As any experienced gardener knows, healthy plants start with healthy soil. Top soil is the uppermost soil layer containing the organic matter and microorganisms needed to support plant life. Understanding the basics of this fundamental growing medium is critical to establishing and maintaining vibrant gardens, lawns and landscaping.
What is Top Soil?
Top soil is the top layer of the soil profile, generally the top 5-10 inches. It has higher concentrations of organic matter like decaying leaves and roots. This gives top soil its dark color and crumbly texture, allowing air and water to infiltrate. Good top soil is teeming with microorganisms that aid plant growth. It provides ideal conditions for roots to access water, nutrients and oxygen.
Key Qualities of High-Quality Top Soil
The best top soil possesses these characteristics:
• The crumbly texture holds moisture but drains well
• Neutral pH between 6.5-7.0
• At least 5% organic matter content
• Abundant microorganisms like earthworms and bacteria
• Nutrient content including nitrogen, phosphorus and potassium
To improve texture, nutrients, and microbial life, soil lacking these qualities can be amended with compost, manure, peat moss, or other organic matter.
Evaluating and Improving Your Existing Top Soil
Start by digging down 6-12 inches and analyzing the soil structure, texture, color and smell. Conduct a soil test through your local extension office or purchase a DIY test kit. This will reveal the pH and nutrient levels and recommend amendments to optimize growing conditions.
Add 2-4 inches of compost or nutrient-rich top soil blended into the existing soil to improve poor soils. Increase organic content each season with mulch, compost, cover crops or other organic materials. This nourishes the microbial ecosystem that keeps soil healthy.
