Dig Deep and Celebrate World Soil Day

Greetings gardeners! World Soil Day is coming up on December 5th, and it's a great opportunity to dig deeper into the importance of soil in our gardens and beyond. Whether you’re a seasoned pro or novice gardener, understanding the essence of soil can transform your gardening experience.

Established by the Food and Agriculture Organization (FAO) of the United Nations, World Soil Day was created to raise awareness about soil health and sustainability. This is a day for us to reflect on the essential role of soil for food production, our ecosystems and gardens.

Foundation for Growth 

Our soil is a living ecosystem - supporting the growth of plants, animals, and microorganisms. It’s the unsung hero in our gardens, and the very foundation supporting all plant life, providing the essential nutrients and structure that enables our vegetables, flowers and trees to flourish. While we often take it for granted, how often do we really stop to consider the incredible complexity of soil?  

Microbes and Nutrient Supply

Essential nutrients like phosphorus, nitrogen and potassium are abundant in healthy soil, while they are also vital for plant growth. Nutrient levels can be further enhanced with the addition of organic matter, which helps retain moisture as well. Some ways to boost organic content include using well-rotted manure or composting. 

Aside from composting kitchen scraps, make sure you’re also encouraging the growth of microbes in your soil. They help speed up the breakdown of organic matter, providing nutrients to plants and keeping diseases at bay. Fostering microbial diversity is essential for thriving gardens, and practices like crop rotation can enhance your soil and ecosystem significantly. 

 

Water Retention

Water retention will also improve with good soil structure. Sandy soils that lack moisture drain quickly but dries out quickly, while clay soils may have too much water. So it’s best to aim for a balanced mix for best of both worlds. Consider incorporating organic matter like compost to enhance your soil's ability to retain moisture, making it easier for your plants to grow even during dry seasons.

Maintaining Soil pH

Another key factor for soil maintenance is Soil pH, which affects nutrient availability. The ideal pH for most garden plants is between 6.0 and 7.5, while testing your soil can help you understand its pH level and make adjustments if needed accordingly to boost plant growth. 

Using soil testing kits will give you additional insight into your soil’s nutrient content and pH, helping you tailor your gardening routine for better harvests.

Avoid Compacting Soil 

Try to avoid walking on your soil or garden beds, as foot traffic or heavy equipment can compact soil, thereby reducing its ability to drain and aerate. Consider using raised beds or adding pathways to protect soil health.

Plant a Cover Crop

During off seasons, consider planting cover crops like rye or clover in your garden. Aside from helping to prevent soil erosion, these plants also improve soil structure and fertility when turned back into the soil.

Share Your Knowledge

Now you know the importance of soil health, it’s time to share this knowledge with your fellow gardeners! You can pass on these handy tips in community gardens, local workshops, and even social media to spread the word, leading to healthier gardens in your community. 

More than just a date on the calendar; World Soil Day reminds us of the crucial role that soil plays in our gardens and for the environment. By nurturing our soil, we can create thriving gardens that not only we can enjoy, but also contribute to a healthier planet for all.
