Introduction

Soil health, also referred to as soil quality, is defined by its “fitness for use” (Larson and Pierce, 1991) and “the capacity to function within natural or managed ecosystems in a way that does the following: sustains plant and animal productivity, maintains or enhances water and air quality, and supports human health and habitation” (Karlen et al., 1997).

How to Maintain Healthy Soil

To maintain healthy soil, you first need to recognize it as a living ecosystem that needs care. Lyngso created a guide that covers essential steps to support soil structure, texture, pH levels, and biological activity for a thriving landscape.

Understanding the Key Functions of Healthy Soil

Healthy Soil Performs Five Vital Functions

  • Supports Plant Growth: Soil provides air circulation, retains water, and supplies nutrients. The right balance of sand, silt, and clay ensures optimal aeration and structure.
  • Hosts Beneficial Organisms: Bacteria, fungi, earthworms, and insects create a thriving ecosystem that enhances soil health.
  • Recycles Nutrients: Soil decomposes organic matter into humus, releasing essential nutrients for plant absorption.
  • Filters and Stores Water: Healthy Soil purifies rainwater, supports vegetation, and replenishes groundwater reserves.
  • Provides a Stable Foundation: Soil supports landscapes, buildings, roads, and plant root systems, maintaining structural integrity.

Soil Texture vs Soil Structure

Understanding the difference between soil texture and soil structure is crucial for soil health management:

  • Soil Texture refers to the proportion of sand, silt, and clay in your soil. Testing your soil helps determine the best way to modify texture by adding necessary amendments. Read more about what to consider when improving soil texture: Tips on Modifying Your California Soil with Amendments.
  • Soil Structure describes how soil particles cluster and form aggregates, influencing water infiltration, aeration, and root penetration. Watch How to Improve Your Soil for more on soil structure.

Testing Your Soil: A Vital Step for Improvement

Next, to fully understand what types of soil amendments, composts, fertilizers, and mulches your soil needs, you want to start by testing your California soil. This will reveal things like soil texture, pH, nutrients, and organic matter.

Before applying any amendments, fertilizers, or compost, it’s important to test your soil. This will help you identify factors like:

  • Nutrient levels
  • Organic matter content
  • pH balance
  • Texture and composition

Ideally, your soil should have characteristics that include:

  • Sufficient nutrient availability
  • High levels of decomposed organic matter
  • Optimized water retention and drainage
  • Low levels of harmful compounds
  • Strong structure for root penetration
  • A thriving population of beneficial microorganisms

How to Enrich Your Soil

Soil Amendments

Adding the right amendments, compost, and fertilizers can greatly enhance soil quality. Here’s how each contributes:

Soil amendments improve physical properties such as aeration, permeability, and moisture retention.

Some of the best soil amendments include:

Compost

Compost is decomposed organic matter rich in nutrients that enhance soil structure and moisture retention. Benefits include:

  • Improving sandy soils’ ability to hold water
  • Enhancing drainage in heavy clay soils
  • Boosting microbial activity that aids in nutrient breakdown

A top choice in California is Organic Green Waste Garden Compost which is particularly beneficial in coastal areas like the Bay Area. Read more in The Pros and Cons of Various Types of Compost As They Relate to Your Plant Growing Goals

Organic Fertilizers

Fertilizers address nutrient deficiencies, ensuring plants receive the necessary nitrogen (N), phosphorus (P), and potassium (K). Before applying fertilizers, always test soil pH levels to determine precise nutrient needs.

Compost Tea

Compost Tea is a liquid concentrate containing beneficial microbes that:

  • Enhance nutrient cycling
  • Improve soil structure and aeration
  • Degrade pollutants and balance soil pH

One excellent option for stimulating root growth and mitigating transplant shock is Bu’s Brew Dynamic Compost Tea. It has billions of microbes in addition to all of the major and minor nutrients and trace minerals.


Soil amendments, compost, and organic fertilizers all offer your soil varying components that it may need in order to reach its greatest potential. Learn more about what each provides so that you can determine which is best to use with your soil.

Protect Your Soil with Mulch

When thinking about protecting your soil, think mulch. Mulch refers to any ground cover that protects the soil. Organic and natural mulch helps with moisture retention, weed prevention, and water loss due to surface evaporation. Covering your landscape with at least 1″ of mulch helps provide the soil with much-needed protection from natural weathering elements. Plus, the mulch will decompose over time, providing carbon matter and feeding your soil.

Lyngso has several mulches to choose from so you can match your garden aesthetics while helping protect your soil. An attractive and popular example is Mini Mulch Fir Bark, which decomposes faster than larger mulch and turns into an organic soil amendment so you get the best of both worlds, protection and the improvement of your soil’s physical properties.
