Abstract:
Soil fertility management has remained a static affair consisting of a blanket application of plant nutrients irrespective of soil fertility status and specific crop requirements. More often farmers apply the fertilizer of their choice in their own way without considering the importance of soil tests or any scientific basis before deciding upon the quantity and quality of fertilizer. Realizing the huge gap between a Farmer’s Fertilizer Practice and the actual requirement of fertilizer based on crop requirement and nutrient status of the farm, an experiment was carried out to test the potential yield and quality enhancement by application of a required amount of nutrients taking tomato as test crop. For this purpose, a precise IoT-based instant and in-situ soil testing system with crop-specific fertilizer requirement decision was used. The present-day concern for hazards due to the use of chemicals was also taken into account. Therefore, the experiment was set up completely under an organic system. The precision of the IoT-based system in recommending crop and site-specific nutrients was reflected in the highly significant yield and quality aspects of tomato grown as per its recommendation.
