[QUOTE="Agriland RSS, post: 7490057, member: 105608"] [img]https://s3-eu-west-1.amazonaws.com/files.thefarmingforum.co.uk/images/agrilanduk.JPG[/img] Written by William Kellett Farmers growing spring wheat this year should consider applying foliar nitrogen to improve crop efficiencies and boost protein content in milling varieties. Given that prilled urea or ammonium nitrate is only 60% efficient in ideal conditions – and can’t be taken up by the plant when the soil is dry or too wet – using foliar nitrogen in a tank mix with fungicides, PGRs or herbicides makes considerable financial and environmental sense. “Although foliar nitrogen seems more expensive, it is 85-90% efficient, so on a per hectare basis it is comparable,” explainsed Doug Chaplin, managing director at Micromix Plant Health. Producers may choose to use conventional soil-applied products early in the spring and then switch to foliar applications later, or take the foliar option throughout. “You want to apply at the start of spring growth, and it’s best to apply little and often – typically whenever you’re applying fungicide or herbicides as a tank-mix to minimise the number of field passes and save on fuel,” said Chaplin. [SIZE=5][B]Important to choose product correctly[/B][/SIZE] It’s important to choose a product which won’t scorch the crop though – for example Multi-N has a non-scorching formulation and can be applied in a low dilution, reducing the volume of water required per tank. Chaplin explained: The formulation includes three forms of nitrogen: Ammoniacal nitrogen; urea thiosulphate; and nitric nitrogen, which supply both slow and quick release nitrogen and a bio-available form of sulphur. “The nitric form is instantly available once absorbed by the leaf,” explained Chaplin. “The fast-acting sulphur is immediately incorporated into S-rich amino acids which are key components of grain protein.” [SIZE=5][B]Milling wheat[/B][/SIZE] For milling wheat, Mr Chaplin suggests applying 5l/ha at growth stage 25, 15l/ha around GS32 (stem extension), and then 40l/ha at GS59 to boost the grain protein content. “Last year, many producers opted to grow spring barley following the awful wet autumn, but margins were not that great, and this year the level of demand for malting varieties is unclear,” explained Chaplin. “But it will be important to maximise both yields and quality for optimum returns, which means giving the crop the best support possible,” he concluded.
