Understanding Bioactive Soil Mixes

What is a Bioactive Soil Mix?

A bioactive soil mix is a specially formulated growth medium that supports a thriving ecosystem of plants, microfauna, and microflora. These mixes promote a self-sustaining environment, replicating natural habitats by facilitating nutrient cycling and decomposition of organic matter.

The Importance of Bioactive Soil Mixes

Bioactive soil mixes are essential for maintaining a healthy and diverse ecosystem within your terrarium or vivarium. By providing the necessary nutrients, moisture, and aeration, these mixes encourage plant growth, support beneficial microorganisms, and create a suitable habitat for your pets.

Factors to Consider When Choosing a Bioactive Soil Mix

Base Material

The base material of a bioactive soil mix should have excellent water retention properties. Some popular choices include coco coir, sphagnum moss, and peat moss.

Drainage and Aeration

A good bioactive soil mix should provide adequate drainage and aeration to prevent compaction, waterlogging, and root rot. Common additives to improve drainage and aeration include orchid bark, lava rock, charcoal, and pumice.

Nutrient Content

The mix should contain ample organic matter to supply essential nutrients for plant growth and support the needs of microorganisms. Some popular nutrient-rich additives are earthworm castings, compost, and leaf litter.
