Abstract
Agriculture is basis of livelihood for a major portion of world population. It provides food to humans. With the increasing population and climate change there is need to enhance production to fulfil the demand of growing population. Remote sensing technology has potential to predict nutrient requirement by providing various information related to plant and soil in quantitative terms thereby increasing productivity. It plays important role in monitoring crop health, crop growth and development, nutrient management, pest and disease management, water management and weed management. Evaluation of crop canopy provide various information regarding agronomic parameters. The data obtained from remote sensing provides a better alternative for natural management than traditional methods and this kind of management enhances efficiency of various resources by avoiding their overuse. By using this technology, we can improve traditional methods of agriculture and bring out changes in the field of agriculture. This paper reviews remote sensing technology for crop health monitoring, highlighting its importance with new ideas for agriculture.
