Physical Properties of Soil

Match the following

• Physcial Properties

• Several characteristics that a grower can see or feel in soil.

• Particle Density

• Soil texture that feels gritty

• Sand

• Soil Texture that feels sticky

• Clay

• Most fundamental soil property.

• Texture

• Density of solid particles ONLY is called..

Why does sand have the least surface area compared to clay?

• Clay has medium particle size and holds more particles per sand grain. Therefore it has more surface area.

• Clay has small particle size and holds more particles per sand grain. Therefore it has more surface area.

• Silt has Large particle size and holds less particles per sand grain. Therefore it has more surface area.

• Clay has Small particle size and holds less particles per sand grain. Therefore it has more surface area.

Match the following

• Sticky & Small

• Clay

• Gritty & Large

• Silt

• Silky & Medium

• Sand

Advantage or having course soils in a feild are?

• They hold water longer

• They allow for restricted air flow

• Feilds dry out faster

• We need to Irrigate more fequently

Disadvantage to having course soils in a feild are?

• They are always waterlogged

• They allow for restricted air flow

• Feilds dry out faster

• We need to Irrigate more fequently

True or False: Having peds in the soil allows for larger holding cappacity of air and water.

• True

• False: It decreases the wter holding cappacity.

• False: It only increases the water holding

All the factors that make up tilth are: ​ (a)   ​ (b)   ​ (c)   ​ (d)   ​

• Texture
• Structure
• Permiability
• Consistence
• Nutrients
• Tillage
• Sunlight
• Soil Color

How can compatcion impact the growing enviroment of plants?

• Reduce Porosity & Bulk Density

• Makes water movement and plant growth easy

• Makes water movement and plant growth hard

• Increase Porosity & Bulk Density.
