Hello my name is William David Underwood and I am the proprietor of Muckfast. Having been in the Agricultural Contracting business for many years I heard of the problems of slurry/dirty water disposal faced by farmers. After 12 months of research looking into the requirements of farmers and the slurry equipment available I set up an umbilical injection system in 1993.

Over the years my business has expanded, and the set-up now consists of:-

• Veenhuis Umbilical Injector - Grassland model featuring 16 injectors
• Groundhog Umbilical Injector - Primarily used on stubble in the Autumn
• 1400m of piping and Wangen Pump
• In Cab Computer and Flow Meter which records the forward speed of the tractor, the rate of application, the total amount applied and the total area covered.
• Slurry testing for Nitrogen content - Advice can be given on the amount of Nitrogen applied to the land so fertiliser application rates can be adjusted accordingly.
• 9500 litre Veenhuis tanker mounted with Veenhuis Umbilical Injector.
• Abbey Dual Muck Spreader

I am currently involved in a 3 year trial with ADAS/IGER where my work will be carefully monitored to evaluate ammonia losses into the atmosphere during and after slurry injection.
