Researchers of the Academy of Agricultural Science have recently introduced various kinds of effective fertilizers.
They developed a nano silicon fertilizer that can improve the absorption of nitrogen, phosphor, potassium and magnesium even under low temperature and sunshine and further enhance the resistance against falling by rainy wind, as well as the tolerance to diseases.
South Phyongan, North and South Hwanghae, and North and South Hamgyong provinces built silicon fertilizer production bases in close cooperation with the academy and are now increasing production.
The fertilizer is winning high appraisal among users, as it is convenient in transport and storage and can increase crop yield up to 10 percent per hectare against the previous period.
Besides, the researchers laid a foundation for producing an effective potato nutritive liquid fertilizer at low cost by making use of locally-available raw materials.
