Hydroponics and Soil Manipulation

Electronic “franken-soil” Boosts Crop Growth

By B.N. Frank

Genetically modified food has been controversial for many years.  Genetically engineered salmon has been referred to as “Franken-fish”. Earlier this year, the Food and Drug Administration approved gene-edited pork for human consumption as well.  Yikes!  More recently, scientists announced that electronic soil (aka “franken-soil”) can be used to increase crop growth.

Electronic ‘franken-soil’ enhances crop growth by 50%, experiments reveal

LINKÖPING, Sweden — Scientists have developed an innovative “electronic soil” that significantly boosts crop growth, with barley seedlings growing 50 percent more when their roots receive electrical stimulation through this “eSoil” layer. This breakthrough, spearheaded by researchers from Linköping University in Sweden, focuses on soilless cultivation, commonly known as hydroponics.

“The world population is increasing, and we also have climate change. So it’s clear that we won’t be able to cover the food demands of the planet with only the already existing agricultural methods,” says Professor Eleni Stavrinidou, leader of the Electronic Plants group at the university, in a media release. “But with hydroponics, we can grow food also in urban environments in very controlled settings.”

Her team has developed a specialized electrically conductive cultivation substrate, termed eSoil, designed for hydroponic cultivation. Their research demonstrates that barley seedlings grown in this conductive medium and electrically stimulated at the roots exhibited up to a 50-percent increase in growth over 15 days.

Hydroponic cultivation allows plants to grow without soil, relying only on water, nutrients, and a substrate for root attachment. This closed system facilitates water recycling and precise nutrient delivery, requiring minimal water and keeping all nutrients within the system, a feat not achievable in traditional farming.

The team highlights that hydroponics also supports vertical farming in large towers, optimizing space use. While currently used for crops like lettuce, herbs, and some vegetables, grains have not been commonly grown hydroponically, except as fodder.

In their study, the researchers successfully cultivated barley seedlings hydroponically, enhanced by electrical stimulation.

“In this way, we can get seedlings to grow faster with less resources. We don’t yet know how it actually works, which biological mechanisms that are involved,” Prof. Stavrinidou notes. “What we have found is that seedlings process nitrogen more effectively, but it’s not clear yet how the electrical stimulation impacts this process.”

Typically, hydroponics employs mineral wool as a substrate, a non-biodegradable material produced through energy-intensive processes. However, the team’s eSoil is a blend of cellulose and a conductive polymer called PEDOT, marking its first use in plant cultivation and creating a plant interface in this way.

Unlike previous research that used high voltage for root stimulation, this new “soil” has the advantage of low energy consumption and no high voltage risks.

“We can’t say that hydroponics will solve the problem of food security. But it can definitely help particularly in areas with little arable land and with harsh environmental conditions.” Prof. Stavrinidou concludes.

The research is published in the journal Proceedings of the National Academy of Sciences (PNAS).

DEA Targeting Hydroponic Garden Store Patrons

DEA Raided This Woman’s House After She Shopped At A Garden Store

Posted: Updated:
POLICE OFFICER GUN

Angela Kirking never thought shopping for garden supplies would lead to agents from the Drug Enforcement Administration waking her up with guns drawn, but that’s what happened last October.

“I bought a bottle of organic fertilizer, a 16-ounce bottle,” said Kirking, a 46-year-old face-paint artist. “Three weeks later I was raided by DEA.”

The DEA is refusing to answer questions about the law enforcement operation targeting an Illinois garden store that has netted Kirking and at least 10 other people. But Kirking and her lawyer contend it’s a case of misplaced priorities and federal overreach. They’re asking why the DEA is treating ordinary customers of a garden store selling hydroponic equipment as if they were major drug dealers.

The Oct. 11, 2013, raid on Kirking’s house, first reported by Patch, involved four DEA agents and five Shorewood, Ill., police officers, according to a police report. Its alleged yield from Kirking’s art room, whose entrance is guarded by beads: 9.3 grams of marijuana, or less than one-third of an ounce.

Now Kirking’s defense lawyer, former Will County (Ill.) prosecutor Jeff Tomczak, is trying to have the search warrant and the two misdemeanor charges it produced thrown out.

