Digest-IT

A Biological Slurry and Digestate Additive

Designed to increase nutrient recovery from slurry while also reducing ammonia emissions.

How Does DIGEST-IT® Work?

DIGEST-IT® provides a rich food for microbes as well as dormant aerobic bacteria species that are able to feed on and break down the organic matter in the slurry and use the ammonia gas as a source of nitrogen to grow, thus turning it into microbial nitrogen

Benefits of DIGEST-IT®

In the Tank:

• Reduces time required to agitate and pump slurry.
• Less smell from fresh slurry when agitating or spreading.
• Converts solids into plant-available liquid nutrients.
• Reduces surface crusting.
  
  

For Slurry Storage:

• 80% reduction in ammonia losses, resulting in less smell from slurry when agitating or spreading.
• In trials over a 13-week period, the mean ammonia concentration level for untreated slurry was 20.9ppm compared to 4.2ppm for the DIGEST-IT® treated slurry – an 80% reduction.
• Anaerobic bacteria compost solids into plant-available liquid nutrients.
• 29% reduction in oven dry solids, reducing surface crusting and the time required to agitate slurry
  
  

In the Field:

• DIGEST-IT® treated slurry grows more, better quality grass.
• DIGEST-IT® treated slurry reduces odour when spreading.
• DIGEST-IT® treated slurry improves soil health by supplying ‘good’ microbes to the soil.
• DIGEST-IT® treated slurry is kinder to the soil organisms living in your soil, including worms.
• DIGEST-IT® treated slurry has a lower Biochemical Oxygen Demand (BOD) than untreated slurry

“Slurry is easier mixed when it is treated with DIGEST-IT®. We definitely see a reduced smell, the worms are surviving in the ground, we are growing more grass and the cows are able to graze in a rotation system.”

- Clive Reid, Dairy Farmer

Application Guidance

When best to apply:

• Apply to lagoons ahead of filling.
• 12 weeks before application.
• Does the inclusion rate vary depending on what it’s mixed with? (e.g. slurry / digestate) No, the application rate stays the same regardless.
