Vertical Farming using Smart Farming

Abstract

Nutrient content (Nitrogen, Phosphorous, Potassium) monitoring in soils is essential for the proper use of fertilizers to minimize the environmental impact of wrong pattern fertilization practice. Collecting samples from different locations and laboratory testing takes longer and costs a lot. New-generation digital sensors are smart enough to replace chemical lab testing in real-time with minimum effort and with almost precise results. The Proposed system tends to implement various suggestions that would also help improve the quality of the work being done by the soil testing laboratories. By this, we can able to test our soil parameter in that condition quickly in our field for further processes and we will get the soil parameter report without any delay. And we can get information about the fertilizer and crop matches for that result and the number of fertilizers to be used. And to demonstrate soil humidity sensors and pH sensors to measure the NPK values which determine the fertility of the soil, which helps to improve cultivating system. The results obtained from our developed sensing system are almost accurate and very close to the laboratory test readings. Arduino plays a key role in processing data received from the sensor as input, the counters used here produce the respected output values for the parameters. There the values received by the Arduino are compared with the database and provide related information which is matched to the current calculated values. The output values provided by the Arduino and sensors will be displayed on the LCD. Here the output not only provides formation on fertility present in the soil but also suggests crops to be grown on that soil.