Kirking’s visit to the garden store, Midwest Hydroganics, was the predicate for the whole investigation of her, according to Tomczak. “100 percent nothing else,” he said, calling that far too thin a thread on which to base a search warrant.

In the search warrant application, a Braidwood, Ill., police officer assigned to the DEA, Donn Kaminski, wrote that he had observed Kirking exit the garden store “carrying a green plastic bag containing unknown items.” Kaminski stated he had “previously conducted numerous investigations that involved the surveillance of Midwest Hydroganics and persons purchasing items at Midwest Hydroganics, which has led to the arrest of suspects for production of cannabis sativa plants and production of cannabis.”

A man answering the phone at the Midwest Hydroganics store declined to comment on the DEA operation.

Kaminski wrote that he then sifted through Kirking’s household trash, detecting “a strong odor of green cannabis” in one plastic trash bag, and compared her home’s electrical bill to that of her neighbors, finding that it was higher. Another officer conducted a field test on a green plant stem, which allegedly tested positive for marijuana. That was enough for a judge to sign a warrant.

An application for a search warrant for a different Midwest Hydroganics customer, Tomczak noted, stated that police had found no evidence of marijuana plant residue in the trash — and suggested that was evidence a suspect was covering up his marijuana grow.

The result in Kirking’s case was an early morning raid on her home.

“They were in full attack mode, came at me guns raised, flashlights. Just like you see in the movies,” Kirking said. “I had to ask them for a warrant. I said, ‘Who are you,’ when they came in the bedroom. Somebody said, ‘DEA.'”

A spokesman for the Will County State’s Attorney described Kirking’s case as just one among many resulting from surveillance of the store.

“There are 11 total cases based upon search warrants that were written and charged based upon this type of surveillance in Will County by the DEA,” said Charles Pelkie, director of public affairs for the state’s attorney’s office. “Eleven of those cases are charged, eight have been prosecuted in Will County.”

Kirking’s alleged marijuana stash was paltry. But Pelkie said other searches have produced more serious amounts. The largest of these in Will County, he said, yielded 120 marijuana plants, 290,510 grams of cannabis and 178 Ecstasy pills. That raid has resulted in one person pleading guilty to a felony.

Pelkie said the Will County State’s Attorney makes its decisions on charges when the DEA presents its evidence. He refused to comment on whether targeting a garden store was the best use of the agency’s resources.

“With regard to how the DEA conducts its investigations, you really have to refer to them,” said Pelkie.

But on that count the federal agency is not being helpful. Special Agent Owen Putman, spokesman for the DEA’s Chicago Division, declined via email to comment on the operation targeting Midwest Hydroganics.

The Illinois law enforcement operation seems to follow the same pattern as a two-state operation out of Kansas City, Mo., that also involved the DEA. The effort dubbed “Operation Constant Gardener,” led by the Missouri State Highway Patrol, also staked out hydroponic garden stores and eventually arrested 14 people. To maximize publicity, those raids happened on April 20 of 2011 and 2012 — 4/20, also known as “Weed Day.”

After the initial favorable headlines, however, the other side of Operation Constant Gardener came into focus: Innocent gardeners had been harassed, and garden stores saw diminished business.

In the Kansas City suburb of Leawood, Kan., law enforcement agents clad in bulletproof vests and carrying assault rifles raided the home of a couple and their two children. The parents turned out to be former CIA employees. Even after no marijuana was found, police allegedly suggested to Adlynn and Robert Harte that perhaps their 13-year-old son used marijuana.

“These folks have never used drugs at all. They have the cleanest backgrounds ever,” said the couple’s lawyer, Cheryl Pilate. “They used a SWAT team — or a bunch of deputies dressed up like SWAT officers using SWAT tactics — which was totally inappropriate.”

Pilate said the couple’s ordeal started after the husband went to the hydroponic garden store to buy supplies for an educational indoor vegetable garden he planted with his son. The Hartes are now suing for damages.

In many cases, Pilate argues, the police rely on inaccurate and unreliable field tests like those used to identify alleged traces of marijuana in suspects’ trash. Her clients contend in their lawsuit that the supposed “marijuana” found in their trash was actually discarded tea leaves.

Pilate said police departments are quick to put out press releases when such raids turn up drugs or marijuana plants.

