AGRICULTURE

2. a large planting of a single crop, often on the scale of hundreds or thousands of acres; monoculture plantings are typically associated with the use of large machinery and agrichemicals.
4. material that has been piled into a long row in a field; may refer to hay that is being prepared for baling, piles of compost, or other materials.
6. the integration of aquaculture (growing fish for food) and hydroponic vegetable production; these systems rely on plants to absorb fish waste from the water, which substitutes as fertilizer.
8. refers to farm and agricultural methods that employ synthetic chemicals; the opposite of organic agriculture.
10. a machine that harvests grain, threshing it in the process.

1. plants in a soilless medium (such as coco coir or perlite), typically in a greenhouse; nutrients are delivered in a liquid form.
3. a weed that has developed resistance to herbicides.
5. the study of ecological processes as they relate to food production; the goal is to develop agricultural systems that are aligned with the forces of nature, rather than using pesticides and other manmade methods to control those forces.
7. the science of agriculture, specifically as it relates to industrial-scale farming and profit maximization.
9. and implement pulled behind a tractor that chops up the surface of the soil with large metal discs, removing weeds and loosening the earth in preparation for planting.
