Effective Microelement Fertilizer Developed
“We still have a lot of things to do.” This is what the researchers of the microelement research team of the Central Experiment and Analysis Institute of the State Academy of Sciences say when they receive congratulations for their achievement, an amino-acid microelement fertilizer which is effective in improving the viability of plants. The fertilizer has high fertilizing effects with a less amount of loss. It raises the quality of grains, enhances crops’ resistance to diseases and improves physiochemical and biological characters of soil. The main ingredient of the fertilizer is the Kumgang Medicinal Stone which is abundantly found in Korea.
The researchers of the institute began their research of the stone in the 1980s. Their dozens of years of research turned out several products including a health drink. Through deep-going studies the researchers found out that the stone has got over 50 kinds of elements, including macroelements like Si, Ca, Mg, P and K, and microelements such as Fe, Cu, Zn, Mn, B and Mo and rare-earth elements like La and Ce while having good solubility with a high biological effect. They buckled down to the work to make microelement fertilizer from the stone. A research team was organized headed by Kim Chol Ho. At last they made a fertilizer through painstaking studies and applied it to the field. But the result was not so good as they had expected. They knew it was largely because they tried to make it the way other countries did. (They made the fertilizer using salt as the source of microelements.)
Now the researchers made an inorganic microelement fertilizer from the Kumgang Medicinal Stone first. Applying it into practice for a few years they found out the limitation of it, and solved many scientific problems to improve the effectiveness of the fertilizer. The other researchers of the institute also helped their work. Cha Jong Chol handed them the reference data he had collected while doing his own task, and Ri Song Su and Yang Ki Ryong donated their research successes. Finally, an amino-acid fertilizer was developed thanks to the collective efforts. On the basis of the trial application of it into the 100 hectares of crop fields for verification of its effect, they introduced the fertilizer into several areas of different provinces.
