Across
- 5. medium soil particles
- 9. an agriculture that does not cause degradation of the soil faster than it forms
- 10. the typical composition of soil in a given area
- 11. a lack of necessary nutrients required for humans and animals
- 13. man-made steps on hillsides and mountains
- 14. a pest control method that help control the organisms that threaten crop productivity via other organisms
- 17. agriculture that uses humans and animals (does not need fossil fuels) to grow crops
- 18. large soil particles
- 21. an organism which helps plants reproduce
- 24. a huge warehouse/pen of livestock/poultry that provides energy-rich food for their growth
- 25. a farming method where a "wall" of tall trees/plants is used to slow the wind through a given area
- 27. agriculture that relies on mechanized farming equipment, fossil fuels, human-made chemicals, and irrigation to grow crops
- 32. a distinct layer of soil
- 33. the process where rocks and minerals are broken down into smaller particles
- 34. the introduction of new genes into organisms to produce more valuable products via engineering
- 37. chemicals that kill organisms that utilize plants humans value
- 38. occurs when too many plants have been eaten by animals to allow for sufficient re-growth
- 39. an agriculture that does not use synthetized chemicals in the production of crops
- 40. a system comprised of wastes and remains of organisms, disintegrated rock, gases, water, nutrients and microorganisms
Down
- 1. when use of a controlled environment produces desired aquatic organisms
- 2. when any combination of various occurrences results in a loss of soil productivity (greater than ten percent)
- 3. a revolution of agriculture through new technology, crop varieties, and farming practices
- 4. a farming method where the soil is turned over before planting

- 26. the amount of a crop produced in a given area
- 28. the cross-section of the soil horizons of a given area
- 29. a farming method with the planting of different crops at the same time in a given area with various benefits depending on the crops
- 30. a farming method where crop types are alternated in a given area/field
- 31. the hard, solid rock (due to bound particles) beneath the surface materials which are made up of loose particles
- 35. a farming method where crops are planted in between main crop plantings that protect the field
- 36. the rendering of soil that no longer supports plant growth or the ecosystem
