Presented to the 31st National Festival of Science and Technology recently held at the Sci-Tech Complex in Pyongyang were many valuable agro-technical findings and products.

They include a system for building and searching database on the country's soil analysis that helps control the land resources in a unified way.

There are also a method of evaluating crop estimate of grain based on information technology and a balanced vibrating combined soil machine which ensures plowing and harrowing at the same time.
