4 cards from this section. Quick, good the night before a test.
What is gravitational potential (Ψg)?
Think about how gravity influences water flow.
Define matric potential (Ψm).
Consider the relationship between soil and water retention.
What does gravitational potential refer to?
Consider how gravity influences water flow.
True or False: Matric potential is typically a positive value.
Think about how water sticks to surfaces.
Calculate the total soil water potential given the following values: Ψg = 0.5 m, Ψm = -0.3 m, Ψo = -0.1 m.
Remember to sum the positive and negative values correctly.
Discuss how an increase in osmotic potential would affect the farming practices in an area with saline soils.
Consider how solute levels influence water absorption by plants.
