Compost — the process of composting organic matter can be accelerated by alternately adding about 5 % of hydrated lime and 5 % of a nitrogenous fertiliser to layers of compost. The hydrated lime provides an alkaline environment in which the fertiliser catalyses the conversion of the compost into humus. 

Composting is another way to recycle nutrients and organic matter in sludge. The benefits from using sludge composts include increased water and nutrient holding...

Soil quality and health play an important role in sustainable agriculture Soil quality assessment provides a basic means to evaluate the sustainability of agricultural and land management systems (Doran and Parkin 1994). Soils that are healthy have homeostatic properties, within broadly set limits (Coleman et al. 1998). The application of compost can results soil quality and health because of the organic matter content and humus-producing properties. 

Compost must be cured a minimum of 21 days and organic matter must be reduced by at least 60% by weight.

The European Thematic Strategy on Soil Protection 45% of the EU soils are poor in humus and composted biowaste could be a source of organic matter for the soils.
