Composting the Final Chapter

I have heard people say you should put your compost pile in a depression. The theory behind this is that your nutrients will not leach out. The problem with this is that if the water does not drain out your will have a smelly aerobic mess. It is better to put your compost pile where your garden is going to be. Your compost pile should be placed on level ground.

Another approach is to have your compost pile several layers off the ground. This creates airflow by creating channels below the pile. You can use pallets to prop the pile up, But if you have the pile to high the air beneath it will cool the pile down and slow decomposition. Also with this method microorganisms from the ground will not be able to reach the pile.

Do not put you compost pile on a concrete slab. While it prevents nutrients from being leached out into the ground, it empedes aeroation and does not let microials or worms contact the pile. also do not line the floor of the compost pile with plastic to avoid leaching. you will only cut off oxygen supply to the pile, slowing decomp and killing microbes.

Your compost pile should measure 1 cubic yard at least.

Nevery make your compost pile wider or taller then 5-6 feet or your piles center will not have enough air circulation and will become aerobic. Try and keep your pile between 4-6 feet tall.

Always alternate your layers between dry and green stuff. make the layers 6 inch thick for best results. A good example of layering is 6 inch layer of veg or greenstuff, 6 inch manure, a thin layer of soil or finished compost, water then repeat. If you do not want to use animal matter you can instead use rock phosphate.

Your pile will shrink 20-60% depending on material added you can add more material if you like to rebuild pile height.

Aeroation is very important when composting add 2 to 4 inches of sunflower stalks to the baseof a compost pile will provide good air channels.

Another good way to provide good aeroation is to build your pile around ventilating stacks. There are several ways to make the stacks. You can use perforated drainage pipe. You can bundle up corn stalks into cylinders or twist chicken wire into cylinders. You mount the vent stalks straight up and down.

Once your pile is built you can try poking holes through it using a long metal pipe.

You want your compost pile to be between 60-40% moisture content. Basically the material in the pile needs to be wet in the consistancy of a wet wrong spounge.

So one of the biggest problems you will have with your pile is getting the entire pile wet and having no dry spots. Poking holes in the pile helps not only with the aeroation but also helps the entire pile get moisture. Turning your pile throughly also helps with this. also getting your pile wet as you are buliding the layer helps with this.

Thinsg like hay, straw, saw dust, moss and corn cobs should be pre-moistened before adding to the pile.

Rain water is very good for compost pile. Rain water picks up lots of oxygen, minerals, andmicro-organisms on teh way down. You can dish the top of your pile to collect rainwater.

The ph in your ple should be between 6 and 7. The best time to check the ph is before adding to soil. If your plants like it more acidic like blue berries you would add more oak leaves to your pile.

A compost pile that is healthy will maturally neutrilize itself.

Compost is not food it is more like a vitamin boost for your plants. Almost all compost has a very low NPK. Most grdeners add nutrients with compost when applying to garden.
