Roman Ferro BRAE 331 1/19/11 PS#3 1. What types of plant nutrients are found on the exchange sites? Nutrients with positive charges, such as NH4+, Ca+, and K+. 2. Explain the relative ease of movement of each to the following ions as water moves down through the root zone during an irrigation: a. Nitrate: Will leach out due to it being a negatively charged ion. The soil is also negatively charged so it will not bond with it. b. Calcium: Is positive charged and will bond with the negative soil. Irrigating will not cause it to move through the soil. c. Phosphate: Is negatively charged, but it will bond with other chemicals in the soil and will not leach out. d. Potassium: Is positively charged an will bond with the negatively charged soil, allowing it to not leach out with irrigation of water. 3. What are the irrigation factors that influence soil surface structure? Sprinkler irrigation with large droplets, furrow irrigation, and irrigation with pure water. 4. Given: A glass capillary tube.
