Interpretive Summary:

Technical Abstract: The computer program D3 has been updated (now called D3R, for degree day decomposition of residue remaining) to estimate the amount of residue left in a field by the previous crop. At the same time D3R computes the amount of residue left on the surface or buried by different tillage implements, while continually determining the amount of decomposition occurring. D3R can compare a variety of tillage operations for their effects on the amount of crop residue on the soil surface without actually performing the tillage. It is both an educational and planning tool. One can learn the consequences of decomposition and examine the incremental effects of tillage. It is DOS based and can be run on any DOS (IBM compatible) computer.
