A change in the period for the application of N and P fertilisers – following the revised Statutory Instrument (SI) enacting the Nitrates Directive – has got to be good news to cereals farmers.
Nutri-Phite PGA trials on wheat
Up until now use of all chemical fertilisers was prohibited from 15 September until January but now – provided the application rate is less than 1kg per hectare of available nitrogen or phosphorus – there is no time constraint.
Plant Syence has been instrumental in steering this change providing a large dossier to support the use of patented technology. This has demonstrated that applications of its products improve the plants ability to scavenge more nutrients from the soil than are applied therefore increasing the fertiliser efficiency and reducing potential loss in the environment. Liquid foliar products from Plant Syence are based on the patented University of California Technology. Nutri-Phite, – along with a novel seed treatment range – was designed and researched in the UK by the company and increases fertiliser efficiency to crops. They use much lower doses than conventional fertilisers and can now be used after the 15 September in Ireland, in part due to their environmental profile.
“This is great news and a real benefit to farmers as they can now legally use Nutri-Phite PGA on crops in the autumn,” explains Mr Joe Hyland, managing director, Novokem Ltd. “This helps to put the crop in a far better condition to overwinter, and with subsequent applications in the spring results have shown beneficial yield increases. In addition a Nutri-Phite PGA programme will lead to a reduction in any environmental impact from leaching, whilst growers can maximise their yield and crop quality.”
Trials, undertaken at University College, Dublin by Dr Tom McCabe have confirmed the yield benefits of applying Nutri-Phite PGA over the last two years. As Mr John Haywood, Technical Director, Plant Syence explains. “A two-spray programme made to wheat generated good yield responses:
- untreated wheat gave 8.26 tonnes per hectare
- a single application gave 8.70 tonnes per hectare
- a two spray programme gave 8.84 tonnes per hectare
Further trials are now being undertaken to evaluate the benefits of applying at the later ear emergence stage,” he said
Phosphorus is essential to drive energy transfers within the plant and improve root development, plant growth and yield. Typically phosphorus is needed at critical stages of the crop’s physiological growth. However, the major issue is not the quantity in the soil but rather the availability of phosphorus in the soil to the plant. Phosphorus availability depends on soil conditions; high pH, high calcareous soils will lock up the phosphorus making it unavailable. Environmental conditions are also influential e.g. low temperature, low organic matter, dry soils and compact waterlogged soils will all reduce availability.
Nutri-Phite PGA is unique in providing a very available form of phosphorus that will move through the leaf’s surface. The addition of PGA – a patented plant metabolite – increases nitrogen uptake and utilisation in the plant to give excellent cost-effective responses. Increased root mass and activity, stimulated by applying Nutri-Phite PGA, enables the plant to scavenge a broad range of nutrients from the soil reserves or applied fertiliser, so maximising its efficiency.
As the first 30 days in any crop’s life is the most critical, a seed treatment with Matrix should be made followed by a Nutri-Phite PGA programme will deliver the optimum results. Applications to cereal crops should be at a rate of 0.50 litres per hectare from GS12-16, with subsequent applications at stem extension and ear emergence. The organically complex formulation ensures crop safety and is compatible with most agrochemicals for tank mixing.
