(10 pts) Describe why it is impоrtаnt tо prоperly mаnаge soil pH in agroecosystems to ensure optimal nutrient management. Compare the effects of acidic vs. alkaline soils on nutrient availability, excluding elements that are not essential nutrients for crop growth (e.g., you can discuss P, B and/or K, but do not discuss elements like Pb or Cd). (10 pts) Acidic soils also have other deleterious effects on nutrient management – describe one effect on the cycling of an element in soils that is not an essential nutrient (i.e., an element that never provides direct nutrition to plants and is known to damage plant roots, among other impacts), and how a low pH directly impacts soil microbes. In addition, briefly describe how you can improve the pH of an acidic soil.
