Urban Farming

In a world where resources are diminishing and demands are rising, the value of land has significantly increased for clean energy and food production. Agrivoltaic farming represents a potential game-changing solution that can bring substantial benefits to both the energy and food sectors. The patented technology is a tubular solar photovoltaic (PV) module designed for agrivoltaic farming. The unique tubular nature of the system allows sunlight, water, and wind to reach the plants below while simultaneously harnessing solar power. Moreover, the tubular modules can provide consistent partial shading to protect the plants and reduce ambient temperature and ground moisture loss. This technology enables the dual use of land by integrating agricultural activities such as farming and gardening with solar power generation, maximising the value derived from the limited land. The combination of energy harvesting and agriculture has significant potential to improve farming productivity, increase land-use efficiency, reduce carbon emissions, and promote environmental sustainability. The technology owner is keen to collaborate with partners interested in agrivoltaic farming like farmers, gardeners, agritech companies, research centres, and ministries to test-bed and adopt their tubular solar PV technology. The technology owner is also seeking industrial partners (e.g., manufacturers, system integrators, architects, designers, etc) to co-develop a complete solar energy solution or integrate the tubular solar PV modules into specific use cases.

Indoor farming presents a range of different challenges to crop yields compared to outdoor farming activities. Traditional outdoor farmers intuitively know what environmental factors affect the growth of the crop. Indoor farming, on the other hand, requires the farmer to simulate the optimal climate conditions for expected crop yields. The indoor climate can either contribute to the yields or, in unfortunate circumstances, lead to the loss of the crop. However, it is not always easy to create an ideal environment for the crop.  This technology offer is a control system that allows the facility manager to align optimal crop conditions with the equipment settings in their facility, minimising the drift between settings and site-level crop conditions. The control system can also be used to compute the correlation between data across crop production, environment, and business performance. The control system can be customised further by adding other sensors for better accuracy of control.  The technology owner is keen to do R&D collaboration and licensing with innovative industrial automation companies specialising in product development of sensor networks and high-data throughput IoT gateways.   

Different plant species have different nutrient requirements. The current practice of urban farming uses a generic hydroponic nutrient solution that is suitable to most plant types, and a crude sensing system that only measures total ion content in the solution. This approach often results in nutrients deficiency and/or overloading and hence requires consistently monitoring. Overloading of nutrients not only increases the input costs, it also results in greater quantities of contamination in effluent to be disposed after harvest.  A targeted hydroponic nutrient solution reduces the need to periodically adjust the nutrient. The technology provider has studied and formulated different nutrient recipes that had shown improved yield compared to commercial products. This ensures the best growth for each crop type. It also reduces common problem stemming from imbalanced nutrient, e.g. leaf chlorosis due to nutrient deficiency. All these translate to a better yield and a more marketable produce for the farmers. Formulations developed include Mizuna, Kale, Lettuce, Mustard, Kalian, and Caixin. The technology provider is seeking for licensing partners from the agriculture industry.

The majority of the local indoor farmers grow crops that are harvested for their leaves. One way to increase the growth rate of such leafy greens is to provide a longer period of light. However, some of the crops grown, e.g., spinach, are long-day plants that flower when the light periods are longer than their critical day-length. While important to a plant’s life cycle, this vegetative to reproductive phase change is undesirable for farmers, not only because it shortens the harvest period hence reducing the yield, but also because it changes the taste profile. To tackle this problem, a light recipe that was able to suppress flowering was formulated. Plants grown under this light recipe showed a faster growth rate than those grown under flowering-suppressing short-day photoperiod. Moreover, they do not flower even when the light period has surpassed the critical day-length. Positive results were obtained when this light recipe was tested on spinach and arugula. This technology would work for other long-day crops, and it will be beneficial to indoor farmers who are interested to try it.

This Internet of Things (IoT) software architecture addresses a decentralized framework to provide the ability to exchange data between IoT devices autonomously without any centralized server. In recent years, the development of IoT applications has become increasingly complex. Thus, this technology addresses the problem by providing the ability to simplify the streaming of data to the IoT platforms over the web. The IoT platform is designed to assist modern-day farmers in monitoring the entire farm seamlessly. It can be customized to suit each farm depending on the type of sensors, machine vision camera, cloud storage, etc. Equipped with detailed data tracking and analytics to provide the most accurate growth process from start to finish. This design can be customized for other applications. The technology owner is looking for partners and collaborators to further co-develop this technology in urban farming.
