Application of poultry litter (PL) to soil may lead to nitrogen (N) losses through ammonia (NH(3)) volatilization and to potential contamination of surface runoff with PL-derived phosphorus (P). Amending litter with acidified biochar may minimize these problems by decreasing litter pH and by retaining litter-derived P, respectively. This study evaluated the(More)
