Activity 1 – Water Holding Capacity & Capillary Action of Soil 1. Grain size and the amount of air space between particles. 2. Water-holding capacity determines the amount of water a soil is capable of holding. Since water is a necessity of any agricultural endeavor it is important for a soil to have a good water holding capacity. 3. We’d add humus because it has the highest water-holding capacity. 4. It would benefit plants in a dry climate because it could easily take groundwater

of the centrifuge increases. The G-force increases as the speed of the centrifuge increases. Which is likely the best speed to separate the components of this soil sample? Why? The best speed to seperate the components of this soil sample would be 5000 rpm because there are only two layers so the soil is more separate in that speed. Describe in which layers you are likely to find the organic matter‚ gravel‚ sand‚ silt‚ and clay at the following speeds:
