In recent years, we've seen strong linear growth in U.S. crop yields, driven by incremental technological improvement. But several nascent technologies could combine to produce a compounding effect on future crop yields, which could drive higher valuations for farm properties.
As global populations surge and issues such as water scarcity and climate change potentially become more acute, it is clear that the need to boost crop yields in a sustainable manner is paramount. Technologies that hold the potential to transform the agricultural landscape include improved fertilizer production methods, precision agriculture, genetic engineering, vertical farming, and even artificial intelligence (AI).
Commercial fertilizers, chemical compounds that facilitate plant uptake of Nitrogen, Phosphorus, and Potassium, are enabling technologies for increasing crop yields. The production of ammonia, a crucial ingredient in nitrogen fertilizers, which are responsible for vegetative growth as distinct from root mass or flower production, has traditionally relied on the Haber-Bosch process. Despite its widespread usage, this method is energy-intensive and significantly contributes to greenhouse gas emissions. However, a groundbreaking alternative called the Nitrogen Reduction Reaction (NRR) is emerging as a more efficient and eco-friendly solution.
The NRR process leverages lithium as a catalyst to reduce nitrogen (N2) to ammonia under ambient temperature and pressure, a procedure known as nitrogen fixation. Recent advancements in this area have boosted the process's yield and efficiency up to 100 times, rendering the NRR a more viable alternative to the Haber-Bosch process, which is credited with up to 60% of crop yield increases since inception.
Whereas current nitrogen fertilizer production must be centralized due to energy and physical constraints in production, this innovation could enable farming operations to produce nitrogen fertilizers locally, in discrete amounts for specific applications, thus increasing efficiency in crop yield improvement. This is particularly impactful in the U.S., where natural gas, a key input for nitrogen fertilizer, is relatively cheap and abundant.
Precision agriculture presents a way to manage crops more effectively by utilizing data and technology. Using sensors, farmers can monitor soil moisture and nutrient levels, enhancing irrigation and fertilization practices per plant, based on real-time data.
Drones and GPS also play a crucial role in surveying fields precisely to monitor crop health and identify potential issues before they escalate to impact crop yields significantly. These practices optimize crop productivity, contribute to sustainable agriculture, and may consequently increase the value of the farmland on which crops are grown.
Genetic engineering offers an avenue to directly modify the genetic makeup of crops, bolstering traits such as yield, pest resistance, and drought tolerance. Herbicide-resistant crops, developed through genetic engineering, can help farmers increase crop yields, yet reduce chemical usage, contributing to sustainable farming practices while also addressing issues of water scarcity and climate change.
As urban spaces continue to expand, vertical farming is gaining traction as a means to grow crops in vertically stacked layers within controlled environments.
By taking advantage of vertical space, this method allows for high-density vertical farming, even in urban areas where land is scarce. Vertical farming can help bolster crop yield productivity while reducing the environmental impact of agriculture, an essential aspect of climate change mitigation.
Hydroponics—the practice of cultivating crops in a nutrient-rich water solution rather than soil—is another technique reshaping agriculture. Offering the ability to grow crops in various environments, including indoors, outdoors, or in remote areas, hydroponics can help enhance vertical farming as well as address water scarcity by using water more efficiently than traditional soil-based farming.
The method reduces the risk of pests and diseases, contributing to increased crop yields and potentially driving the value of property used for hydroponic vertical farming operations.
Artificial Intelligence (AI) holds great promise for revolutionizing farming practices. By automating tasks such as crop monitoring and pest identification, AI enables more precise and efficient farming.
AI can enhance the agricultural sector crop yields by aiding in the creation of new crop varieties, optimizing farming practices, and seamlessly integrating other technologies. This advanced, overarching application of artificial intelligence can potentially compound the value of farm properties more quickly than historical growth rates imply by enhancing crop yields through the general application of intelligence.
The agricultural sector stands at the brink of a technological revolution. Innovations such as the NRR process for fertilizer production, precision agriculture, genetic engineering, vertical farming, hydroponics, and their combination with AI promise to boost crop yield productivity, enhance sustainability, and combat the challenges posed by climate change and water scarcity.
As these technologies become more prevalent, their effects will inevitably impact the value of agricultural property, and the operations of vertical, hydroponic, and aquaponic farms, reshaping the agricultural landscape with enhanced crop yields for a more sustainable and profitable future.
