One of the compost bin suggestions: Earth Engine. This wire-and-cedar composter has the advantage of being relatively easy and inexpensive (two double bins @ $199 would cost $398).
Here's a diagram and a picture:
Another option for the compost bins would be to build our own. One fine template would be what's apparently known as a New Zealand box. I'm not sure, but I think the large pieces of wood being stored in the holding area are CCA treated. ? And this claims that is just the ticket for building the boxes. Anyway, this strongly resembles the type of compost bins we used to have.
New Zealand Box.
The New Zealand box is another simple, efficient design developed by the Auckland Humic Club of New Zealand. There are many variations of the design. The simplest is a wooden structure four feet square by four to five feet high without top or bottom. The wooden sides consist of six-inch wide by 3/4-inch thick boards. Allow at least one half inch of air space between each board so that air may penetrate the heap from all sides. The box is movable. A divider in front slides down between two posts so that when you want to empty the box, you can pull the dividers upward and take them out one by one. Two-by-fours provide the structural framework for this box. Figure 6 illustrates the construction of a variation developed by John Bartok of the University of Connecticut Extension Service.
• Eight 2" x 8" x 8'
• Three 2" x 4" x 8'
• 2 pounds 10d galvanized nails (3" long)
Note: All lumber to be CCA Pressure-treated for extended life.
1.Place two 2" x 4" x 4' long pieces on the ground 4 feet apart with the 11/2 side up. Nail four 2” x 8" x 4' long pieces across the 2" x 4"s starting at one end and leaving about 1 inch between each piece. Repeat this process to build the second side.
2. Dig four holes 12 inches deep and 4 feet apart for the legs.
3. Stand the two sides in the holes and nail four 2" x 8" x 4'3" long pieces across the back, matching the side boards.
4. Nail 2" x 4" x 33" long piece parallel to the 2" x 4" at the front of the bin on each side leaving a 2" groove to slide in the front boards which are 3'9" long. To separate the front boards, drive two nails into the edges leaving about 1" of the nail protruding.
5. To keep the top front from spreading, nail a 4' long piece of 2" x 3" across the top front 2" x 4" or build a removable retainer as shown.
6. Fill in around the posts.
7. Extensive safety reviews with CCA treated wood show no harmful effects to the environment, crops or livestock. The preservative chemicals are not absorbed by plants from contact with the soil. CCA treated wood has a useful life of 30 to 40 years.
