Soil
True or False: All Soil is the same.
False: There are many types of Soil.
Planting different types of crops in a particular field every year.
This can naturally fertilize the soil!
Give 1 reason why New Plant varieties can cause problems?
-Pest attraction
-Expensive
-Concern about their effects on the environment
Herbicides are used for what?
To control weeds and kill pest plants
This is the results from deliberate actions that were not planned for or wanted...
Unintended consequences
In order to grow plants, we need this.
Soil
Yield, what is it?
The amount of useful plant parts per plant
Ex. Food in food plants
Cotton in cotton plants
Name two reasons why Farmers clear land for planting new crops?
Easier to Plant Seeds
Reduces competition between plants
Process of selecting plants with traits we want and breeding them to continue on those traits is known as?
Selective Breeding
Insecticides are used for what?
To kill insect pests
What are Organic Particles?
Pieces of a dead plant or animal matter
Irrigation is used for what?
To provide water to areas where there is not enough rain.
New plant varieties are produced to provide us with traits we need or want, what are 2 we talked about in class?
-Resistant to insects
-Resistant to cold
-Grow larger fruits
There can be problems with using herbicides can be what? Give me two examples.
-Buildup results in unhealthy soil
-Removes food from some organisms
-Can wash into rivers and streams
-Plants develop resistance
When we introduce natural predators to balance out the environment so there are fewer pests. This is known as?
Biological Control
What are Mineral Particles?
Rocks that have been ground into fine particles, allowing water to flow through them.
Fertilizer made from plant and animal waste is known as.
Organic Fertilizer
Farmers do this to move reduce packed soil which allows nutrients to mix around.
Plowing
This process allows for controlling temperature, light levels and nutrients.
Greenhouses
This process is the balancing of needs of humans with the needs of the environment. When we use technologies in an environment we need to look at all outcomes, not just the intended effects.
Environmental management
Partly decomposed materials that provides plant nutrients and absorbs water is known as what?
Humus
Fertilizer made from different types of chemicals in factories is known as.
Chemical Fertilizer
During this process, a single gene (trait coded by DNA) is inserted into the plants existing DNA.
→ This gives the plant that trait!
Genetic Engineering
Growing plants without soil. Plants are rooted in gravel and water full of nutrients is pumped in regularly.
In farming situations, many farmers will only plant one type of plant in a field. This is called a...
Monoculture
