b'contributes to about 20 per cent ofhigher greenhouse gas emissions peryour on-farm potato production.greenhouse gas emissions. And of that 20french fry. So, the on-farm emissions may per cent, five per cent comes from mineralincrease or decrease from year to year,SS: Why is it important to fertilizer use and six per cent comes frombut that may be able to be balanced bysustainability to manage tuber mineral fertilizer production. Lets look atreduced emissions at a different point inquality at harvest and storage?greenhouse gas emissions in the potatothe cycle. EW: The idea here is really to provide industry, using the life cycle assessment ofthe crop with the nutrients that it needs a frozen french fry.SS: How can you reduce on farmto grow a high-quality crop in the grade On-farm emissions make up about 18fertilizer emissions as a potatoyoure looking for in the end, which per cent of total emissions of that finalgrower? should reduce waste, it should reduce loss frozen french fry product. Whereas theEW: One consistent way is to choosein storage, and it should reduce waste at activities at the processor make up aboutinputs that are manufactured withthe processor. 33 per cent of the overall emissions,processes that have a low carbonFor tuber grade, if youre growing a retailer 11 per cent, and consumer andfootprint. At Yara weve actually beenseed crop or a chip crop and you want a foodservice actually make up about 38working to reduce our emissions in thehigher tuber set, Id recommend making a per cent of overall emissions. There aremanufacturing process for 20 years. Werephosphorus application at tuber initiation. a lot of factors that make up the finalleading in reducing emissions in theCalcium can also increase tuber size, lifecycle assessment for a french fry,manufacturing of nitrate fertilizer throughits very important for tuber quality. I and as an industry, theres a potential tothe use of nitrous oxide abatementwould recommend using calcium but reduce emissions at many points in thecatalyst technology and energy efficientalso making sure to use the shot of lifecycle.measures.phosphorus at tuber set initiation.For on-farm emissions, there maySo already, our nitrate-basedEveryone knows that nitrogen is an be years where our greenhouse gasEU-produced fertilizers have a 50 toimportant nutrient for the crop. But its emissions per french fry are really low,60 per cent lower carbon footprintalso important to manage your nitrogen because we had a great yield great quality,compared to other non-EU fertilizers. Inwell, because too much nitrogen favourable weather, and used inputsthe future, were also looking at usingparticularly late in the season can efficiently to drive higher yield and reducerenewable energy resources in additionnegatively impact quality.
