Answer Details
The main disadvantage of mechanical tillage is the use of heavy equipment that leads to soil compaction. Soil compaction can occur when heavy machinery repeatedly moves over the soil surface, causing the soil particles to be tightly packed together. This can reduce soil porosity and limit water infiltration and air circulation, which can negatively affect plant growth and development. Therefore, mechanical tillage can have a negative impact on soil health and agricultural productivity.
