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. Plowing along hill contours reduces erosion
Integrated pest management
Locavore
Economic thresholds
Contour plowing
2. Including poisoning and illnesses caused by relatively high doses and accidental exposures
Contour plowing
Mulch
Perennial species
Acute effects
3. Toxic gases such as methyl bromine that are used to kill pests
Fumigants
Herbicides
Terracing
Gully erosion
4. The removal of thin layers of soil as little rivulets of running water gather and cut small channels in the soil
Rill erosion
Natural organic pesticides
Insecticides
Fumigants
5. An association between the roots of most plant species and certain fungi. The plant provides organic compounds to the fungus - while the fungus provides water and nutrients to the plant
Micorrhizal symbiosis
Microbial agents and biological controls
Chronic effects
Subsoil
6. Plants that can be planted immediately after harvest to hold and protect the soil
Fumigants
Community supported agriculture
Cover crops
Chlorinated hydrocarbons
7. Chemical compounds that persist in the environment and retain biological activity for long times
Water logging
Surface soil
Persistent organic pollutants
Pesticide
8. Someone who eats locally grown - seasonal food
Locavore
Organophosphates
Mulch
Desertification
9. Hydrocarbon molecules to which chlorine atoms are attached
Mulch
Chlorinated hydrocarbons
Fungicides
Subsoil
10. 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
Organophosphates
Community supported agriculture
Fumigants
Pest resurgence
11. Systems - such as minimum till - conserve-till - and no-till - that preserve soil - save energy and water - and increase crop yields
Perennial species
Subsoil
Reduced tillage systems
Gully erosion
12. Organic molecules to which phosphate group(s) are attached
Organophosphates
Sheet erosion
Pest resurgence
Water logging
13. 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
Surface soil
Desertification
Subsoil
Terracing
14. A broad-spectrum poison that kills a wide range of organisms
Contour plowing
Gully erosion
Biocides
Reduced tillage systems
15. 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
Acute effects
Integrated pest management
Strip farming
Chlorinated hydrocarbons
16. Conversion of productive lands to desert
Sheet erosion
Desertification
Surface soil
Salinization
17. In pest management - the point at which the cost of pest damage exceeds the costs of pest control
Subsoil
Acute effects
Economic thresholds
Contour plowing
18. Removal of layers of soil - creating channels or ravines too large to be removed by normal tillage operations
Subsoil
Biocides
Gully erosion
Contour plowing
19. Inorganic chemicals such as metals - acids - or bases used as pesticides
Gully erosion
Persistent organic pollutants
Inorganic pesticides
Reduced tillage systems
20. Beneficial microbes (bacteria or fungi) that can be used to suppress or control pests
Organophosphates
Sheet erosion
Contour plowing
Microbial agents and biological controls
21. Include cancer - birth defects - immunological problems - endometriosis - neurological problems - Parkinson's disease - and other chronic degenerative diseases
Chronic effects
Gully erosion
Organophosphates
Surface soil
22. 'botanicals' or organic compounds naturally occurring in plants - animals or microbes that serve as pesticides
Strip farming
Persistent organic pollutants
Economic thresholds
Natural organic pesticides
23. Kill insects
Fumigants
Biocides
Microbial agents and biological controls
Insecticides
24. Plants that grow for more than two years
Persistent organic pollutants
Desertification
Surface soil
Perennial species
25. Protective ground cover - including both natural products and synthetic materials that protects the soil - save water - and prevent weed growth
Mulch
Rill erosion
Chlorinated hydrocarbons
Reduced tillage systems
26. Chemicals that kill plants
Community supported agriculture
Organophosphates
Herbicides
Perennial species
27. Any chemical that kills - controls - drives away - or modifies the behavior of a pest
Pesticide
Integrated pest management
Cover crops
Subsoil
28. 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
Contour plowing
Herbicides
Desertification
Integrated pest management
29. Kill fungi
Fungicides
Mulch
