WEST LAFAYETTE, Ind. (Inside INdiana Business) — A group of students from Purdue University has developed an organic additive that is designed to promote crops in vertical farms. The primary ingredient of the liquid biostimulant is soybeans. The innovation earned the team top honors during the 27th annual Student Soybean Innovation Competition sponsored by the Indiana Soybean Alliance.
To win this competition, Purdue University students must develop novel applications for soybeans that satisfy a market need.
“The goal of this contest is to highlight the versatility of soybeans while addressing a need in agriculture or the general public,” said Anngie Steinbarger, a farmer from Edinburgh and one of the judges for the contest. “This biostimulant is mostly made of a soybean protein, and it has been developed to help grow crops. This seems like a slam dunk for what we want from this competition.”
The soybean alliance says biostimulants help crops germinate rapidly, achieve greater plant mass and yield, and improve nutrient uptake. The team says its organic product is not a fertilizer, but it does improve grow rate and ease crop stress.
“One of the major successes we saw with our product is how great it worked with lettuce we’ve grown in the greenhouse,” said Purdue Sophomore Cai Chen, who is a member of the winning team.
Chen says when biostimulant was added to lettuce, it was 30% larger than standard lettuce.
In addition to Chen, the other members of the team include Nate Nauman, a sophomore from West Lafayette, and graduate student Emmanuel Alagbe of Nigeria. They will share the competition’s $20,000 top prize.
The team says soy protein peptides have antimicrobial and antibacterial properties which could help reduce the risk of foodborne illnesses in leafy greens.
Second place was awarded to a team that developed a hypoallergenic tape for athletes. Third place honors went to the creators of a biodegradable cosmetic face mask.
“Indiana soybean checkoff funds are used to find new uses and new markets for our soybeans; thereby creating demand and helping our farms to be more profitable and sustainable,” said Steinbarger. “Some of the products that evolve out of this contest could potentially have a positive impact on our soybean prices.”

Is The Future of Wheat Farming Inside And Up?
Researchers see big potential in indoor vertical wheat farms. Scientists say wheat yields could be exponentially larger in indoor, vertical venues

Researchers see big potential in indoor vertical wheat farms.
Scientists say wheat yields could be exponentially larger in indoor, vertical venues.
Future wheat farmers might ditch their rolling fields for indoor facilities filled with bright lights, multi-storied structures, and automated airflow. In recent years, indoor vertical farms have been commonly used to grow vegetables such as lettuce, kale, and microgreens. But little research has looked at how they might be used to grow staple crops until now.
A new study by scientists at the University of Florida compares the yields of growing wheat in a field with those of the crop grown in an indoor vertical farming. This method consists of growing food on sky-high stacked layers in shipping containers, tunnels, and warehouses using LED bulbs and hydroponic systems. The study, which was published in Proceedings of the National Academy of Sciences, shows that farmers can grow exponentially more wheat using indoor vertical farming than through the same amount of ground space in a field.
Using a crop simulation tool, researchers found that a 10-floor vertical farm, covering one hectare of ground space and operating under optimal conditions, was able to generate about 600 more times the yield than the average amount produced on one hectare of farmland. When they plugged in conditions for a 100-floor farm, the yield produced was 6,000 times more.

Scientists say that this method could be particularly useful for feeding the world’s growing population, which is expected to reach 10 billion by 2050. According to the FAO, wheat is the most widely grown crop in the world, representing 20 percent of people’s daily protein and food calories. And in recent years, experts say global production has not satisfied demand, triggering price instability and unrest.
Senthold Asseng, the lead author of the study and a professor of crop systems modeling, says indoor vertical farming will also deter farmers from clearing forests for agriculture. He adds that hydroponic methods use 90 percent less water and that housing crops indoors also eliminates the need for using herbicides or pesticides linked to environmental issues and human health risks.
“There is opportunity to grow huge crops and at the same time address the issue of environmental degradation,” Asseng says. “We need to nurture our environment because it’s the only environment we have.”
Despite the potential of growing wheat indoors, Asseng says there are barriers that will likely prevent many wheat farmers from choosing to use the method. These include the energy costs associated with powering an indoor facility.
But Asseng says the environmental benefit of indoor vertical farming could attract governments that are already subsidizing conventional agriculture to put some funding towards growing staple foods indoors.
“Many countries spend a lot of money on agriculture subsidies to keep agriculture production going. It might not always be the right way to consider the economics if it comes down to survival and stability,” he says. “Here is a new way of doing agriculture that will be really good for the environment.”

