What is Healthy Soil?
Healthy soil is the foundation of a thriving garden ecosystem. It’s a dynamic, living entity teeming with a diverse community of microorganisms, earthworms, and beneficial insects. Soils are home to 25% of the earth’s biodiversity! Building healthy soil is a fundamental aspect of regenerative gardening.
Healthy soil is well-structured, with a balance that allows for good drainage and aeration while retaining essential moisture and nutrients. It has a balanced pH level and is rich in organic matter, which provides a steady supply of nutrients to plants.
Building healthy soil is a process that takes time and continued nurture from the gardener. We only have to observe how Mother Nature builds healthy soil in the forest to understand the process. We can build our garden soil so that it not only supports plant growth but also fosters disease resistance and reduces the need for synthetic fertilizers.
In turn, healthy plants are more resistant to pest pressure. This reduces the need for pesticides, allowing gardeners to explore organic pest control in their gardens. It’s the key to garden productivity, and sustainable gardening practices.
Understanding Key Elements of Soil pH
An important factor in building healthy soil is understanding soil pH. pH is a measure of how acidic or alkaline the soil is. It is measured on a scale from 0 to 14, with 7 being neutral. A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity.
So why is soil pH important? Different plants have different pH preferences. Some plants thrive in acidic soil, like blueberries, while others (most) prefer alkaline conditions. If the pH of your soil is not suitable for the plants you want to grow, it can affect their ability to take up nutrients and ultimately impact their growth and productivity. Testing your garden soil pH is one of the first steps to take when you start a garden. Knowing that state of your soil at the start will help your efforts in building healthy soil.
To determine the pH of your soil, you can use a simple soil testing kit you can get at most gardening stores, or send a sample to a soil testing laboratory for a more detailed analysis. The University of Maryland Extension has a helpful article on soil testing and list of labs. Once you know the pH of your soil, you can take steps to adjust it if necessary. If your soil is too acidic, you can add lime or wood ashes to raise the pH. If it’s too alkaline, you can incorporate organic matter like peat moss or compost to lower the pH.
Building Healthy Soil Through Composting
Composting is a natural process that involves the decomposition of organic materials like kitchen scraps, yard waste, and even certain types of manure. When these materials break down, they release essential nutrients like nitrogen, phosphorus, and potassium, which are necessary for plant growth.
Additionally, composting adds organic matter to your soil, improving its structure and overall health. The organic matter in compost also serves as food for beneficial soil organisms, contributing to a well-balanced and productive ecosystem.
There are several methods of composting, from the traditional compost systems you can set up in your yard, to trench composting, to composting inside your house with methods like “Bokashi”. Different systems range from complex to simple. The time it takes can range from less than a month, to an entire year. The techniques may vary, but the process is the same: organic materials break down into rich, healthy soil.
Traditional Composting
As you get started in composting, it helps to have an understanding of the general process that most people use and are familiar with. To start composting, you’ll need a designated area in your garden or a compost bin. Begin by collecting kitchen waste like fruit and vegetable peels, coffee grounds, and eggshells. Chop these scraps into smaller pieces to speed up the decomposition process. You can also include yard waste like leaves, grass clippings, and twigs, as well as non-greasy food scraps.
Layering your compost pile is key to achieving a balanced mixture. Start with a layer of yard waste, followed by a layer of kitchen scraps, and then alternate between the two. You layer green (nitrogen-rich) and brown (carbon-rich) materials. It doesn’t have to be complicated. It also helps to add a layer of soil or finished compost now and then to introduce beneficial microorganisms to jumpstart the decomposition process. Make sure to keep your compost moist but not saturated, as a proper balance of moisture is essential for decomposition.
Regularly turning your compost pile with a pitchfork or shovel will help speed up the decomposition process and prevent any unwanted odors. The microorganisms responsible for breaking down the organic matter thrive in an aerated environment. Aim to turn your compost pile every two weeks, mixing the outer materials to the center and vice versa.
As your compost matures, it will transform into a dark, crumbly substance that resembles rich soil. This is a sign that it’s ready to be added into your garden beds or used as a top dressing for existing plants. The time it takes to mature varies. Simply spread the compost evenly over the soil surface and gently work it in using a garden fork or rake.
Innovative Composting Methods
Like I mentioned above, there are several methods of composting that have been developed for use. Many garden enthusiasts either don’t have the room or time for traditional composting, or they have discovered other methods they like better. For instance, I have room for traditional composting on my acre, but I prefer trench other methods. I also buy compost by the cubic yard because I can’t make enough myself to satisfy my garden dreams.
