2.1 技术简介

技术定义:

Collection and proper storage of farmyard manure in heaps or pits

2.2 技术的详细说明

说明:

Farmyard manure - a varying mixture of animal manure, urine, bedding material, fodder residues, and other components - is the most common form of organic manure applied in the midhills of Nepal. Farmyard manure has a high proportion of organic material which nurtures soil organisms and is essential in maintaining an active soil life. Only about half of the nutrient content of farmyard manure becomes available for crop growth during the first year after it has been applied to the soil - the rest is channeled through soil biotic processes and the nutrients are released in the following years. The high organic matter content and the active soil life improve or maintain friable soil structures, increase the cation exchange capacity, water holding capacity, and infiltration rate, and reducing the risk of soil pests building up.
Indigenous methods of preparing and using farmyard manure vary widely depending on the ecological zone, access to bedding material from crop or forest land, access to crop residues and fodder, labour availability, and other factors. A prerequisite for the manure having a positive impact on soil fertility is that it is properly decomposed. The application of partially decomposed manure can increase the number of white grubs, red ants and other soil pests.
Decomposition is enhanced and the time it takes to happen is reduced if the manure is kept warm and moist (but not wet) at all times. Heaping the manure up or storing it in a pit helps. Whether it is best to heap up the manure or put it in a pit depends on the local climate. Heaping has the advantage of being less costly, while the pit method reduces runoff and the loss of nutrient rich fluids. Adding nitrogen in the form of urine (N) improves the carbon to nitrogen ratio.

• 一年一作

注释:

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.

4.1 该技术的技术图纸

技术规范（与技术图纸相关）:

a) Heap method
b) Pit method
c) Semi-pit method
The method should be chosen that
is most convenient and provides the
most favourable environment for
decomposition of the manure.
Generally heaps and pits are about 1 to 2m in diameter
depending on the amount of
manure produced and required.

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

Layout change according to natural and human environment: heaping or storage in pits

5.6 应用该技术的土地使用者的特征

说明土地使用者的其他有关特征:

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.

Market orientation of production system: Also commercial/ market

注释:

The high costs of mineral fertiliser mean that the establishment costs are recovered quarterly. Over the long-term, the major reduction in costs leads to large benefits.

6.5 技术采用

注释:

Comments on acceptance with external material support: Heap and pit methods have been very well accepted and adopted widely ( 60-70% ) of among participants in SSMP.The semi-pit method is not as accepted as the other methods due to its high initial establishment costs.
