Ammonia Abatement by Animal Housing Techniques

Abstract

This chapter provides information on the additional costs incurred by farmers implementing measures to abate ammonia emissions from livestock housing systems, from values derived in a Spanish case study. The examples provide information on the extra costs to implement a technique, in comparison with a reference system. Calculations take into account the economic lifetime of the investment, deducting grants and including changes in performance. The information comes from an original study prepared at the request of the Spanish Ministry of Agriculture and the Environment (MAGRAMA, Comparison of ammonia emissions when using different techniques after application of slurry in Spain: summary of results 2004–2006. International conference on ammonia in agriculture: policy, science, control and implementation. Wageningen, The Netherlands, 2007). Information is provided for a variety of suitable methods for each livestock phase (Gestating Sows, Lactating Sows, Weaners and Growers-finishers). Following detailed information on each technique and its costs, a summary of the costs and emission reduction costs for this Spanish example is provided. Most effective techniques (ranked by both emissions reduction potential and maximising profitability) are listed with a discussion of complicating factors and potential caveats regarding implementation.
