My composter, the Compact ComposTumbler still needs more browns or carbon to finish the job of composting. The compost is still very wet from all the kitchen scraps that I have put in. In other words they need more shredded leaves because that is what I have saved in bags from the fall. But they need to be shredded to compost quickly and efficiently.
Yesterday was a perfect day to shred up some leaves that I had saved from the fall. It was sunny with a nice breeze so as I emptied the bags the leaves would dry out. It was a little hot so it was a hard job. My leaf blower/shredder worked great! It is a EMax EVB200W with a 200 hp motor that we bought at Wal-Mart.
I ended up with 3 black trash bags stuffed with shredded leaves. I have already been throwing them into the composters and the compost is looking better already! I do have a bag of old peat moss but I am trying not to depend on it because it presents environmental challenges. Mike McGrath says that you need a 4 to 1 ratio for compost making. 4 of carbon or browns to 1 of greens or nitrogen. So we need lots of shredded leaves to be successful with compost unless you have some other great carbon source available. Please post other sources and ideas in the comments below. In the meantime we are good. It is amazing how many bags of leaves can fit into 1 bag after you shred them.
UPDATE: 6/1/11 I turned the composter today and looked inside. It was giving off steam when opened. The compost is much hotter. So all those shredded leaves are doing the trick. I need to get a thermometer to see how hot it is. Any good advice on compost thermometers?? Please post below.
Worm Factory Websites Advertise Worm Tea
Are you thinking of buying a Worm Factory? Several websites sell the Worm Factory, which is an older model, and the Worm Factory 360 which is the new model. These sites state that the liquid that drains into the bottom tray is worm tea. This liquid is actually leachate not worm tea. Potential buyers of the Worm Factory should have accurate information. So I would like to clear up the misunderstanding here:
Here are two examples of the erroneous comments from some of the marketing websites for the Worm Factory:
- “In a Worm Factory water will filter through the trays soaking up nutrients from the castings. The Worm Tea ends up at the base of the Worm Factory, and can be extracted from a handy spigot.”
- “Worm tea can be collected at the base of the Worm Factory. This is the waste liquid processed by the worms and it is rich in plant nutrients. A spigot at the base allows you to collect the worm tea easily. The worm tea can be diluted and used as an organic fertilizer or foliar spray.”
One Worm Factory owner emailed the Worm Factory (WF) company and posted this comment:
“After I bought my WF and following the posts here, I have e-mailed WF and commented on their description of “worm tea”. I got a reply and they admitted that the run-off is NOT WORM TEA, rather what is called LEACHATE in the vermicomposting community. The name will be changed with the next printing.” See more on this response from Worm Factory .
The Liquid from the Worm Factory is Leachate not Worm Tea
The website owners selling the Worm Factory are giving out erroneous information. The liquid in the bottom of the Worm Factory is what leaches out of the worm compost. The composition of the leachate depends on how composted the worm compost is, what food scraps are in there and what state of decomposition they are in and if any part of the factory has gone anaerobic from lack of oxygen. This leachate could actually harm your plants. See this link: Using Worm Bin Leachate.
Worm tea is made by soaking finished worm compost in water. There are many aerobic micro-organisms in worm tea. Some people aerate the tea using an aquarium bubbler and add molasses to increase the growth of the micro-organisms.
Here is an excellent discussion on the value of worm tea with differing opinions. There are over 50 comments on this thread with valuable information so you will become very educated about worm tea!
