It can help farmers increase yield, quality, and profitability, while saving water, energy, and labor. But what are the advantages and limitations of precision agriculture, and how can it integrate with other emerging technologies such as AI, IoT, and blockchain? In this article, we will explore these questions and provide some examples of how precision agriculture is transforming agribusiness.
What is precision agriculture?
Precision agriculture is the application of information and communication technologies (ICT) to agriculture. It involves collecting, processing, and analyzing data from various sources, such as soil, weather, plants, pests, and markets, to make informed decisions about crop management. Precision agriculture also uses automation and robotics to perform tasks such as seeding, fertilizing, irrigating, harvesting, and grading. Precision agriculture aims to tailor the inputs and outputs of farming to the specific needs and conditions of each field, plot, or plant.
What are the advantages of precision agriculture?
Precision agriculture offers numerous benefits for farmers, consumers, and the environment. It can improve efficiency and productivity by optimizing the use of resources like water and fertilizer, while also enhancing the quality and profitability of crops. Additionally, precision agriculture can help reduce environmental impact by minimizing greenhouse gas emissions, soil erosion, water pollution, and biodiversity loss. For instance, precision irrigation can reduce water consumption by up to 50%, while precision spraying can target weeds and pests with minimal collateral damage. Precision harvesting can detect optimal ripeness and size of fruits and vegetables, while precision mapping can identify and protect sensitive areas. All of these practices can help increase the value and profitability of produce. A large component of the value is also about optimizing the farmers business. Crop production inputs are a huge expense. Constant-rate applications add to field variability whereas variable-rate plus on-off prescription applications reduce field variability and maximize economic outcomes. While these technologies offer the benefits listed, I don't believe the consumer will pay more for food produced via better technology. It's the farmer that will have to pay. So should governments pay farmer to use resources better to help protect the environment?

What are the limitations of precision agriculture?
Precision agriculture has its challenges and limitations, such as a high initial cost and maintenance due to the hardware, software, and infrastructure needed. Data availability and quality is also an issue, as it can vary depending on the location, season, and crop. Furthermore, precision agriculture requires a high level of technical and analytical skills from farmers, which many may not have. Additionally, some farmers may face social, cultural, or ethical barriers to changing their traditional practices and mindsets. All these factors can contribute to the operational cost and complexity of farming, as well as limit the sharing and integration of information among different stakeholders.
There are no social, cultural, or ethical barriers, but the return on investment to the farmer is slim. Often the cost is too high, as mentioned but the impact is too low. Even with high input cost we are seeing at the moment isn't enough to see farmers take a fresh look at precision ag.

How can precision agriculture integrate with other emerging technologies?
Precision agriculture can be greatly enhanced through the integration of other emerging technologies such as artificial intelligence (AI), internet of things (IoT), and blockchain. AI can enable precision agriculture to use machine learning, computer vision, natural language processing, and other techniques to process and analyze data sets, generate insights and predictions, and automate decision making and actions. IoT can enable precision agriculture to connect with a network of devices, sensors, and actuators that collect and transmit data in real time, and control and coordinate operations remotely. Blockchain can enable precision agriculture to store and share data securely and transparently, as well as facilitate transactions and contracts among various parties in the agribusiness value chain. For instance, AI can help farmers diagnose crop diseases, optimize crop rotation, forecast crop yield and demand; IoT can help farmers monitor soil moisture, adjust irrigation levels, activate sprinklers automatically; blockchain can help farmers track and verify the origin, quality, and safety of their produce, access financing and insurance services.
