Digging Deep: How to Test and Improve Your Soil’s Organic Content

Healthy soil teeming with life is the backbone of a thriving garden. Organic matter, decomposed plant and animal material, plays a crucial role in maintaining soil health. It improves drainage, aeration, nutrient retention, and provides food for beneficial microbes. Testing and understanding your soil’s organic content empowers you to take informed decisions to nurture your plants.

Testing Your Soil:

Several methods exist to assess your soil’s organic content. Here are a few options:

  • The Feel Test: This simple DIY method involves grabbing a handful seeds to start in march zone 6 of moist soil and molding it into a ball. Sandy soil crumbles easily, indicating low organic matter. Clayey soil forms a sticky ball, while good quality soil holds its shape and forms a short ribbon when pressed.

  • Visual Observation: Look for earthworms! Their presence indicates a healthy ecosystem with good organic matter content.

  • Home Testing Kits: Basic kits available at garden centers allow you to estimate organic matter content through color comparisons.

Boosting Organic Content:

Once you have a general idea of your soil’s organic matter level, you can take steps to improve it:

  • Compost: Adding homemade or store-bought compost is an excellent way to enrich your soil. Compost provides a slow-release source of nutrients and feeds beneficial microbes.

  • Mulch: Apply a layer of organic mulch like leaves, bark, or straw around your plants. Mulch retains moisture, suppresses weeds, and decomposes over time, adding organic matter to the soil.

  • Cover Crops: Plant cover crops like clover or ryegrass during the off-season. These nitrogen-fixing plants add organic matter and improve soil fertility when tilled back into the soil.

  • Manure: Aged manure is another excellent source of organic matter. Ensure proper composting before incorporating it into your soil to avoid weed seeds and pathogens.


  • Soil testing through professional labs¬†provides the most accurate assessment of your soil’s health and nutrient content.
  • Adding organic matter is an ongoing process.¬†Regularly amending your soil over several seasons will lead to significant improvements in its structure and fertility.

By understanding your soil’s organic content and incorporating these practices, you can create a thriving environment for your plants and ensure a bountiful harvest.
