The organic material in compost acts as soil conditioner. It also improves the structure and water holding capacity of sandy soils and adds structure and permeability to clay soils. Composted excreta, on its own or combined with other biodegradable material, enhances the fertility of topsoil.''' Composting is the term used to describe the controlled aerobic degradation of organics into a soil-like substance called compost. ‘EcoHumus’ is a term taken from Peter Morgan (see references) and is a more appropriate word to use for the material removed from a Fossa Alterna because it is produced passively underground and has a slightly different composition.

Pit humus is the term used to describe the material removed from a double pit technology (for creditsS.4, click the pictureS.5 or S.6)]]because it is produced passively underground and has a slightly different composition than compost. Both products can be used as soil conditioners.'''
The process of thermophilic composting generates heat (50 to 80°C80 °C) which kills the majority of pathogens present. For the The composting process to occur there must be requires adequate carbon, nitrogen, moisture, and air. The [[Double Ventilated Improved Pit|Double VIP]] (S.4), [[Fossa Alterna|Fossa Alterna]] and (S.5) or [[Fill and Cover - ArborlooTwin Pits for Pour Flush|ArborlooTwin Pits for Pour Flush]] (S.6) are ambient -temperature variations of high-temperature composting. In these technologies, there is almost no increase in temperature rise because vegetable matter is lackingthe conditions in the pit (oxygen, moisture, C:N ratio) are not optimized for composting processes to take place. For that reasonBecause of this, the end material is not actually ‘compost’ and is , therefore , referred to as ‘EcoHumus’‘pit humus’. The texture and quality of the pit humus depends on the materials which have been added to the excreta (e.g., soil added to a Fossa Alterna) and the storage conditions.
The WHO guidelines state on excreta use in agriculture stipulate that the compost should achieve and maintain a temperature of 50°C 50 °C for at least one week before it is considered safe (although to achieve use. Achieving this value, however, requires a significantly longer period of composting is required). The WHO guidelines should be consulted for detailed information. For systems technologies that generate EcoHumus in-situ (i.e. Fossa Alterna)pit humus, a minimum of 1 year of storage is recommended to eliminate bacterial pathogens and reduce viruses and parasitic protozoa. WHO guidelines should be consulted for detailedinformation.
Compost/EcoHumus ===Design Considerations=== It has been shown that the productivity of poor soil can be used beneficially to improve the quality of soils improved by adding nutrients applying equal parts compost and organics and improving the soil’s ability topsoil to store air and waterit. The texture and quality of the EcoHumus depends on the materials, which have been added to the excreta (especially the type of soil)output fromone Fossa Alterna should be sufficient for two 1.5 m by 3.5 m beds.

==Adequacy=Appropriateness===Compost/EcoHumus and pit humus can be beneficially used to improve the quality of soil. They add nutrients and organics and improve the soil’s ability to store air and water. They can be mixed into the soil before crops are planted, used to start seedlings or indoor plants , or simply mixed into an existing compost pile for further treatment. Vegetable gardens filled with pit humus from the Fossa Alterna have shown dramatic improvements over gardens planted without soil conditioner. The use of pit humus has even made agriculture possible in areas which otherwise would not have supported crops.
For poor soils===Health Aspects/Acceptance=== A small risk of pathogen transmission exists, but, if in doubt, any material removed from the pit or vault can be further composted in a regular compost heap before being used or mixed with additional soil and put into a ‘tree pit’, i.e., a nutrient-filled pit used for planting a tree. Compost and pit humus should not be applied to crops less than one month before they are harvested. This waiting period is especially important for crops that are consumed raw. As opposed to sludge, equal parts which can originate from a variety of domestic, chemical and industrial sources, compost and top soil pit humus have shown to improve productivityvery few chemical inputs. The output only chemical sources that could contaminate compost or pit humus might originate from one Fossa Alterna should be sufficient for two 1contaminated organic material (e.g.5m , pesticides) or from chemicals that are excreted by 3humans (e.5m bedsg. Vegetable gardens filled with the Eco- Humus from the Fossa Alterna have shown dramatic improvements over gardens planted without compost, and has even made agriculture possible in areas which would have not otherwise supported cropspharmaceutical residues).
==Health Aspects/Acceptance==A small risk of pathogen transmission existsCompared to the chemicals that may find their way into wastewater sludge, but if in doubt, any material removed from the compost and pit humus can be composted further in a regular compost heap, or mixed with additional soil considered as less contaminated. Compost and put into a ‘tree pit’pit humus are inoffensive, iearth-like products.eRegardless, people might refrain from handling and using them. a nutrientConducting demonstration activities that promote hands-filled pit used for planting a treeon experience can effectively show their non-offensive nature and their beneficial use.

Then, it can be used without furthertreatment. Note; compost from excreta Workers should not be applied as fertilizer to vegetables eaten rawwear appropriate protective clothing.
As opposed to sludge, which originates from a variety domestic, chemical and industrial sources, compost has very few chemical inputs. The only chemical sources that could contaminate compost might originate from contaminated organic material (e.g. pesticides) or from chemicals that are excreted by humans (e.g. medication). Compared to the cleaning, pharmaceutical and processing chemicals that may find their way into sludge, compost can be considered as a less contaminated product.===Field experiences===
