Explanation:
Detailed explanation-1: -A hardpan forms when the tillage implement presses soil directly below it together, forming a compacted layer. Deep compaction occurs further down in the soil profile and is caused by excessive weight on soil, particularly when soil is wet. It can be hard to break up soil once deep compaction occurs.
Detailed explanation-2: -Soil compaction can lead to: poor root growth-which reduces crop yield through poor water and nutrient uptake. difficulties with soil cultivation and seedbed preparation. a decrease in water entering the soil either as rain or irrigation.
