Q

Subsistence Farming

A
  • Nearly all livestock and crops are used to maintain the farmer’s family (little community)
  • Low area, low amount to sell, not really reliant of machinery

Q

Irrigation terms

Over Withdrawal

A

Farm pump out of aquaifers water at fast rates compared to its recharge

Biggest aquaifer in America is Ogallala in Nebraska to texas

17
Q

Fertilizer

A

Required to replace lost orgainic matter from plants and animals; contail essential nutrients from plants

Additives to soil

18
Q

Types of Fertilizers

Synthetic

A
  • Produced commericiall with fossil fuels
  • can add any nutrient (NPK)
18
Q

Types of fertilizers

Orgainic

A

Composed of organic matter from plants and animals
(mostly Mannre or compost)

18
Q

Pros and cons

Synthetic Fertilizers

A

Pros:Easily adaptable
Targets specific crops or nutrients
Higher yield ot profit
Cons: Costly
Can cause Eutrophication

Eutrophication: excessive richness of nutrients in a lake or other body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen.

19
Q

pros and cons

Organic Fertilizers

A

Pros: Increases CEC water reatantion and adds nutrients
Cons: Takes longer time, high demand with low supply, simple but really messy

20
Q

Pesticide

A

Chemical sprayed on crops that kill need insects rodents and otehr pest that eat or damage

Canbe soild (powder) liquid or aerosol mist

21
Q

Types of Pesticides

Types of Pesticides

4 types

A

Broad: Kills many types of pest
Selecive: Targets narrow range of organizms
Persistent: Remain in environment for a lon time
Non-Persistent: Break down pest

Pros Eas response

22
Q

Pros and Cons

Pesticides

A

Pros: Easy response and efficient
Cons: Kill unwanted species,resistence overtime, runoff, and disrupts endocrine and nervous system

23
Q

GMO

A

Crops that have been scientifically manuplated for desirable traits

ex Strawberries are bigger now bc of GMOs

Gentically motified orgainsms

24
Q

Pros and Cons

GMO

A

Pros: Increases profitbaility and more crops
Cons: diversity decrease, more likly to get dieases, hard to regulate, Human perception

25
Q

Main Ag practices

Monocropping

A

Large planting of a single crops species at a time
Pros: efficent harvest and application
Cons: Low biodiversity, increase of erosion
More vulnerable to pest
lower over soil quality

26
Q

Main Ag practices

Intercropping

A

Alluring rows of crops; 2 or more species planted in the same field

27
Q

Main Ag practices

Tilling

A

Mixing and breakng upsoil to lossen roots and plants easier
Causes: increased erosion, loss of nutrients, lower WHC

WHC: Water holding capacity

28
Q

Main Ag practices

No- Till

A

Farmers do not turn soild between seasons to reduce erosion
Causes: decrease organic matter in soil and harder to plant

29
Q

Sustainable Ag practices

Crop rotation

A

Plowing parallel to natural slopes of land to prevent runoff and erosion

30
Q

Sustainable Ag practices

Agroforestry

A

Intercroppong trees with other crops to reduce erosion

31
Q

Sustainable Ag practices

Contour Plowing

A

Crop species are rotated from season to season reduce erosion and allow nutrients to replentish

32
Q

Sustainable Ag practices

Terracing

A

Cuttign flat Platforms of soil into a steep stone to prevent runoff and erosion
