Revitalising liquid manure

Reference project commenced in spring 2019

20m² of liquid manure / open top + rainwater

First impressions

• Hard floating crust approx. 25 – 30cm thick
• Floating crust exhibits cracks
• Intensive smell

Changes after 4 days

It rained during this period

• Floating crust now wet
• Bubbles can be clearly seen in the cracks

Changes after another 4 days

• Floating crust splits apart in several places
• The entire floating crust moves when it is poked with an object

Changes after another 22 days

• Only a thin floating crust remains
• Easily broken up if poked
• Bubbles can be seen
• Outer temperature approximately 30°C
• Liquid manure gives off a surprisingly neutral odour

Further observations necessary

• Floating crust
• Distribution of liquid manure on the fields
• Odour during distribution
• Effects on soil, fields and vegetation
