If there was only one piece of advice I could give to improve your soil, it would be to compost. This dark, crumbly, “black gold”, is made up of decomposing organic matter. It improves your soil and keeps kitchen scraps and yard debris out of landfills. That’s 30% of household waste! So many items are compostable – more than you would probably consider. For example:
- grass clippings
- yard waste
- old potting soil
- house plants if they are not diseased
- vegetable and fruit scraps such as peelings, cores, etc.
- nut shells
- egg shells
- bread and grains
- coffee filters
- tea bags
- fresh manure
- shredded paper (no colored ink)
- used napkins and paper towels
- dryer lint if your clothing is predominately natural fiber
- natural fiber twine, string, yarn and thread
- natural fiber fabric or clothing, shredded or cut into small pieces
- animal fur
- pencil shavings
It is generally recommended that food scraps from animal products not be included with the exception of egg shells. If your compost has a secure lid that will keep animals out, you may add small scraps such as shrimp peel, dairy products, or even chicken bones that have been used for broth, if they are crumbly and soft.
For best results, the items you add to your bin should include both high carbon items, and high nitrogen items. This is referred to as browns (carbon) and greens (nitrogen). The recommended ratio is generally 25 – 30 parts carbon to 1 part nitrogen. Generally, drier items such as leaves, newspaper, straw, and natural fibers are considered browns, and wetter items such as kitchen scraps, grass clippings, and fresh manure are considered greens. Having a proper balance will provide the needed ingredients so that composition occurs relatively quickly. If you do not have the perfect balance, don’t fret, and add what you have available. If you find that your compost is very smelly, try to add more browns. If leaves are not available, add some shredded newspaper. On the other hand, if your compost seems to be just sitting there and not decomposing, then greens are what is needed. Keeping your compost as wet as a sponge which has been wrung out is about right. If it is dry, just add water. Everything soon begins to rot as bacteria, fungi, protozoans and earthworms each do their part. Turning your compost monthly will increase aerobic activity and speed up the process, although it is better not to turn the pile during cold, winter weather to help maintain the heat in the pile.
There are many types of bins available for purchase, but they tend to be pricey. Simple, inexpensive bins are easy to make. A garbage can with the bottom removed will work just fine. A 10′ length of galvanized chicken wire formed into a circle is another simple method. More ideas may be found here.
Compost may be used as a top dressing, or dug into the top few inches of soil. There never seems to be enough to go around, so I use it where it will give the most benefit. I add a large handful to each hole as I am planting my tomatoes, peppers and other vegetables. I top dress plants such as clematis, peonies and hydrangea. And I always save some for any new plant that I am adding to my landscape. As a young gardener, no money was available for soil testing. I just kept adding compost to my garden year after year. When I finally had my garden soil tested, the results showed that it needed no further amending!
