The growth in conservation tillage continues today. In fact, the percentage of no-till acres in the United States grew from 6.0% to 22.6% between 1990 and 2004 as shown in Table 1.6 [Conservation Technology Information Center (CTIC, 2004)]. Conservation tillage was used on more than 40% of all crop acres.
