A soil scientist measures that 60% of a 50-acre tested farm has degraded topsoil. If conservation practices are applied to restore 2/3 of the degraded area, how many acres will remain degraded after restoration? - Midis

Understanding the Context

Let’s break down the numbers:

• Total degraded topsoil area: 50 acres × 60% = 30 acres degraded
  
• Fraction restored through conservation practices: 2/3 of 30 acres = 20 acres
  
• Acres remaining degraded after restoration: 30 acres – 20 acres = 10 acres

Thus, after applying effective soil conservation measures—such as cover cropping, contour plowing, and no-till farming—only 10 acres of the original farm area will remain degraded.

This targeted restoration not only enhances soil fertility and water retention but also helps protect the remaining 40 acres of productive farmland. Investing in soil health isn’t just a preservation effort—it’s a strategic move toward sustainable agriculture and long-term food security.

Key Insights

FAQs:

• Why is topsoil degradation a major concern?
  Topsoil contains nutrients, organic matter, and microorganisms essential for crop growth. Its degradation leads to reduced yields, increased erosion, and higher vulnerability to drought and climate change.

• What conservation practices help restore topsoil?
  Effective methods include planting cover crops, reducing tillage, applying organic compost, practicing contour farming, and establishing agroforestry systems.

• Can degraded soil be fully restored?
  While full restoration to original fertility takes time and consistent effort, significant recovery within a few growing seasons is achievable with scientific, science-based practices.

Final Thoughts

By addressing degradation proactively, farmers can protect their land, improve resilience, and turn the tide on soil decline—one acre at a time.
