In surface, in heap and in silos-composters.
Surface Compost It consists of spreading on the ground (never bury, or wrap), a thin layer of organic material (less than 10 cm.), Leaving it to decompose and gradually penetrate the ground. As the natural process of incorporation into the soil occurs, new remains are spread in a continuous process. The more crumbled the faster the absorption will be but also more quickly some nutrients will be lost.
In areas like ours and in times not very hot it can be deposited without any protection. In situations of lower environmental humidity and rainfall or high temperatures it is better to cover them with a thin layer of chopped straw, grass, conifers, etc.
This composting is mainly used in orchards and serves as a soil padding that in turn prevents the evaporation of moisture and the birth of unwanted herbs and even protects from frost in cold times.
The living organisms of the soil are those that will give a good account of the scattered remains and will be responsible for incorporating them in the different levels of the soil.
Surface composting has its limitations of use in orchards, as some crops such as beans and carrots do not admit this type of fermentation well. Even so, this difficulty can be overcome with an adequate distribution of plants and of this type of composting in the garden.
Another form of surface composting consists of sowing legumes and other species (some crucifers such as mustards), then mowing or crushing them leaving them on the surface.
