Dynamic monitoring of crop growth, agricultural remote sensing technology can know the growth status, seedling condition, soil moisture, nutritional status and its changes of crops in time through dynamic monitoring of crop growth, which is convenient for taking various reasonable management measures to ensure the normal growth of crops.

Remote sensing monitoring of crop diseases and insect pests, for a long time, sampling field investigation at the field level of crops has been the main means to identify and monitor diseases and insect pests, which has played an important role in forecasting diseases and insect pests and formulating reasonable control strategies.

Crop yield estimation by remote sensing. In 1980s, China carried out the research on comprehensive yield estimation of winter wheat by remote sensing using Landsat data, and then established the "Dynamic Monitoring and Yield Estimation System of Winter Wheat by Meteorological Satellite Remote Sensing in North China", which laid the foundation for the research and development of key remote sensing technologies and practical systems in the future.
