SWS3022 Exam 3 Questions and Answers All Correct Define an acid - Answer-Any substance which increases the hydrogen ion concentration in a solution. Know the two ions considered acids in soils` - Answer-Hydrogen & Aluminum Understand how aluminum contributes to soil acidity - Answer-Aluminum has the ability to facilitate the splitting of water and react with the resulting H+. Aluminum reacts with water to bind to the hydroxide, leaving the hydrogen ion not neutralized (so lots of H+'s). ...

SWS3022 Exam 1 Questions and Answers All Correct How does texture affect overall porosity? - Answer-Finer-textured soils have greater overall porosity than coarse-textured soils. Finer soils have smaller pore spaces which increase their capillarity, and allow them to hold water and gases better. How does texture affect water and gas movement in soils? - Answer-Coarse-textured soils have bigger pore spaces and smaller total porosity, allowing water and gas to move much faster. Why are the ...
