect the soil's pH. This is important because soil pH can affect the availability of certain nutrients to plants. You've already read about this above.
BODENKRAFT PLUS Water Storage Pellets are therefore a valuable tool for anyone looking to improve the health and productivity of their garden , regardless of whether they live in a dry or humid climate. They offer a simple and sustainable solution for improving water retention and nutrient supply in the soil.
Questions and answers:
1. Question: How much of the BODENKRAFT PLUS water storage pellets should I add to my soil ?
Answer: Generally, the pellets should make up about 10% of the soil volume. I like to add them directly to the roots when planting (2 handfuls) so that the moisture and nutrients encourage the fine roots to bond well with the soil.
2. Question: Can I also use the BODENKRAFT PLUS water storage pellets in my indoor plants?
Answer: Yes, the pellets are safe to use indoors. They can help retain moisture in the soil and optimize the nutrient supply for your houseplants. Potted plant soil, in particular, can tolerate a little pimping up, and if you forget to water it once, it's not such a big deal.
3. Question: Are BODENKRAFT PLUS water storage pellets safe for all plant species?
Answer: Yes, the pellets are suitable for all plant species. They are made from natural minerals and contain no harmful chemicals that could negatively affect plant growth. They also contain no binding agents. They're vegan, by the way. Which I think is great for soil. I don't want any dead animals in my vegetable soil, and actually, not in my plants and flowers either.
4. Question: How often do I need to add the BODENKRAFT PLUS water storage pellets to my soil?
Answer: That depends on the specific conditions of your soil. However, you should generally consider adding the pellets once per season or as needed to optimize moisture and nutrient retention. I also add them directly to the pots during dry periods, when I notice that the natural water isn't enough or the soil can no longer retain enough water. I do this quite unorthodoxly by making a hole, rattling the pellets into it, and soaking them with water.
5. Question: Can BODENKRAFT PLUS water storage pellets help save water?
Answer: Yes, thanks to their high water-holding capacity, the pellets can help keep the soil moist longer, meaning you'll need to water less frequently. This can be especially useful in dry areas or during periods of water scarcity. I also think it feels good to be mindful of the water resource.
6. Question: In what containers are these water storage pellets available?
Answer: For the vegetable and flower garden, we chose a bucket that's easy to place in the garden and can be easily resealed. Especially for us, one that can be left standing. I notice again and again that we want to use these products, BUT, if they're not readily available, then they just don't. Therefore, we place the bucket where we'll need it again and again. Please reuse the empty bucket as a harvest bucket, mixing bucket, etc. It holds 6 kg. I would work this into a 2 m² raised bed.
For agriculture, we have 1000kg big bags . This is enough for 3 hectares. In very dry areas, it's enough for 2 hectares. We also pack the pellets in 10kg bags . Bags are sometimes easier to process and transport to the places where they're needed.
When should the pellets be added to the soil?
BODENKRAFT PLUS water storage pellets can be incorporated into the soil at any time of the year. However, there are some optimal times that are particularly suitable because you'll be working with the soil anyway:
-
Spring: This is often the best time to add pellets to the soil, especially if you plan to plant new plants or sow seeds. The pellets can help prepare the soil for planting and ensure that the young plants and seedlings have a consistent water supply.
- Fall: The pellets can also be incorporated in the fall, especially when preparing the soil for the next planting season. They help retain water and nutrients and can help keep the soil in good condition during the winter months.
The pellets should be mixed into the top 15-20 cm of soil, as this is where most plant roots absorb their nutrients. You can simply mix them into the existing soil before planting, or work them around existing plants and then water thoroughly to activate them.
How can I store water in the soil?
Application examples
We hear this question again and again. Usually, of course, when we're directly affected by drought. And when it rains, some soils can't hold the water, and it runs through.
BODENKRAFT PLUS water storage pellets are versatile and can be used in a range of applications to improve moisture and nutrient retention.
Here are some possible use cases:
1. Home gardens: Whether you grow vegetables, fruit trees, flowers, or ornamental plants, these pellets can help improve soil moisture and nutrient levels, increasing plant health and productivity.
2. Commercial agriculture: On agricultural land, the pellets can help improve water use efficiency and nutrient availability, which can lead to higher yields.
3. Reforestation and landscaping: When used in reforestation or landscaping, the pellets can help improve the survival rate and growth of newly planted trees and shrubs.
4. Lawn care: They can also be applied to lawns to improve water retention and improve the health and appearance of the lawn.
In regions affected by droughts, soils can often dry out quickly and lose their ability to provide sufficient moisture for plants. This can be particularly problematic in soils that naturally have little water retention capacity, such as sandy soils or soils with high drainage capacity.
The use of BODENKRAFT PLUS water storage pellets in such soils can bring about a significant improvement. Their high water-holding capacity allows them to store water when it's available (for example, during a rainy period) and then gradually release it during a dry period. This can help provide plants with sufficient moisture even during dry periods, thus ensuring their survival and growth. And plants experience less drought stress.
In addition, the pellets can help improve the nutrient content of these soils. They store nutrients and release them gradually, helping to ensure a nutrient supply to plants even during dry periods. This can be especially important in soils that are naturally nutrient-poor or where nutrients are easily leached due to rapid drying.
BODENKRAFT PLUS water-storage pellets can also be extremely useful in troughs, tubs, window boxes, and other containers used on patios and balconies . These types of containers tend to dry out more quickly than gardens or larger landscaped areas, especially in hot or windy conditions, requiring frequent watering.
Of course, this also applies to indoor plants . If you underestimate watering, occasionally travel quickly, and want to do something good for your potted plant soil, then they're the right choice.
