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. 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

Fungicides
Natural organic pesticides
11. Any chemical that kills - controls - drives away - or modifies the behavior of a pest
Pesticide

14. 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
Terracing
Contour plowing
Water logging
Integrated pest management
15. Plants that can be planted immediately after harvest to hold and protect the soil
Mulch
Desertification
Acute effects
Cover crops
16. Peeling off thin layers of soil from the land surface; accomplished primarily by wind and water
