Q

Screening Test

A
  • Weigh out 100g of grain
  • Machine shakes it for 2 minutes
  • There is a sieve on top and whatever falls through the sieve is weighed out
  • That figure then is your percentage screening
  • If the final weight is less than 8%, the load can pass

Q

Hectolitre Weight

A
  • Use a chrondrometer
  • Measures the weight of the grain
  • Malting barley must have a hectolitre weight of over 63 KPH to pass.
  • Oats usually range from 52-58 KPH
  • Wheat usually ranges from 74-80 KPH
  • Anything that falls below this will be used as feed barley

Q

Protein Content Test

A
  • To determine the total protein and moisture content of whole barley by near infrared transmission
  • Distilling needs a lower protein content, therefore farmers need to be mindful of fertiliser usage, particulary nitrogen to ensure the protein is low to meet distilling criteria
  • Worth 10 euros more a tonne
  • For distilling- protein has to be lower than 8.8%
  • For brewing, the protein content has to be between 8.9% and 10.8%
  • If protein content is greater than this, the sample will be rejected and used for feed.

  • Chickweed, nettles and Mayweed
  • Spraying for cereals (4 weeks)
  • Spraying for beet (21 days)
  • Wild oats (4 weeks)
  • Speedwell: becoming resistant to herbicides
  • Chickweed is the first weed to become herbicide resistant
  • If there are a lot of resistant weeds, plant grass for 3-7 years
