Questions and Answers

What is soil conservation?

  • The practice of removing soil to create a flat surface for construction.
  • The prevention of soil loss due to erosion or reduced fertility caused by over-usage, chemical contamination, acidification, or salinization. (correct)
  • The process of compacting soil to increase its stability.
  • The process of adding nutrients to soil to improve crop yield.

    • Which of the following is a technique for improving soil conservation?

  • Overgrazing
  • Crop rotation (correct)
  • Deforestation
  • Urbanization

    • What is contour plowing?

  • Plowing in a zigzag pattern to increase soil porosity.
  • Plowing along the contours of a slope to prevent soil erosion. (correct)
  • Plowing in a circular pattern to conserve soil moisture.

    Study Notes

    Soil conservation is the prevention of soil loss due to erosion or reduced fertility caused by over-usage, chemical contamination, acidification, or salinization. Techniques for improved soil conservation include crop rotation, conservation tillage, cover crops, and planted windbreaks. Soil conservation farming involves no-till farming, green manures, and other soil-enhancing practices, which make it hard for soils to be equalized. Contour plowing, terracing, and keyline design are some of the popular techniques to conserve soil. Salinity management, reducing the use of pesticides, and planting species that can tolerate saline conditions can be used to lower water tables and reduce the rate of capillary and evaporative enrichment of surface salts. Soil organisms such as earthworms, nematodes, mycorrhiza, and bacteria play a crucial role in improving soil porosity and nutrient availability. Each one percent increase in soil organic matter helps soil hold 20,000 gallons more water per acre. Mineralization can combat mineral depletion, and flooding can rejuvenate soil chemistry through mineralization.
