Tristan & DCT:
A Partnership in Growth
Tristan’s Results Using DCT Products
Tristan’s results with DCT products were achieved as part of a well-managed, whole-farm system. He emphasises that outcomes like these rely on more than the product alone they require good soil management, balanced feeding, and accurate nutrient planning. Throughout the process he worked closely with agronomists from Hills Laboratory, used independent soil testing deeper than 7 cm across multiple zones of the farm, and aligned his fertiliser and feed program to support soil biology.
Within this system, Turbo N-15 played a key role in unlocking major improvements in nitrogen efficiency, root depth, pasture utilisation, animal health, and overall productivity.
Testimony
Turbo N-15 has had a major impact on our farm system. We reduced synthetic nitrogen from 300 kg/ha/year to around 70 kg/ha while increasing pasture utilisation by 15–17%. Root depth increased from under 7 cm to more than 40 cm, drainage improved in winter, and pastures stayed greener and more resilient through summer.
We also reduced how often we needed to apply product from every 1–2 rounds to every 2.5–3 rounds.
Animal health lifted significantly: SCC dropped from ~250,000 to below 50,000, in-calf rates improved, and metabolic issues reduced.
We also saw no sign of volatilisation losses.
Overall, Turbo N-15 has helped us reduce N use, grow more pasture, and improve animal health and production.
The Science Behind Turbo N-15 Results
A. Reduction in Synthetic N Use & No Apparent Volatilisation
Farmers often see higher nitrogen-use efficiency when applying Turbo N-15 because:
It increases the retention of applied nitrogen in the soil, reducing gaseous losses.
It improves nitrogen uptake at the root interface, allowing more of each unit of N to be converted into plant growth.
It enhances microbial cycling of nitrogen, supporting more consistent N release over time.
These processes result in more pasture grown per kilogram of N applied, which supports major reductions in synthetic N inputs.
B. Root Depth Improvements (7 cm → 40 cm)
Turbo N-15 supports changes in soil structure and root physiology that:
Encourage deeper root penetration
Promote greater root mass and branching
Improve soil aggregation and pore structure
A deeper root system gives:
Better access to moisture
Improved drought tolerance
Stronger winter recovery
Less surface pugging due to better soil bearing strength
C. Improved Pasture Utilisation (+15–17%)
More efficient nutrient uptake and better root structure supports:
More balanced and even pasture growth
Higher dry matter availability from the same feed base
Improved conversion of applied nutrients into usable pasture
This directly aligns with higher pasture utilisation figures.
D. Fewer Applications Required
Turbo N-15 often provides a longer-lasting nutrient response, which can reduce application frequency because:
Nutrients remain available for longer
Soil biology remains more active between rounds
Plants maintain higher physiological performance, even in stress periods
This explains the shift from applying every 1–2 rounds to every 2.5–3 rounds.
E. Animal Health Improvements (Lower SCC, Better Calving, Fewer Metabolic Issues)
These changes are consistent with improvements in:
Pasture mineral availability
Pasture energy balance
Reduced nitrate load
More consistent feed quality through the season
Better-quality pasture improves immunity, reduces metabolic pressure, and stabilises cow performance which fits the reported reduction in SCC and metabolic issues.
