The following four recipes are credited to Eliot Coleman. The first
was published in the Winter 1994 issue of NOFA-NJ Organic News, in an
article by Emily Brown-Rosen. The remaining three are adapted from
Coleman's book The New Organic Grower (see Appendix 2).
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 quarts of this add:
1 cup greensand
1 cup colloidal phosphate
1 1/2 to 2 cups crab meal, or blood meal
1/2 cup lime
Blocking mix recipe
3 buckets (standard 10-quart bucket) brown peat
1/2 cup lime (mix well)
2 buckets coarse sand or perlite
3 cups base fertilizer (blood meal, colloidal phosphate, and
greensand mixed together in equal parts)
1 bucket soil
2 buckets compost
Mix all ingredients together thoroughly. Coleman does not sterilize
potting soils; he believes that damp-off and similar seedling problems
are the result of overwatering, lack of air movement, not enough sun,
over-fertilization, and other cultural mistakes.
Blocking mix recipe for larger quantities
30 units brown peat
1/8 unit lime
20 units coarse sand or perlite
3/4 unit base fertilizer (blood meal, colloidal phosphate, and
greensand mixed together in equal parts)
10 units soil
20 units compost
Mini-block recipe
16 parts brown peat
1/4 part colloidal phosphate
1/4 part greensand
4 parts compost (well decomposed)
Note: If greensand is unavailable, leave it out. Do not substitute a
dried seaweed product in this mix.
