Here’s a good recipe for an organic fertilizer your can make yourself. It’s a little more work than buying something pre-packaged (and probably cheaper), but I think you’ll find that the results are worth the extra effort. The bulk ingredients will last for a few years, too, making it less to worry about exactly how much you need for this season. Just mix up what you need, when you need it. That’s also why these measurements are by volume to make it easier to mix specifically for your garden size. You should plan on about 4 quarts per 100 square feet, or a handful under each transplant.

4 parts Soybean Meal (any seed meal is OK)
1 part Dolomitic Lime
1 part Bone Meal or Rock Phosphate
1/2 part Kelp Meal
1/2 part Azomite (trace elements)

This mixture results in a slow release formula which breaks down based on the activity of soil organisms. Soil temperature is also a factor. If you need a quick early season boost of nitrogen, use 1 part Blood Meal in place of 1 part Seed Meal.

This mix is based on the formula developed by Steve Solomon who is the author of Gardening When It Counts: Growing Food in Hard Times (Mother Earth News Wiser Living Series)
