Improved Soil Structure & Biological Function Case Study

Summary

Improved soil structure creates better aeration and drainage, which supports healthy soil biology. This improves nitrogen fixation and nutrient cycling, leading to stronger pasture growth and better root development.

The Problem.

Many soils become compacted and poorly structured over time, reducing air-filled pore space and limiting soil biology. This reduces:

root growth and function
nutrient cycling
nitrogen fixation
pasture performance

What Was Done.

DCT products were applied to improve soil structure and support soil biology, creating the conditions needed for a functioning, nutrient-cycling soil system.

The Result.

Improved soil structure leads to:

✔ More air-filled pore space
✔ Better aeration and drainage
✔ More active microbial life
✔ Improved root growth and pasture establishment

How DCT Products Support Soil Structure.

Improved soil structure increases air-filled pore space, which is essential for healthy soil biology.

Better aeration supports:

Nitrogen-fixing bacteria on clover roots
Other beneficial soil microbes
Microbial processes that convert fixed nitrogen into plant-available forms

An open, well-aggregated soil structure also:

Improves drainage and reduces waterlogging
Supports a resilient microbial population
Encourages deeper, healthier root growth

Why This Matters.

By improving soil structure, DCT products help create the conditions needed for soils to function as a biologically active, nutrient-cycling system — not just a growing medium. This supports long-term pasture performance and productivity.

Conclusion.

This case study demonstrates how improving soil structure can unlock biological function, enhance nutrient cycling, and support stronger pasture and root growth.
