Necessary Breeding Conditions
- Feeding – A wheelbarrow of manure, wetted the previous day is used for feeding one bed every 15 days.
- Temperature – The optimum temperature for keeping worms is 20 – 25º C. The critical temperature is over 35º C. In winter the worms are protected against low temperatures by a thick layer of manure on and at the sides of the beds.
- Moisture– The optimum moisture is 65 - 70%. For that purpose the beds are wetted with about 3 l. water every 2 – 3 days.
- Light – It is harmful to the worms, so the beds should be covered with rush mats best of all.
- Partition of beds – After 3 - 4 months, the number of worms in a bed is twice higher because a new generation was bred. It requires partition of the bed. For the purpose a new empty bed is made and then it is populated with half of the worms from the old one. Eight beds could be obtained from one bed a year.
- Aeration – Every 45 days worms are overturned, at a depth of about 20 cm. using a pitchfork with blunt ends.
- Lifting of humus – The worms are fed in the middle of the bed only, and watering is scanty. After 3 days the biological manure containing the worms is lifted and transferred to the new bed. This procedure is carried out 3 times every 3 days. In this way all the worms are transferred into a new cell, and the humus is only left in the old bed. The humus is lifted on a cement site, dried for several days and screened through a sieve. Then it is packed in nylon bags.
Application of the biological manure:
· In floriculture /for pot and garden plants/; in vegetable production; in vine-growing and fruit-growing;
· It is effective for development of lawns in parks and playgrounds;
· It has a strong phytosanitary effect and controls the soil pathogens and diseases.
· A liquid manure for fertilization could be easily prepared from the solid manure.
Innovative activity of the biological manure
· Improved technology for production of biological manure for improvement of the nutrient content through combination of wastes and organic manure.
· Research activity: study different organic wastes and follow their influence on the nutrient content of the biological manure.
