Versatility in One Pass
Apply fertiliser, seed, trace elements, and animal health products together.
Smarter Nutrition for Profitable Dairy Systems
Tow and Fert technology gives dairy farmers the ability to produce more grass with less nitrogen. By dissolving and suspending fertiliser, trace elements, and even animal health products into a foliar-ready form, nutrients are delivered more efficiently and absorbed faster. With flexibility to apply in almost any weather and the ability to combine multiple products in one pass, you save money, time, and stress while improving herd health and soil performance.
With Tow and Fert:
Foliar Nitrogen Savings
Achieve the same or better pasture growth with up to 50% less nitrogen.
Flexible Timing
Apply even when rain is forecast — no need to wait for dry conditions like granular fertiliser.
Animal Health on the Leaf
Apply magnesium, selenium, cobalt, or iodine directly to the pasture for uptake, avoiding dosatrons or in-feed supplements.
Dust-Free Applications
Suspend magnesium oxide and fine lime directly in the tank — no clouds of dust in front of the herd.
Dairy Farming with Tow and Fert
Smarter Nutrition for Profitable Dairy Systems
New Zealand dairy farming is operating in a tighter, more scrutinised environment than ever before. Milk price volatility, rising fertiliser costs, nitrogen limits, and pressure to lift efficiency all mean the old approach of applying more granular fertiliser is no longer stacking up.
Tow and Fert gives dairy farmers a smarter way to manage nutrients by dissolving and suspending fertiliser, trace elements, lime flour, and biological products into a foliar-ready form. This allows nutrients to be applied precisely, efficiently, and at the right time, improving uptake while reducing waste, cost, and environmental loss.
Instead of relying on a single nitrogen-heavy application strategy, dairy farmers are using Tow and Fert to build more flexible, responsive nutrient systems that support pasture growth, herd health, and soil performance year-round.
Why Dairy Farmers Are Moving to Foliar and Fine Particle Nutrition
Across New Zealand and internationally, dairy farmers are shifting toward foliar and fine particle inputs as part of a more efficient nutrient management strategy.
Traditional granular fertiliser relies on soil moisture, temperature, and time to become available to plants. A large portion can be lost through volatilisation, leaching, or immobilisation before it ever reaches the pasture.
Foliar and fine particle applications work differently. By delivering nutrients directly to the leaf and soil surface in a soluble or suspended form, plants can access what they need faster and in smaller, more precise doses. This approach improves nutrient use efficiency and reduces reliance on high nitrogen rates.
Tow and Fert systems are designed specifically to make this practical at dairy scale. Farmers can apply nitrogen, sulphur, magnesium, trace elements, lime flour, seed, and biological products in one pass, tailored to pasture demand and seasonal conditions.
Getting More From Every Dollar of Fertiliser
When milk price and fertiliser pricing both fluctuate, efficiency matters more than ever.
Tow and Fert helps dairy farmers:
-
Reduce nitrogen rates while maintaining or improving pasture growth
-
Apply nutrients when conditions suit the plant, not the spreader
-
Avoid over-application and wasted product
-
Combine multiple inputs into a single pass to save time and fuel
Many dairy operators report achieving similar or better pasture response with significantly less nitrogen by using foliar applications supported by trace elements, sulphur, and biological inputs that improve nutrient uptake.
By focusing on nutrient efficiency rather than total tonnes applied, Tow and Fert supports more resilient farm systems that perform under both high and low payout scenarios.
One Machine, Multiple Jobs, All Year Round
Tow and Fert machines are not just nitrogen applicators. They are a year-round nutrient delivery platform designed to fit seamlessly into modern dairy systems.
Dairy farmers use Tow and Fert to:
-
Apply foliar nitrogen, sulphur, and trace elements for fast pasture response
-
Deliver magnesium, selenium, cobalt, and iodine through the pasture rather than in the shed
-
Apply lime flour to maintain soil pH without heavy machinery or downtime
-
Establish and oversow pasture with small seed
-
Apply biological products without damaging living organisms through high pressure
Because Tow and Fert operates at low pressure and uses high-energy agitation, it can handle products that conventional sprayers and spreaders cannot.
Supporting Animal Health Through the Pasture
Many dairy farmers are using Tow and Fert to deliver animal health minerals directly onto pasture. Magnesium, selenium, cobalt, and iodine can be applied evenly across the paddock, improving intake consistency and reducing reliance on in-shed dosing systems.
This approach supports:
-
More even mineral intake across the herd
-
Reduced labour and handling
-
Better alignment between pasture nutrition and animal demand
Applied little and often, these inputs become part of a proactive animal health strategy rather than a reactive fix.
Built for Dairy Scale and Proven on New Zealand Farms
Tow and Fert machines are designed and built for New Zealand conditions and dairy scale. From smaller operations through to large herds, farmers are using Tow and Fert as a core part of their nutrient management system.
With proven performance across New Zealand and overseas, Tow and Fert supports dairy farmers who want to:
-
Grow more grass with less nitrogen
-
Reduce input costs without sacrificing production
-
Improve nutrient efficiency and system resilience
-
Future-proof their operation under increasing environmental pressure
A Smarter Way Forward for Dairy Farming
Dairy farming is no longer about applying more inputs. It is about applying the right inputs, at the right rate, at the right time.
Tow and Fert gives dairy farmers the tools to take control of their nutrient programme, respond to changing conditions, and build more profitable, efficient systems that work today and into the future.
Mix Examples
Tow and Fert machines aren’t just for nitrogen. Our Dairy Calendar of Uses shows how you can get year-round value from your machine by applying:
Spring
Foliar nitrogen, magnesium, and trace elements to drive early growth and prevent animal health issues.
Summer
Foliar nitrogen, sulphur, and trace elements; apply seed for summer crops and maintain pasture quality.
Autumn
Lime flour, animal health products (Mg, Se, Co, I) and foliar fertiliser to strengthen pasture heading into winter.
Winter
Urea with urease inhibitors, magnesium and animal health minerals, plus fine lime applications to maintain soil pH.
