Separator kits that remove the solid element of slurry could help farmers maintain storage capacity during times of high rainfall.
Stallkamp’s new system – the PSS 2.2-400 Compress – uses a screw pump to suck slurry through a contaminant filter, removing foreign objects such as stones and bits of rubber mat.
The filtered slurry is then fed through a separator with a 0.5mm or 1mm screen that removes the dry matter, leaving just the liquid. The dry matter element can be sold to arable growers, or used as an additional bedding material, says Tramspread UK.
The liquid only loses approximately 10% of the N, P and K values, so is still a valuable grassland input.
