For some, gardening is a simple pleasure that they put minimal effort into. For others, it is a much more involved hobby that brings them joy and satisfaction. However, whichever end of the spectrum you may fall on, there is more to successful gardening than meets the eye.

While minimal effort might produce some immediate satisfactory results, it is not sustainable over time. To maintain a garden year after year and see it flourish, you’ve got to put back into the soil what is taken out of it. Essentially, you’ve got to use a bit of science—geology, to be exact.

 Geology is the study of the earth and what it is made up of, including rocks and minerals, and minerals play an essential role in gardening. On a larger scale, the agriculture industry has been using geological applications in farming for years to keep soil and crops healthy. But even everyday gardeners can have more success if they use these same applications.

Soil is More Than Dirt

When you are gardening, everything essentially boils down to the soil. Watering and sunlight, of course, play a crucial role as well, but it is the soil that is the foundation of your garden and will ultimately determine how much success you have.

 While most people think of soil as the dirt in the ground, it is actually a complex mixture of minerals and organic matter. The soil that exists all around the earth is essential to our existence as it plays a key role in sustaining plant growth. The minerals and matter found in the soil can vary from one region to the next, and they ultimately determine what plants can grow there and which ones can’t.

 Soil formation occurs through a series of processes that takes place just below the Earth’s surface:

  1. Weathering produces loose debris, new minerals, and ions.
  2. Rainwater percolates through the debris and carries minerals and ions down into the ground. New minerals form further down in the ground as a result of the water mixing with the debris.
  3. Microbes, fungi, plants, and animals contribute to the process by absorbing nutrients and leaving behind organic waste and remains. Plant roots and burrowing animals churn and break up the sediment, and microbes metabolize minerals and organic matter, releasing chemicals into the soil. 

These processes all occur at different depths in the ground, which results in what is known as soil zones. These zones, also known as horizons, are arranged in a vertical sequence and make up the soil profile. The geological makeup of a soil, or its profile, will then determine what plant life can grow there.

Choosing the Right Soil For Your Garden

While some plants can adapt to the soil they are planted in, they will be stronger and healthier if they have the proper nutrients. So, it’s important to ensure your soil profile is healthy and has the right minerals your plants need to sustain your garden. Though the specific soil and minerals you need will vary depending on your region and the plants you wish to grow, all plants require 17 elements to complete their life cycle.

 Aside from Carbon, Hydrogen, and Oxygen, all of which are obtained from air and water, plants can get the remaining elements they need from fertilizers, manures, and amendments added to the soil. The soil itself, without any additions, should also have a good combination of minerals. If it doesn’t, you will need to add them in.

Using Minerals to Enhance Your Soil

To determine which minerals you need to use to enhance your soil, you will need to run a test. While there are at-home test kits available, the better option is to search your local area for companies that provide testing services. They will give you a more accurate result of the deficiencies in your soil.

 Some common minerals that you can use to address deficiencies in your soil include:

     Limestone

     Sulfur

     Mineral N-P-K (Nitrogen, phosphorus, and potassium)

Harmful Substances to Avoid

Vermiculite, a puffy, lightweight granule that some use to improve aeration in their soil, can sometimes contain cancer-causing asbestos. Vermiculite is a naturally occurring mineral that, on its own, is harmless, but before the 1990s, it was mined from the same ore deposits that contained asbestos mineral fibers. While modern products that contain vermiculite have high safety standards and should be asbestos-free, you should avoid old or imported vermiculite soil amendments.

Using Rocks to Add Depth to Your Garden

For many, having a garden is like having their own peaceful retreat in their backyard. However, building that retreat can take some time and effort. If you are looking to create a flourishing and sustainable garden, it’s important to do some research and use the applications above to ensure you have healthy soil.

If science isn’t your thing, you can still create a natural escape using rocks. Rock gardens are a great way to add depth and dimension without putting in much effort. You can certainly create an elaborate design using rocks and plants, but if you are looking for something that is easier to maintain and requires minimal effort, a simple rock garden is a way to go. There is no need to test and amend your soil, simply plan out your design, dig out the space, and lay the rocks down.

Wrapping Up

Though an understanding of geology is not necessary to plant a garden, it is highly beneficial for those looking to create something more sustainable that will last for years to come. Doing a bit of research and studying can go a long way towards creating a healthier and flourishing garden. Furthermore, the healthier our soil and plants are, the healthier our planet will be as a whole.

