here is some information I found on the web too. Looks like a nice read.
If you’re in the habit of buying all sorts of liquid fertilizers and other commercial treatments for your garden, you may be happy to learn that at least two commonly discarded kitchen scraps are ideal for many of your garden plants.
You’ve heard of “liming” the garden and lawn, right? Most people buy a bag of lime (calcium carbonate) every few years and sprinkle it throughout the garden. Were you aware that eggshells are 93% calcium carbonate?
Otis the pot-bellied pig lives in the authors’ yard. A pig in the yard is a great source of fertilizer.
In addition to the calcium, the eggshells contain about 1% nitrogen, about a half-percent phosphoric acid, and other trace elements that make them a practical fertilizer. Calcium is an essential plant nutrient which plays a fundamental part in cell manufacture and growth. Most roots must have some calcium at the growing tips. Plant growth removes large quantities of calcium from the soil, and calcium must be replenished, so this is an ideal way to recycle your eggshells.
We save our eggshells in a pan in our oven. The pilot light temperature slowly dries them out. Then we crush them by hand and powder them in the blender. The powdered eggshells are then placed around fruit trees, in potted plants and roses, and broadcast throughout the vegetable garden.
You can also solve your snail problems with the help of recycled eggshells. Instead of powdering the shells, use them at the hand-crushed stage, with plenty of rough, sharp edges. Scatter the crushed shells in circles around those plants that the snails are eating. Since the shells cause discomfort to the snails, they nearly always retreat and do not cross the shell barriers. (Did you know that our California brown snails are actually escaped escargot? One method of “control” is simply to eat them—but that’s
but I have already added it.
