Complex microorganism “Sinyang 2” is winning popularity among farms across the country.
It can be easily introduced as it makes it possible to produce quality manure in a short period of time with less labour.
It was developed by Kim Chang Yu, section chief of Sariwon Kye Ung Sang University of Agriculture.
He majored in veterinary and animal husbandry, but he started his research into microorganisms in his 20s.
At that time, manure production was a labour-consuming work. The matter weighed on his conscience as a scientist.
He began to think about how to solve the issue: Microorganisms that disintegrate various organic matters such as rice straw and hay would be helpful.
With this idea, he buckled down to the research into microorganisms.
He toured mountains, rivers, lakes, swamps, seas and even untrodden places across the country in order to find out useful microorganisms.
Sometimes, he separated and examined thousands of microorganisms but failed to find out a single microorganism. And sometimes, he had to conduct a separation test again as the spore he had found out after making painstaking efforts died.
He presented his first research findings six years later, but they turned out unsatisfactory.
But he never gave up and directed more efforts to this end.
Twenty years later, he succeeded in developing complex microorganism “Sinyang 1” and thus made a great contribution to increasing grain production.
He was not satisfied with his success.
His next goal was to develop a complex microorganism conducive to promoting the growth of crops and increasing yields with less or no use of chemical fertilizers while increasing the fertility of soil.
He developed “Sinyang 2” which putrefies various organic matters and multiplies in large quantities in the soil to make biosynthesis of nutrients such as nitrogen.
Choe Song Ok, a farmer at the Sinhung Cooperative Farm, Kangnam County, Pyongyang, said: “Sinyang 2” is very effective. I produced over 10 tons of grains in the low-yielding fields where 2 to 3 tons were harvested in the past.
Kim Chang Yu was honoured with the title of Merited Scientist in 2019.
He is still devoting himself to the research into microorganisms.
