What is Vermiculite and how does it store water in the soil?
Vermiculite is a naturally occurring mineral belonging to the group of phyllosilicates. It has the remarkable property of significantly expanding its physical structure when exposed to high temperatures, a process known as "exfoliation" or "popping." During this process, vermiculite occupies many times its original volume and takes on a structured, porous form, allowing it to store 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 various ways to improve plant health and growth:
1. Water storage: Due to its porous structure, vermiculite can store 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 essential for plants such as potassium, calcium, and magnesium. These nutrients are then gradually released to the plants, helping to ensure a steady supply of nutrients.
3. Improvement of soil structure: Vermiculite can help improve the structure of the soil. It helps loosen the soil and improve aeration, which promotes root growth and prevents waterlogging.
4. pH neutrality: Vermiculite is pH-neutral, meaning it does not affect the acidity of the soil. This is important as many plants are sensitive to changes in pH.
Overall, vermiculite can 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 have 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 also well-known mineral mica.
The chemical formula of vermiculite is (Mg,Fe,Al)3(Al,Si)4O10(OH)2·4H2O. This shows 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 drought 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 reservoirs.
Here are some of the benefits these water storage pellets offer due to their specific properties:
1. Moisture retention: The ability of vermiculite and zeolite to store water is remarkable. They can absorb and store up to 50 times their weight in water. This moisture is then gradually released to the plants as needed. This can be particularly useful during periods of irregular rainfall or in dry areas to ensure plants always have access to water. This reduces the need for regular watering and minimizes water waste.
2. Nutrient storage and supply: In addition to their ability to store water, these pellets are rich in minerals and trace elements. They can absorb and store nutrients, then gradually release them over a longer period.
This improves soil fertility and allows for optimal nutrient absorption by the plants, which helps to reduce the use of fertilizer and naturally leads to more vigorous plant development.
3. Soil improvement: Vermiculite and zeolite help improve the structure of the soil. 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 in the soil, leading to healthier, stronger plants.
4. Temperature control: Due to their heat-insulating properties, the pellets help protect the soil from extreme temperature fluctuations. They prevent rapid cooling of the soil, which can be particularly useful in cold climates. Especially when cucumbers and tomatoes are planted, the soil can sometimes still cool down considerably, and then the pellets are very helpful in providing the sensitive young plants with a uniform soil temperature.
5. pH neutrality: Vermiculite and zeolite are almost pH-neutral, which means they do not affect the pH of the soil. This is important because the pH of the soil can affect the availability of certain nutrients for plants. You have already read this above.
BODENKRAFT PLUS Water Storage Pellets are therefore a valuable aid for anyone who wants 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: As a rule, 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 there encourage the fine roots to connect well with the soil.
2. Question: Can I also use the BODENKRAFT PLUS Water Storage Pellets in my indoor plants?
Answer: Yes, the pellets can be safely used indoors. They can help retain moisture in the soil and optimize nutrient supply for your houseplants. Especially potted plant soil can benefit from a little boost, and if you forget to water once, it's not such a big crisis.
3. Question: Are the BODENKRAFT PLUS Water Storage Pellets safe for all plant types?
Answer: Yes, the pellets are suitable for all plant types. They are made from natural minerals and contain no harmful chemicals that could negatively affect plant growth. No binders either. They are also vegan, which I appreciate in my vegetable soil. I don't want anything from dead animals in my vegetable soil, or even with my plants and flowers.
4. Question: How often do I have to add the BODENKRAFT PLUS Water Storage Pellets to my soil?
Answer: This depends on the specific conditions of your soil. As a rule, however, you should consider adding the pellets once per season or as needed to optimize moisture and nutrient storage. I also add them directly to the pots during dry periods if I notice that the natural water is not enough, or the soil can no longer store enough. I do this quite unconventionally by making a hole, letting the pellets fall in, and soaking them with water.
5. Question: Can the BODENKRAFT PLUS Water Storage Pellets help save water?
Answer: Yes, due to their high water retention capacity, the pellets can help keep the soil moist for longer, meaning you need to water less frequently. This can be particularly useful in dry areas or during periods of water scarcity. I also find it gives a good feeling to be mindful of the resource of water.
6. Question: In which containers are these water storage pellets available?
Answer: For the vegetable and flower garden, we chose a bucket that can be easily placed in the garden and is well resealable. And above all, it can be left there. I keep noticing that we want to use these products, BUT if they are not readily available, then they are not used. Therefore, place the bucket right where you need it again and again. Please reuse the empty bucket as a harvest bucket, mixing bucket, etc. 6 kg fit in there. I would work that into a 2 m2 raised bed.
For agriculture, we then have 1000kg BigBags. That's enough for 3 hectares. For very dry areas, for 2 hectares.
When should the pellets be added to the soil?
The BODENKRAFT PLUS Water Storage Pellets can be incorporated into the soil at any time of the year. However, there are some optimal periods that are particularly suitable because you are already working with the soil:
-
Spring: This is often the best time to incorporate the pellets into 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 young plants and seedlings have a constant water supply.
- Autumn: The pellets can also be incorporated in autumn, especially if you are preparing the soil for the next planting season. They help store 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 the soil, as this is the area where most plant roots absorb their nutrients. You can simply mix them with the existing soil before planting, or incorporate 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 repeatedly, usually when we are directly affected by drought. And when it rains, some soils cannot retain the water, and it drains away.
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 applications:
1. Home gardens: Whether you grow vegetables, fruit trees, flowers, or ornamental plants, these pellets can help improve the moisture and nutrient balance of the soil, thereby increasing plant health and productivity.
2. Commercial agriculture: In agricultural areas, the pellets can help make water use more efficient and improve nutrient availability, which can lead to higher yields.
3. Reforestation and landscaping: 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 enhance the health and appearance of the lawn.
In regions affected by drought, 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 retain little water, 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. Due to their high water retention capacity, they can store water when it is available (for example, during a rainy period) and then gradually release this water during a dry period. This can help provide plants with sufficient moisture even during dry times, 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, which helps ensure the nutrient supply to plants even during dry times. This can be particularly important in soils that are naturally low in nutrients or where nutrients are easily leached out due to rapid drying.
BODENKRAFT PLUS Water Storage Pellets can also be extremely useful in planters, pots, flower boxes, and other containers used on terraces and balconies. These types of containers tend to dry out faster than gardens or larger landscape areas, especially in hot or windy conditions, requiring frequent watering.
Naturally also for indoor plants. If you underestimate watering, sometimes go away quickly, and want to do something good for your potted plant soil, then they are correctly used.
