It was in June Juche 101 (2012) when Ri Un Hui was appointed the workteam leader of crop-raising workteam No. 1 of the Sunan Cooperative Farm in Sunan District, Pyongyang.
As the fields in her workteam’s charge were of clay sand with the shallow soil depth, its yield was not so good.
When that year’s harvest proved poor, farmers consoled her by saying that it was pretty good for them.
However, she went to harvested fields to learn about their soil conditions and growing conditions of paddy rice in detail.
In the course of this, she was convinced that they could increase the yield by preventing damages by cold and damp in the latter growing period of crops.
From the next year, she directed efforts to producing active compost and blue-green algae bioactive manure with great effectiveness by means of a new compound fungus.
As a result, the yield of the fields, whose capacity used to be 5 to 6 tons per hectare, began to increase.
Without resting on her laurels, she encouraged stockbreeding, produced lots of organic manure with excrement of pigs and chickens with her workteam members and conducted subsoiling every year in a planned way.
Members of her workteam also produced homemade organic manure by breeding domestic animals including pigs and chickens.
By relying on scientific farming method, she explained and disseminated advanced farming methods to farmers in a positive manner and conducted farm works carefully in keeping with the growing periods of the crops in a scientific and technological way.
In Juche 109 (2020), in particular, when the fields were stricken by flood, she minimized crop loss by pushing ahead with application of various nutritive solutions and germicides together with her workteam members to improve nutritive conditions of paddy rice and protect them from damage by blight and harmful insects.
Thus, the workteam was honoured with the title of high-yield one and produced over 10 tons of grain per hectare.
“The fields are like part of my body. We can reap bumper harvest in every field when we take care of them as we would do our children,” Ri Un Hui says.
