• Square C is the middle north square in Mars Base Zero.
• Bounded on the west by square A, and separated from square A with a loose concrete block wall 2 blocks (1.25 feet) high..
• Bounded on the north by the north wall.
• Bounded on the south by square D, and separated from square D with a loose concrete block wall 2 blocks (1.25 feet) high.  On top of this wall is a 2"x6" plank to make it easier to walk down, for this is the route used to access the back area of the structure.
• Bounded on the east by square E, and separated from square E with a loose concrete block wall 2 blocks (1.25 feet) high.
• Soil bed description, from the bottom up:
• Floor
• 2 layers visqueen (plastic sheeting)
• 3" sand
• 10" soil
• Size:
• 11' 5" (3.5 m) east/west by 11' 3" (3.4 m) north/south
• 128 square feet (11.9 square meters)

• This soil bed was first filling in the summer of 1999. 
  
• 1999: It was planted this summer in turnips, carrots and wheat.
• 2000: fallow
• 2001: fallow
• 2002: Sketch of layout.  Wheat, beans, peas, carrots, radishes, broccoli, cabbage and onions.  Photo of  north half (looking NW).  Photo of the south half (looking SE).
  
• 2003: fallow
  
• 2004:  Potatoes, turnips, cabbage, wheat and spelt.

• 1999: filled with soil from the origional garden area.  It is a little low in most things, but it has a good amount of organic stuff in it so it should provide adequate nutrients.
• 2000: fallow; not too many weeds grew because it was too dry (under the roof).
• 2001: ditto.
• 2002:  It was watered with Miracle Grow fertilizer about 3 times over the summer.
• 2003: Fallow; not too many weeds grew because it was too dry (under the roof).
• 2004: Fertilized with 3 kg 8-32-16 on 5/22/04.  It was watered with Miracle Grow fertilizer (30 gallons) about 5 times over the summer.
  

Potential Future Plans:

• 2005 potatoes in the south half?
• It is getting very low on organics; the soil is no longer nice and fluffy.  Need to add in compost ASAP.
