“India's agriculture is its lifeline.” The production of agriculture depends on fertilisers. One of the main issues that farmers face is a lack of information regarding the necessary fertiliser amounts. Farmers think that when fertiliser use rises, production rises as well. This, however, is untrue since the soil just uses what it need and leaves the remainder behind. Overuse results in leaching, a decrease in the natural fertility of the soil, and other problems. A solution is to make it possible for farmers to test their soil and use fertilisers in accordance with the needs of the soil at a reasonable cost. This study describes the development of a low-cost soil nutrient detection method using pre-made capsules. Here, it is possible to do three different nutritional tests for sodium, potassium, and phosphorus. In this experiment, three test tubes are used, and after adding varied amounts of dirt and water to each, the mixture is stirred for 15 minutes. After then, the tube starts to change colour. A colour sensor is used in this instance, and it recognises the colour shift in the test tubes and compares it to the information previously known about the colour deficit. The farmer is advised of the shortage and how much fertiliser is necessary to make up for it once the sensor data is analysed using Arduino.

For crop optimization and protecting plants from environmental toxins, soil testing is essential. Farmers are frequently urged to submit soil samples for testing to labs. Although a laboratory soil test has several benefits, there is a longer wait for the findings. Petrochemical sensors are also used to examine soil nutrients. It can detect soil nutrients using ion electrodes although real-time sensing implementations are not possible because of the execution latency. Because they are generally more costly and larger, petrochemical sensors are the least cost-effective for farmers.
