Using Compost Extracts for Improved Soil Health and Plant Growth

Composting is a crucial part of gardening and plant growth.

One of the keys to successful composting is being able to extract and use the microbes that develop during the process.

Enter compost extracts – a potent way to leverage the soil-borne bacterial and fungi in compost.

In this blog post, I will introduce compost extracts and how they relate to soil health and plant growth.

By the end of the post, you will have the information needed to make and apply your own compost extracts.

So, let’s dig in!

Benefits of Compost Extracts

Compost extracts benefit plants in several ways. They can provide a nutrient-rich solution that can be absorbed through the plant’s roots. Additionally, they can stimulate soil microbial activity, which can impact plant growth. Finally, compost extracts can help reduce soil-borne disease, which can protect the health of plants.

By using compost extracts, you can naturally fertilize your plants without using chemical fertilizers that can be harmful to the environment and to your own health. Compost extracts are especially beneficial for vegetable and fruit gardens, which require high levels of nutrients to produce healthy crops.

Increased soil microbial activity is another advantage of using compost extracts. Soil microbes are crucial for plant growth and can help make nutrients more accessible to plants. By adding compost extracts to your soil, you can increase the number of beneficial microbes, which in turn can improve soil fertility over time.

Reducing soil-borne disease is yet another way compost extracts can help your plants thrive. Soil-borne diseases can be difficult to control in the garden, but applying compost extracts can help manage these problems. The solution contains beneficial microbes and other compounds that can help suppress soil pathogens.

Overall, using compost extracts can improve the health and growth of your plants. By providing nutrients, stimulating soil microbes, and reducing soil-borne disease, compost extracts offer numerous benefits for gardeners.

How to Make Compost Extracts

Compost extracts, also known as compost tea, are a cost-effective way to improve soil health and support plant growth. Making a compost extract is fairly simple and requires only a few materials.

To make a compost extract, you will need:

• Compost: You can use any type of compost, as long as it is well-aged and does not contain any plant or weed seeds.
• Water: Use non-chlorinated water, as chlorine can kill beneficial microorganisms in the compost.
• Aeration source: An air pump or an aquarium aerator can be used to maintain continuous oxygenation.

The steps to make a compost extract are as follows:

1. Fill a bucket with water and add compost at a ratio of one pound of compost per gallon of water. Use a mesh bag or pantyhose to hold the compost and avoid messy clean-up.
2. Let the mixture sit for 24-48 hours to allow beneficial microorganisms to multiply.
3. Add an aeration source to the bucket and maintain circulation for at least 12 hours.

The optimal extraction time for compost tea is 24-48 hours. However, it is recommended to not exceed 72 hours to avoid the multiplication of unwanted pathogens.

When extracting compost tea, it is important to keep in mind that the nutrient content can vary depending on the type of compost used and the extraction time.

For optimal results, you may add other organic ingredients such as molasses or kelp meal to the mix. These ingredients can increase the microorganism population and, as a result, enhance the nutrient content of the compost extract.

Making a compost extract is a simple and affordable process that can greatly benefit your soil health and enhance the quality of your plants. By following these tips, you can optimize your compost extract to ensure the best possible results.

When to Apply Compost Extracts

To ensure optimal benefits, compost extracts should be applied at the right time. The best time to apply compost extracts is during the growing season, when plants are actively growing and require more nutrients. Applying compost extracts too early or too late in the season may not give the desired results.

Seasonal considerations also play a factor in determining the timing of compost extract application. For example, fall and winter applications of compost extracts are ideal for perennial plants going into dormancy. Springtime, on the other hand, is a great time to apply compost extracts to give plants a healthy start for the growing season.

For annual plants, applying compost extracts every 2-3 weeks during their growing season can help maintain nutrients in the soil. It is essential to monitor the condition of the plants because, if the plants appear to be struggling, it may be necessary to increase the frequency of application.

By observing the growth patterns of your plants, you can better determine when to apply compost extracts to achieve maximum benefits. Additionally, when applying compost extracts in conjunction with a scheduled watering routine, it can help ensure consistent nutrient levels for the plants.

Techniques for Applying Compost Extracts

If you want to apply compost extracts to your garden, there are different techniques you can use to maximize their benefits. Each technique has its advantages and disadvantages and is suitable for different types of plants.

Soil Drenching

Soil drenching involves mixing a concentrated compost extract with water and applying it directly to the soil around the plant’s root zone. This technique helps improve soil structure, promote root growth, and increase nutrient uptake by plants. It is best for established plants and is usually done at the beginning of the growing season.

Foliar Spraying

Foliar spraying involves spraying the diluted compost extract directly onto the leaves of a plant. This technique enhances the plant’s natural pest and disease resistance and can provide a quick nutrient boost to the plant. However, it is not suitable for all plants, and it should not be done during the hottest part of the day, as it can scorch the leaves.

Seed Coating

Seed coating is a technique where the seeds are coated with a mixture of compost extract and water. This technique can promote faster germination, increased root growth, and faster establishment of the plant. It is best suited for small seeds and is done before planting.

When you choose a technique to use, it is essential to follow the application instructions carefully and avoid overuse. Always start with a small amount of extract and gradually increase the frequency and amount until you notice the benefits.

In the next section, I will discuss commercially available compost extracts and what you should know before purchasing them.

Commercial Compost Extracts

If you’re looking to use compost extracts but don’t have the time to make them yourself, commercial extracts are another option. These products are widely available and come in various forms, including liquids, powders, and granules. However, it’s essential to understand that not all products are created equal. When choosing commercial compost extracts, be sure to read the label carefully. ### Choose products that are organic and have a varied microbial profile.### Make sure the brand undergoes third-party testing to verify the quality of the extract. Some of the most popular commercial compost extracts include Dr. Earth and Nature’s Lawn Soil Activator.### While commercial extracts can be convenient, they don’t offer quite the same benefits as DIY compost extracts. Also, they’re usually more expensive, so keep that in mind when deciding which option to choose. Finally, commercial compost extracts are not as fun to make as DIY ones are - but that’s probably just my opinion.
