Some gardeners lay under the old board, sheet of iron and even concreted. However, it is better not to block access to the compost of earthworms. Let them participate in recycling. Therefore, it is best to use fall or straw leaves as a waste. Next is a layer of green plants: herbs, cut grass, vegetable tops (up to 20 cm), some fertilizer (5 cm) or ammonium nitrate (100 g in 1 m2 square) and "starter" (some compost and soil from the site).
You can also add pre-chopped branches of fruit trees and shrubs, bark, herbs and "spices" (lime, ash, superphosphate).
With time, the compost pile is replaced 3-4 times so that the decomposition of the organic matter becomes more uniform. Then, in the spring of next year, the compost will ripen and become a homogeneous, friable mass of dark brown with the characteristic odor of forest soil.
