3. From Table 3, what conclusion can you make about how soil texture affects steady-state
oils filtration rate?

Transcribed Image Text:Restricted infiltration and ponding result in poor soil aeration. This leads to poor root function, poor plant growth, nitrogen volatilization, reduced availability of nutrients for plant use, and reduced cycling of nutrients by soil organisms. The soil infiltration rate is most affected by conditions near the soil surface, and the rate can change drastically as a result of management. Infiltration is rapid through large continuous pores at the soil surface, and it slows as pores become smaller. Steady-state infiltration rates typically occur when the soil is nearly saturated. These rates are given for various textural classes in table 3. They are average values and should not be generalized for all soil types. Table 3.-Steady-state infiltration rates* (Soils are wet deep into the profile. Values should be used only for comparing to the infiltration rate of the second inch of water applied.) *Hillel, 1982. Soil texture & type Steady-state infiltration rate (in/hr) Sand >0.8 Sandy and silty soils 0.4-0.8 Loam Clayey soils 0.2-0.4 0.04-0.2 Sodic clayey soils <0.04 12 Edited from D. Steer, The Good Earth.
