A new University of Houston study of hemp microbes can potentially assist scientists in creating special mixtures of microbes to make hemp plants produce more CBD or have better-quality fibers.

The study, led by Abdul Latif Khan, an assistant professor of biotechnology at the Cullen College of Engineering Technology Division, was published in the journal Scientific Reports from the Nature Publishing Group. The team also included Venkatesh Balan, UH associate professor of biotechnology at the Cullen College of Engineering Technology Division; Aruna Weerasooriya, professor of medicinal plants at Prairie View A&M University; and Ram Ray, professor of agronomy at Prairie View A&M University.

The study examined microbiomes living in and around the roots (rhizosphere) and on the leaves (phyllosphere) of four types of hemp plants. The team at UH compared how these microorganisms differ between hemp grown for fiber and hemp grown for CBD production.

“In hemp, the microbiome is important in terms of optimizing the production of CBD and enhancing the quality of fiber,” Khan said in a news release. “This work explains how different genotypes of hemp harbor microbial communities to live inside and contribute to such processes. We showed how different types of hemp plants have their own special groups of tiny living microbes that help the plants grow and stay healthy.”

The study indicates that hemp cultivation can be improved by better understanding these distinct microbial communities, which impact growth, nutrient absorption, stress resilience, synthesis and more. This could help decrease the need for chemical inputs and allow growers to use more sustainable agricultural practices.

“Understanding these microorganisms can also lead to more sustainable farming methods, using nature to boost plant growth instead of relying heavily on chemicals,” Ahmad, the paper’s first author and doctoral student of Khan’s, said the news release.

Other findings in the study included higher fungal diversity in leaves and stems, higher bacterial diversity in roots and soil, and differing microbiome diversity. According to UH, CBD-rich varieties are currently in high demand for pharmaceutical products, and fiber-rich varieties are used in industrial applications like textiles.

Houston urban agricultural nonprofit gears up for opening of new farm in Second Ward

GROWING FOR GOOD

Small Places, a Houston-based urban agricultural nonprofit, is looking forward to putting down roots beyond the fresh vegetables they grow in the East End.

After securing a 40-year land agreement with Harris County, the organization, which provides produce to families facing food insecurity in the Second Ward, is expecting to open their new farm in February 2025. Small Places’ founders hope the 1.5 acres of land named Finca Tres Robles, located at 5715 Canal Street, will be the beginning of Houston’s urban farming movement.

Founded in 2014 by brothers Daniel, Mark, and Thomas Garcia-Prats, Small Places was born out of the latter brother’s desire to work on an organic farm in his hometown of Houston. After farming in Maine, Iowa, and Nicaragua, Thomas had hoped to manage an urban farm but was unable to find a place. He then roped his brothers, who had no agricultural background at the time, into creating one.

“I joke that my journey in agriculture started the day we started out there. We didn’t grow up gardening or farming or anything of the sort,” says Daniel, Small Places’ director of operations. “It was a big learning curve, but how we approached it to our benefit was through our diverse set of backgrounds.”

Small Places began their need-based produce distribution programs through a partnership with nearby pre-school, Ninfa Lorenzo Early Childhood Center, providing food insecure families with fresh produce and later cooking lessons in 2017. When COVID-19 hit Houston in 2020, Daniel says Small Places pivoted towards becoming a redistribution center for their farming contacts who needed to offload produce as restaurants shut down, selling their crops through the organization. Their neighborhood produce program was then born, providing free boxes of produce to nearly 200 families in the East End at the pandemic’s peak.

“We found ourselves in the middle of two communities who were in need, one being people in our community who were losing jobs and were in need of food as well as our farming connections who were losing restaurant accounts,” Daniel explains.

Small Places currently assists 65 families living predominantly within two miles of their original location and they recently restarted their programming with Ninfa Lorenzo Early Childhood Center, and accepts Supplemental Nutrition Assistance Program benefits (SNAP) at their farm stand. Daniel says once Finca Tres Robles opens, Small Places plans to bring back cooking classes and educational seminars on healthy eating for which his brother Mark, a former teacher, created the original curriculum. The farm will also have a grocery store stocked with Finca Tres Robles' produce and eventually food staples from local vendors.

“Being social and preparing a meal can be fun, interesting, and delicious. Being able to pull all of that into a program was really important for us,” Daniel explains.

Farming successfully in the middle of Houston for their subsidized programs and produce market requires Small Places’ team to be strategic in their operations. Using his background in engineering and manufacturing, Daniel says they’ve closely monitored trends in which crops perform the best in Houston’s varied, humid climate over the past decade.

They also follow Thomas’s philosophy of allowing nature to work for them, planting crops at times when specific pests are minimal or integrating natural predators into their environment. And lots of composting. Daniel says they accept compostable materials from community members, before burying the raw organic matter in the earth in between their plant beds, allowing it to mature, then later using it to nourish their crops. Daniel says he and his co-founders hope to see more community-focused, sustainable operations like theirs spring up across Houston.

