New trial results highlighting the importance of key nutrient application timing and the latest thinking on fertiliser use in a climate change future have been launched by CF Fertilisers.
Analysis of latest trials were highlighting some important ways growers could improve Nitrogen utilisation, said CF Fertilisers arable agronomist Allison Grundy.
“Initial results are showing yields in wheat can be improved by up to 1.0t/ha by applying P and K alongside N and S in the spring rather a separate dressing in the autumn as is the conventional practice.
“There is strong evidence emerging that plants can more efficiently utilise Nitrogen to build yield when all these key nutrients are applied in a single spring NPKS granular product than separately.
“Other trials are showing how evaluating soil reserves of Nitrogen more accurately can reduce fertiliser costs by up to 20% whilst maintaining high output yields of 10.0t/ha plus.”
CF Fertilisers is also the lead company in a consortium of businesses including Syngenta, Hill Court Farm Research, Patchwork and Precise Crop Nutrition, evaluating the ISARIA system – a new type of crop sensor developed by the German company Fritzmeier.
“Trials carried out in winter wheat in the first year of the project showed an average yield advantage of 0.4t/ha from the system and ADAS are now reviewing the second year of trial results in winter barley, winter wheat and oilseed rape,” she said.
A focus on the essential role of Nitrogen in achieving future environmental and sustainable production targets was also a feature of the stand with CF Fertilisers having copies of its new ‘Our Actions Speak Louder than Words’ document available to growers for the first time.
“Without fertiliser, we would need the manure from up to 7 billion more cattle globally to maintain soil fertility. Feeding those cattle would mean clearing nearly all our remaining forests to grow grass,” said Sam Bell, head of sales and marketing for CF Fertilisers.
“Furthermore, a crop of wheat grown with the right amount of fertiliser will produce up to six times more energy and capture twelve times more carbon dioxide from the atmosphere than is required to produce, transport and apply the fertiliser in the first place.”
