2.1 技术简介

技术定义:

Smallstock manure production technology is an easy and efficient method to produce organic fertilizer for the conservation and improvement of soil fertility.

2.2 技术的详细说明

说明:

The main item within this practice is the so-called fosse fumière - a 1-2 m deep and 3-4 m diameter circular pit, enclosed by a stone wall. The pit has a double function: it is the place where manure is produced and it serves as shed for small ruminants (goats, sheep), particularly to avoid uncontrolled grazing /browsing during the cropping season (from April until November). Animals are fed in the fosse, and they drop their faeces, which together with chopped organic material accruing from the kitchen and field activities, piles up in the pit for decomposition. The fosse is partly roofed to provide optimal micro-climatic conditions: partial shading, partial exposure to sunlight and appropriate moistening through rainfall. Inside the pit, one or more circular terraces (0.5 m high, 0.5 m wide) serve as resting area for the animals. The terrace riser need to be plastered or reinforced with stones, particularly in case of loose soil, to avoid damage caused by animal trampling. After decomposition the manure is removed from the pit and distributed on the fields beginning of each cropping season (March). Then straw bedding is renewed and the process starts from scratch. During the dry season from December to March smallstock is left to graze freely on the fields and pastures.
