Two nutrient management treatments (sawdust or sulfuric acid application to pen surface) were compared to conventional management using 12 pens (10 steers/pen) to determine effects on performance and nitrogen losses from pens. Performance and carcass characteristics for treatments were similar to the control. The sawdust treatment retained more nitrogen in manure when removed from the pen surface and after composting. Increasing carbon by sawdust additions reduced nitrogen losses by 21%. Applying acid to the pen surface did not affect quantity of nitrogen or organic carbon conserved in manure and compost.
