Reducing Fertiliser Costs Through Foliar Application in West Wales.

James Hughes has always believed that grass is the most valuable crop on his farm.

Running almost 700 spring-calving dairy cows across two grazing units in West Wales, his focus has always been simple: grow as much quality pasture as possible and do it as efficiently as he can.

“Our aim is to grow as much grass as we can, and we just happen to have dairy cattle on the farms to turn that grass into money.”

Like many farmers, James was looking for ways to improve nitrogen efficiency long before fertiliser prices reached record highs. After learning more about foliar nutrition through his discussion group and independent trials, he decided to introduce a Tow and Fert system as part of the farm’s nutrient programme.

The change wasn’t about abandoning fertiliser. It was about applying it differently.

“Foliar feeding is applying the fertiliser to the leaf, as opposed to broadcasting it onto the ground. The plant absorbs it.”

Over the past few seasons, that approach has become a key part of how the farm manages nitrogen.

“We’ve cut down nitrogen use by half in the last three or four years. And part of that is due to the Tow and Fert machine.”

Before moving to foliar application, the farm had already begun reducing nitrogen rates. James explained that they had reduced applications from around 40 kg of nitrogen per hectare per grazing round to 30 kg without seeing a significant change in pasture performance. Since adopting the Tow and Fert system, applications have reduced further to around 18 kg of nitrogen per hectare per round.

“But we’re down to 18 kilos of nitrogen now using the Tow and Fert machine.”

Alongside lower application rates, James believes the farm is simply making better use of the fertiliser it applies.

“We seem to find there’s a 30% reduction in the amount of fertiliser we need to apply. We’re not getting the losses that we would be applying onto the soil.”

Those savings became particularly noticeable when fertiliser prices increased.

“I think it more or less paid back for itself in the first year, but last year with elevated fertiliser prices.”

“So we saved two loads of urea, which would pretty much pay for the machine.”

The Tow and Fert has also fitted easily into the farm’s existing grazing management. Rather than changing the rotation, James simply applies nutrients after grazing once there is enough leaf for effective foliar uptake.

“We tend to follow the cows that we’d be applying the fertiliser to every 25 days anyway. So we’re keeping the same system and doing that with this machine.”

Preparing the machine has also proven straightforward.

“The filling doesn’t take a long time… It’s a pretty basic machine. Quarter hour and you’re ready to go.”

Looking back, James believes changing the way the farm applies fertiliser has been just as important as reducing how much it uses.

“We’ve come from a history of, if in doubt, chuck fertiliser out. It was cheap food, but that is not environmentally friendly and it’s not such a cheap food anymore.”

Today, his focus remains exactly where it has always been: producing as much grass as possible while making every kilogram of fertiliser work harder.

“Growing grass is our business. So we’re doing it cheaper this way.”

“I think the more we use it the more savings there are to be had.”
