Traditional farming has imbalance and excess use of chemicals and, in turn, to negative environmental impacts on soil health, groundwater, and atmosphere. Sensor based farming system should be more sustainable to reach economical and social profitability as well as the sustainable environment. A correct solution is to adopt precision farming, the best option for sustaining food production without declining the ecosystem. Precision technologies are used for integrating information about spatial and temporal differences within the field in order to match inputs to site-specific field conditions. The aims are to perform an investigation both on approaches and results of site-specific N management in wheat crop and to analyse performance and sustainability of agricultural practice. The earlier creation N management decisions, both the measurement and understanding of soil spatial variability and the wheat N status are needed. Complementary use of different sensors has improved soil quality relatively low cost. The red edge and near-infrared bands can penetrate into higher vegetation fraction of the canopy. | Sensor based N management practices for wheat in Indo Gangetic plain - A review