Vertical Farms Could Grow All The Wheat We Need
The global population eats a lot of wheat. It’s the most widely grown crop in the world, and it accounts for approximately 20% of the calories and proteins in the average human diet

For years, vertical farming has captured headlines, including on this very website. A new study published in the Proceedings of the National Academy of Sciences on Monday shows the practice could revolutionize the world’s ability to grow wheat.
The global population eats a lot of wheat. It’s the most widely grown crop in the world, and it accounts for approximately 20% of the calories and proteins in the average human diet. As the global population grows, we’ll need more of it to sustain humanity. With arable land a premium, the new study looks at if vertical farming—a method of growing crops in vertically stacked layers—could help.
To find out, the authors created two growth simulation models of a 10-layer vertical farm set up with optimal artificial light, temperatures, and carbon dioxide levels. They found that the simulation could yield up to a whopping 1,940 metric tons of wheat per hectare of ground per year. For context, the current average wheat yield is just 3.2 metric tons per hectare of land.
It makes sense that the authors would be looking into this now. Globally, one in nine people already face hunger, and the problem could become more acute as the population increases. The world could have to produce more than 60% more wheat to account for population growth. That won’t be easy; rising temperatures and other changes in growing seasons driven by the climate crisis are lowering crop yields around the world.
The new study offers an insight into how to address some of these problems. But right now, scientists are only offering simulations. Actually bringing these massive wheat crop yields to fruition would come with massive challenges.
For one, vertical farming is wildly expensive. It requires massive amounts of energy to work, especially because unlike traditional farming, it requires artificial lighting systems. The authors say their simulated systems would provide a light intensity for the crops 30 to 50% greater than directly overhead sunlight. Watering systems and technology to ensure optimal temperature and air quality conditions in these indoor environments would also be costly—not to mention energy-intensive. Depending on how the systems are powered, that could be a problem for the climate. Previous research shows that powering these systems could require vastly more energy than our current high-emissions food system.
“No one has ever attempted to grow food crops under artificial lighting that’s as strong as sunlight, much less strong, for the simple reason that it would require too much energy,” Stan Cox, a scientist and plant breeder at the Land Institute in Salina, Kansas, said in an email.
The new study’s authors note that recent innovations in solar energy are lowering the costs of electricity and lighting is becoming more efficient, but note crops grown this way are still not likely to be economically competitive with current market prices of agriculture. Cox found that to be an understatement.
“A decade ago, given the amount of light wheat plants require to produce one pound of grain, I calculated that growing the entire U.S. wheat crop indoors would consume eight times the country’s entire annual electricity output,” he said. “That was before recent advances in lighting efficiency. So, hey, maybe it would now use up only four to five times our total electricity supply! For one crop!”
Innovations in automation, the authors note, could further lower the costs of vertical farming. That may be true, but in our current economic system, that could be a problem for farmworkers, who are already seeing their pay get cut. For these reasons and more, vertical farming has been a controversial topic in agricultural and environmental circles.
The new study’s authors note that there are also many unanswered questions about growing wheat in indoor facilities. It’s not clear, for instance, what the nutritional value and quality of indoor-farmed wheat would be, or what diseases could arise in such facilities.
Though their projected crop yields are exciting, even if vertical farming does work, it can’t be the only solution to our agricultural issues. Other systemic changes, including reducing food waste, moving away from meat-centric agricultural systems, diversifying crops, and improving soil health, should also play a role.
“Under specific circumstances, and if the energy cost and profitability issues can be resolved, indoor vertical wheat farming might be attractive,” the authors conclude. “Nonetheless, the outcomes described here may contribute only a relatively small fraction (yet to be determined) of the global grain production needed to achieve global food security in the near future.”

