Take control of silage yield and quality

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.
