Livestock manure storage calculator

Based on the storage capacity available it calculates the number of weeks of storage available on the farm.

The calculator estimates the total amounts of slurry and dirty water produced per week and the requiring storage, based on animal type and age, areas of unroofed yards where slurry is produced, surface runoff from clean yards and silos, rainfall entering middens, lagoons and unroofed slurry tanks, and washings from milking parlours.

Under the Nitrates Action Programme for Northern Ireland dairy farmers must have at least a 22 weeks storage capacity.
