Poor Root Development Despite Good Top Growth – Field Results & Agronomic Interpretation
Strengthening Roots for Consistent Pasture and Crop Performance.
Some pastures and crops appear healthy above ground but have limited root development, which reduces nutrient and water uptake and makes plants vulnerable to stress. Field observations show that supporting soil function with DCT products improves root growth, nutrient absorption, and overall resilience.
This approach focuses on supporting soil biology and nutrient cycling rather than applying more fertiliser alone.
Field Observation Summary
Treated pastures and crops showed deeper, stronger roots over one to two seasons.
Improved root systems resulted in more uniform top growth and better drought resilience.
Soil testing indicated higher microbial activity, contributing to nutrient availability and enhanced root function.
Evidence Context
Important context
These results were observed across multiple soil types and pasture or crop species. Soil texture, moisture, and management practices affect outcomes.
International agronomic studies support these observations, showing that healthy soil microbial activity is linked to stronger root growth and improved nutrient efficiency.
Agronomic Interpretation
Root development is influenced by soil structure, biology, and nutrient cycling:
Compacted or stressed soils restrict root expansion.
Low microbial activity reduces nutrient availability and slows root development.
Inefficient nutrient cycling limits the resources available for strong root growth.
Supporting these processes improves root depth, nutrient uptake, and plant resilience, even when top growth appears healthy.
Where This Fits in the Farming System
DCT products support root development and soil function, complementing standard fertiliser and grazing management.
While mechanical interventions may be necessary in extreme cases (e.g., severe compaction), field results show significant improvement in root systems with consistent product use.
Works best as part of an integrated system including soil monitoring, drainage management, and pasture planning.
Products Used in the System
Lazerhume – Supports microbial activity, helping roots access nutrients and water.
Restore – Provides additional biological support for stressed soils and enhanced root development.
Turbo N – Supports nutrient uptake and promotes consistent above- and below-ground growth.
Optimise iO – Enhances microbial diversity and nutrient cycling, improving overall root health.
Agronomy Insight
Agronomy insight
Strong roots are essential for nutrient uptake, water use, and plant resilience. Supporting soil biology and nutrient cycling encourages deeper, more uniform root systems, which improves pasture and crop performance, even when above-ground growth appears adequate.
When This Approach Has Limits
Very compacted soils or soils with poor structure may still require mechanical remediation.
Extremely dry or waterlogged conditions can limit root expansion.
Even in these situations, supporting soil biology improves nutrient availability and resilience for future growth cycles.
Key Takeaway
Improving root development is not just about fertiliser or visible top growth. Field observations show that supporting soil biology and nutrient cycling with DCT products leads to stronger, deeper roots, better nutrient uptake, and more resilient pastures and crops.
