PolyNPlus Foliars
PolyNPlus Foliars



Our range of foliar fertilisers represents a significant breakthrough in the industry's efforts to enhance Nitrogen Use Efficiency and reduce agricultural pollution.

Formulated with sulphur and selected trace elements, the PolyNPlus™ foliar nitrogen fertiliser range is a cost-effective replacement for soil-applied nitrogen during the later stages of the growing season. When PolyNPlus is used in a co-ordinated programme with soil-applied nitrogen, high yields can be achieved with less nitrogen. PolyNPlus provides a controlled release of nitrogen in a form much more easily absorbed by the crop than traditional products. Its improved leaf adhesion dramatically reduces volatilisation and leaching. See what Farmers Weekly says about PolyNPlus.

The PolyNPlus facts

  • Reduces the nitrogen needed without lowering yields.
  • Maximises Nitrogen Use Efficiency and virtually eliminates nitrate losses.
  • Uniquely PolyNPlus has been independently trialled over several years.
  • Extremely safe to apply as a foliar fertiliser from growth stage 32.
  • Can be tank-mixed with crop protection products, reducing the number of passes needed.
  • Micro-nutrients can be added to PolyNPlus to rectify any trace element deficiency.

Independent trial results

PolyNPlus has been trialled and tested over five years by leading independent research organisations NIAB and Velcourt. The trial results demonstrate the efficacy of PolyNPlus in significantly reducing the total nitrogen required for optimum crop performance while improving yields and grain protein content. For more information see a recent trials results leaflet.

Six PolyNPlus formulations

PolyNPlus Cereals 32-0-0-6 + 0.1 magnesium, manganese, zinc and copper

PolyNPlus High Sulphur 30-0-0-18 + magnesium and manganese 
Straight PolyN 35N

PolyNPlus Maize Maize needs nitrogen late in the growing cycle to aid cob fill. Soil-applied nitrogen is easily lost in dry summer conditions and slurry manures are not completely available to the plant. Foliar nitrogen fertilisers such as PolyNPlus Maize have been shown to increase weight and improve starch yields. For more information, download our PolyNPlus Maize leaflet.

Watch Joe Seels' excellent demonstration of how to apply BFS PolyNPlus to maize and his explanation of its benefits.

PolyNPlus Oilseed PolyNPlus Oilseed is used at full flowering with the standard crop protection application. It contains nitrogen and sulphur, together with the other important elements - copper, boron, magnesium, manganese, zinc and molybdenum - that are vital in the rapid growth phase of oilseed rape. It ensures efficient absorption by the canopy, longer leaf retention, essential nutrition during peak plant growth, and longer post-flowering photosynthetic activity, maximising seed yields and oil content. For more information download our PolyNPlus Oilseed leaflet.

Also available are two hybrid products, combining the benefits of PolyNPlus and Profol, with added biostimulants and micronutrients: PolyNPro and PolyNPro S. Avoid mixing manganese sulphate with the sulphur formulations of these products.
