U4: 4.3 Flashcards
Soil Composition and Properties
1
Q
Define soil texture
A
The percentage of sand, silt, and clay in soil (always adds up to 100%)
2
Q
Explain the relationship between soil texture and water holding capacity
A
Inverse relationship between porosity/permeability and H2O holding capacity
more porus/permeable=lower H2O holding capacity
3
Q
Identify a chemical characteristic of soil quality and explain how this characteristic relaes to soil fertility
A
pH-how a cidic (low pH) pr basic alkaline (high pH) soil is. More acidic soil= less nutrient availability therefore reducing soil fertility
