Precision Agriculture, also known as smart farming or precision farming, is a modern data-driven farming technique that collects and analyzes field data by using technology and optimizes crop production to improve its efficiency. The main aims of Precision Farming or Precision Agriculture are to increase productivity, decrease production costs, and minimize the environmental impact of farming. Smart farming is important as it helps tackle agricultural production challenges in terms of productivity, environmental impact, food security, and sustainability.

Precision Agriculture uses a wide range of tools and techniques to collect big data, analyze it, and make informed decisions about managing crops, soil, and resources like water and fertilizer. It is based on the idea that different parts of the agriculture field have different needs. When each of these parts is treated individually, farmers can maximize yields while minimizing inputs like water and fertilizer. It involves several technologies to monitor and manage fields in real time, making changes as needed to optimize crop growth and health.

How does precision agriculture work?

Precision agriculture uses various equipment, software, and services to access real-time data about crop conditions, soil, weather conditions, and equipment availability. Real-time data is collected by using various sensor technologies in the fields that measure the temperature, and moisture of the soil and surrounding air. It also utilizes various satellite and drop images that provide high-quality images with Normalized Difference Vegetation Index(NDVI) data.

How is Precision Agriculture dependent on Technology?

Technology is at the heart of precision agriculture. It allows farmers to collect, analyze, and act on data in ways that were not possible before, leading to more efficient and sustainable farming practices. There are many different technologies used in precision agriculture. They are listed below.

Data Collection: Several technologies are used to collect a wide range of data like geospatial data, and historical datasets (land characterization and crop phenology, rainfall and temperature, elevation, global tree cover maps) from the agricultural field including moisture levels, temperature, humidity, and more. This data is then used to make informed decisions about farming strategies.

Remote Sensing: There are remote sensing technologies such as drones, satellites, synthetic aperture radar, and airplanes that monitor fields from a distance. These technologies can be used to collect data on crop health, soil moisture, and more, which can then be used to make informed decisions about how to manage the field. This also allows farmers to get a bird’s eye view of their fields and identify areas that need attention.

Global Positioning System(GPS): GPS is used to map fields and track the location of the machinery and equipment. This allows farmers to create detailed maps of their fields, which can be used to plan planting and harvesting. This technology allows monitoring the health of crops as well.

IoT and Sensors: The Internet of Things (IoT) plays a big role in precision agriculture. There are various sensors like camera sensors and ground sensors placed in fields that monitor conditions like soil, moisture, temperature, salinity, electrical conductivity, moisture, and pH levels in real-time. These sensors can then communicate with other devices to automatically adjust irrigation or fertilizer levels. These data points allow farmers to make decisions about when and how much to water and when to apply fertilizers.

Automated Machinery Equipment: Precision agriculture often involves automation of tasks that used to be done manually. Automated machinery, such as self-driving tractors and drones, can be used to plant, water, and harvest crops with extreme precision. This reduces waste and ensures that crops receive exactly what they need.

Machine Learning and AI: Machine learning and AI algorithms are used to analyze the data collected from the field and provide insights. Some of these algorithms are image processing, statistical analysis, spectral matching techniques, reflectance, and surface temperature calculations from the collected data. This can help farmers make better decisions about when to plant when to harvest, and how to manage pests and diseases.
