The statement, "Tillage over the long-term will deplete organic matter and cause a loss of soil structure, including soil aggregation and pore space." is true.
Tillage alters soil structure by fracturing the soil, which speeds up surface runoff and soil erosion. Additionally, crop residue is reduced by tillage, which lessens the impact of pelting showers. Long-term tillage will reduce organic matter and destroy soil structure, including pore space and soil aggregation.
Without a gap from tillage, the soil structure might completely disintegrate. It is possible for soil organisms to be harmed, which would stop microbial activity. The closure of soil pores severely restricts infiltration and increases runoff. Topsoil loss starts to outweigh replenishment after a few years of repeated tillage. Due to the loss of organic matter and nutrients over time, as well as the harm done to the soil's physical qualities, the soil eventually faces a risk of yield setbacks.
