Natural fertilizing power of limestone

Good soil must be maintained with more than tillage and irrigation methods. The soil must also have the proper acid level, a good pH balance, and sufficient nutrients in the soil to support long-term growth. The soil also benefits from having aeration and the ability to retain water. One of the simplest, most natural, and widely available substances that can accomplish this is limestone.

Limestone is a natural mineral that can help restore infertile soils. As a soil amendment, it acts as a soil conditioner and as a natural fertilizer. Who knew that a powdered version of the same stone that was used to carve the Sphinx could also be so useful in the garden!

Limestone is simply a powder that can be spread by hand or machine. In a hundred square foot area, you will need about two pounds. Limestone can also be mulched directly into the topsoil.

Limestone is very alkaline and can help balance acidic soils that have been ruined by excess nitrogen fertilizer. It can also help balance the pH levels in your soil and neutralize harmful acids.

When you deposit limestone in the soil, it also increases the bacterial activity in the soil. This is because microorganisms in the soil that may be dormant are fed and stimulated by the addition of limestone dust. Microorganisms break down limestone and make it more bioavailable to plants. This action also helps break up thatch shingles and large debris on the ground.

Limestone powder application only takes a few minutes and is easy and safe. Just sprinkle the powder where you need it and then water to help the limestone start the decomposition process. In about two weeks, most gardeners notice a healthier garden.

The EPA once conducted a study that showed that people who have gardens tend to use ten times more fertilizer than necessary. This adds unnecessary amounts of nitrogen pollution to the environment, which generally results in burning and degradation of the soil, thereby depleting its vital nutrients.

Because limestone is very rich in nitrogen, you must resist the temptation to over-apply it. Over application could cause the same type of burns that occurs with excessive use of chemical fertilizers. So keep in mind that if you are striving for an organic garden, this is the last thing you want to do.

Don’t be afraid to try something new. Try limestone as a natural fertilizer and reap the benefits.
