5 Signs Your Soil Is Unhealthy (and What to Do About It)

Your soil is more than just dirt—it's the foundation of your entire garden or farm. When soil health declines, plants start to struggle. Unfortunately, unhealthy soil can be easy to overlook because the signs aren’t always obvious. Understanding what to watch for—and how to respond—can help you transform tired, compacted, or depleted soil into a thriving ecosystem. Here are five common signs your soil may be in trouble, and actionable steps you can take to improve it.

1. Compacted or Hard Soil

One of the most common issues in both gardens and fields is compacted soil. If your soil feels dense, hard to dig, or forms large clumps, it’s likely compacted. Compaction limits root penetration, reducing plant access to nutrients, water, and air. It also disrupts beneficial microbial communities. Over time, compacted soil creates an unhealthy growing environment that stunts plant growth.

What to do: Minimize traffic on wet soil, reduce tillage, add organic matter such as compost, fish fertilizer and activated biochar. Planting deep-rooted cover crops can also help break up compaction naturally.

2. Poor Drainage

Does water pool on the soil surface or run off too quickly? Poor drainage is another key sign of unhealthy soil. It often results from compacted layers or low organic matter content. Waterlogged soil suffocates plant roots, while overly fast-draining sandy soils leave roots parched and unable to absorb nutrients effectively.

What to do: Add organic material to improve water-holding capacity or permeability, depending on your soil type. For clay-heavy soils, organic matter loosens the structure; for sandy soils, it helps retain moisture.

3. Lack of Life

Healthy soil teems with life. If you rarely see earthworms, insects, or fungal networks in your soil, that’s a red flag. A lack of biological diversity means the soil food web is out of balance, which impacts nutrient cycling, disease suppression, and overall soil resilience.

What to do: Reduce or eliminate synthetic chemicals that harm microbes. Feed soil life with compost, cover crops, and bioactive amendments like Fishilizer, FiveChar, or WormCraft from SoilWorx.

4. Poor Plant Performance

If your plants show yellowing leaves, stunted growth, weak stems, or increased pest problems, the root cause may lie below ground. Unhealthy soil cannot supply adequate nutrients or foster strong root development. Over time, even disease-resistant plants become vulnerable.

What to do: Conduct a soil test to assess nutrient levels and imbalances. Rebuild soil fertility with organic fertilizers, compost, and microbial inoculants.

5. Soil Crusting

A thin, hard crust forming on the soil surface is a sign of declining structure. Crusting prevents water infiltration and air exchange, causing poor seed germination and shallow root systems.

What to do: Protect soil with mulch or cover crops. Avoid frequent tillage and add organic matter to restore aggregation and porosity.
