Module 1: Principles of Agriculture Flashcards
agriculture
the science, art, or practice of cultivating the soil, producing crops, and raising livestock
- not limited to just the production of crops, but also includes the cultivation of soil, grazing of livestock, and the production of crops. Agriculture also includes the production of crops that are not consumed as food.
agriculture as a practice
techniques, skills, and methods used to raise animals, produce crops, and cultivate soil
what are examples of non-food commodities?
tobacco and cotton
what are silage ingredients?
corn leaves, corn stalks, and almost ripe corn cobs
what are some examples of institutions used for research, education, and outreach in agriculture?
International rice research institute
International potato center
International maize and wheat improvement center
International crops research institute for the semi-arid tropics
USDA agricultural research service
UF IFAS extension
what type of crop feeds the world?
grasses
what are typical inputs in food production?
land, labor, fertilizer, water, energy to run equipment, and other factors
what are typical outputs in food production?
crop products and livestock products
what happens when there is an increase in agricultural lands?
over time this results in a loss of natural ecosystems
how much of freshwater withdrawals is used for agriculture? for other uses?
70% for agriculture and 30% for other uses
what is the triple bottom line in sustainability?
economic stability, environmental quality, and social viability
what is sustainability?
- the intersection of the environment, society, and economics
- When we balance the triple bottom line, agriculture as a practice is working towards sustainability
how can agronomists be successful in their field?
need to operate under a set of rules that establishes or defines boundaries and tells them how to behave inside those boundaries: Do no harm and balance the triple bottom line
what is environmental quality?
- Environmental quality is the capacity of an ecosystem to function
- Air, water, and soil determine how well the ecosystem is functioning
how many crops are recognized by the United Nations’ Food and Agriculture Organization?
173
what crop covers the most land?
- wheat, followed by corn then rice
- wheat is the number one cereal produced based on land cultivated
what type of crop is cotton?
- a fiber crop; other examples include hemp and jute
how much of agricultural land covers our ice free land area?
37%
Is most agricultural land cropland or meadows and pastures?
Most of the global land under agricultural land cover is managed as meadows and pastures
How is agriculture used as a science?
- Used in farmer-led experiments on alternative options to chemical insecticides for cauliflower production in eastern nepal
- Tools to reduce insecticide use
How do growers meet global food demands?
By monitoring cereal yield over time
Cereals are a group of grasses that include wheat, barley, corn, and rice
rain fed crops
the crops do not receive additional inputs of water from irrigation
meadows and pastures
maintain their plant cover year after year, impacting natural biodiversity and ecosystem function in a range of ways
croplands
have undergone a complete land cover change but some natural lands may exist as a mosaic within cropland area
perennial cropland
continuous crop cover
- allows for less soil disturbance but dryer climates require more water throughout the year
annual cropland
planted and harvested annually
- have a shorter growing season which could result in tilling the soil and only needing irrigation for part of the year
