Digest-It

What is Digest-It ®?

Digest-It ® is a liquid biological composting agent, containing aerobic bacteria, enzymes and nutrients, which is used to aerobically compost slurry. By doing so, Digest-It ® has been proven to improve the fertiliser nutrient value of slurry, resulting in higher DM yields and improved cost-effectiveness on farm.

The Benefits of Digest-It® include:

  • Reduce energy required to agitate tank
  • Increase nutrient availability and value of slurry
  • Grow more grass
  • Break down crusts and solids in tank
  • Reduce odour
  • Approved for organic use

Application rate of Digest-It®:

  • 1 litre/22m3 slurry
    or
  • 20 litres/100,000 gallons of slurry
    or
  • 12.5 litres/100 cows/month
