2.1 Short description of the Technology

Definition of the Technology:

Traditional compost making using locally available materials

2.2 Detailed description of the Technology

Description:

compost is made in a pit. A pit is dug of 3m diameter and 3m deep.Ashi is pread at the bottom followed by a 4" layer of smooth pasture grass thten all crop remaining, slashed grass, tree leaves, sisal leaves, farm yard manure, animal urine and ash are filled into the pit at laternate layers. 3 people can dig the pit in one day waste domestic water ( washings and cleanings) are daily poured into the mixture. It takes 3 1/2 months to fill up into a heap of 1/2 above the ground level smooth grass is then covered at the top while pouring urine and waste water continues. The final product is a greysh powder like material the compost is spot applied to planting hole at 1/4 litre per hole once after every three years she grows maize, sorghum, finger millet and millet. She intercrop with beans, pigeon peas, cowpeas and groundnuts. The compost is not applied to legumes. The compost increased yield from 3 bags/acre to 20-24 bag/acre of maize. The compost increase soil fertility and soil structure and texture. The emptied pits are usually filled again. Seeds can be mixed with the compost on sowing as it has no side effect. She sells to others the compost at 100/= Tshs ( 0.125 USD) per tin. Maintenance is pouring of waste soap water and cattle urine to catalyse decomposition.
