Across
- 3. the preparation of land for growing crops
- 4. decline in soil condition
- 6. permanent covering of the soil surface with impermeable artificial materials
- 7. increase in water-soluble salts in soil
- 9. topsoil removed by wind, water, and tillage
- 10. increase in soil density and decrease in porosity that impairs soil function
Down
- 1. lowering of the soil pH by buildup of acids and leaching of bases
- 2. the layer below topsoil composed of a much lower concentration of organic matter
- 5. the upper, outermost layer of soil typically containing the highest concentration of organic matter
- 8. loss of soluble substances from the soil by solvent
