Soil compaction
The process of reducing soil porosity due to mechanical pressure, which leads to increased density, restricted root growth, and impaired water and air movement within the soil profile.

Soil compaction occurs when soil particles are pressed together by heavy machinery or repeated traffic, drastically reducing the volume of pores. This physical change inhibits the exchange of gases and limits the vertical movement of water, creating an environment unfavorable for plant life.
To mitigate these effects, farmers use controlled traffic farming, low-pressure tires, and reduced tillage systems. It is crucial to schedule field operations when soil moisture levels are optimal to prevent excessive rutting and deep-layer deformation.
A common mistake is operating machinery on saturated soil, which accelerates the formation of a compacted hardpan layer. Neglecting to address this issue hinders nutrient uptake and long-term soil productivity, ultimately leading to significant yield losses.
