What is precision fertilization & precision irrigation?
Precision fertilization and precision irrigation use remote sensing and telemetry technologies to accurately grasp the spatiotemporal differences in soil, water, fertilizer, diseases and insect pests, and crop yields, which maximize the economic and ecological benefits with minimum production input [ 36 ].
What problems should be solved in China's implementation of precision fertilization & irrigation?
Low-cost technological achievements and supporting key technology and equipment of precision fertilization and irrigation are urgent problems to be solved in China’s implementation of precision fertilization and irrigation. (3) A national unified agricultural data center and information platform should be created.
How are information management and decision-making systems used in precision fertilization & irrigation?
The above technologies are used to collect information on crop survival environments and growth conditions for grasping the dynamic changes in crop growth and using the information rationally. Information management and decision-making systems are at the heart of precision fertilization and irrigation.
How can remote sensing technology improve fertilization and irrigation decision-making?
High-precision, real-time remote sensing imaging technologies, such as UAV and 3D laser scanning, are introduced to provide more accurate and powerful technical support for precision fertilization and irrigation decision-making services [ 26, 27, 28, 29, 30 ].
