Rooftop Gardeners make Kimchi

Rough Google Translation:

The lecture room of Seoul National University, Professor Han Moo-young, graduate students, residents of Gwanak-gu, and foreign students from the School of Construction and Environmental Engineering gathered in this school. Those with pink rubber gloves on both hands sliced ??the radishes on one side and trimmed them on the other side. It was the day to make kimchi which will be delivered to neighbours.

“Just grab a bunch of spices and rub them on the cabbage.” Gwanak-gu residents Kim Hye-Ja (48) told me. This is how to spice the marinated Chinese cabbage. The master from Indonesia followed his this red sauce. Gita said, “I learned what kimchi is in my class. The Kimchi was made on the same day it was delivered to local residents in apartment complexes in Gwanak-gu by the local service organization, Yeong-Ok, CEO of Gwanak city agricultural network.

A graduate student Yoo Yoo (26) said, “These cabbages were grown using cutting-edge technology.” Seoul National University professors and students are raising their own crops and distributing them to local residents. On that day, 100 of the Chinese cabbages used in kimchi and all 100 of them were raised in a garden on the roof of the 35th Dong. Professor Han, Moo – Young, well-known the field of rainwater research, has made gardens on the rooftop where plants can be raised with only rainwater.

A water storage space of 5 cm above the roof was made, and 15 cm of soil was laid on the fabric. When it rains, water can be stored under the soil, so even if the drought is serious, food can be planted. In this garden, various crops such as sweet potatoes grow as well as cabbage.

Lee Jeong-hoon, professor of Seoul National University’s School of Mechanical and Aerospace Engineering, distributes tomatoes grown in research facilities to local residents. In April, Professor Lee built a green house of about 165 square meters in a gardens near Gwanak-gu. There are 60 tomatoes growing in the plastic house.

Thin nano-sensors, developed by Professor Lee, measure the amount of water and nutrients in the tomato stem. With this technology, we are studying how to control the amount of water and fertilizer and how to grow tomatoes while using less water. The professors and students delivered 70kg of tomatoes, harvested in August, to the elderly living alone, the next generation, and other difficult neighbourhoods in Gwanak-gu through the ward office. We will mature 30 kg of tomatoes harvested on the 11th, and donate them soon. Professor Lee said, “I also do research and share with people.”