VIDEO: Vertical Farming: The Only Way Is Up
Just like we've grown accustomed to living in compartments stacked directly on top and beside each other so too are lettuce and herbs

Just like we've grown accustomed to living in compartments stacked directly on top and beside each other so too are lettuce and herbs.
Agriculture is going vertical. Why? Because it saves water, increases efficiency, and provides us with fresh, local produce.
Vertical farming is the practice of producing food on upright surfaces. Instead of farming in a field, vertical farming grows plants stacked in layers, in structures like shipping containers or warehouses.
If this seems like an insignificant shift, unlikely to produce much effect, consider this: by 2050 the world's population is expected to grow by another 2 billion people.
Feeding everyone will be challenging. Vertical farming could be a solution.
What is vertical farming?
Assembled layer by layer under candy-colored lights, vertical farming has become an increasingly popular way for food producers to reduce costs related to space and energy consumption while increasing growth rates and nutrient values.
Of the many companies that are testing out this innovative farming method, Urban Crops uses a conveyor-like system to hold baby plants under LED ultraviolet lights. Their system is automated and relies on technology to program lighting and growing conditions specific to each species. And because they don't heat up, the bulbs can be placed closer to the leaves to encourage optimal light absorption.
In addition to not having to maintain an entire plot of land, Urban Crops boasts that vertical farming yields more crops per square meter than traditional farming or greenhouses. It also grows plants faster and can be used year-round. In theory, vertical farming can be practiced anywhere, which means that water-restricted locations can still harvest produce. Vertical farming uses up to 95% less water than traditional methods.
As Urban Crops' Chief Executive Maartin Vandecruys points out:
“Basically… every day is a summer's day without a cloud in the sky."
CES 2020: LG are launching exciting new indoor gardening technology.
While vertical farming could be the future of large-scale agriculture, companies like Urban Crops are also hoping that non-farming folk like yourself will be interested in investing in DIY versions. Because, while it makes sense to grow salad greens and edible flowers, trying to grow other foods like wheat for bread isn't yet an option: “At 10 cents a kilowatt-hour, the amount of energy it would take to produce wheat would [translate to] something like $11 for a loaf of bread," states, Vandecruys. Nonetheless, vertical farming could mean big changes in the way you think about “local" produce.
Vertical farming helps reduce the amount of questions for the consumer including its provenance, growing conditions and harvest date.
Data is useless unless you put it to work
Around the world, data-driven technologies are being used to keep indoor farming afloat. Detailed, real-time data collected via artificial intelligence, location services and IoT technology is used to analyze and produce better feeding models and optimal configurations, i.e. the concentration and scheduling of light and ratio of nutrients. Most recent is IoT company n.thing's Planty Cube, launched at this year's CES 2020.
Leo Kim, n.thing's CEO, came up with the idea for Planty Cube after creating an IoT-enabled smart pot called “Planty Square."
Planty Cube is a smart hydroponic vertical farm that relies on data from farming logs, which are fed back into a database called the “Cube Cloud" and analyzed with AI to help farmers determine optimal growing conditions. As the user adds more Planty Cubes to the vertical farm, this real-time, cloud-based system makes it easier for the grower to manage the overall farm, even remotely.
But even prior to sowing seeds, technology can help vertical farmers and consumers alike.
Automation, tracking and AI technology also opens up the potential to locate farms in urban, industrial, and even domestic spaces that can produce crops all year round.
This has the possibility to truly change the way cities source food. Most urban supermarkets are supplied from distributors around the world. Local indoor farms could decrease reliance on imports and reduce carbon emissions from transportation.
In the future, I hope to see supermarkets filled with vertical farms of their own.
The ups and downs of growing up
The vertical farming industry is booming. However, there are realities to consider before growing on a professional scale:
What are you growing and for whom?
Before you invest, do some market research. Get a sense of who your customers will be and your price point. Basically, if you can't sell it, you shouldn't grow it.
What is your distribution plan?
How will you physically get your produce to your customers? Find out who your end customers are and keep your farm as close to them as possible. Being local is an integral component to your success but this may present further challenges such as high cost of land, poor soil quality, and resource restrictions.
Will your building meet your needs?
Remember, indoor farming requires substantial amounts of power: lighting, pumps, HVAC, automation equipment, fans, computers etc. Not all buildings are equipped with the type of electricity you require. And if you're serious about getting into the vertical farming industry, you need to plan for future expansions.
Fortunately, vertical farming is being supported by more than just salad-starved individuals like me; location services and tracking technology are helping farmers retain high yields and prepare for the future.
