I would like to use organic products (like bone meal, green sand, bat guano)to make a premium potting soil- similar to Fox Farms super premium potting soils- but need to know how much of each product to use. The organic products only give application amounts for linear feet (of row crops, etc). Where can I get info that suggests amounts to add to each 50 gallon batch ?. Thank you! |
Here are a couple of recipes for organic potting soil: Special potting mix 1 wheelbarrow-load sifted soil 1 wheelbarrow-load aged manure 1 wheelbarrow-load sifted old flat mix 5 shovelfuls sifted peat 2 4? pots bone meal 2 4? pots trace mineral powder 2 4? pots blood meal Organic potting mix 1 part sphagnum peat 1 part peat humus (short fiber) 1 part compost 1 part sharp sand (builder's) to every 80 qts. of this add: 1 cup greensand 1 cup colloidal phosphate 1 1/2 to 2 cups crabmeal, or blood meal 1/2 c. lime Seedling mix for soil blocks or seedling flats Sphagnum peat moss: 2 3-gal. buckets Lime: 1/4 c. Fertility mix: 1 1/2 cups Colloidal (rock) phosphate: 2 cups Greensand: 2 cups Blood meal: 2 cups Bone meal: 1/2 cup Kelp meal: 1/4 cup Vermiculite: 1 1/2 buckets Compost: 1 1/2 buckets And here's a mix for veggies: 2 bales sphagnum peat moss (3.8 or 4.0 cu.ft. bales) 1 bag coarse vermiculite (4.0 cu.ft. bags) 1 bag coarse perlite (4.0 cu.ft. bags) 6 quarts of a fertilizing mixture comprised of: 15 parts steamed bone meal 10 parts kelp meal 10 parts blood meal 5-10 parts dolomitic limestone (80-90 mesh) As you can see from the above recipes, the measurements are not critical. Be sure to mix everything thoroughly before using. Best wishes with your garden! |
