Blended organic fertilizers are useful when soil fertility is in question, when starting a new garden or trying to revitalize a garden. Natural source fertilizers are slow release and continue to work as they slowly break down. Over time, once soil fertility is re-established, the need for these supplements will decline.

Steve Solomonís Formula (NPK 1:1.5:1)
Measure by volume:
4 parts seed meal (canoloa, alfalfa or soy) or fishmeal
1 part dolomite lime
1 part rock phosphate or 1/2 part bonemeal
1 part kelp meal
Blend well, but mix again before application. Work in lightly under young transplants, or sidedress along existing plants. Apply around the drip line of plants and work in gently so as not to damage the roots. Granulated fertilizer takes three to four weeks to break down before roots can access it.
Seedmeals=nitrogen source (N) for healthy leafy greens
Rock phosphate=phosphorus (P) for fruits and flowers
Kelp meal=potassium (potash) (K) for roots and overall good health
Lime counteracts soil acidity and adds calcium and magnesium
