  2. MINERAL slice is made up of?
    SAND SILT CLAY
  3. Describe SAND
    • The largest of the three
    • coarse hard and round
    • Dont hold nutrients
    • Help aerate the soil
  4. Describe SILT
    • Finer than sand but still gritty
    • Like Talc Powder
  5. Describe CLAY
    • Invisible to the naked eye
    • Pack tightly together
    • makes gowing vegitable difficult
    • Does not drain doesnt allow air into soil
  6. What is Loam
    THE ideal mixture of SAND 40% SILT 40% and CLAY 20%
  7. What is compost or Humus
    • Organic matter in a purposeful state
    • we add this to our beds to improve their tilth and growth of benificial micro-organisms
  8. WHAT IS NPK and What is the numbering on the bags of fertilizer
    • NPK stands for Nitrogen Phosphorus and Patassium
    • The numbers is pounds per 100 pounds of fertilizer
  9. What does Nitrogen do
    helps production of protiens and the growth of dark, green leaves. (PHOTOSYNTHESIS)
  10. What does Phosphorus do
    • promotes developement of the stem, flower,  fruit and root.
    • plant vigor
    • Disease resistance
  11. What does potassium do?
    balances nitrogen and phosphorus and is good for plant health
  12. what does Calcium do
    Builds strong cell walls and promotes growth of Beneficial Bacteria
  13. Describe the positives and negatives of Synthetic Fertilizer
    • cheaper and stronger,
    • does not contain the trace nutrients upon which plants depend.
    • can make the soil inhospitable to beneficial soil microorganisms such as fungi and
    • bacteria
  14. Describe Organic Fertilizer
    • better for the soil food web
    • increases the soils ability to retain moisture and is more sustainable

    • IDEAL ph is between 6.25 and 6.75
    • add lime to decrease acidity
  16. WHAT is Mulch

  20. Examples of winter crops
    leeks, arugula, broccoli, collards, brussel sprouts, spinach, beets, swiss chard and others.
  21. COVER CROPS (reasons)
    • help restore nitrogen to the soil
    • can return to the soil to add organic matter
    • prevent erosion and loss of top soil
    • holds nutrients that could be lost in the rain
    • break up hard pan and improve soil structure drainage and water penetration
  22. TYPES OF COVER CROPS
    • Fava Beans
    • crimson clover
    • autrian field peas
