SVN3M Unit 2 - Sustainable Agriculture & Forests (correct answers)
Green Revolution (Third Agricultural Revolution) correct answers increase of agriculture
production worldwide

Sustainable agriculture correct answers the efficient production of safe, high-quality
agriculture products that protect the natural environment, the social, and the economic
conditions of farmers, employees and communities. Focuses on the process and
practises rather than financial outcome

soil structure correct answers the arrangement of soil particles

organic fertilizer correct answers manure & compost

synthetic fertilizer correct answers mined or produced industrially (processed)

soil microorganisms correct answers consist of insects, earthworms, fungi, bacteria
protozoa and channel nutrients and water back to plant cells, captures carbon

soil erosion correct answers loss of topsoil caused by wind, water, excessive tillage, etc

desertification correct answers process of fertile land becoming infertile, loss of nutrients
is cause by deforestation, drought, excessive tillage, erosion, etc

acidification of soil correct answers process of lowering soil pH to undesirable leves
caused by mineral weathering, acid rain, excessive fertilization, GHG's

Salinization correct answers the buildup of salts in the soil caused by road salts,
weathering of soil minerals, excessive irrigation

selective herbicides correct answers kill only certain types of plants

Non-selective herbicide correct answers kills everything

agriculture drainage correct answers water is drained by a system of subsurface plastic
tubing/clay tile, the table is lowered which allows efficient field operations and increase
yields. Cons- can move water away too quickly, easier for nutrients/chemicals to get in
waterways, changing natural habitats

irrigation correct answers three types (sprinkler, flood, drip) - the process of applying
controlled amounts of water onto croplands. Canada uses less irrigation compared to
the world.

, biodiversity correct answers a variety of life in an ecosystem

monoculture correct answers the growth of a single crop, plant, or livestock species,
variety or breed

Best Management Practices (BMPs) correct answers proactive & voluntary practices or
processes used to minimize the environmental (social, economic) impacts of an activity-
determined by a team of farmers, researchers, agribusiness professionals

Precision Agriculture correct answers using new technology to increase crop yields and
lower levels of (herbicides, pesticides, fertilizers) used. When used they gain a better
understanding of the strengths and needs of their land/livestock, make decisions on a
micro-level with different areas of the farm, make more informed decisions about
planting, managing, harvesting, application of pesticides, herbicides, antibiotics.
Resources are utilized more efficiently & maximize yields

Why is it called the Green Revolution? correct answers because of the increase in
agricultural production

How was the Green Revolution Accomplished correct answers intro of synthetic
fertilizers & pesticides, new high yield varieties of grains (wheat and rice), controlled
supply of water, mechanization

What were the results of the Green Revolution? correct answers the intense farming
with mechanization led to environmental andn human health issues.

What are the three P's? What are some of the issues in agriculture in relation to the
three Ps? correct answers Planet - soil degradation, water quantity, climate, weeds,
pests, biodiversity, energy, genetic modification. People - labour, new technology, time-
management, science, regulation, genetic modification. Profit - cost of land &
machinery/equipment, cost of quotas, market price, maximizing yields, genetic
modification

What does sustainable agriculture focus on? correct answers Focuses on the process
and practises rather than financial outcome. efficient production of safe, high-quality
agriculture products that protects the environment, social, and economic conditions of
farmers, employees, communities. An integrated system of plant and animal production
practises that over the long term - satisfy human food/fibre needs, environmental quality
+, use renewable resources, enhance quality of life for farmers/society.

There are four qualities that make for healthy soil, what are they? correct answers Good
structure (infiltration, drainage and is stable, resistant to erosion), appropriate pH levels
(support plant growth), high organic content (right amount of nutrients), living organisms
