One of the known problems of farmers in the world is proper irrigation techniques. It is obvious that they have been puzzling over the years in order to provide the plants with the nutrients they need. This issue also poses an obstacle in space.

One of the known problems of farmers in the world is proper irrigation techniques. It is obvious that they have been puzzling over the years in order to provide the plants with the nutrients they need. This issue also poses an obstacle in space.

But the U.S. Space and Aviation Administration NASA It is so determined that once the Plant Irrigation Management (PWM) Project is complete, it will be one step closer to determining the most effective method of growing plants in space and adding the necessary water.

This project is part of research that examines how to feed astronauts on long-term trips to the Moon and Mars. Since they will spend weeks, months or even years in space, what they will eat during this period is a matter of research in itself.

Tyler Hatch, a scientist with the PWM Plant Irrigation Management Project, said: “NASA has shown in the past that growing plants in space is a reasonable way of providing food. From a horticultural standpoint, yes, it is possible.”

In previous projects, the researchers found that providing the necessary aeration and irrigation to the root of the plant in zero gravity was a challenge.

WITH A BARE EYE

Hatch and his team worked with plant biologists at NASA Kennedy Space Center to identify the problems that arose when growing plants on the International Space Station, and what the plants needed.

The researchers focused on how to deliver water throughout the plant’s life cycle and examined two main ways water can reach the plant’s root zone. The first is soil irrigation, which is a traditional method, and the other is hydroponic, ie aquatic plant cultivation; in the second, there is no soil and the plant is placed directly in the water.

The team developed artificially-simulated-plants to be used during this project process. Since using live plants would be quite challenging – especially because of the duration of their shelf life – they tried to reproduce the root system and evaporation rate of a living plant by using felt, foam and sponge to produce artificial plants.

In this way, there is no need to use real herbs.

While conducting the experiment, the plant conditions similar to those on Earth provided the necessary nutrients and sugar-containing juice. In addition, it can be said that the plant has an advantage that it can be seen with the naked eye while absorbing the colored fruit juice.

Data collection focused on the visual side of the experiment and how quickly the plants absorb the juice. The PWM process was recorded with cameras on the space station.

After the first space station operations completed at the end of February, the PWM Plant Irrigation Management project completed the last repetitions in April. The team has collected important data and is hoping for more tests in the future.

After the successful completion of these experiments, Hatch shared the following words:

“It was very satisfying to carry out this experiment in space, which will be effective in the food stocks of astranotes in the future. On the other hand, it was an extraordinary opportunity to fit the experiment in a year and collect the data again in this short time.
