Grassland Trials
Research and Development of Grassland Fertilisers
Grassland Trial Results
Take a look at some of our Grassland Trials using Liquid Fertiliser
At OMEX we’re passionate about providing farmers with quality research and results on the fertiliser they’re using on their grassland. Over 50 years our R&D team have worked on multiple research projects, ranging from product efficiency to understanding the most effective application rates.

Productivity of Grassland Field Margins
Ensuring nitrogen grassland fertiliser is applied at full rate to the edge of the field but no further is a key issue. Despite ongoing advances in spreader design, it is not possible for a spinning disc to apply an even distribution pattern if the operator is to guarantee that no fertiliser travels beyond the edge of the field.
Yield loss from the outside 8m of a field has been shown to be 3.5t/ha of winter wheat and 10t/ha of potatoes when nitrogen is applied through a spinning disc spreader. The outside 8m of a 15ha field represents 5% of the field, creating a large yield and financial loss for the farmer, making the fertiliser operation largely inefficient.
By using Nitroflo, it is possible to apply the full rate of nitrogen right up to the field margin: no compromise to yield, no risk of applying fertiliser beyond the field margin.

Liquid Nitrogen on Grassland Trials
This grassland fertiliser trial assessed Nitroflo v SulfaCAN.
This liquid nitrogen grassland fertiliser versus SulfaCAN trial was conducted in South Tipperary in June 2020. The trial was conducted on two paddocks of Perennial Ryegrass, both reseeded on the same day.
The results showed after 14 days 53% more grass with less units of nitrogen when Nitroflo was used.

Nitroflo v Protected Urea Grassland Trial
This liquid nitrogen grassland fertiliser versus protected urea trial was conducted in North Tipperary in July 2020. The trial was conducted on two side by side paddocks of Perennial Ryegrass
The results showed after 14 days 65% more grass with the same units of nitrogen when Nitroflo was used.

Liquid Fertiliser compared to Granular Fertiliser Trial
The below trial demonstrates the visual impact of utilising granular urea in comparison to liquid nitrogen Nitroflo on grassland:
The New Zealand style grazing dairy unit in Staffordshire applied OMEX Nitroflo S, on the same day as urea on adjoining grazing paddocks. The pictures below, taken at the same time, show the difference in DM production following application of Nitroflo, Liquid Nitrogen.
Silage Grass: The picture sequence below shows a field after second cut silage.
The crop was cut on 16 July, picked on 17 July, then grazed for two days. On 20 July OMEX Nitroflo S was applied at a rate of 112kg/ha (90 units/ac). Despite the drought, uptake of N was very rapid and a visual difference could be seen within two days.

The Benefit of Liquid NPKS Fertilisers for Grassland
This grassland trial assessed a Multiflo NPKS grade in comparison to a granular alternative. The liquid nutrition within Multiflo showed a clear increase in Fresh grass yield.
Multiflo liquid NPKS fertilisers offer a number of benefits to grassland farmers:
- Greater accuracy of fertiliser to the crop
- Delivery of product when needed
- OMEX tank system supplies potato farmers with dedicated on-farm storage
- 100% soluble, high quality, P source
- Targeted application
- Sustainable fertiliser choice – application right up to the field margin and not beyond
Multiflo works as a precision farming tool for grassland farmers. Precision Farming Many of the UK’s most innovative precision farmers use liquid fertilisers due to the ease of controlling the application rates and the ability to automatically regulate individual boom sections.
Including Polymex with your Multiflo phosphorus containing grade can improve the availability of phosphorus to the grassland crop.
