Environmental Impacts
This occurs when wind or water removes the top layer of soil, reducing fertility.
Soil Erosion
This farming method reduces erosion by plowing along the natural shape of hills.
Contour plowing
Large commercial farms that produce a single crop for sale are called this.
monoculture
These crops are genetically modified to resist pests or herbicides.
GMOs (genetically modified organisms)
Farming that meets present needs without harming future production is called this.
sustainable agriculture
Farming on steep slopes without terraces often leads to this environmental problem.
Soil erosion
Planting different crops in alternating strips to reduce erosion is called this.
Strip cropping
These crops are grown mainly for sale rather than local consumption.
cash crops
This chemical is used to kill weeds in crop fields.
herbicide
Growing crops without synthetic pesticides or fertilizers is called this.
organic farming
Excess fertilizer runoff causes this environmental problem in lakes and oceans.
Eutrophication
Leaving land unplanted for a period to restore soil fertility.
Fallowing
Large-scale farming operations owned by corporations are known as this.
agribusiness
Chemicals used to kill insects that damage crops are called this.
pesticides
Planting different crops each season to maintain soil nutrients is known as this.
crop rotation
This agricultural practice causes land to become unproductive due to salt buildup from irrigation.
Salinization
This farming technique builds steps on hillsides to reduce erosion.
Terracing
This economic issue occurs when small farmers cannot compete with large industrial farms.
farm consolidation
This farming approach uses GPS, sensors, and data to maximize efficiency.
precision agriculture
This farming style integrates crops and livestock to recycle nutrients naturally.
mixed farming
Clearing forests for farmland contributes to this global environmental issue.
Deforestation
The Dust Bowl was largely caused by this combination of poor farming practices and drought.
overcultivation and drought
Countries that rely heavily on exporting crops may experience this type of economic vulnerability.
dependence on global markets
This environmental concern occurs when pests become resistant to pesticides over time.
pesticide resistance
This concept refers to the ability of a country to feed its population.
