.
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. 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

Biocides
Strip farming
Community supported agriculture
2. Conversion of productive lands to desert

3. The removal of thin layers of soil as little rivulets of running water gather and cut small channels in the soil
Insecticides
Rill erosion
Acute effects
Pest resurgence
4. Inorganic chemicals such as metals - acids - or bases used as pesticides
Inorganic pesticides
Natural organic pesticides
Fumigants
Strip farming
5. A broad-spectrum poison that kills a wide range of organisms

Water logging
Community supported agriculture
Desertification
Biocides
17. 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
Integrated pest management

Biocides
Terracing
18. Organic molecules to which phosphate group(s) are attached
Terracing

22. Protective ground cover - including both natural products and synthetic materials that protects the soil - save water - and prevent weed growth
Surface soil

Integrated pest management
Mulch
23. 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
