NIAB TAG also conducted a series of trials which showed that PolyNPlus had positive effects on grain yield and protein content in KWS Zyatt winter milling wheat (Graph 2 and Graph 3). The data from the trials shows that: • Provided sufficient soil-applied nitrogen is used at the start of the growing season, two foliar applications of PolyNPlus can replace the third tranche of soilapplied nitrogen, resulting in higher yields with less total nitrogen. • It potentially will increase the protein in the grain of milling wheat which improves the baking quality of flour such as dough elasticity.

• It is safe to apply direct to the leaf. • It is particularly useful during dry spells when a crop’s uptake of soilapplied nitrogen is low. Further trials are being undertaken in 2020 to determine how farmers can use the product to maximum effect. BFS Fertiliser Services managing director, Rosalind Platt, said: “We are delighted that our breakthrough PolyNPlus range of foliar nitrogen

anticipates the NFU’s drive to reduce the farming industry’s greenhouse gas emissions to net zero by 2040. The data from independent tests on PolyNPlus demonstrates clearly that less nitrogen is needed than in standard farm practice, at the same time as yields and protein content are improved. Uniquely, at BFS we can also tailor the product to add individual farmers’ specific trace element requirements,” she commented. FG

Don’t use Monceren this season Bayer is maintaining its previous advice not to use the potato tuber treatment, Monceren (pencycuron) this season after the European Commission followed through on proposals to set a new maximum residue limit (MRL). The Commission’s proposal of a lower limit of 0.01mg/kg is expected to become official by June 2020. A transitional period of up to six months is likely to follow to allow treated crops in store to be cleared after which any imported or treated crop will have to meet the new MRL. While this means Monceren could still be applied during spring 2020, the potatoes produced from the treated tubers would

need to be sold by the end of the unconfirmed transitional period. Therefore to minimise the risk of exceedances of the MRL, Bayer is continuing to advise growers not to apply the product this spring on any crops, either entirely or in part, that will be used in food or feed. Seed growers who cannot be certain that part or all of their crop will not be diverted to these markets should also consider using an alternative product such as Emesto Prime (penflufen). Bayer says that it will take back unopened and undamaged stocks of Monceren; for returns, growers should contact the distributor who sold the Monceren DS. FG

To test the efficacy of PolyNPlus in 2019, Velcourt farm managers and agronomists conducted a trial on Crusoe winter wheat in Casthorpe, Lincolnshire to measure the effects of different application rates and timings between soil-applied nitrogen only, and soil-applied with PolyNPlus. The study (Table and Graph 1 below) showed that, using PolyNPlus, significantly lower levels of nitrogen were required to produce comparable or better yields.

Yield (t/ha)

Formulated with ureic polymers, PolyNPlus eliminates nitrate losses and minimises ammonia emissions. When applied in a co-ordinated programme, with soil-applied nitrogen, the result is high yields and increased grain protein content using less nitrogen than in standard farm practice. In addition, as PolyNPlus can be tank-mixed with crop protection products, it reduces the number of passes needed, saving time and application costs. These benefits also chime with the NFU’s vision of the farming industry: “working smarter to use fewer inputs”.

Crop nutrition specialist, BFS Fertiliser Services has released new trials data which reinforces the efficacy of PolyNPlus, its foliar fertiliser, in significantly reducing the total nitrogen required for optimum crop performance. Reducing emissions to enhance productivity is a key element of the NFU’s vision for the farming industry; ‘Achieving Net Zero: Farming’s 2040 Goals’, says the company.
