Cu, Fe, Mn, Mo, and Zn 2. Why are plant available concentrations of metals much lower than total soil concentrations in Montana and Wyoming? [ ] a. Arid conditions [ ] b. High soil pH [ ] c. Limited fertilization [ ] d. Few industries 3. Why are micronutrients called micronutrients? [ ] a. They have low atomic weights [ ] c. They aren’t used very often [ ] b. They exist in lower concentrations in soil [ ] d. They’re needed in lower amounts by the plant 4. Which of the following crops would you expect to have the smallest yield loss in a Zn-deficient soil? [ ] a. Barley [ ] b. Winter wheat [ ] c. Oat [ ] d. Durum wheat 5. What is meant by ‘chelation’? [ ] a. The binding of lime to metals [ ] c. Complexation of organics with metals [ ] b.

[ ] a. 5.5 [ ] b. 6.5 [ ] c. 7.5 [ ] d. 8.5 7. Is leaching generally a concern with the metal micronutrients, and why or why not? [ ] a. Yes, because they’re toxic [ ] c. No, because they bind strongly to soil [ ] b. Yes, because they’re mobile [ ] d. No, because rainfall is never high enough 8.

Soil applied suspensions 18. If ferrous sulfate and iron oxalate were the same price, which one would you apply, and why? [ ] a. Iron oxalate because it has higher solubility and Fe content [ ] b. Iron oxalate because the carbon in oxalate will be useful for photosynthesis [ ] c. Ferrous sulfate because it has higher solubility and Fe content [ ] d. Ferrous sulfate because soils

FAQs

How should answers be marked and what must be submitted to take the quiz?
