Combating eutrophication requires changes in land and water management in agricultural catchments and implementation of mitigation measures to reduce phosphorus (P), nitrogen (N) and suspended sediment (SS) losses. To date, such mitigation measures h

Ammonia (NH 3 ) emissions originate predominantly from manure. In outdoor pig production, excretory behav- iour creates nitrogen (N) point loads. This study examined ammonia losses from pigs on grassland at two farms by calcu- lating N field balances

Green manure crops are an important nitrogen source in organic production of vegetables. In field trials near Uppsala, Sweden, the release of nitrogen to the soil and crop from red clover mulch (Trifolium pratense L., cv. Vivi), and losses of ammonia

During the years 1992-1995, field trials were conducted at the Swedish Institute of Agricultural Engineering (JTI) to investigate the efficiency of different techniques to reduce ammonia emissions after spreading of liquid and solid manures (i.e. slu

During 1990-1993, experiments were carried out to investigate how the physicald properties of solid and liquid manures (i.e. farmyard manures and slurries) affect the performance of spreading machines, e.g. the feeding-out process and the lateral man
