The fill the pit with fresh and compact cattle manure, not containing straw, inoculated with compost prepared and sheltered by rain (but not hermetically sealed). Maria Thun has further refined this method. Mix eggshells and basalt Powder, and stay with a spade for an hour, then put in a bottomless box in the ground and leave them here for eight weeks. Use the preparation when it becomes dark brown, friable and has lost the smell of manure.
