      abstract = {Reducing tillage and increasing soil cover can enhance  soil health. Conservation tillage, particularly no-till or  strip-till, used in conjunction with soil cover practices  (like conservation crop rotations and cover crops) can lead  to a range of soil health benefits: improved agricultural  productivity, greater drought resilience, and better  environmental outcomes. This report uses field-level data  to estimate tillage practice adoption based on soil  disturbance as measured by absence of tillage operations  (for no-till) and the Soil Tillage Intensity Rating (STIR,  for mulch till). To gauge the intensity of tillage over  time, we estimate the number of years no-till or strip-till  are used over a 4-year period. Rates of adoption for  practices that affect soil cover—including conservation  crop rotations, cover crops, double cropping, fallowing,  and residue harvest or grazing—are also estimated. The  rates at which these practices are adopted in conjunction  with no-till/strip-till are also estimated to illustrate  interactions between tillage and practices that affect soil  cover.},
