Rethinking Fertilisation: A Smarter, More Sustainable Approach

The Tow and Fert system dissolves globally available granular fertilizers for efficient foliar application, reducing costs and promoting cleaner nutrient management.

Current traditional fertiliser application methods contribute significantly to greenhouse gas emissions (GHGs), nitrate leaching, and inefficient nutrient use. Tow and Fert’s innovative Fine Particle Application (FPA) technology provides a science-backed, scalable solution that:

Reduces nitrogen inputs by 30-47% while maintaining or increasing yields​.
Decreases volatilisation and nitrate leaching, improving water quality​​.
Supports corporate sustainability goals without sacrificing productivity​.

By adopting Tow and Fert, corporate food producers and agribusinesses can meet sustainability commitments, enhance farm profitability, and future-proof their supply chains.

The Science Behind Our Approach:

Fine Particle Fertilisation vs. Traditional Methods

Scientific research from University of Canterbury, Massey University, and industry trials has proven that applying nitrogen in fine particle form significantly increases efficiency compared to traditional granular applications.

Application MethodNitrogen Efficiency (kg DM/kg N)Nitrate Leaching (%)
Granular Urea10 kg DM2.1%
Fine Particle Urea19 kg DM0.92%
Fine Particle Urea + Agrotain23 kg DM0.04%

Data sourced from “Urease inhibitor reduces N losses and improves plant-bioavailability of urea applied in fine particle and granular forms under field conditions” (Dawar et al.) 1 and additional field trials conducted by industry researchers​ that back up this data 2,3,4.

Switching to foliar-applied fine particle fertilisers means more nutrient uptake, less waste, and better environmental outcomes.

Reducing Volatilisation and Environmental Impact

Traditional granular urea leads to nitrogen losses through volatilisation, increasing GHG emissions​.
FPA technology delivers nutrients directly to plants, minimising loss and maximising efficiency​.

Cutting Emissions: A Smarter Approach to GHG Reduction

Traditional Fertiliser Applications & GHG Impact

Conventional nitrogen fertiliser use is a major contributor to agricultural GHG emissions, particularly through:

  • Nitrous oxide (N₂O) emissions, a greenhouse gas 300x more potent than CO₂​.
  • Ammonia volatilisation, leading to nitrogen losses and increased atmospheric pollution​.
  • Excess nitrate leaching, which not only harms water quality but also contributes to indirect emissions​.

Tow and Fert’s Role in Reducing Agricultural Emissions

The increased Nitrogen Use Efficiency (NUE) through foliar application results in key environmental benefits:

Lowering N₂O emissions compared to traditional granular urea.1
Reducing ammonia volatilisation, ensuring more nitrogen reaches the crop and less escapes into the atmosphere.1
Minimising nitrate leaching, protecting waterways and reducing indirect emissions.1

The Tow and Fert system uniquely addresses the challenges allowing farmers to continue with thier using the granular fertiliser products that are globaly available and turning them into a more efficient foliar application. This results in costs saved for the farmers bottomline, while contributing to cleaner nutrient management practices.

Understanding N₂O Losses from Urea Application: Granular vs. Fine Particle

This graph compares nitrous oxide (N₂O) losses from 100 kg/ha of urea applied in granular (G) and fine particle application (FPA) forms. The data shows that:
  • Granular Urea (G) resulted in 0.42 kg N₂O-N/ha, with 0.26% of applied nitrogen lost as N₂O.1
  • Fine Particle Application (FPA) of Urea reduced emissions slightly to 0.40 kg N₂O-N/ha, corresponding to 0.24% of applied N—a 5% lower emission rate compared to granular urea.1
To highlight efficiency, the dashed line in the graph represents what N₂O losses would look like if the FPA application rate were reduced by 40%.
