The Antarctic crop of vegetables without soil and sunlight
When a person goes outside the Earth, even to a nearby Mars, he will have to take with him not food, but technologies for creating food in conditions that are fundamentally different from our planet. Because there is not enough canned food – you need to reproduce your daily food. Recently in the experimental greenhouse in the Antarctic have made progress in this direction.
The German station Neumayer III is located on the coast of the sixth continent, far enough from the pole. But here, too, it is useless to rely on the help of nature, so scientists took advantage of the chance and built a fully man-made high-tech greenhouse. It has an autonomous water supply system, isolated from the climate control station, artificial lighting and a system for monitoring the level of carbon dioxide.
Scientists use combined methods of growing edible plants, not focusing solely on hydroponics. And recently they received the first full-fledged harvest. It is 4 kg of salad, 18 fresh cucumbers and as many as 70 radishes – more than necessary for a festive dinner. Now, when the fundamental opportunity to grow plants without sunlight and soil is proved, the second task arises: how to increase the yield?
The potential of the Antarctic laboratory is limited, it is impossible to expand, to equip more beds, it remains only to improve the technology of plant growth. Researchers are sure that in a month they will go on streaming vegetable growing and will collect 5 kg of fresh products a week. With the prospect of continuing this at least year round, because if the work of the garden does not depend on the natural cycles on the planet, then it can give one crop after another constantly.
