Last week New York City was host to the Indoor AgTech Innovation Summit, an event which drew 600 attendees, featured 90 speakers and included representatives from 42 countries. For a sector with some history of hyperbole about its role in feeding the world, the presentations and discussions during this event featured an overall balance of optimism and pragmatism. Many different kinds of “indoor” facilities were being considered at this meeting ranging from basic greenhouses all the way to multi-level “vertical farms” of the type pictured above. Industry players prefer to call their sector “controlled environment agriculture” or CEA. That is in contrast to mainstream agriculture which has the advantage of free solar energy and rainfall, but which must also deal with all the variables associated with weather and the limitations determined by geography.

The origins of CEA stretch at least as far the 17th and 18th century when “orangeries” in France were used in the winter to protect citrus trees grown in pots. For the last eight decades the Dutch have been technology leaders in the increasingly sophisticated and international greenhouse industry. In recent years CEA has been expanding world wide and trending towards a higher degree of control of the growing conditions including light, temperature, humidity, water, and carbon dioxide concentration. Fertilization in these systems is increasingly micromanaged in a soil-free setting such as “hydroponics” or “aeroponics.” Many tasks and process controls are automated.

This is an expanding industry with 7–8% annual growth projected for greenhouses and 15% per year for vertical farming. Greenhouses are commonly used to produce leafy greens, tomatoes, peppers, and cucumbers. The highest tech, vertical farming systems are currently focused on leafy greens and herbs. Even so, the packaged salad and leafy greens market is said to be in the range of $8.7 billion and projected to grow to between $13 billion and $25 billion within the next 5 years and CEA is likely to account for an increasing share.

Early detection and identification of pathogenic bacteria in food and water samples are essential to public health. Bacterial infections cause millions of deaths worldwide and bring a heavy economic burden, costing more than 4 billion dollars annually in the United States alone. Among pathogenic bacteria, Escherichia coli (E. coli) and other coliform bacteria are among the most common ones, and they indicate fecal contamination in food and water samples. The most conventional and frequently used method for detecting these bacteria involves culturing of the samples, which usually takes 24 hours for the final read-out and needs expert visual examination. Although some methods based on, for example, the amplification of nucleic acids, can reduce the detection time to a few hours, they cannot differentiate live and dead bacteria and present low sensitivity at low concentrations of bacteria. That is why the U.S. Environmental Protection Agency (EPA) approves no nucleic acid-based bacteria sensing method for screening water samples.

In an article recently published in ACS Photonics, a journal of the American Chemical Society (ACS), a team of scientists, led by Professor Aydogan Ozcan from the Electrical and Computer Engineering Department at the University of California, Los Angeles (UCLA), and co-workers have developed an AI-powered smart bacterial colony detection system using a thin-film transistor (TFT) array, which is a widely used technology in mobile phones and other displays.

The ultra-large imaging area of the TFT array (27 mm × 26 mm) manufactured by researchers at Japan Display Inc. enabled the system to rapidly capture the growth patterns of bacterial colonies without the need for scanning, which significantly simplified both the hardware and software design. This system achieved ~12-hour time savings compared to gold-standard culture-based methods approved by EPA. By analyzing the microscopic images captured by the TFT array as a function of time, the AI-based system could rapidly and automatically detect colony growth with a deep neural network. Following the detection of each colony, a second neural network is used to classify the bacteria species.

Powering plant growth with solar panels instead of photosynthesis could be a more efficient way of using the Sun’s energy for food. But it’s not all good news.

If you are an agricultural land owner and are considering your options to go solar, here are some resources to help you decide what’s best for you.

What if you could power the smart thermostats, speakers and lights in your home with a kitchen countertop? Stones, such as marble and granite, are natural, eco-friendly materials that many people building or renovating houses already use. Now, in a step toward integrating energy storage with these materials, researchers have fabricated microsupercapacitors onto the surface of stone tiles. The devices, reported in ACS Nano, are durable and easily scaled up for customizable 3D power supplies.

It would be convenient if the surfaces in rooms could charge smart home devices or other small electronics without being connected to the electrical grid. And although stone is a widely used material for floors, countertops and decorative backsplashes, it hasn’t been integrated with energy storage devices, such as batteries and capacitors. But stones, even those that are polished and seem smooth, have microscopic bumps and divots, making it difficult to adhere electrical components to them. Researchers have recently figured out how to place microsupercapacitors, which have fast charging and discharging rates and excellent power supply storage, onto irregular surfaces with lasers. So, Bongchul Kang and colleagues wanted to adapt this approach to build microsupercapacitors on marble. For further information see the IDTechEx report on Supercapacitor Materials and Formats 2020–2040.

The AI-powered robot is named “Polly” and will pollinate truss tomato plants in Costa’s tomato glasshouse facilities in Guyra, New South Wales.

In its commercial application, Costa wrote on its website that these robotic pollinators will drive between the rows, detect flowers that are ripe for pollination utilizing artificial intelligence, and then emit air pulses to vibrate the flowers in a certain way that mimics buzz pollination that is carried out by bumblebees.

Compared to using insects, like bees, and the human laborers that are occasionally required to aid with the growth of particular crops, pollination robots could provide future farmers with a major advantage, which is to improve productivity.
