Improved Clover Growth & Nitrogen Fixation Case Study
Summary.
Over one year, clover percentage increased from an average of 10% to 17% across 10 paddocks. This improvement is equivalent to approximately 49kg/ha of nitrogen (or 106kg/ha of urea) supplied through natural nitrogen fixation.
The Problem.
Many pastures struggle to maintain or increase clover content, which can reduce the pasture’s ability to naturally fix nitrogen. This often leads to higher fertiliser costs and lower pasture performance.
The Result.
Across the same 10 paddocks:
Average clover increased from 10% to 17%
Range increased from 5–15% to 8–25%
This improvement is equivalent to approximately 49 units of nitrogen per hectare, or 106kg of urea per hectare, supplied through biological nitrogen fixation rather than fertiliser.
How DCT Products Support Clover Performance.
DCT products improve soil function and support clover growth by:
✔ Improving soil structure and root-zone conditions
This allows clover to compete more effectively with grass.
✔ Increasing availability of nutrients critical to clover growth
This supports healthier clover and stronger nitrogen fixation.
✔ Supporting soil biology involved in nodulation and nitrogen fixation
This helps clover naturally fix atmospheric nitrogen.
Why This Matters.
As clover content increases, the pasture’s ability to fix atmospheric nitrogen improves naturally — reducing the need for synthetic fertiliser inputs and improving pasture performance.
Important Note.
Results will vary depending on:
soil type
climate
pasture management
existing clover content
Conclusion.
This case study demonstrates how improved soil performance can support clover growth and increase natural nitrogen fixation, leading to better pasture quality and reduced fertiliser reliance.
Average clover increased 17% in 1 Year.
This increase in clover is the equivalent of approximately 49 units of extra N per hectare or 106 kg of urea .