“Small Places is about hopefully more than one farm and really trying to turn urban agriculture and a farm like ours from a novel thing into something that’s just a part of communities and the fabric of Houston for generations to come,” Daniel says.

Houston area drone company on track to revolutionize the agriculture industry

in-flight innovation

Renowned American inventor Thomas Edison once said, "There's a way to do it better, find it."

That timeless adage has been the spark that has ignited countless technological advances over the years and Hylio is no different, applying it to its own mission to disrupt the agricultural technology space.

With rampant systemic inefficiencies with current crop spraying solutions negatively affecting farm economics, Hylio developed its AgroDrone, a precision crop spraying drone system that is revolutionizing ag-tech.

"Our company started about five years ago, when we were delivering in Central America and noticed the way people were doing spraying was extremely inefficient," says Arthur Erickson, CEO and co-founder of Hylio. "They were doing it either by hand or by plane or helicopter. If you are doing it by hand, you are doing it extremely slow and very inaccurate. If you're doing it by plane or helicopter, you're doing it faster, but you're extremely inaccurate."

In most cases, when farmers use traditional crop spraying methods such as helicopter or plane, up 90 percent of the fertilizer or pesticides miss their intended targets or float away.

However, AgroDrone, which was recently accepted into the Capital Factory accelerator, provides for a very precise method of applying those chemicals with its intuitive planning system, which monitors and controls the spray volumes using pre-existing map files or polygons.

"For the past year, we've been our own first customer," says Erickson. "We've used the technology in El Salvador, Honduras and Guatemala on 40,000 acres. We learned the product and what made it more efficient by using it in the field 10 hours a day. We built this from the ground up using it as a farmer would. We worked out all the bugs, optimized it and made it reliable, so when farmers are out there in the mud or in the rain, it still works."

The drone's flight software allows it to be completely turnkey. The electron-based application can be run on any cross platform and gives pilots control over the drone at all times.

Additionally, the redundant critical flight system ensures stable flight.

"Our software was made completely in house," says Erickson. "Like a Google map interface, you can set up your own pre-loaded missions, in different polygon shapes, draw them yourself or import polygon files and generate missions for the drone to fly."

Because of the radar altimeters fitted on the drones, farmers are able to reduce the amount of chemicals they use because the drones maintain optimal height over crops at all times, which minimizes drift and maximizes application quality.

"If you talk to any farmer that has 400 acres of corn, for example, and they want to get it sprayed, it would cost them maybe $400 times 10 for labor times 10 for chemicals, so about $8000," says Erickson. "The problem is they're providing a brute force solution to a problem that is very simple to solve with a drone.

"If they've got weeds on their 400 acres, and the weeds are only on one or two acres, little spots in the field, they just want to eliminate those spots, so they don't need to pay someone to spray their entire field, so they're saving the chemical cost per acre is $10 bucks. So if they run our drone for 10 minutes, they're literally saving $7,000 or more."

The innovators behind Hylio started the company because they were passionate about drones, but saw that the crop spraying system for farmers was broken and inefficient, so they sought to make the process better and more sustainable.

"Farmers are responsible for how we eat, how everyone eats," says Erickson. "The current technologies used in agriculture is outdated and not very cost effective. We looked at the farm economics and wanted to help develop viable solutions. Every farmer has to battle weeds; it is universal. All crop and weeds are different, but it is the same concept. The more you control the weeds, the more money you make at the end of the year. A farmer could lose 20 percent or more of their crops if they do not control their weeds properly. Despite the inefficiencies and razor thin margins, farmers still use helicopters and planes because they have to kill those weeds.

"There's a better way to do it with drones and it comes at a fraction of the price."

The AgroDrone starts at $19,300 and is delivered to the farmer fully tested and assembled. The package includes four pairs of 30,000 mAh 22V LiPo batteries, charging equipment, one handheld GPS tracker unit and access to the Hylio AgroSol Mission Control Software.

The software, which was designed by farmers for farmers, requires a recurring monthly fee that ranges from $100 to $500 depending on the level.

Hylio also provides the central device that can control multiple drones at the same time and service hundreds of acres per day.

"The people that are doing the weed control spraying for farmers literally won't come out because it's not worth their time to just come out and spray one or two acres," says Erickson. "So even if a farmer has a problem that they know is only on one or two acres, they have to spray the whole thing, because they market will only allow people to spray the entire amount. They cannot come out and afford to spray one or two acres. However, if you buy a drone, you can do it yourself with the click of a button. Farmers are saving literally $10,000 per application depending on how big their crop is."

According to the US Department of Agriculture, American farmers received $11.5 billion in subsidies in 2017. That number will be drastically higher in 2019 to offset the market losses farmers will see due to President Donald Trump's trade war with China.

With profits in continual decline, Hylio's mission to improve margins for farmers continues.

"Farming is heavily subsidized now," says Erickson. "None of them are making money, so they desperately need something to increase their bottom lines. We are here to make farmers' lives better and help them feed us better. It's a win win."

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”
