This is the second article discussing land use practices as reported in the 2017 US Census of Agriculture (see farmdoc daily, July 24 and August 1). Tillage is examined in this article. Tillage is of interest for several reasons, including its relationship to cost of production, yield, soil compaction, soil erosion, and water quality. Tillage system used in 2017 varies substantially by state. Main change from the 2012 Census was a shift from intensive to reduced tillage. Use of no-till increased marginally.
Census Question
The tillage practice question was asked in the context of cropland acres on the farm. The following identifying phrases were used: "no-till practices," "reduced (conservation) tillage, excluding no till practices," and "intensive (conventional) tillage practices" (bolding as in question) (Appendix B, page B-30). Instructions for the questionnaire noted, "Conservation tillage leaves 30 percent or more of the soil surface covered by crop residue after planting. Conventional tillage has 100 percent of the soil surface mixed or inverted" (Appendix B, page B-51).
