Problem 2SE

The article referred to in Exercise 1 also considered the effect of gypsum on the electric conductivity (in dS $$\mathrm m^{-1}$$) of soil. Two types of soil were each treated with three different amounts of gypsum, with two replicates for each soil–gypsum combination. The data are presented in the following table.

a. Is there convincing evidence of an interaction between the amount of gypsum and soil type?

b. Can you conclude that the conductivity differs among the soil types?

c. Can you conclude that the conductivity differs with the amount of gypsum added?

Step 1 of 3

Soil and Water • Composition of soil ◦ organic matter ‣ plant and animal residue ‣ decay of microorganisms and chemical reactions produce humus • humus - dark amorphous organic matter ‣ mineralization - oxidation of humus to CO2, water, and minerals • reduces soil fertility ◦ water ‣ water holding capacity increases with: • greater organic content • smaller particle size ‣ Soil water - solution containing various dissolved chemicals, many of which are nutrients needed by the plant ◦ gases ‣ adequate soil aeration necessary for O2 supply and removing CO2 ‣ ideally needs large pore spaces for gas exchange ◦ organisms ‣ large number of plants, animals and microorganisms in soil ◦ 50% minerals & organic mater ◦ 50% gases, water, & living organisms ◦ mineral content classiﬁed by their diameter (size) • Soil texture and structure ◦ texture ‣ determined by percentage of clay, sand and silt (particle - size distribution) • three smallest particles in the soil • ideal = 40% sand, 40% silt, 20% clay • "yolo loam" ‣ major physical property ◦ soil structure ‣ depends on the manner in which individual soil particles are arranged ‣ sand has no structure since they are individual particles ‣ soils have a structure when the particles form aggregates • aggrega
