Fill in the following information pertaining to the nutrient cycles provided previously-
Nutrient Cycle |
Nutrient Inputs | Nutrient Losses | Is weathering a factor? (Y/N) | Is soil organic matter a factor? (Y/N) |
Name the plant-available form |
---|---|---|---|---|---|
N | |||||
P | |||||
K |
- How does CEC affect the cycling processes of P and K?
- Name one soil management strategy used to decrease the following scenarios:
- Volatilization of N:
- Runoff of P inputs from manure:
- Leaching of N, P, or K:
- How does nutrient cycling contribute to overall “soil health”?
- What are two techniques to increase soil C sequestration?
- Name two techniques to reduce P losses to water.
- Which soil, a sandy loam or clay loam, would have a larger buffering capacity for potassium? Why?
