Name 2 ways a farmer can improve soil tilth and/or structure in the long term.

A soil sample plus its cylinder weighed {sd} g dry. The cylinder holding the soil has a diameter of {d} cm, a height of {h} cm and a weight of {cy} g. Assume particle density is 2.65g/cm3. Calculate the bulk density of this soil, showing the correct units. Round your answer to the nearest 0.01 (2 decimal places). Show all of your work, including units, by uploading an attachment. When typing out cubic centimeters, use the format cm^3.

How would you rate the difficulty of the concepts in this course compared with other science courses at the 200 level?

_______ soils found in _______ ecosystems are characterized by frequent periods of saturation, gleying, mottling, and/or dark organic matter accumulations.

Place the cations in order of increasing binding strength (or affinity for) soil colloid surfaces (5 = most tightly bound; 1 = least tightly bound, least flocculation)
