Denitrification is express&d.as a percentage, and the normally accepted range. <br /> is,10 percent to 35 percent. Soils with higher clay content,moist soil conditions, high pH, and, <br /> organi c material denitrify about 35 percent and soils with very high-sand content and fast- <br /> percolation rates are estimated to.denitri fy'at a lower rate, about]0 percent to 15 percent.
