Slash your soil costs: easy diy amendments you can find in your backyard

Tired of shelling out a fortune for perfectly amended soil? There’s a surprisingly simple, eco-friendly, and significantly cheaper solution hiding right under your nose: your own backyard.

Unlock healthy soil without breaking the bank

For years, gardeners, farmers, and permaculturists have relied on organic soil amendments to build a stronger foundation for their plants. Now, you can ditch the expensive deliveries and start nurturing your soil with readily available materials. It’s easier than you think, and it's a crucial step towards a thriving garden.

In my book, Garden Alchemy, I delve deep into the art of soil fertility, composting, and the diverse world of amendments. I even break down the N-P-K ratios of animal manure – a surprisingly complex topic, if you’re serious about soil health. But today, let’s focus on the quick wins: the amendments you can grab for free or at minimal cost.

I’ve partnered with Elizabeth Murphy, a soil scientist and author of Building Soil: A Down-to-Earth Approach, to bring you a curated list of backyard treasures. Elizabeth’s experience as an agricultural extension agent and researcher provides invaluable insights. Her words, excerpted from both our works, highlight the vital connection between healthy soil and flourishing plants.

Why feed your soil? it's more than just a foundation

Don’t be fooled into thinking soil is just dirt. It’s a bustling ecosystem teeming with life – a complex web of organisms that actively regulates itself, provided it receives the right nourishment. A simple soil composition test using a mason jar can reveal the percentages of sand, silt, and clay, giving you a clear picture of your soil’s primary makeup. But the real key is amendment – adding organic matter to balance out the composition and support this vital ecosystem.

Elizabeth stresses that the amount needed varies depending on whether you have sandy or clay soil, but a generous dose of amendments will invariably create a harmonious balance over time. The soil food web – a network of beneficial microbes – will consume what it needs and leave the rest, breaking it down and enriching the soil. It’s a remarkable process, a testament to the intricate beauty of nature.

5 Backyard amendments to supercharge your soil

Here are five common soil amendments you can find right in your backyard, ready to revitalize your garden:

1. Compost: the garden’s gold

Compost is undoubtedly garden gold. The decomposed organic material from your home compost pile is free, local, and packed with nutrients. My guide to composting offers a straightforward recipe, even for beginners. The trick is to maintain a balanced mix – addressing any unpleasant odors with a few simple adjustments. Remember, compost doesn’t replace fertilizers; it builds a stronger foundation for plant growth.

2. Manure: nutrient-rich power

Organic animal and mushroom manure can be a powerful amendment, but nutrient content varies greatly depending on the animal and the manure’s age. Fresh manure is richer than aged manure, but composting it first is essential to kill pathogens. Be cautious when using horse manure, as it can contain undigested herbicides that harm plants. Prioritize local, organic sources for the healthiest options.

3. Leaves: a forest’s gift

Let your leaves fall naturally! Instead of raking them away, I leave them in place, allowing them to decompose and enrich the soil below. This “forest floor” approach mimics nature’s recycling process. Shredding leaves before adding them to the soil improves their decomposition rate. Elizabeth recommends adding composted leaf mold to improve soil structure and fertility.

4. Green manures: plant power

Green manures – plants grown specifically to enrich the soil – are a fantastic tool. Red clover, buckwheat, and vetch are just a few options. Plant them in gaps between rows or in the fall to break up compacted soils and add nitrogen. Incorporate the green manure into the soil a few weeks before planting.

5. Other organic scraps: waste not, want not

Don’t toss those fallen plant clippings! Chop and drop composting – leaving plant material on the soil surface – creates a spongy, nutrient-rich mulch. Similarly, digging small holes and adding green scraps directly to the soil provides a localized boost of organic matter. Remember to avoid invasive plants and weeds.

Final thoughts: feed your soil, feed your garden

These backyard amendments offer a cost-effective and eco-friendly way to build healthy soil. Don’t limit yourself – explore the resources available in your community.
