Optimise i-O – Improve Urea Efficiency and Soil Health

Optimise i-O is a liquid soil activator designed to improve the efficiency of applied urea. By reducing nitrogen losses, supporting nutrient uptake, and enhancing soil biological activity, it helps growers get more from every kilogram of urea while improving soil function.

The Problem: Nitrogen Loss in NZ Soils

Urea is widely used as a nitrogen source, but up to 50% of applied nitrogen can be lost before plants access it due to:

• Volatilisation (ammonia loss)

• Leaching below the root zone

• Denitrification by soil microbes

These losses reduce crop or pasture growth and limit the return on fertiliser investment.

The Solution: Optimise i-O

Optimise i-O works in combination with urea to:

• Reduce nitrogen loss and improve retention in the soil

• Enhance nutrient uptake by plants

• Support beneficial soil microbes to maintain active nutrient cycling

• Improve soil structure and water retention, promoting resilient soils

For growers seeking higher biological stimulation and additional nutrient efficiency, Optimise Pro provides extra seaweed content for enhanced soil and plant performance.

How It Works

Optimise i-O enhances soil–root–plant interactions:

• Retains more nitrogen in the soil for plant uptake

• Supports root growth and soil microbial activity

• Improves nutrient cycling and soil structure without adding additional chemical inputs

This combination helps crops and pastures access nitrogen more efficiently, supporting early growth and overall productivity.

Observed Benefits

• Maximise Your Investment: More nitrogen remains available to the crop or pasture

• Faster Growth: Improved early nitrogen uptake supports consistent development

• Stronger Yields: Efficient nutrient use contributes to higher crop or pasture performance

• Resilient Soil: Long-term support for soil biology and structure

• Cost-Effective: Reduces nutrient loss and increases return from applied fertiliser

Note: Performance varies depending on soil type, climate, crop species, and overall management practices.

How to Use

• Mix Optimise i-O directly with urea before application

• Application rate: 15–20 L per hectare

• Compatible with standard farm machinery and repeatable across multiple applications
