TERAhume · Soil restoration

The living surface.

TERAhume helps rebuild the organic matter, structure and soil life that let water, air and roots move through your soil.

Why soil matters

Healthy topsoil makes room for water and roots.

A closer look at the soil shows how its structure shapes the space available below the surface.

Look at the surface layer

Organic-rich topsoil

Organic matter helps keep topsoil crumbly, giving young roots room to spread.

Follow the water

Connected soil pores

Connected pores let rain soak deeper into the soil instead of staying near the surface.

Structured soil below

In structured soil, roots have room to grow deeper below the surface.

How it works

Life starts below the surface.

Takeaway

TERAhume supports the natural process that turns organic material into stable, living soil.

  1. Leaf litter, crop residues and fine roots

    Organic inputs

    Material goes in.

    What happens: Residues and roots add organic material to the soil.

  2. Dark, partly broken-down organic material in moist soil

    Soil biology

    Life transforms it.

    What happens: Soil organisms break it down and rebuild it into organic matter.

  3. Stable, crumbly soil aggregates with pore spaces and fine roots

    Soil structure

    Structure holds together.

    Why it matters: Stable crumbs and pores hold water and give roots room.

Carbon follows several pathways. Some may be retained within aggregates or associated with minerals; some returns to the atmosphere as CO₂.

What we look for

Roots reveal the conditions around them.

Before choosing an approach, a soil check reads signs like these. They guide what to investigate; they are not a treatment result on their own.

  1. 1. Branching in the topsoil

    Young roots explore loose, crumbly soil near the surface.

  2. 2. Roots turning sideways

    A dense layer can deflect roots and limit access to the profile beneath.

  3. 3. Few roots below the layer

    Less of the profile is used for water and nutrients.

Soil assessment with TERAtest

How it fits your site

A response shaped by the site.

No two estates are the same, so the approach starts with your soil, not a fixed recipe.

  1. Step 1: Understand the soilwith TERAtest

    Identify the physical and biological conditions that need attention.

  2. Step 2: Apply TERAhume to fit the site

    Match the approach to the crop, land and how your team works.

  3. Step 3: Observe how the soil responds

    Check the same soil signs at each visit and adjust the plan.

  1. 1. Start with your own soil

    Every plan begins with what is in the ground at your site: its structure, roots and soil life.
