Don't risk compromising the yield or quality of your silage by cutting corners with your fertiliser programme

Balanced nutrition - use an NPKS fertiliser

Like any crop, grass needs balanced nutrition. Nitrogen, potassium, phosphate and sulphur are all required with a large demand for these macronutrients during spring growth so it is critical that sufficient quantities of all these nutrients are available for uptake when required by the plant.

  • Nitrogen drives yield. Nitrogen is the major nutrient required by grass. It is the key to achieving high dry matter yields and is often strategically used to increase production as it is needed.
  • Phosphorus promotes growth. Even though phosphorus demand is low compared to that of nitrogen its availability is essential. Phosphorus promotes rapid grass growth and is important for increasing yield. A deficiency of phosphorus can reduce nutritional quality and digestibilty.
  • Potassium requirement is high. Potassium is the nutrient required in the greatest quantity by silage swards. It has a wide-ranging role in the plant affecting nutrient uptake, photosynthesis, rate of growth and feed value.
  • Sulphur is essential for proteins. Sulphur applications reduce grass nitrate levels at harvest improving silage fermentation. Sulphur deficiency reduces nitrogen use efficiency which will reduce yield. Sulphur will improve the protein level of grass, reducing the need for supplementary feeds.


Every unit of nitrogen gives a return of 45kg of silage


Phosphorus promotes rapid growth, leaf size and plant tillering


You could lose 30% of your yield due to a shortage of potash


First cuts have a high sulphur requirement which cannot be met by slurry alone

Use a compound fertiliser

  • No segregation of nutrients. There is simply no segregation of nutrients during transport, handling or application. Because all the granules have consistent particle size and bulk density no segregation is possible, and each granule contains the exact same nutrient content.
  • No compromised spreader settings. There is no trade-off or compromise when setting the spreader, unlike when spreading a poor size matched blend when each component may require different spreader settings.
  • Spread further and more evenly. YaraMila compounds are all strong granules which can easily be spread further without the risk of shattering and dust, unlike many blends which often contain weak prills prone to shatter when they are hit by the vanes.

  • Yield increase from sulphur.  Trials results have shown an average 15% increase in yield from applying sulphur. Based on a second cut yield of 6t/ac this gives an increase of 0.9 t/ac which at £30/t = £27/ac benefit
  • Yield penalty from using a blend.  Trials have shown an average yield penalty of 3% from using poor quality blends.  Based on a second cut yield of 6t/ac this gives an increase of 0.18 t/ac which at £30/t = £5.40/ac benefit
  • Yield loss due to delay.  Trials have shown a yield loss of 6% due to an 8 day delay in application. Based on a second cut yield of 6t/ac this gives an increase of 0.36 t/ac which at £30/t = £10.80/ac benefit


Applying sulphur can give you 15% more silage


Ignoring sulphur could be costing you up to £27/ac


Applying compound fertiliser could give you 3% extra yield


An 8 day delay in application could lose you 6% yield
