  • Measuring soil physical properties to assess soil quality
    Raczkowski, C. W. (Greensboro, NC: North Carolina A&T State University, 2007)
    Soil quality is the capacity of a soil to function within ecosystem boundaries to sustain biological productivity, maintain environmental quality, and promote plant, animal and human health. A quantitative assessment of soil quality is invaluable in determining the sustainability of land management systems. Criteria for soil quality assessment are: 1) Choose indicators of soil quality based on the multiple functions of soil that maintain productivity and environmental health, 2)must include soil physical, chemical, and biological properties, and 3) give importance to those soil functions that need to be improved. This presentation emphasizes indicators of good soil physical properties and how to assess them.
  • Tillage effects on corn production and soil physical conditions
    Cassel, D. K.; Raczkowski, C. W.; Denton, H. P. (Madison, WI: Soil Science Society of America, 1995)
    This study compares four tillage methods on a highly-erodible soil in the Piedmont of the southeastern United States. The tillage methods left varying levels of surface residue: no-till (NT) had 75-87% residue coverage; 38-27% for chisel plow (CP), and 1% residue cover with moldboard plow-disk (MP) treatment. Due to decreased crusting and runoff and increased infiltration for conservation tillage practices, yields increased. Average yields were 1.23 Mg ha:1 (MP); 2.97 Mg ha:1 (NT); 2.44 Mg ha:1 (CP); and 3.69 Mg ha:1 (In-row subsoiling; one year only)
