| Chemical fertilizer reduction is the key to control non-point source pollution and promote rural ecological revitalization and agricultural sustainable development. It is found from the literature at home and abroad that phenomenon of excessive fertilizer application in China is common and reduction potential is large. As the main users of chemical fertilizers and participants in environmental pollution prevention and control, farmers are lack of awareness of this phenomenon, which increases the risk of environmental pollution. Furthermore, factors influencing the willingness and behavior of farmers to reduce fertilizer use include farmland characteristics (such as farmland resource endowment, farmland circulation and management), social-economic environment (such as machinery use, technical training), individual family characteristics, farmers’ cognitive level and risk attitudes, etc. With the gradual improvement of agricultural land transfer market in China, emergence of new agricultural business entities such as family farms, new technologies such as soil testing and formula fertilization as well as organic fertilizer substitution for chemical fertilizer, dynamic changes of farmers’ behavior and willingness can be further explored from the perspective of time vertical or regional horizontal so as to guide farmers to reduce fertilizer input and realize sustainable development of agriculture. |
