Making Homemade Organic Fertilizer

Homemade organic fertilizer can provide your garden with natural nutrients for several years.  More people are turning to organic fertilizers for a more natural choice to feeding their gardens.

Compost and natural organic matter takes time to break down and delivers vital nutrients and organic matter to your growing plants and enriches your soils rather than depleting them.

Chemical fertilizers are like taking a shot of adrenaline. It acts fast and then is gone leaving the plants stressed and vulnerable to pests and diseases. Chemical fertilizers do not always provide the trace minerals plants need and leave the soils depleted.

Most garden fertilizers deliver nitrogen phosphorus and potassium but plants need calcium and magnesium as well as trace minerals. Organic fertilizers should strive to provide all the nutrients needed to keep plants and soils healthy.

Some good sources of organic nutrition are listed here. Most of the products can be found at your local nurseries as the public demand for organic choices increase. If your local nurseries don’t carry these products ask for them.

Your local feed store is another good source of these natural products. Most can be bought in 25 to 50 pound bags which save money. The nurseries tend to carry them in small units for those who only need small amounts for your vegetable garden.

If you have a no-till or mulched garden the fertilizer can be sprinkled on top of the mulch. Since organic matter is needed to break down the natural fertilizers making them available to the vegetable plants, mulching the garden is a natural and easy way to provide it. At the same time the mulch preserves moisture and helps in weed control.
