Digest-It®Enhancing the nutritive value of slurry
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-effectivness on farm.
Digest-It® is approved for organic use.
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
- 20 litres/100,000 gallons of slurry
- 12.5 litres/100 cows/month
Digest-It® Trial Results
Dairy Slurry Evaluation (Mean of results from 15 UK dairy farms)Over the course of the 2009/2010 winter season, Digest-It was tested on 15 UK Dairy Farms. Average results from this extensive testing showed
