Mechanized Farming
The practice of growing and raising plants or livestock for food and other human needs.
What is agriculture.
These are used to replenish the soil with nutrients.
What are fertilizers?
The percentage of global water consumption that is used for watering crops.
What is 70%?
Producing food to meet the needs of the present generation without compromising the ability to meets the needs of future generations.
What is sustainable agriculture?
A diversity of crops grown on the same plot of land.
What is a polyculture?
12 types of seeds and grains, 3 root crops, 20 fruits and vegatables, 6 mammals, 2 domesticated birds and numerous fish and other marine species.
What is the main list of our food sources?
This is a consequence of fertilizer run-off into water bodies.
What are algae blooms? (These create "dead zones" when overgrowth of algae is decomposed by bacteria using up oxygen.)
The type of irrigation that acts like a sprinkler.
What is spray irrigation? (35% of all water evaporates before it can be absorbed by plants!)
An example of this technique is growing corn, beans and squash together. The corn provides a structure for beans to grown up, beans provide nitrogen to squash, squash provides ground cover to prevent weeds.
What is companion planting?
This technique preserves the soil fertility by planting different crops on the same plot of land at different times to allow nutrients to replenish.
What is crop rotation?
A large area of land that only grows a single type of crop, with little genetic or biological diversity.
What is a monoculture?
The three nutrients most often depleted from soil.
What are nitrogen, phosphorous and potassium?
A more efficient method of irrigation in which pipes deliver water directly to the roots of plants.
What is drip irrigation?
This type of crop reduces soil erosion and water run-off from fields.
What is a cover crop?
These are 3 forms of organic fertilizers.
What are compost mulch green manure
Consequences of a monoculture:
Soil depleted of nutrients/Greater use of fertilizers Crops are more vulnerable to disease and pests/Greater use of pesticides
A chemical used to kill or control population of unwanted fungi, animals or plants.
What is a pesticide?
An organism whose genetic makeup has been altered, often containing bacterial genes to destroy insects or herbicide resistance.
What is a genetically modified organism?
Microorganisms break down organic matter, such as leaves, in soil, returning nutrients to the soil to produce this.
What is compost?
This technique uses natural predators, parasites or disease-causing organisms to reduce pests.
What is integrated pest management?
5 effects of producing food to feed a population of 7 billion:
Large areas of natural environment have been cleared Cows produce a lot of methane gas Emissions from farm machinery Nutrient runoff from the use of fertilizers Animal waste run off Over harvesting of fish
Two consequences of using pesticides are....
1) Unintentionally harming or killing non-target organisms. 2) Pests become resistant to pesticides creating new generations of pesticide resistant organisms. 3) Some pesticides do not break down and remain toxic in the ecosystem for years.
These are 2 common Bt crops. (Genetically modified crops that contain bacterial genes for destroying insects.)
What are: soybeans potatoes cotton corn
The percentage of farms in Canada that are certified organic farms, using no synthetic fertilizers, hormones, antibiotics, synthetic additives or GMOs.
What is 2%?
This organism invades the eggs of the European corn borer, an insect that damages corn, peppers, snap peas and apple crops as a means of IPM.
What is a parasitic wasp?
