FarmCorder - Crop Nutrition Deficiency Sensor

Farming remains to be backbone of developing countries like India and Africa and it is the principal source of livelihood for majority of the population in the countries. Farmers however, use antiquated techniques which lead to overuse or under usage of fertilizer,water which leads to disastrous yields. Our solution to this problem is “FarmCorder” system. We propose a new simple and intuitive sensor based system which consists of base hand held module. The leaf nutrients are measured by leaf probe which works by multi-spectral spectroscopy. The soil moisture probe which works by capacitive moisture sensing. The data logging is performed by a low power micro-controller and data is sent to a remote server with GPS coordinates via a GSM module where the data is processed and appropriate fertilizer advice is provided. It was late summer in my hometown and I visited my dad’s village farm during my university break, I found my dad to be perplexed in the field jotting down something on his notebook. Upon inquiry I learned that it was time for fertilizer application in his rice crop and that he was finding it difficult to find out how much fertilizer to apply for his crop. I had heard of the recent surge in fertilizer cost but I was surprised to hear that it was causing him quite a bit of capital investment and that the amount had to spot on. I found the problem to be a bit odd and I wondered if anyone had come up with a solution to solve this rather giant problem. A visit to a nearby Agriculture research facility made me realize the magnitude of the problem and the wide array of farmers whose very livelihood was affected by the same.This sort of inspired me to come up with a solution to make not only my dad’s job easy but also aid all small farmers in developing nations.”
