Earthworm compost and nutritive solution developed by a research group of Kim Il Sung University is drawing particular interest in the agricultural sector.
The compost is a biological humus produced by earthworms after consuming a large amount of organic waste.
“The earthworm compost promotes the growth of plants 1.5-2 times faster than ordinary compost and 1.3-1.4 times faster than chemical fertilizer,” said Kim Chol Song, head of the research group.
Kim and the research group have carried out extensive research on earthworm for decades.
In the past they extracted and separated glycolipoprotein G-90 pertaining to earthworm and developed an effective medicine for vascular system diseases and a plant physiology activator that improves the growth rate of plants.
The research results showed that earthworm digests any organic materials except metal, glass and rubber and decomposes them into substances that do no harm to people before excretion.
In particular, when the earthworm compost is applied to edible plants, it helps raise their harvest and improve the taste and nutritive value incomparably higher than when applying chemical fertilizers. So it is widely encouraged throughout the world.
The research group chose a strain of breeding earthworm with high productivity of compost by intensifying research on thousands of native earthworm species and widely bred it to establish a production method of quality earthworm compost and nutritive solution.
Last year, the earthworm nutritive solution was sprayed for trial to the vegetable fields of the Sosamjong Vegetable Cooperative Farm in Ryokpho District, Pyongyang, which was hit by flood and typhoon last year. The result was surprising: the farm harvested two times more vegetables than the previous year in the field whose yield was expected to be poor.
“The earthworm compost will produce an important effect if it is applied to all farmland across the country. We are now working on the improvement of the method of producing earthworm compost,” said Kim Chol Song.
