Silage excel - Nutrients


It is estimated that over 30% of Irish soils are deficient in sulphur which is an essential nutrient for grass growth & nitrogen efficiency. Research has found a mean grass yield response to sulphur of almost 10% at responsive sites! Land most prone to deficiencies are lighter to moderate textured soils and those that are regularly cut for silage. As there is very little sulphur available in slurry it is a key input for productive grassland. Sulphur has also been proven to help boost DM yield production, protein and grass sugar content.
DairySelect is designed to meet the demands of modern Irish grassland farmers to grow grass fast by quickly dissolving INTO the soil and not sitting ON it. DairySelect gets to more of the roots faster as there are more grains packed closer to the plant base and therefore the grass plant does not have to work as hard to access the fertiliser nutrients. Due to its hydroscopic properties DairySelect also dissolves faster into the ground and quickly provides the plant with the nutrients it needs. Other products give a slower response as they struggle to get to the plant base and as there are less of them the plant has to work hard to get the nutrients. Other products also take longer to break down particularly in dry conditions.

Features & Benefits

Features & Benefits

  • Benefits of Sulphur (S):.
  • Boosts protein & energy content in grass.
  • Increases sugar content & digestibility.
  • Improves plant growth & development.
  • Increases DM yields & nitrogen use efficiency.
Application Guidelines

Application Guidelines

As sulphur is fast acting it is best to apply it little and often. Grassland requires 15-30kg of sulphur per hectare per annum.
For silage on sulphur deficient soils, apply 20kg/ha of Sulphur per cut.
