Ammosafe
Abstract
Increasing the fertilisation efficiency with liquid manure is a goal that is increasingly attracting national and international attention, both in terms of air quality (NEC Directive) and water quality (EU Water Framework Directive, EU Nitrates Directive). Stricter legal regulations but also regional surpluses of liquid manure have resulted in a massive shortage of storage space and enormous work pressure for the farmers in Styria. The aim of this project is to process liquid manure by separation and ammonia stripping, in order to use it more efficiently in terms of time and plant cultivation. The treated manure is low in nitrogen and can therefore be used on critical dates without causing groundwater pollution. Field trials are intended to confirm this thesis. The mobile treatment plant is designed to provide farmers with a more environmentally and soil friendly, as well as a socially acceptable way of spreading manure. Previous systems for manure processing were tailored almost exclusively to large farms. The process being tested in this project - independent spreading of liquid manure through appropriate slurry processing – is well adapted to smaller farms. BOKU INWE is mainly involved in the cost calcuation of this new technology at farm level.
