What are the disadvantages of traditional modern agriculture?
Increase resource consumption. Because a characteristic of modern agriculture is mechanization of operation, coupled with the input of chemical fertilizers and pesticides, it needs to consume a lot of fossil energy, so some people call modern agriculture "petroleum agriculture". According to "Analysis of Agricultural Dynamics" written by F 1u, American agriculture consumes 7. 1.4kJ of petrochemical energy for every food energy produced 1.0kJ (including 0.62kJ of plant food energy and 0.38kJ of animal food energy), of which 1.4kJ is used for crops.
In essence, agriculture is an industry that uses solar energy. However, modern agriculture relies too much on the input of petroleum, fertilizers and pesticides, which makes the grain production process a process of exchanging chemical energy such as petroleum for grain energy. So it can be said that the road of petroleum agriculture deviates from the essence of agriculture. At the same time, because energy resources such as oil, coal and natural gas and fertilizer resources such as phosphorus and potassium are non-renewable resources in the world, a large amount of consumption will inevitably accelerate the process of exhaustion of these resources. Furthermore, because modern agriculture is based on cheap resources, once there is a resource crisis, the blow to modern agriculture will be immeasurable.
