The reliance of modern agriculture on fertilizers and chemicals can not be underestimated. Indeed, fertilizers and chemicals are commonly used for soil and crops to keep cultivated crops healthy and provide them essential elements for crop development. Use of fertilizers and chemicals directly influence crop productivity, however over usage of agrochemical inputs can significantly damage the soil and environment. On top of that, the costs of chemicals on average represent about 30-40% of total operating expenses for major commodity crops. All that highlights that chemical use efficiency is a critically important concept in the evaluation and improvement of crop productivity.

The application of hyperspectral imaging in agriculture can significantly improve chemical use efficiency and reduce damages to the environment. Gamaya, a Swiss AgTech company active in smart farming, provides a comprehensive solution for large-scale monitoring and diagnostics of farmland based on hyperspectral imaging (HSI) technology. In order to address the question of chemical use efficiency Gamaya performed a field trial, where we analyzed a number of small plots with different chemical regimes. Hyperspectral image below shows multiple research plots, that has been treated using different chemicals and chemical regimes. You can clearly see the difference, represented by a variety of colors. Having information about crop performance and yield we can assess the efficiency of different chemical regimes. This is possible due to very high spectral sensitivity of the hyperspectral camera for uav application developed by Gamaya, which is deeply integrated with our data processing algorithms and analytical software.

Our product decreases chemical usage and associated expenses by 30% due to the optimum distribution of agrochemical inputs. On top of that, we help industrial farmers to improve their crop yield without increasing use of chemicals and damage to the environment. We help our clients to grow better and more!
