Is it possible to replace Humus with organic manure?
In free nature without human influence, Humus is formed only in deciduous woods and untouched areas. Humus originates primarily during the decomposition of plant residues and it is mainly vegetable organic substance. Therefore, with its great content of animal excretes, animal manure cannot correspond to natural humus formation. Manure must first be humified before it can be applied in fertilization. The microbes existing in the soil are primarily oriented to the decay of pure cellulose and less to animal excrements, which leave the digestive system in an anaerobic state. This fact has been neglected by many earlier generations. Animal manure does not go through a decaying stage, rather it is only buried in the field. Applied to the soil, the anaerobic materials stay as “foreign body” for a long time. It is possible to see how minimal humus formation takes place through animal manure in soil by the following example: When 40 tons manure is applied per hectare (in light soils), after ha