How to get kids interested in Geology

It is unfortunate that geology has such a dry reputation. We know that it’s more than just studying rocks and minerals. It’s about exploring the rich history of our planet’s formation and evolution, using the landscape as artifacts that have recorded the stories of every subtle tectonic shift, and each extinction event. Yes, there is work and fine diligence involved, but this is in the service of engaging with a fascinating subject.

However, it can often be difficult to get kids over that reputation and on the path to amazing discoveries. This is a shame because as a parent, you naturally want your child to be introduced to these kinds of ideas and activities that can ignite their imagination for years to come. For geologists, you want to share an educational experience that could intrigue students, and perhaps start them on their own road to studying the subject at university or just taking it up as a hobby. In either case, one of the primary hurdles is getting kids interested in geology in the first place.  

So how can you best go about doing this? How do you break through the stereotypes to give kids that spark of interest that can tempt them down the rabbit hole into the fascinating world of geology? Let’s take a closer look.

Go Multimedia

We can all agree that books are awesome, beautiful, essential items. However, you can’t just expect the wonders of geology to take hold of all kids by throwing an academic text at them. Remember that everybody engages in learning from a subjective perspective. Various educational theories explore the best ways to educate children, and many of them accept that effective learning can be dependent upon the student’s experiences, environment, and external influences. Connectivism, in particular, posits that children learn by forming strong connections to ideas, and this can be most effective when applied to things that excite them. Therefore, it can be important to take a multimedia approach that provides opportunities for kids to connect to geology in ways that are most relevant to them.

This could include:

     Documentaries

Introduce kids to documentaries about geology. But be sure to keep these viewings short. Utilize it as a way to get them intrigued or excited about a concept, and then follow it up with a more practical demonstration. Don’t just stick to films aimed at kids, though. The BBC’s Rise of the Continents (2013) series, for instance, is still an educational and entertaining look at how ancient geology connects to our modern lives without talking down to its audience.

     Hands-On Lessons

Often, geology is best explored through the physical evidence of its impact. Provide kids with physical examples of interesting geological phenomena — geodes, volcanic rock, fossils. Take them on field trips to caves to reach out and touch stalactites and stalagmites. If you can encourage them to have a hands-on experience of geology, you can spark their interest in how the world was formed and spur them to explore the subject further. Even better, if you can introduce them to geological features in their local areas such as waterfalls, mountains, and cave systems, they can form a more personal and relevant relationship with it.

Gamify Activities

Getting kids interested in geology can’t just be predicated on passing on information. They need to be able to engage with it in fun and active ways. Whether as a parent or educator, you should be feeding their curiosity rather than trying to wrangle them into a lesson. One of the best ways to do this is by providing activities that are framed as games.

Some activities to consider are:

     Geocaching

One of the most fun aspects of geology is the potential for exploration. Geocaching gives kids the opportunity to head out on an adventure, explore the geological landscape of the area, and participate in a form of a treasure hunt. GPS coordinates provide your kids with the general location of a hidden container, and they have to explore the area to find it and enter their name in the logbook. These spots are hidden all over the world, and you can set your kids the challenge of making observations about the geological elements they notice along the way, you can even set geocache location clues based on natural landmarks. EarthCaching, a subset of geocaching spearheaded by the Geological Society of America, is also growing in popularity, and the cache includes educational information about the local landscape. 

     Minecraft

Believe it or not, Minecraft can be a good tool to get kids more engaged with geology. There are elements of volcanic activity, mineral identification, and earth development that reflect real-life geological behavior. Educators can use this as a forum through which to discuss geosciences. Set challenges for kids in the game to set about mining a certain amount and type of minerals, or to create a realistic volcanic eruption and lava flow, then talk about how this is reflected in real life. It can also be helpful to show them examples of the raw materials they use in the game — obsidian, redstone, quartz — and discuss how they’re formed.

Inspire Them

Passion can be contagious. As such, one way that you can be effective in getting kids interested in geology is by introducing them to people who not just have a passion for it, but are also talented in communicating and sharing that passion. Thankfully, our digital age provides great opportunities to find science communicators on YouTube or social media — the Smithsonian museum has posted talks with their geologist Dr. Ben Andrews, and astrobiologist Tara Djokovic has produced a TED talk on her research into how ancient rock can hold clues about the origins of life on our planet. Explore streaming services and social media to find the professionals that can inspire your kids to discover more.

Conclusion

Geology is an important field and one that has some fascinating elements. Getting kids interested in geosciences is often about finding ways to immediately help them to forge connections, and demonstrate that they can have fun while exploring the theory. Keep in mind that there are multimedia tools at your disposal, and introduce them to people and ideas that can spark their curiosity.
