2. Descripción de la Tecnología MST

2.1 Breve descripción de la Tecnología

Definición de la Tecnología:

Collection of cattle urine in improved cattle sheds for use as liquid manure and organic pesticide

2.2 Descripción detallada de la Tecnología

Descripción:

Nitrogen is the most important macronutrient for plants, and high crop productivity can only be achieved by making sufficient nitrogen available to crops. Nitrogen is also the most limiting nutrient in farms across Nepal’s midhills. Traditionally farmers applied farmyard manure to fertilise their needs. In many places this is being supplemented or even entirely replaced by inorganic fertiliser - mainly urea. The price of inorganic fertiliser has increased continuously in recent years and it is only available in limited quantities in areas far from the roadheads. On the other hand, cultivation practices are intensifying with increased cropping intensities and more nutrient-demanding crops as, for example, local varieties are replaced by hybrids and new crops are grown. This can easily lead to declining soil fertility and nutrient mining if it is not compensated for by an equivalent increase in organic or mineral fertilisation.
Cattle urine is a viable alternative to mineral fertiliser. Of the nitrogen excreted by cattle, 60% is found in the urine and only 40% in dung. In traditional sheds, urine is left to be absorbed in the bedding material, while excess urine is channelled out of the shed and disposed of. The technology described here - improved cattle sheds- are designed for collecting the urine in a pit or drum. This pit is generally located in the shed itself or just outside connected to the drainage channel through a pipe and protected from rain and runoff. Where urine is collected for incorporation in farmyard manure, the pit may be directly connected to the manure pit or heap. Urine that is going to be used as liquid manure or organic pesticide has to be stored in a drum for fermentation.
A household with two cattle can save the equivalent of purchasing about 100 kg of urea over one year by applying urine either directly as liquid fertiliser or as a component in improved farmyard manure.

Comentarios:

Major land use problems (compiler’s opinion): Intensifying cultivation practices with either 1) inadequate application of fertilisers leading to a decline in soil fertility and the mining of soil nutrients or 2) application of too much fertiliser causing environmental problems through excessive leaching, and losses of fertiliser in surface runoff and consequent eutrophication or nitrification of streams, ponds, or groundwater.

4.3 Actividades de establecimiento

	Actividad	Momento (estación)
1.	Provide slight slope to the cattle shed floor
2.	Dig a draining ditch and a collection pit, if possible at the lowest point inside the shed. If this is not possible, an outside pit should be dug, protected from rain and runoff, and connected with the draining ditch through a pipe or a channel.
3.	Make the floor as impermeable as possible; e.g. with cement (expensive and durable), stone slabs, soil compaction, or clay (cheap but not durable). The more impermeable the floor, the more urine can be collected.
4.	Provide a jug/’decapitated’ plastic bottle/cup/etc. to scoop the urine out of the collection pit into the fermentation drum.

4.5 Actividades de establecimiento/ recurrentes

	Actividad	Momento/ frequencia
1.	When the collection pit is full, the collected urine has to be removed from the pit and stored in a plastic drum for fermentation.
2.	The urine is applied as liquid fertiliser by jug or through drip irrigation.

4.6 Costos e insumos necesarios para actividades de mantenimiento/ recurrentes (por año)

Comentarios:

It is clear that cattle or buffaloes are required for urine production. To help farmers to use their own resources, it is suggested to start with the cheapest and simplest form of urine collection and a compacted sloping floor and a collection pit within the shed. This allows the farmer to see the benefits of collecting the urine and will encourage them to invest in more expensive materials to improve the efficiency of urine collection. Cost as in January 2007

Comentarios:

The high cost of mineral fertiliser means that the establishment costs are soon recovered. In the long-term, the major reduction in fertiliser cost leads to increased benefits.

6.5 Adopción de la Tecnología

Comentarios:

Comments on spontaneous adoption: Approximately 30% of SSMP supported farmers groups and about 15% none members of SSMP supported groups adopted the tehnology.

6.7 Fuerzas/ ventajas/ oportunidades de la Tecnología

Fuerzas/ ventajas/ oportunidades desde la perspectiva del compilador o de otra persona de referencia clave
The use of urine collected on-farm reduced the requirement for mineral fertiliser which reduced production costs and outside dependency How can they be sustained / enhanced? Further promotion of the technology will increase this impact
Human urine can also be used to fertilise crops, but needs to be fermented longer and may be socially less accepted How can they be sustained / enhanced? Promote the use of urine further and show there is no problem with using human urine
Applying urine as a liquid manure also irrigates the crops (fertigation) How can they be sustained / enhanced? The link between urine application and drip irrigation, or other forms of smallscale irrigation, should be promoted. It has been tested and applied successfully by farmers related to SSMP in Syangja and Surkhet in western Nepal

6.8 Debilidades/ desventajas/ riesgos de la Tecnología y formas de sobreponerse a ellos

Debilidades/ desventajas/ riesgos desde la perspectiva del compilador o de otra persona de referencia clave	¿Cómo sobreponerse a ellas?
The initial costs incurred whilst improving a durable shed using cement may hinder adoption	Simpler methods such as using clay soil, compacting the fl oor, and using stone slates may, however lead to less urine being collected
Project incentives (cement, plastic drum) have hindered adoption in some places	No incentives should be provided, rather very simple methods should be demonstrated and adapted to local conditions
Urine collection is feasible for subsistence farm households or small scale commercial producers. It may, however, not be applicable for larger scale commercial vegetable producers as a balance between area needed for livestock and growing the crops is needed	Urine could become a tradeable commodity which would see large-scale livestock producers selling their urine to large-scale vegetable producers.
