Abstract: Soil compaction is a threat to crop yield, but mechanical decompaction operations increase soil degradation risk and crop costs. The decision about soil management practices that minimize yield loss depends on the impact of soil compaction on crop yield. However, the relationship between soil compaction and crop yield is affected by rainfall pattern, which changes over the years. Long-term effect of soil compaction in crop yield is wide unknown, and fill this gap is crucial for adjust soil management to improve soil conservation and increase crop yield.
