is open range with soil bulk density values of about 1.3 g/cm3. Explain why the farm  field bulk density value could be higher. How would you decrease the farm field’s bulk  density on the surface? Which bulk density would you expect to be better for plant  growth? The farm field bulk density could be higher due to compaction. Compaction occurs because  agricultural equipment exerts pressure onto the soil. Compaction causes soils to have less pore  space and causes poor plant growth. Cultivation also destroys organic matter (USDA, 2008).  Organic matter has highest percentage of pore space; therefore, it greatly decreases the bulk  density ( ENSC 245 Fall Lab Manual 2018, p. 67). To decrease the farm field’s bulk density soil disturbance should be decreased and the amount of organic matter should be increased (USDA, 2008). Reducing the number of trips across the field will prevent compaction which will increase pore space and decrease bulk density. Practices that maintain or increase the amount of organic matter will also decrease bulk density. There will be better plant growth in the open range soil because it has a lower bulk density. The open range soil is not as compacted and has more organic matter. Plants struggle to grow in compacted soil and organic matter is vital for plant growth. 2. Will all the clay ever settle out of the water column?  No, because the clay particles are so small that at room temperature the particles will be excited  by the heat.  3. Hypothesize how texture might influence soil properties such as cohesiveness, shrink- swell capacity, and resistance to compaction.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
