Making digital soil health maps for each farm without touching the soil.

As India strives to become a global leader, the looming threat of soil degradation poses a major challenge to its agricultural backbone. According to the National Bureau of Soil Survey and Land Use Planning, 30 percent of India’s soil, a total of 146.8 million hectares, has already been degraded. If not addressed quickly, this could have serious consequences for food security and the livelihoods of millions of people. Despite technological advances that increase food production, soil degradation requires urgent attention through a combination of policy measures and innovative solutions.

The State of India’s Soils

Statistics reveal a grim reality – 29 percent of degraded soil goes into the sea, 61 percent . is translocated and 10 percent settles into reservoirs. Although India is the world’s second largest producer of agricultural products, self-sufficient in its food production, the long-term outlook is worrisome. India’s 2.4 percent of the world’s land area has to feed 18 percent of the world’s population. Soil degradation threatens the economic, environmental and health dimensions of the country and requires immediate action.

Digital Agriculture

In the era of digital agriculture, farmers are adopting technology to improve yields and operations. Digital soil health maps have become an important tool for this change. These maps provide comprehensive information about soil health, including nutrient levels, pH and organic matter content. The data allows farmers to make informed decisions about fertilizer use, irrigation and general farm management practices.

Development of soil test methods

The traditional soil test method, which involves sampling and laboratory analysis, has faced its limitations. However, with the advent of technology, especially the Internet of Things (IoT) and satellite-based soil testing, a new era of effective and transformative soil health assessment has emerged. Laboratory-based soil testing has been around for a long time. time time as a benchmark of accuracy. Although reliable, it costs both time and money. While the complex process is valuable, it is not always practical for farmers looking for real-time information about soil health. IoT-based testing puts sensors directly into the soil. These sensors collect dynamic data on nutrient levels, pH and moisture content. The real-time data is then wirelessly transmitted to a cloud-based platform that enables the creation of a comprehensive digital soil health map. This method not only saves valuable time but also provides farmers with practical knowledge for timely action.
