What is a significant consequence of compacted soil in agricultural practices?

Compacted soil significantly impacts agricultural practices by reducing crop yield. When soil becomes compacted, the spaces between soil particles—the pore spaces—are diminished. This leads to several problems essential for plant growth.

One major consequence of soil compaction is its effect on root development. Compacted soil creates a barrier that roots struggle to penetrate. This limits roots' access to water, nutrients, and air, which are vital for healthy plant growth. As a result, crops may experience stunted growth or failure to thrive, ultimately leading to lower yields.

Additionally, compacted soil often has poor drainage capabilities. Water cannot move through the soil as easily, which can lead to waterlogging in some areas and drought in others if rainfalls are inconsistent. This fluctuation can stress plants, further contributing to reduced yields.

In summary, the correlation between compacted soil and decreased crop yield stems from its detrimental effects on root growth, water retention, and nutrient accessibility, making this answer the most accurate reflection of the consequences of soil compaction in agricultural practices.
