First Year of GrassCheckGB Programme Delivers Strong Results

The first year of the GrasscheckGB programme has delivered strong results for the nine beef and sheep pilot farms in Scotland.

GrassCheckGB aims to improve grassland productivity and pasture utilisation on beef and sheep farms through a grassland performance monitoring network.

This project is a collaboration between Quality Meat Scotland (QMS), Hybu Cig Cymru – Meat Promotion Wales (HCC), the Agriculture and Horticulture Development Board (AHDB), together with the Centre for Innovation Excellence in Livestock (CIEL) and researchers at the Agri-Food and Biosciences Institute (AFBI) and Rothamsted Research, as well as industry sponsors Germinal, Waitrose & Partners, Sciantec Analytical and Handley Enterprises Ltd. CIEL is supporting the purchase of equipment on farms through funds from Innovate UK, the UK’s Innovation Agency.

Pilot farmers are required to measure grass each week throughout the growing season, with regular grass samples taken for quality analysis. Each farmer has an electronic plate meter to measure grass yield on their farm and an automatic weather station to record key metrological data such as temperature, rainfall and sunshine hours.

The recent end of year report has highlighted Scottish on-farm grassland production averaged 11.298 t DM/ha. Through rotational grazing and measuring grass weekly, Scottish farms managed to utilise over 80% of the grass grown, showing a high level of technical expertise from the Scottish pilot farmers.

Regional grass growth differences were shown to be linked to weather conditions, with the south of England experiencing extreme summer heat followed by a very wet autumn. This was confirmed by the on-farm weather station data with Scotland recording the UK’s highest grass growth rates during June and July due to an ideal combination of soil moisture and temperature.

One of the pilot farmers, Dane Davidson of Brogan Farms near Ellon said he has seen many benefits of being part of the project: “At Brogan Farms we are using the data collected through GrassCheckGB to analyse our overall farm grass availability, allowing us to better plan our grazing.  The aim is to achieve a higher quality and more consistent level of grass availability that matches the stock needs throughout the season.

“We are a sheep breeding and finishing enterprise which also buys store cattle to graze through the summer depending upon grass availability. 

“Measuring and monitoring grass for GrasscheckGB has let us gain a greater understanding of the farm’s annual grass growth curve and average farm cover at any given time. This is useful when deciding upon the number and timing of store cattle purchases in the spring as well as store lambs in the autumn. Grass growth here peaked during late May which  coincided with our lambing ewe’s peak lactation.,”

Dane commented: “With the on-farm weather station, we can see the direct effect local weather conditions have on grass growth and then understand the national differences by comparing data against other Grasscheck GB farms.  Grass production tripled from April into May as air temperatures increased and over 60 mm of rain fell which provided adequate moisture to soils after a relatively dry April.”

John Ritchie of Montalt Farm near Perth who is also part of the GrassCheckGB project commented: “The output at Montalt farm has increased from 380 kg to 540 kg of live weight sold per hectare over the last five years because we’ve learned how to utilise our grass better by rotating stock and measuring,” explained Mr Ritchie. “As a business, we are now looking to grow an average of 9000kg of dry matter per hectare on our improved ground.”

Mr Ritchie added that paddock grazing has also helped him reduce fertilizer use significantly.

“In 2019 we didn’t use any fertilizer on our grazing fields and hope this will continue due to better understanding of grass management. Only 75 units of Nitrogen has been used on the ground set aside for silage and we are looking to reduce this further in the future,”

John Evans, Cattle and Sheep Specialist with Quality Meat Scotland (QMS), said: “We’ve just entered the second year of the GrassCheckGB programme and farmers will continue to measure grass each week until October, which will be reported to the industry on a weekly basis.

“The automated on-farm weather stations will continue to take regular readings and this, along with the grass data, will allow farmers to make timely management decisions.”

GrassCheckGB publishes weekly summary bulletins on twitter (@GrasscheckGB) throughout the grazing season, detailing average farm grass growth rates across the country, soil conditions and weekly total rainfall. Bulletins include management notes tailored to the current conditions recorded on project farms throughout the grazing season.
