Soil Blocks

Elliot Coleman's soil block mix (follow the steps in the order given):
30 parts brown peat
1/8 part lime
20 parts coarse sand or perlite
3/4 part base fertilizer - equal parts colloidal (soft rock) phosphate, greensand, and blood meal
10 parts soil
20 parts compost
The lime is combined with the peat because most acid. Then sand or perlite added. Then the base fertilizer mixed in...all to distribute uniformly as possible. Add soil and compost and mix a final time.

...Mini-block recipe (no blood meal; peat & compost finely strained thru 1/4" inch mesh):
16 parts brown peat
1/4 part colloidal phosphate
1/4 part greensand (leave out if unavailable; do not substitute dried seaweed product)
4 parts compost (well-decomposed)
