Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Someone who eats locally grown - seasonal food
Surface soil
Locavore
Perennial species
Chlorinated hydrocarbons
2. Plants that can be planted immediately after harvest to hold and protect the soil
Mulch
Acute effects
Subsoil
Cover crops
3. A process in which mineral salts accumulate in the soil - killing plants; occurs when soil in dry climates are irrigated profusely
Biocides
Pest resurgence
Strip farming
Salinization
4. Shaping the land to cerate level shelves of earth to hold water and soil; requires extensive hand labor or expensive machinery - but it enables farmers to farm very steep hillsides
Cover crops
Perennial species
Terracing
Desertification
5. Organic molecules to which phosphate group(s) are attached
Organophosphates
Acute effects
Persistent organic pollutants
Pest resurgence
6. Inorganic chemicals such as metals - acids - or bases used as pesticides
Terracing
Pest resurgence
Water logging
Inorganic pesticides
7. 'botanicals' or organic compounds naturally occurring in plants - animals or microbes that serve as pesticides
Reduced tillage systems
Natural organic pesticides
Water logging
Insecticides
8. Water saturation of soil that fills all air spaces and causes plant roots to die from lack of oxygen; a result of over irrigation
Acute effects
Surface soil
Pest resurgence
Water logging
9. A broad-spectrum poison that kills a wide range of organisms
Biocides
Sheet erosion
Fungicides
Community supported agriculture
10. Including poisoning and illnesses caused by relatively high doses and accidental exposures
Reduced tillage systems
Water logging
Acute effects
Chlorinated hydrocarbons
11. Chemicals that kill plants
Reduced tillage systems
Contour plowing
Herbicides
Pest resurgence
12. Toxic gases such as methyl bromine that are used to kill pests
Subsoil
Micorrhizal symbiosis
Herbicides
Fumigants
13. A rebound of pest populations due to acquired resistance to chemicals and nonspecific destruction to natural and competitors by broad scale pesticides
Locavore
Pest resurgence
Biocides
Microbial agents and biological controls
14. Protective ground cover - including both natural products and synthetic materials that protects the soil - save water - and prevent weed growth
Community supported agriculture
Pest resurgence
Inorganic pesticides
Mulch
15. Kill fungi
Insecticides
Fungicides
Perennial species
Pesticide
16. A program in which you make an annual contribution to a local farm in return for weekly deliveries of a 'share' of whatever the farm produces
Surface soil
Reduced tillage systems
Mulch
Community supported agriculture
17. An ecologically based pest-control strategy that relies on natural mortality factors - such as natural enemies - weather - cultural control methods - and carefully applied doses of pesticides
Integrated pest management
Surface soil
Insecticides
Chlorinated hydrocarbons
18. Plowing along hill contours reduces erosion
Contour plowing
Gully erosion
Organophosphates
Salinization
19. Beneficial microbes (bacteria or fungi) that can be used to suppress or control pests
Persistent organic pollutants
Strip farming
Terracing
Microbial agents and biological controls
20. Kill insects
Insecticides
Strip farming
Sheet erosion
Biocides
21. The first true layer of soil; layer in which organic material is mixed with mineral particles; thickness ranges from a meter of more under virgin prairie to zero in some desserts
Persistent organic pollutants
Surface soil
Subsoil
Acute effects
22. Removal of layers of soil - creating channels or ravines too large to be removed by normal tillage operations
Gully erosion
Community supported agriculture
Water logging
Integrated pest management
23. Peeling off thin layers of soil from the land surface; accomplished primarily by wind and water
Insecticides
Subsoil
Sheet erosion
Inorganic pesticides
24. A layer of soil beneath the topsoil that has a lower organic content and higher concentrations of fine mineral particles; often contains soluble compounds and clay particles carried down by percolating water
Desertification
Chlorinated hydrocarbons
Subsoil
Herbicides
25. Planting different kinds of crops alternating strips along land contours; when one crop is harvested - the other crop remains to protect the soil and prevent water from running straight down a hill
Natural organic pesticides
Mulch
Perennial species
Strip farming
26. In pest management - the point at which the cost of pest damage exceeds the costs of pest control

Integrated pest management
Economic thresholds
Mulch
27. Plants that grow for more than two years
