College improves manure use with spreader weigh cell technology

An agricultural college in north-east England is reducing costs and improving soil fertility by using a small and compact Bunning Lowlander 80 TVA manure spreader, with weigh cells, to match manures to field requirements via detailed nutrient maps.

With livestock numbers steadily growing and pressure to stay well within environmental guidelines at East Durham College farm, Houghall Campus, on the edge of Durham, Paul Flynn, director at the college, wanted to use the manure in a targeted way to reduce the reliance on purchased fertiliser and move to a clover-based grassland system.

Paul explains: “The only way to do this is by accurately applying the tested manure to areas of the farm that need it, which means using modern and precise equipment, such as the Bunning Lowlander 80 TVA with weigh cells. Before the Lowlander 80 TVA arrived, we used two old Marshall barrel spreaders that weren’t up to modern precision or standards. We employed a contractor as well, but I wanted to bring the process in-house for the benefit of the farm and the students.”

The college took delivery of a Bunning Lowlander Farmstar 80 TVA in 2022 and Ben Johnson from Bunning supported the team to set the spreader up on the New Holland T6 and train the staff using the application software. “Once set up, the spreader can work very quickly, adjusting the floor speed to control the application rate and follows the field map within 2cm,” says Paul.

The college grows arable crops alongside grassland, providing a home-grown food source for the animals. The cattle, sheep and even the pigs are all home fed, keeping the nutrients within the farm and returning them to the land in a natural cycle.

Weigh cells

Part of the spec included weigh cells, which allows the operator to weigh each load that passes through the machine and keep accurate field records and helping to create consistent fertility across the field. Even applications make the field easier to harvest and improves the quality of production. Weigh cells are an option on all Bunning spreaders, and the 80 TVA is one of the smallest units in the portfolio, and the technology has benefits on every machine, as Ben explains.

He says: “Our smaller twin vertical auger spreaders aren’t known for their technology. However, by fitting weigh cells via Isobus to the Lowlander 80, it proves that by combining a simple spreader and the right technology, the whole process has become more efficient and cost effective, with greater returns from the manure.

“Weigh cell technology has benefits regardless of the size of machine. From recording applications on a field-by-field basis to spreading product using soil mapping data, the technology helps every spreader apply manures with greater efficiency.”

The 210ha farm is surrounded by the River Wear, so each application is measured and recorded to stay within recommended levels. Paul is hoping the farm can demonstrate best practice and is working closely with the Wear Rivers Trust to achieve this. Northumberland Water, together with the Trust are launching a ‘Thriving Catchment Partnership’ the college has already started to support this with a series of practical events for farmers and is hoping to become a ‘Demonstration Farm’ for the partnership.

Spreader operation

Farm manager Keith Cook and assistant farm manager Ian Whitfield handle the farm operations alongside supporting the students with practical experience. Keith says since the spreader has arrived it has made a significant difference to the value of manure and eased the whole spreading operation.

“We can now quantify the nutritional value of the manure and apply it accurately. Bagged nutrition should always be a backup to this and now we can make this a reality. We know what the manure contains, and the weigh cells record how much and where we’ve applied it. This is then deducted from any bagged fertiliser we use in the spring to ensure our soil nutrients remain at the right level.”

The Bunning Lowlander 80 TVA runs through the external ISOBUS screen in the cab. This makes setting up and operating the spreader simple, with on-the-go manure quantities displayed to assist with filling logistics in the field. All the settings are controlled through the screen which, combined with the tractor’s GPS, makes the operation very efficient.

The Lowlander 80 spreader is powered by a 2023 New Holland T6.180 and the combination enables the farm to time applications to suit the crop and the soil. To help reduce compaction, Bunning fitted larger tyres – 520/85 R38 – to increase the rolling resistance and spread the weight of the machine on the soil. The spreader has an 8t capacity, which is ideal for the size of the college’s fields, while the consistent spread pattern has impressed all users.

Keith continues: “It has a reliable spread pattern and product delivery, easily breaking down large lumps of well-rotted manure. We try and help the composting process by turning our heaps before spreading. This helps create an even product and the Lowlander can apply this uniformly across an 8-10m wide pass.”

“We set the target application rate and then drive the spreader at a speed to achieve this. The Lowlander 80 is still short enough to access our fields. Any longer and the machine would struggle to turn into some gateways, so it is the right combination, allowing good output and manoeuvrability. The technology on the Lowlander has increased efficiency for our farm,” concludes Keith.
