LAST POST ON COMPOSTING?
HOORAY!!! NO MORE POSTS ON COMPOSTING? Well, maybe a mention occasionally but I promise not to bore you with dreary details.
Have you noticed my new profile photo? I am caught partway through making a portable composting bin and, in the process, reviving some satisfying carpentry skills. The bin is likely the final phase of compost bin construction for me; I set it up just last night. Here is the historical array, from left to right, the first to last.
As remarked in a previous post, a compost pile needs to be around 48 cubic feet (1.9 cubic metres) so that heat is retained while the myriads of microbes go about their work. A hot pile means compost faster. The catch is that the pile has to be kept aerated or else it will go anaerobic (smelly and not quite what one wants) which means that the heap has to be turned over regularly. A pitchfork helps a lot but a portable bin goes further to ease the work. The four sides are held together by 'hook and eye' latches. When the pile needs turning over one simply disassembles the bin, sets it up alongside the pile, and pitches the pile into the bin.
Here is the latch arrangement and you can see that the frames are lined with hardware cloth (of course, chicken wire is fine too). All this will be put to the test today (Memorial Day) when I do the actual forking over.
All told, I think it took about two days work to make the bin, no doubt faster if you have a proper workshop including a bench saw that would make the cutting out faster. I admit to enjoying the construction. The frames are quite square and exactly the same size. Why the white paint? you might well ask. Well, it was the paint I had and I thought it would turn out brownish. Ah well, at least it is weather proofed and will last longer.
Apart from the benefits of composting (great for the soil structure and worms love it), I have enjoyed finding out about the entire process. Maybe I will venture into vermiculture but worms seem to be a picky bunch and have to be treated well. As I say, Watch this space....
Expect the next post to be a Birthday Post.

COMPOSTING 201 or THE DEVIL HIMSELF
Since I joined the composting army of enthusiasts, I have not raked leaves all that much and none have left the property (except when the wind blows hard). This is because I discovered that the (non-ride) mower is a "mulching mower"; the blades have a special shape that, with the mower set up one way, shreds material and returns it to the ground as the mower proceeds. Later, the mower can be set up to collect this material, rather like a vacuum cleaner. All that is required is to remove a plastic blocking plate from the rear of the mower so that cuttings and shredded leaves can go back into the catcher bag. Then all one has to do is to empty the bag contents onto the compost heap.
Well, it is not quite that simple as you will see; there is periodic work to be done. The secret of composting lies with the work that billions of bacteria do the real work within the heap. These bacteria are already on the leaves and lawn cuttings. It is good to mix leaves and grass cuttings together as the grass has high nitrogen content and bacteria love nitrogen. To see how quickly these little fellows go to work, collect the lawn cuttings in a barrow; when it is full go away for a cup of tea or a well-earned glass of beer. When you return, place your hand into the barrel full of cuttings and feel the warmth as the bacteria go about their work.
In an earlier post I noted that I have learned how the size of the heap is important. The new pile contains old leaves from last year plus some material from last year's pile on its left which had grass cuttings as well as leaves. When making this pile, I found old leaves shed up into finer particles, which helps the bacteria no end. The new pile is much superior and actually got smoking hot despite the cool weather.
The bacteria like a moist, humid environment and it is wise to water each layer as it is added to make it a little soggy. They also like lots of air and the best way to keep the pile aerated is to turn it over each two weeks or so. Another trick is to place small tree limbs horizontally in the pile and pull them out from time to time. I like to turn the pile over but found this to be hard work when using a garden fork; good exercise however.
When Uma asked me what I would like for my birthday (at the end of this month I turn 72!), I replied that I would dearly love a pitch fork. Why wait, said she, and the next time we were at the hardware store, we got the fork. What a blessing proper tools are! How I love my new fork. Now I know why 'the Devil' is often pictured with a pitchfork...he has so much work to do, pitching those poor souls, and the right sort of fork makes the work so much easier!
Here I am, in my favorite gardening hat, good old Aussie Blundstone elastic sided boots and all! Is this the devil himself?
The great thing about compost piles is that one can put almost anything into them (except meat and fats) and, provided they are kept aerated, always smell OK. The microbes just munch it all up and turn it into stuff that, when added to the garden, does wonders for soil structure and is loved greatly by the worms, keeping the soil warm and so aiding plant growth. You can see I am a compost nut.
I made up a sieve from and old pallet and some chicken netting (left over from the 'banish woodchucks' project) and this is very useful in preparing the compost for adding to the garden and for potting. Here is some in the ancient wheel barrow. It smells fresh and sweet and has a wonderful feel to it. How could this, a year ago, have been pesky leaves and grass cuttings?
UPDATE ON ENERGY: Recent development of huge natural gas fields in Texas and Pennsylvania, along with new drilling techniques will translate into plentiful supplies of natural gas. This should enable, with carbon cap and trade, a shift away from coal fired power plants.
WAITING FOR YOUR CONCERNS ON HEALTH INSURANCE MATTERS and will see you next time.
