.
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. 'botanicals' or organic compounds naturally occurring in plants - animals or microbes that serve as pesticides
Natural organic pesticides
Microbial agents and biological controls
Pesticide
Organophosphates
2. 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
Cover crops
Community supported agriculture
Water logging
Salinization
3. Plants that grow for more than two years
Herbicides
Perennial species
Desertification
Rill erosion
4. Beneficial microbes (bacteria or fungi) that can be used to suppress or control pests
Microbial agents and biological controls
Natural organic pesticides
Sheet erosion
Pesticide
5. Chemical compounds that persist in the environment and retain biological activity for long times
Persistent organic pollutants
Fumigants
Economic thresholds
Pest resurgence
6. 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
Insecticides
Pesticide
Persistent organic pollutants
Terracing
7. Plowing along hill contours reduces erosion
Surface soil
Chronic effects
Contour plowing
Fungicides
8. 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
Economic thresholds
Cover crops
Terracing
Integrated pest management
9. Include cancer - birth defects - immunological problems - endometriosis - neurological problems - Parkinson's disease - and other chronic degenerative diseases
Chronic effects
Integrated pest management
Fumigants
Micorrhizal symbiosis
10. Kill fungi
Desertification
Community supported agriculture
Fungicides
Micorrhizal symbiosis
11. 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
Water logging
Organophosphates
Acute effects
Subsoil
12. Conversion of productive lands to desert
Sheet erosion
Desertification
Herbicides
Perennial species
13. Water saturation of soil that fills all air spaces and causes plant roots to die from lack of oxygen; a result of over irrigation
Mulch
Water logging
Perennial species
Biocides
14. 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
Herbicides
Integrated pest management
Inorganic pesticides
Strip farming
15. Someone who eats locally grown - seasonal food
Community supported agriculture
Persistent organic pollutants
Locavore
Acute effects
16. 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
Rill erosion
Micorrhizal symbiosis
Terracing
Chronic effects
17. Plants that can be planted immediately after harvest to hold and protect the soil
Microbial agents and biological controls
Rill erosion
Cover crops
Salinization
18. Peeling off thin layers of soil from the land surface; accomplished primarily by wind and water
Fumigants
Strip farming
Sheet erosion
Cover crops
19. A broad-spectrum poison that kills a wide range of organisms
Insecticides
Biocides
Acute effects
Locavore
20. In pest management - the point at which the cost of pest damage exceeds the costs of pest control
Locavore
Economic thresholds
Fungicides
Surface soil
21. Inorganic chemicals such as metals - acids - or bases used as pesticides
Sheet erosion
Inorganic pesticides
Fumigants
Microbial agents and biological controls
22. Protective ground cover - including both natural products and synthetic materials that protects the soil - save water - and prevent weed growth
Economic thresholds
Mulch
Strip farming
Perennial species
23. Systems - such as minimum till - conserve-till - and no-till - that preserve soil - save energy and water - and increase crop yields
Organophosphates
Reduced tillage systems
Persistent organic pollutants
Inorganic pesticides
24. Hydrocarbon molecules to which chlorine atoms are attached
Acute effects
Terracing
Chlorinated hydrocarbons
Micorrhizal symbiosis
25. 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
Surface soil
Acute effects
