Across
5.type of pesticide that targets insects and other invertebrates that consume crops
8.when two or more crop species are planted in the same field at the same time to promote a synergistic interaction between them
10.intercropping trees and vegetables
11.plowing and harvesting parallel to the topographic contours of the land
16.fulfills the need for food and fiber while enhancing the quality of the soil, minimizing the use of nonrenewable resources, and allowing economic viability for the farmer
17.what plants absorb through their roots
24.what does "GMO" stands for
25.the gas released by autotrophs, and what we need in order to breathe
27.type of fertilizer produced commercially and made of inorganic matter; uses fossil fuel energy to make
29.the process in which autotrophs use solar energy to convert carbon dioxide and water into sugar
31.the shift in farming methods that involved new management techniques and mechanization as well as the triad of fertilization, irrigation, and improved crop varieties.
32.the production of crops without the use of synthetic pesticides or fertilizers
33.when autotrophs are used by people as a way of providing food or money when the people care for and grow them; kind of like the word "farming"
34.another word for "autotroph" or "plant"
Down
1.type of pesticide that focuses on a narrower range of organisms
2.what a pesticide is called when it breaks down relatively rapidly
3.large planting of a single species or variety; the dominate agricultural practice in the United States
4.A facility built into the side of a frozen mountain designed to resist a wide range of possible calamities, including natural disasters and global warming; has the capacity to store up to 14.5 million seed varieties, and as of 2010, contains more than 430,000 seed varieties
6.type of agriculture that involves clearing land and using it for only a few years until the soil is depleted of nutrients
7.when crop species are switched from season to season in a field
9.type of pesticide that kills many different types of pests
12.a substance, either natural or synthetic, that kills or controls organisms that people consider pests
13.another name for the sugar made by autotrophs
14.the energy input per calorie of food produced
15.what trees and many other types of autotrophs provide for many different types of animals
17.occurs when soil remains under water for prolonged periods and impairs root growth because roots cannot get oxygen
18.what a tree or other autotroph is called when they store carbon
19.occurs when the small amounts of salts in irrigation water becomes highly concentrated on the soil surface through evaporation; these salts can eventually reach toxic levels and impede plant growth
20.agriculture designed to avoid the soil degradation that comes with conventional agricultural techniques
21.type of fertilizer composed of natural matter from plants and animals
22.increases crop growth rates or even enables crops to grow where they could not otherwise be grown
23.when trees and plant-life are completely destroyed in an area by burning, cutting down, or decomposition, and aren't replaced
26.used to make autotrophs grow better; some are made of fossil fuels
28.what a pesticide is called when they remain in the environment for a long time
30.type of pesticide that targets plant species that compete with crops
