Meg,
Composting is not hard once you understand a basic rule. That is to balance the carbon items with the nitrogen items.
First lets go over a few basis.
Find a Location for the PileBig rule #1 Your pile can be built anywhere except up against a structure such as a house or fence.
As far as where to find the other items check with feed stores then your garden shops. You will find some items in feed stores that are cheaper than garden stores. Plus some items are only found in feed stores.
Rule #2 If you can place your compost pile upon a heavy plastic sheeting. This will prevent the nutrients from leach out into the ground. If you place it on ground, earthworms will come to help decompost your pile. I like the sheeting as I have a worm farm.
Add Nitrogen and Carbon Materials in Alternating Layers while adding moisture. Make sure that your layers are no more than 4-6 inches thick. Once you turn the pile the first time, the carbons and nitrogens will be mixed. The reason you layer at first is to judge how much carbon ver nitrogen you are using. Make the top layer carbon.
(More on the layering ratios later in this posting.)
Below is a chart I set up to help you understand what is carbon and nitrogen item. Plus there carbon to nitrogen ratio.
Do the math
To calculate the carbon-to-nitrogen of your compost mix, use the chart above to find the approximate percentages of carbon and nitrogen in your ingredients. Even if you're unlikely to weigh every ingredient you add to your heap, this formula will give you an idea of how to adjust the proportions of materials in your pile to get finished compost more quickly.
1. Calculate your pile's Total Carbon Value by multiplying the percent carbon of each ingredient by the number of parts (by weight) of that ingredient and then adding up the carbon totals for all the ingredients
2. Do the same for the nitrogen.
3. Divide the carbon by the nitrogen to get the C:N ratio. If it's between 25 and 35, your pile should compost beautifully. If the ratio is higher or lower than that, adjust the proportions of ingredients to bring it into the range of 25 to 35 parts carbon for each one part nitrogen.
Here's an example of how the carbon-to-nitrogen ratio works when you apply the formula to real-life amounts of real-life compost ingredients:
Starting with 50 pounds of nonlegume hay, 10 pounds of kitchen scraps, and 2 pounds of coffee grounds:
50 lbs hay x 40% C = 20 lbs. C
10 lbs kitchen scraps x 10% C = 1 lb. C
2 lbs coffee grounds x 25 % C = 0.5 lb. C
20 + 1 + 0.5 =21.5 Total Carbon Value
50 lbs hay x 1% N = 0.5 lb. N
10 lbs kitchen scraps x 1% N = 0.1 lb N
2 lbs coffee grounds x 1 % N = 0.02 lb. N
0.5 + 0.1 + 0.02 = 0.62 Total Nitrogen Value
21.5/0.62= 34.7 parts carbon to 1 part nitrogen.
Now if you are like me I hated math. So this is what I do. I go 3 parts nitrogen to 1 part carbon. i.e. A two inch layer of carbon. A six inch layer of nitrogen.
As you layer pile take some cheap beer and lightly add some to each layer. Very lightly water it. Again very lightly water each layer.
Wait 10 days. Then turn the pile inside out making sure the items that are on the outer edge this time are in the middle. If you see any items dry add water. If you see a lot of white/gray coloring add more carbon.
I always hated to wait months for mature compost. The way I have layed this out for you it will burn hot and if you turn it every 10 days, in about 90 day you should have black gold. If you use my ratio and do not turn this pile every 10 days you will burn out the pile and it will go dead. Again this will be a very hot pile. Do not allow it to go over 155 degrees. If you want a slow pile then do the math :p
This next information I know I have posted on this site before but for the life of me I cannot find it. So I will repost.Below are many formulas. The reason I have supplied you with so many is that in a given area you might not find some of the items. Or you have a need for a specific P-N-K rating. Or let’s say for example that after you did your pH test and your soil was high then you would not use wood ash which is an item used sometimes to supply the K. However, if your pH was real low then you would use it instead of , for example, greensand. At the bottom of this posting I will give you a couple of suggestion on how to feed your grass. Hopefully it is a natural grass for your area and not some import that everything wants to eat.
First let's take a look at some of the P‑K‑N ratings of just some of these items.
Blood Meal 12‑1‑1 Provides medium to rapid availability of nutrients, mainly nitrogen (N). Often used in combination with other organic fertilizers for a more complete blend. Also used in composting as starter or accelerator .
Fish Emulsion 5‑2‑2 Medium to rapid availability of nutrients, mainly nitrogen. Good for foliar feeding. Also used in composting as starter or accelerator. Often used with seaweed or kelp for liquid fertilizer.
Liquid Kelp 0.1‑0.1‑1 Medium availability of nutrients, mainly potassium. Has many micro‑nutrients.
plant growth stimulant. Aids in protecting
plants against stress. Improves
plant health and immunity to diseases. Often used with fish emulsion.
Steamed Bone Meal 1‑11‑0 Slow to medium availability. Primary nutrient is Phosphorus (P). Promotes root growth and
seed development. Often used in dry organic fertilizer blends. Used when planting bulbs as a booster.
Composted Cattle Manure 1‑1‑1 Slow to medium availability. Soil conditioner. Also used in composting as starter or accelerator.
Cottonseed Meal 7‑2‑2 Slow to medium availability. Primary nutrient is Nitrogen (N). Often used in organic fertilizer blends. Will acidify soil. Good for use around Rhododendrons, azaleas, and other acid‑loving
plants.
Alfalfa Meal 3‑1‑2 Medium availability. Good
rose food. Supplies micronutrients and horrmonal growth promoter or regulator. Generates heat as it breaks down. Also used in composting as starter or accelerator.
Greensand 0‑2‑5 Medium availability. Primary nutrient is Potassium (K). Helps promote beneficial microbial activity. More absorbent than sand (silica), but of similar consistency. Good soil conditioner and for correcting potassium deficiencies.

Meg, I could add more information, however this is a lot for anyone to take in at one time. Once have your compost ready then give me a yell and I will give you a few suggestions.
If you need to get directly to me then E-mail me: minor@tampabay.rr.com . For some reason even though I have check to recieve Email Notfication turned on I never recieve an E-mail. So if you repost to this thread E-mail me and I will check it.
