You might have heard that produce in our grocery stores today contains 20% of the nutritional content it did just 50 years ago. Why do you think that is? Because contemporary methods of farming do not focus on soil health. Soil health is the only way to grow nutritious fruits and vegetables, and when done right, prevents pests and weeds.

The fact is, healthy, bountiful plants all start with soil health. In this article we discuss ways to improve your soil health which will in turn produce an abundant harvest.

Common Reasons Why People Experience Problems with Their Plants
Before we dive into how to improve your garden soil, it is important to understand the common reasons why people may experience problems with their plants, because any one of these will affect your soil and counteract the effort you are taking to make improvements:
  1. Improper Watering: Overwatering or underwatering can both be detrimental to plants. Overwatering can lead to root rot and other fungal diseases, while underwatering can result in wilting and nutrient deficiencies.
  2. Inadequate Sunlight: Plants have varying light requirements, and not providing them with the appropriate amount of sunlight can lead to stunted growth, poor flowering, and overall decline.
  3. Lack of Proper Nutrients: Plants require specific nutrients for healthy growth. Nutrient deficiencies or imbalances can result in yellowing leaves, poor flowering, and reduced vigor.
  4. Incorrect Planting Depth: Planting too shallow or too deep can stress plants. It’s important to follow recommended planting guidelines for each specific plant species.
  5. Lack of Mulching: Mulch helps retain soil moisture, suppress weeds, and regulate soil temperature. Not using mulch can lead to moisture fluctuations and weed competition.
  6. Inadequate Air Circulation: Poor air circulation around plants can create conditions conducive to fungal diseases and pests. This is especially important in preventing issues like mildew and mold.
  7. Inconsistent Maintenance: Regular maintenance, including pruning, deadheading, and removing diseased or damaged plant material, is essential for plant health.
  8. Improper Fertilizer Application: Over-fertilizing or using the wrong type of fertilizer can lead to nutrient imbalances, which can harm plants rather than help them.
It's important for gardeners to be attentive to and observant of their plants' needs. Regular monitoring, proper care, and timely intervention in response to any signs of stress or issues can go a long way in maintaining healthy and thriving plants.

Seeking out specific care instructions for each type of plant can make a significant difference in the plants’ overall well-being.

Soil Health: The Most Commonly Overlooked Issue Related to Plant Health
Soil health is the #1 reason why gardeners experience lackluster results. It’s common to assume that all soils are equal, when the fact is some soils on your land or in a bag that you purchase are not equipped to grow plants. 

The reality is that it is important to provide plants with the right type of soil and ensure it’s well-draining and rich in organic matter.

Any organic matter in the form of aged manure, compost, or cover crops will prepare the soil for planting. In addition, these methods loosen and lightens the soil while providing essential nutrients and enhancing your soil sulfur, giving you the best chance of success.

How to Improve the Health of Garden Soil
The success of your garden starts with your soil, here are some tips to help you improve the health of your garden soil:

  1. Conduct a Soil Test: Before making any amendments to your soil, it’s essential to know the current state of your soil. A soil test will provide information on pH levels, nutrient content, and any deficiencies that need to be addressed.
  2. Add Organic Matter: After you know the make-up of your soil, incorporate organic matter such as compost, well-rotted manure, or leaf mold. These enrich the soil with essential nutrients, improve drainage, and enhance its ability to hold moisture.
  3. Practice Crop Rotation:Rotating crops helps prevent soil depletion by varying the types of plants grown in a given area. Different plants have different nutrient requirements, so rotating them can maintain soil fertility.
  4. Mulch Regularly:Apply organic mulch like straw, wood chips, or shredded leaves to the surface of the soil. Mulch conserves moisture, suppresses weeds, regulates soil temperature, and gradually enriches the soil as it breaks down.
  5. Avoid Over-Tilling:Excessive tilling can disrupt the natural structure of the soil and lead to compaction. Use minimal tillage methods to preserve soil structure and encourage healthy microbial activity.
  6. Maintain Proper pH Levels:Adjusting the pH of your soil to match the needs of your plants is crucial. Most plants prefer slightly acidic to neutral soil (pH around 6–7).
  7. Provide Adequate Drainage:Ensure that your garden beds have proper drainage to prevent waterlogging. Amending heavy clay soils with organic matter can improve drainage, while adding grit to sandy soils can enhance water retention.
  8. Avoid Compaction:Minimize foot traffic and heavy machinery on garden beds to prevent soil compaction. Compacted soil limits root growth and reduces the exchange of air and water.
  9. Use Natural Amendments:Depending on your soil test results, consider using natural amendments like lime (to raise pH) or sulfur (to lower pH) to adjust soil conditions.
  10. Practice No-Dig Gardening: No-dig gardening methods, like lasagna gardening or raised beds, can help preserve the structure of the soil and promote healthy microbial life.
  11. Provide Adequate Aeration: Using tools like a garden fork or aerator, gently loosen compacted soil to improve air circulation and root penetration.

Remember that soil improvement is an ongoing process, and it may take time to see significant results. Regular observation of your plants and soil, along with thoughtful amendments, will lead to healthier and more productive gardens over time.