“What you hear about are the people who are charged. You generally don’t hear about the people who aren’t,” said Pilate.

In Illinois, the Will County State’s Attorney has so far not answered HuffPost’s request for statistics on how many search warrants were executed as part of the Midwest Hydroganics investigation that did not result in prosecutions.

Kirking, the face-paint artist who faces two misdemeanor charges for the small amount of marijuana found in her home, is hopeful the judge in her case will throw out the warrant. She thinks the garden store operation should stop.

“You feel very violated. I mean extremely violated. My husband and I were in shock for days afterwards — how did this happen?” she said. “It’s sad that they are resorting to this method.”

Vertical Farming

The Problem

By the year 2050, nearly 80% of the earth’s population will reside in urban centers. Applying the most conservative estimates to current demographic trends, the human population will increase by about 3 billion people during the interim. An estimated 109 hectares of new land (about 20% more land than is represented by the country of Brazil) will be needed to grow enough food to feed them, if traditional farming practices continue as they are practiced today. At present, throughout the world, over 80% of the land that is suitable for raising crops is in use (sources: FAO and NASA). Historically, some 15% of that has been laid waste by poor management practices. What can be done to avoid this impending disaster?

A Potential Solution: Farm Vertically

The concept of indoor farming is not new, since hothouse production of tomatoes, a wide variety of herbs, and other produce has been in vogue for some time. What is new is the urgent need to scale up this technology to accommodate another 3 billion people. An entirely new approach to indoor farming must be invented, employing cutting edge technologies. The Vertical Farm must be efficient (cheap to construct and safe to operate). Vertical farms, many stories high, will be situated in the heart of the world’s urban centers. If successfully implemented, they offer the promise of urban renewal, sustainable production of a safe and varied food supply (year-round crop production), and the eventual repair of ecosystems that have been sacrificed for horizontal farming.

It took humans 10,000 years to learn how to grow most of the crops we now take for granted. Along the way, we despoiled most of the land we worked, often turning verdant, natural ecozones into semi-arid deserts. Within that same time frame, we evolved into an urban species, in which 60% of the human population now lives vertically in cities. This means that, for the majority, we humans are protected against the elements, yet we subject our food-bearing plants to the rigors of the great outdoors and can do no more than hope for a good weather year. However, more often than not now, due to a rapidly changing climate regime, that is not what follows. Massive floods, protracted droughts, class 4-5 hurricanes, and severe monsoons take their toll each year, destroying millions of tons of valuable crops. Don’t our harvestable plants deserve the same level of comfort and protection that we now enjoy? The time is at hand for us to learn how to safely grow our food inside environmentally controlled multistory buildings within urban centers. If we do not, then in just another 50 years, the next 3 billion people will surely go hungry, and the world will become a much more unpleasant place in which to live.

 

     

 

Advantages of Vertical Farming

  • Year-round crop production; 1 indoor acre is equivalent to 4-6 outdoor acres or more, depending upon the crop (e.g., strawberries: 1 indoor acre = 30 outdoor acres)
  • No weather-related crop failures due to droughts, floods, pests
  • All VF food is grown organically: no herbicides, pesticides, or fertilizers
  • VF virtually eliminates agricultural runoff by recycling black water
  • VF returns farmland to nature, restoring ecosystem functions and services
  • VF greatly reduces the incidence of many infectious diseases that are acquired at the agricultural interface
  • VF converts black and gray water into potable water by collecting the water of
    evapotranspiration
  • VF adds energy back to the grid via methane generation from composting non-edible
    parts of plants and animals
  • VF dramatically reduces fossil fuel use (no tractors, plows, shipping.)
  • VF converts abandoned urban properties into food production centers
  • VF creates sustainable environments for urban centers
  • VF creates new employment opportunities
  • We cannot go to the moon, Mars, or beyond without first learning to farm indoors on
    earth
  • VF may prove to be useful for integrating into refugee camps
  • VF offers the promise of measurable economic improvement for tropical and subtropical
    LDCs. If this should prove to be the case, then VF may be a catalyst in helping to reduce or even reverse the population growth of LDCs as they adopt urban agriculture as a strategy for sustainable food production.
  • VF could reduce the incidence of armed conflict over natural resources, such as water
    and land for agriculture
