DOTS’ (Data of the Soil) innovative technology provides affordable, real-time, in-situ measurements of nitrate concentration across the soil profile. DOTS solution enables farmers to reduce fertilizers application and increase profits and crop productivity while preventing environmental pollution. Common fertilizing practices derive farmers to waste at least 40% of their fertilizer application with a cost damage of up to $1,250 per Hectare annually, due to the current lack of monitoring technologies for real-time measurements of soil fertilizer state. DOTS is addressing this significant unmet technology gap in the agriculture industry and provides a new horizon for the reduction of agricultural environmental footprint. DOTS’ innovative and patented technology enables precision farming that continuously measures the soil nutrient status. It combines novel electro-optical methods with state-of-the-art soil monitoring techniques, for comprehensive, affordable, and precise multi-depth N-fertilizer measurements.
