Profitability of the agricultural sector
Mixed with fertilizer, they result in an excellent additive for trees. Then he started bubbling a ‘tea’ of fertilizer, using an aquarium pump in a plastic bucket. (“Even oil has its place in Permaculture,” he said. “The 20-liter bucket is the best application in the world for oil.”) He wrapped a heap of standard fertilizer in a fabric, like a bundle of a beggar, and dipped it in water.
Then he added molasses to feed the fermentation. After a few days, we would throw this brownish broth through the kitchen garden, to enrich the soil with beneficial bacteria. That was the idea, at least. A week after the workshop, I discussed these theories with Jeff Gillman, 41, an associate professor at the University of Minnesota and author of four books on
Gardening and environmental practices.
He declared himself to be a “believer in the general concept of Permaculture”. But he dismissed compost tea as “dementia”. Scattering a handful of strange microbes in a sea of soil, he said, is like launching 10,000 parachutists across the entire Sahara desert. They would not survive. The normal fertilizer, the solid thing in a backyard silo, “should already contain all the microorganisms that are beneficial to the soil,” he says.
And, if it doesn’t, “beneficial microorganisms move very, very quickly.” As Weiseman noted, Permaculture can be a “leap of faith.” But not jumping can have its own consequences. Starting with Mollison, permaculturists have predicted a near future of scarcity of resources. “Not just peak oil,” says Weiseman, “but also peak water and soil.” And the news, with its tone of economic decline and ecological catastrophes, feed the prophecies.
- In this impending dystopia, Permaculture would not be a lifestyle choice, but a necessity. “We know what is right,” says Weiseman. “We know what is best. We feel it in our bones and hearts. So we don’t do anything about it. Or we do. And
- I did. And it is bearing fruit. ”But the preparation for the final judgment in San Francisco, says Cody, is not that what drives a crowd of busy souls to dig horse manure on a Saturday morning, under the drizzle.
To Permaculture’s 12 central commandments, then, Cody added a thirteenth: “If it’s not fun, it’s not sustainable.” In other words, why lament the eventual collapse of our office buildings and industrial farms, when there is a banquet at to be done, right now, in our own backyards?

11 million lettuces grow at the premises of the company Spread – 30,000 per day – with the work of only 25 employees. Everything happens in an aseptic room, full of huge and long shelves. Automata move lettuce from one place to another throughout the day. As they grow, they are moved to places with the conditions of light, temperature and hydrometry adapted to this growing state.

Water enriched with nutrients.
Like Denmark, Japan has been a pioneer in the laborious development of “artificial light plant factories” for decades.Giants like Panasonic, Toshiba, TDK or Fujitsu have ventured into this field, with more or less success, transforming semiconductor production lines into “vertical fields” for which they created light, sensors and other adapted technologies.
- Without lossThe Spread, whose mother house was initially a fresh produce logistics company, is one of the few that managed to make the business profitable. “At first,
- we had difficulties selling lettuce, but it was relatively easy to create a brand image to attract customers, as we can
- produce quality for the same price. throughout the year “, explains Shinji Inada, head of the company.
The secret? “We have little loss,” he explains, and the products, easily found in Kyoto and Tokyo supermarkets, are preserved for some time. Adjusting this automated system took years. In another old Spread plant in Kyoto, which produces 21,000 lettuce plants a day, there are about 50 workers who move plants back and forth all the time. Admits that he thought of ecological relevance before starting this activity, but there were also other reasons.
“With the lack of labor, the low and the fall in production, I felt that a new production system was needed,” he explains. The average age of Japanese farmers is 67 years. “It is true that we use more energy compared to crops under the sun, but in return, we have a higher productivity on a similar surface,” he says.