While this isn’t a tutorial on composting, it is worth mentioning some of the other methods:
- Vermicomposting: Vermicomposting uses worms to break down organic matter. It’s a space-efficient and odorless method suitable for small spaces.
- Bokashi Composting: Bokashi is an anaerobic composting method that uses a special bran inoculated with beneficial microbes. It’s ideal for composting kitchen scraps and can be done indoors.
- Trench Composting: This involves digging trenches in your garden and burying organic matter directly in the ground. It enriches the soil as it decomposes. (As a self-proclaimed “lazy gardener” this is my go-to method!)
- Compost Tea: Compost tea is a liquid fertilizer created by steeping compost in water. It can be used as a foliar spray or in a watering can.
- Lasagna Gardening: Layering organic materials directly on the garden bed to create fertile soil over time. It’s an excellent no-dig method to prepare new garden beds.
- Sheet Mulching: Sheet mulching is similar to the Lasagna concept, just simpler. You lay cardboard or newspaper over the soil, add a layer of compost or garden soil and then top with a mulch of wood chips or straw. This is my favorite method to use overwinter.
- Tumbling Composters: These are rotating bins that make turning and aerating the compost easier. They’re suitable for smaller spaces and can speed up the composting process.
- Community Composting: Joining or starting a community composting initiative where neighbors or a local organization collect organic waste for composting.
- Leaf Mulch: Leaves make a rich addition to your garden soil. There are several methods of making leaf mulch. The best thing about leaves is they are usually free and in abundance in the fall.
Each method has its advantages and may suit different gardening situations. And, don’t forget that you can buy compost. If you do, make sure to ask around and get references from other gardeners in your area. You want to avoid the inferior products, or worse, tainted compost, and get a quality compost.
Mulching Techniques for Garden Soil
Mulching is a practice that involves covering the soil surface with a layer of organic or inorganic material. This protective layer serves various purposes, all of which contribute to the overall health of your garden soil. As with composting, there are several ways to mulch, so you have choices.
As to our purpose of building healthy soil, mulching contributes to the overall fertility of your garden soil. Organic mulches, such as compost, shredded leaves, or straw, gradually break down over time, releasing nutrients into the soil. This natural fertilization process enriches the soil with essential elements, promoting healthy plant growth.
Additionally, as the organic mulch decomposes, it improves the soil structure by increasing its organic matter content. This results in improved water drainage, aeration, and nutrient availability for your plants.
One of the other benefits of mulching is moisture retention. By acting as a barrier, mulch helps to reduce evaporation, preventing water loss from the soil. This is particularly important in hot and dry climates where water scarcity is a concern. Additionally, mulch acts as a buffer against extreme temperature fluctuations, keeping the soil cooler during hot summer months and warmer during chilly winters.
Benefits of Using Cover Crops
Cover crops are yet another element that contributes to healthy soil. These are crops that are grown specifically to benefit the soil rather than for harvest. Cover crops help prevent soil erosion, suppress weeds, increase organic matter, and improve soil structure.
Popular cover crops, such as legumes or grasses, have deep roots that help break up compacted soil and increase its aeration. As these plants grow, they capture nitrogen from the atmosphere and fix it in the soil, replenishing this vital nutrient. Cover crops also provide organic matter when they are tilled back into the soil, further enriching its fertility.
Organic Soil Enrichment
One effective method for promoting plant growth is through the use of organic fertilizers. These natural substances provide essential nutrients that plants need for healthy development. Organic fertilizers, such as well-rotted manure or bone meal, release nutrients slowly over time, ensuring a steady supply of nourishment for your plants. In addition to providing essential nutrients, organic fertilizers also contribute to the overall health of the soil by improving its structure and increasing its ability to retain moisture.
Also, the addition of natural minerals and rock dust can play a crucial role in organic soil enrichment. Minerals like limestone, rock phosphate, and greensand provide trace elements and minerals that are essential for plant growth. These minerals help balance soil pH, improve nutrient availability, and support optimal plant development. By incorporating these natural minerals into your garden soil, you’re providing your plants with the necessary building blocks for vigorous growth and overall health.
Building healthy soil is a key way to implement permaculture practices into your backyard garden. One practice is a clever method of adding organic matter to the soil known as “chop and drop”, which is just what it sounds like. Chop up some leaves of nutrient-rich plants and drop them onto the garden to decompose. For example, plants with deep taproots, like comfrey, reach down below the topsoil and mine the minerals and nutrients not found in the topsoil. As they decompose, they bring all that richness to the topsoil.
