AN ORGANIC FERTILIZER AND THE MANUFACTURING PROCESS THEREOF

摘要

A process, according to the invention consists in that the municipal or zootechnical wastes sludge is dehydrated, composted and screened. A mineral wool is formed, so that its fibre length varies between 1 and 100 mm. The sludge and the mineral wool prepared in such way are mixed with brown coal at a following ratio - 50 % of dehydrated and composted sludge from municipal or zootechnical wastes and 20 % of brown coal. Mixed components are then composted for about a month. The fertilizer according to the invention permits mixing it with other selective acting fertilizers, which enhances its employment for very demanding crops (cultivations).
