Summary:-

Climate change is one of the greatest challenges of our time and we are steadily marching towards a climate catastrophe. Among the different sectors that fuel climate change through the emission of greenhouse gases (GHGs), the contribution of the agricultural sector is 24%. Unscientific farm management practices such as imprudent use of fertilizers and pesticides, livestock husbandry practices, land use change, etc. are the driving forces that have led to increased greenhouse gas emissions from agriculture. Therefore, strategies to reduce emissions and their subsequent impacts on the changing climate are the need of the hour as agriculture is not only a contributor but also one of the sectors most affected by climate change. Precision Farming or Precision Agriculture (PA) is one such tool that makes farming more “climate smart” more effectively by reducing its impact on the environment. This cultivation technique applies the right management practices in the right place and at the right time, capturing the heterogeneity of the land at the smallest scale. Thus, PA is a technology-intensive system that requires support of the Global Positioning System; various sensors to monitor soil moisture, nutrients, etc. and georeferenced maps for various soil properties, but if deployed on a large scale, they would help improve productivity, increase resource saving and reduce environmental impact. PA is the modern climate-friendly agriculture strategy that could solve the problem of food shortages in developing countries and turn out to be an effective tool as well as a solution to the myriad challenges facing the agricultural sector.

Deploying IoT in agriculture and farming practices is the need of the hour as the world population is set to peak at 9.6 billion by 2050 to meet this type of demand that the agribusiness needs to deliver even faster. This is made possible by the use of modern technology and above all IoT. IoT makes work-free farms possible. Not only in large farming practices, but also in keeping livestock, greenhouse cultivation, managing farms, etc. The most important tool for the IoT are sensors. Sensors are devices that collect important data that is interpreted to get the analysis you want. In agriculture, sensors are mainly used to obtain readings used to measure NPK levels, disease detection and soil moisture levels. This paper examines its application in agriculture. Smart farming is called precision farming because it uses precise data to draw conclusions. It shows the different sensors supporting IoT and agriculture, their applications, challenges, advantages and disadvantages.
