| Potatoes Newest Strategic Potato Farm aiming for ‘better quality for customers’ Quality is paramount for RJ and AE Godfrey, a mixed arable farm in North Lincolnshire, which has joined AHDB’s Farm Excellence Network. he farm grows around 440 ha of main-crop potatoes for the packing market each year, in a rotation including peas, sugar beet, wheat, oilseed rape and linseed. It will become Strategic Potato (SPot) Farm North and act as a hub for farmer-to-farmer learning in the region. Director Alex Godfrey said: “We’re always interested in what we can do better when it comes to growing potatoes and we thought this was a fantastic opportunity to see some of the newest developments applied on our farm. “We hope this will benefit others in the region as well. We’re looking forward to sharing what we do and T hearing what ideas other growers have. We know there is some fantastic knowledge out there.” The business supplies the majority of its crop to the ‘free-buy’ market. Farm Manager Will Gagg says this makes crop quality of paramount importance. He said: “If we can achieve better quality in store and to our customers I’ll be very happy. If we can fine-tune and gain small amounts, one per cent here, another per cent there, it will be a very positive thing. Of course we will be looking to share those gains with others in the local industry.” The farm spans the Lincolnshire/Yorkshire border and includes two soil types, a sandy loam on the Lincolnshire Wolds and silts on the Isle of Axholme. Will is encouraging growers from both counties and soil types to attend a series of four events to be held on farm over the summer. Trials will include varieties grown for both the packing and processing sectors. He added: “The wold and the silt soils provide completely different challenges. On the wold land, we get fantastic yield, but it is harder to hold skin-finish in store long-term. On silts we get a fantastic skin-finish that holds well in store but moisture in the soil can make lifting conditions very tricky.” Growers and agronomists interested in the work at SPot North can contact AHDB Potatoes Knowledge Exchange Manager for the region, Graham Bannister. Graham said: “Alex and Will want to lead honest and open discussions on how to make positive change on farm. I am sure Northern potato growers will be as excited as I am to have them on board.” “Inspiration for farmers to adopt new technologies and make beneficial changes on farm must come from voices they are familiar with and trust. This is why AHDB is investing £1 million in our Farm Excellence Platform, across more than 50 farms in 2018, to build on and create new groups to allow more farmers to see action on farm and channel innovation to those that can use it the most.” Water conservation agent trials show potato yield increase Trials have proven that using a water conservation agent can significantly increase potato yields, which could bring in an extra £1,100 per hectare 1 , while reducing irrigation water use by approximately 25% 2 . hese results come at a key time for the agricultural industry as many growers look to consider how they can reduce water consumption and improve farm efficiency. This is in anticipation of a shift in farm subsidy payments that will reward sustainable practices. T “Further testing has proven that H2Flo can reduce the amount of water applications by 25%, saving on overall water and pumping costs” One farmer who has experienced the benefits of a water conservation agent first hand, is Norfolk based Tim Papworth. “We applied H2Flo to a block of Royal potatoes, mixed with our standard blight spray, and left an adjacent block untreated, on a well-drained sandy loam area of one of our farms near North Walsham,” says Tim. Dr Richard Collins, ICL technical www.farmingmonthly.co.uk sales manager, explains that the final digs on Tim’s farm showed that the treated plot yielded at a higher level that the untreated site, with an increase of 11 tonnes from 61.45 t/ha to 72.63 t/ha. “This improvement in productivity could directly improve farm profits by over £1000 per hectare and can be attributed to the way in which H2Flo works. “The product contains a blend of surfactants that alters the water surface tension. Therefore, this increased the spread of water through the soil profile of the treated crop, and improved re- wetting of the soil, making it more readily available for the plants,” he says. “However, the untreated plot maintained a constant moisture level with minimal pla nt uptake, which would decrease even further if dry conditions continued.” Richard goes on to outline the additional benefits of the product. “Further testing has proven that H2Flo can reduce the amount of water applications by 25%, saving on overall water and pumping costs.” With this in mind, and the pleasing results from his own trial, Mr Papworth plans to put the product to the test again this season, trying it out on a considerably larger area with multiple varieties of potato. “Given the significant cost to purchase and apply water, at roughly £99/hectare metre, I’m really interested to test the water saving benefits for myself,” says Tim. “We use an average of 0.67 hectare metres of water in a normal year, which costs us in the region of £8,600, so any saving would be a huge benefit to us and the environment.” 1 Based on a yield increase of 11t/ha and an average price of £100/t for potatoes 2 Based on trials carried out by Amega Sciences April 2018 | Farming Monthly | 19
