    • Soil Solution
    • Gas Phase
    • Living Organisms
  2. perculation of water goes down why?
    Gravity
  3. aperculation of water goes up why?
    capalarity...water mocules are fuller, no membrane
  4. first layer of water chemically bonded to the clay is called...
    hydroscopic...plants can't use because bonded to clay
  5. If plant has lack of carbon, hydrogen or oxygen, what will happen?
    plant wont grow...lack of water...
  6. If a plant is not flowering or has stunted growth what does/is it lacking?
    phosphorus
  7. If plant is limp or having roots issues what is it lacking?
    Potassium
  8. If a plants leaves start turning yellow on bottom of plant what might this be a cause of?
    lack of nitrogen
  9. If a plants growth is stunted, lack of protein, amino acids...what might this be a lack of?
    sulfer
  10. What are signs of calcium definincy in a plant?
    aperical meristem dies...limp plant...lack of collenchyma cells and middle lamella...no calcium pectate to bind together
  11. If a plants leaves are turning white on top and bottom leaves are green, what might the plant be lacking?
    Iron...not getting enough chylophil...
  12. If a plant has dark green veins and yellow areas in between them, what might this be a cause of?
    Lack of magnesium
  13. C.HOPK'NS Café Mg
    • carbon
    • hydrogen
    • oxygen
    • phosphorus
    • potassium
    • nitrogen
    • sulfer
    • calcium
    • iron
    • magnesium
  14. If ph is higher than 8 it's?
    insoluable
  15. If ph is lower than 4 it's?
    soluable
  16. phosphate cycle fish bone is ?
    insoluable inorganic
  17. plants can't use hydrogen ions?
    True..only metallic
  18. Alkaline soil clay holds minerals stay with perculation.
    true
  19. non metallic + h2o = acid base
    true
  20. metalic + h2o = base
    true
  21. acid plants can't use minerals because perculation would wash out minerals.
    True
  22. weak buffer requires a?
    weak acid or weak base
  23. calcium bicarbonate is
    limestome
  24. buffered salt does not allow change
    true
  25. can't have cation exchange without clay
    true
  26. in 20/20/20 what is breakdown
    • nitrogen/leaves
    • phosphorus/flowers
    • potassium/roots
  27. strong acid + weak base =
    acid salt
  28. strong acid + strong base =
    neutral salt
  29. weak acid + strong base =
    alkaline salt
  30. weak acid + weak base =
    neutral salt
