Home-grown grass is the lowest cost feed on livestock farms. From a nutrient perspective, we need to consider the balance between quantity and quality of grass silage.
in ammonium and nitrate forms for rapid uptake, DM yield and protein formation
available with P where soil indices are low, or no manures are being applied
water-soluble potash to drive yield and nutrient uptake
in the ideal N:S ratio of 12:1 to optimise NUE, DM yield and protein formation
ideal amount (RB209) to increase sugar content, improve fermentation and palatability and maintain the K:Na < 10:1
The benefits of including sodium in silage fertiliser were demonstrated in an independent trial by National University of Ireland, Galway in 2019.
The trial compared a Sweet Silage blend against a ‘standard’ silage CCF compound in relation to yield and forage quality.
|Parameter||24-6-12 CCF||Sweet Silage||% +/-|
|Yield, t/ha DM (2 cuts)||8.28||8.43||+1.8%|
|Crude protein (%)||23.4||24.7||+5.6%|
|ME (MJ per kg DM)||10.25||10.38||+1.3%|
The benefits of sulphur on grass quantity and quality arising from the synergies between N and S are long established and well understood, as demonstrated by the trial data (right) from Bouchard et al, Journal of Dairy Science, 1973. Yet S fertilisers are only applied to 17% of the total silage crop area (BSFP, 2019).
NUTRI-MATCH prescription fertiliser means that Sweet Silage can be formulated in any analyses or combination of nutrients to match specific soil and crop requirements.
NUTRI-MATCH enables us to add other nutrients to Sweet Silage, including: calcium, magnesium, boron, copper, iron, manganese, molybdenum, selenium or zinc.
