Unit 2: Applying Ecological Principles
SUSTAINABLE CROP PRODUCTION
|
Grasses and legumes cover the land and improve soil and water quality. (Rich Sanders, USDA NRCS) |
What are the essential environmental requirements for plant growth? Think about that question, write down your list, then click on the heading below to check your answers:
-
light
-
water
-
temperatures that support physiological processes
-
space for root and vegetation development
-
oxygen
-
carbon dioxide
-
mineral elements (nutrients)
These requirements for plant growth are clearly related to the environmental factors determined by place and location (see Ecological Principle 1). However, human activity and land management practices also affect these conditions. |