One Simple Way to Improve Soil Health: Cover Crops
One of the easiest ways to improve soil health that checks almost all of the boxes listed above is to incorporate cover crops. Planting cover crops like clover or rye during the off-season helps protect the soil from erosion, adds organic matter when turned under, and improves soil structure.

What Is a Cover Crop?
Cover crops have been in use for centuries. Gardeners typically plant them in the offseason and then harvest them before they plant the cash crop. They usually grow over the winter to manage soil quality, fertility, and erosion.

Soil erosion can be devastating for gardeners. It is the process by which the productive capacity of an ecosystem wears down. Cover crops slow down the rate at which rainfall connects with the soil’s surface, preventing runoff. It keeps the soil in place, so it is ready for the actual crop you want to harvest. In addition to preventing erosion, there are numerous other benefits to be gained by planting a cover crop before your cash crop.

What Are the Benefits of Cover Crops?
Cover crops can improve the overall structure of the soil. The roots of the crop allow the soil to avoid compaction, and they create pore spaces and passages when the roots take hold, which allows for moisture to build up. 

Cover crops are great for any organic matter because it stimulates the production of microorganisms. You can wait until the cover crop dies or use it as a form of compost to maintain healthy soil quality throughout the entire year.

Cover crops contribute to the biodiversity of your garden by attracting a wide variety of insects to your soil. When you attract insects to the site, you will inevitably attract some pollinators, and these bugs assist with the propagation of your garden plants. 

You may also benefit from your cover crop by using it as produce. Some common varieties of cover crops include legumes and mustard plants. When it comes time to harvest the plant, you can enjoy some tasty snacks right before you plant your cash crop.

Mulching and composting are hard work. You can save yourself a lot of time and energy by simply using a cover crop. It makes it an ideal choice when you have a large area where you need to improve the soil quality. 

Anyone wanting to know how to make the soil more alkaline can rest easy knowing cover crops add nitrogen to the soil, especially if you decide on using a legume for your cover crop. When the cover crop dies, the nitrogen remains in the soil for future plants to benefit from.

The reason why many gardeners refer to cover crops as living mulches is due to their ability to suppress weeds. The roots of your crops will compete with any weeds in the garden for essential nutrients. 

The cover crop usually wins out, and the weeds die when they are deprived of the materials they need to live. Additionally, the leaves of the crops cover the ground, preventing the weeds from performing photosynthesis. With so many advantages to cover crops, it is easy to see why gardeners have adopted them for centuries.

How to Choose a Fall Cover Crop
There are four variations of cover crops you need to consider. You can select non-legume broadleaves, brassicas, legumes, and grasses. Each one has its own benefits, and these are the most common varieties.

Barley is tolerant of saline and dry soils, and it can grow up to two to three feet in height.

Oats are tolerant of wet soil, and they create the least organic material out of all of the grasses. They can grow between two and three feet in height. However, you need to remember that oats generally succumb to the detrimental effects of winter.

Winter Rye
Winter rye is highly recommended for colder winter climates, and it is exceptionally tolerant of acidic soils. This plant can grow between four and five feet in height, and you can sow between two and three pounds for every 1,000 square feet of the plant.

Annual Ryegrass
You need to be careful with annual ryegrass because it can turn to weeds if you are not careful. The seeds are affordable, and it does well in tolerating flooding. It can grow between two and three feet in height.

Grasses are a popular choice of the cover crop because they grow quickly, improve the structure of heavily compacted soils, and tolerate the cold well. They do well in controlling erosion, which is great for wetter areas. You can mow or cut down the grass in the springtime before setting your other seeds.

Crimson Clover
Crimson clover can turn into an invasive weed if it goes to seed, so be careful. It grows up to 18 inches in height.

Berseem Clover
Berseem clover produces high quantities of nitrogen. It grows between one and two feet in height, and you can sow two pounds for every 1,000 square feet planted.

Field Pea
Field pea is a late-maturing and low-growing crop. It can grow to be several feet in height, although some varieties will only make it to six inches.

Hairy Vetch 
Hairy vetch is recommended when you already have poor soil, and it matures very late into the season. It grows to be two feet in height.

Hardy Legumes 

Hardy legumes are suggested when you need some nitrogen-fixing crops. Legumes typically do not mature until May, so you will need to cut them down before they go to flower.

You need to consider what soil and climate your crops will be in. It will allow you to select a cover crop best suited for your garden.

Why Fall Is a Good Time for Cover Crops

  1. Utilizes Empty Garden Beds: In many regions, fall is when summer crops are harvested, leaving empty garden beds. Planting cover crops at this time allows you to utilize the space that would otherwise be unused during the winter.
  2. Cooler Temperatures: Fall provides optimal conditions for cover crops to get established. Cooler temperatures and increased moisture create favorable growing conditions.
  3. Overwintering Benefits: Many cover crops are cold-tolerant and continue to grow slowly over the winter months. This provides additional soil protection and benefits even during the dormant season.
  4. Early Spring Benefits: Cover crops planted in the fall can be easily turned into the soil in early spring, providing a nutrient boost for your next planting season.
