2.1 Descrição curta da tecnologia

Definição da tecnologia:

Improving farmyard manure by protecting it from direct sunlight, rainfall, and runoff to reduce volatilisation and leaching

2.2 Descrição detalhada da tecnologia

Descrição:

Farmyard manure is the most common form of organic fertiliser applied to crops in the midhills of Nepal. Farmyard manure has a high proportion of organic material which nurtures soil organisms and is essential for maintaining an active soil life. Typically, only about half of the nutrient content of farmyard manure becomes available for crop growth during the first year after it is applied to the soil. The rest of the nutrients are channelled through soil biotic processes and are released in the following years. The high organic matter content and the more active soil life improve or maintain a friable soil structure, increase the cation exchange capacity, the water holding capacity, and the infiltration rate, and reducing the risk of soil pests.
Indigenous methods of preparing and using farmyard manure vary depending on the ecological zone, access to bedding material from crop or forest land and to crop residues and fodder, the availability of labour, and other factors. Traditionally, Nepali farmers take the manure out of their sheds to dry it for 2-3 days and then carry it to the field where it is left in small heaps for a number of days before being spread and incorporated into the soil.
Farmers rate the quality of manure according to which livestock species it comes from. These ratings have been confirmed by nutrient analysis as cattle manure (NPK%: 0.6, 0.13, 0.66) is considered to be better than buffalo manure (0.33, 0.25, 0.10), and horse manure; while pig (0.5, 0.18, 0.42), goat (0.6, 0.13, 0.99), and sheep manure (0.6, 0.13, 0.99) are considered better than cattle manure. Chicken manure (1.46, 0.51, 0.51) is considered the best of all.
It has however been shown that considerable nutrient losses occur if the manure is inappropriately handled or stored. Drying of the manure leads to loss of nutrients through volatilisation, and rainfall and runoff leads to leaching or washing out of nutrients. In addition, the common disposal of urine - the part of the excreta with the highest nutrient concentration - further reduces the level of nutrients in manure.
To reduce nutrient losses farmyard manure needs to be protected from direct sunlight; protected from rainfall or run-on; and protected from runoff. This can be achieved in a variety of ways using a variety of inputs. It is most important to protect the manure during storage and just before it is applied in the field to make the best use of this valuable local resource.

3.1 Principal/principais finalidade(s) da tecnologia

• Improve manure

3.2 Tipo(s) atualizado(s) de uso da terra onde a tecnologia foi aplicada

Terra de cultivo

• Cultura anual

Comentários:

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

3.8 Redução, prevenção ou recuperação da degradação do solo

Especifique o objetivo da tecnologia em relação a degradação da terra:

• Reduzir a degradação do solo

4.1 Desenho técnico da tecnologia

Especificações técnicas (relacionada ao desenho técnico):

a) Covering the farmyard manure with a roof made of tin sheet or plastic sheets. Cheaper alternatives are:
- a thatched roof
- shading with creepers like cucurbits
- planting broadleaf mustard on the heap
- applying a covering of crop residues or forest material

b) Farmyard manure is traditionally carried to the fi elds in doko baskets and left there in unprotected heaps to be incorporated often weeks and sometimes several months later (top and bottom left). It is much better to incorporate it on the day of transport as the longer it is left out on the fi elds in heaps the greater are the nutrient losses from the heaps (bottom right). Alternatively it can be stored in a corner of the fi eld covered with plastic sheets, crop residues, or in some other way (top right).

Technical knowledge required for field staff / advisors: low

Technical knowledge required for land users: low

Main technical functions: increase in organic matter, increase in soil fertility, increase in soil productivity

Secondary technical functions: increased infiltration rate and water holding capacity, improved soil physical properties (friability,easier soil preparation)

Layout change according to natural and human environment: protect farmyard manure; change application

Off-farm income specification: In most farm households, off-farm income plays at least a minor and increasingly a major role. Occasional opportunities for off-farm income present themselves in the form of daily labour wages. Some households’ members receive regular salaries, whilst an increasing number of Nepalis are working in India, the Middle East, Malaysia, and elsewhere and sending remittance incomes home.
