Compost Heap Turning September 12th, 2012

-



Some pics of our compost heap! (pile was moved from the center to rightmost compartment of our three bin system).

Top picture is the compost heap prior to moving (with a few shovel fulls of material removed from it.) The heap has seen very little in the way of maintenance for well over a month and actually became somewhat dry. Surprisingly, there was still some warmth in the center. As you can see from the middle picture, particle size is still fairly large and there is a good number of worms and insects in the material. Bottom picture is the compost heap after transferring to the rightmost bin of the compartment (it was thoroughly moistened during this process.)

Some links on composting:

(The above link discusses oxygen, C:N ratio, moisture, temperature, particle size, time on the composting process.)

An interesting point in the above link is that moisture is needed in the pile for microbial activity, but too much reduces oxygen availability also needed by the bacteria for the decomposition process.

Will update the progress of the pile in the future.

A significant number of our neighbors live without ready access to fresh, healthy affordable food, putting them at risk for chronic health problems, including diabetes and obesity. Many individuals and organizations across the country are engaged in efforts to address this important issue, including the Vallejo People's Garden! Here we are doing our part at the Solano County Food Oasis giving out free and delicious samples of bruchetta, fresh produce, and wheatgrass!

Turning of Leaves

 Thank you volunteers Aaron and Thomas who came out to help turn the compost bins. We add compost to the raised beds and containers before each planting and use it to topdress our trees. The reason for composting are 1) it's good for the environment because you recycle kitchen and yard waste thereby reducing landfill waste 2) it adds nutrients and improves tilth to the soil 3) it introduces valuable organisms to the soil such as fungi, bacteria, and protozoa 4) it's great exercise and you can be outdoors breathing in fresh air. Lastly, it's good for the soul. Try your hand at composting. If you would like to learn how to compost, come by Sunday mornings at the Vallejo People's Garden where Ravi, our compost master can help you learn how.
