Advantages of Drip Irrigation Fertilization Compared to Conventional One
Compared to conventional fertilization methods, drip irrigation fertilization system has the following advantages.
Labor saving
In the production process of fruit trees, water and fertilizer management requires a large amount of manpower. For example, in some banana producing areas in South China, the number of annual fertilization is up to 18 times. Dig holes or open shallow trenches for each fertilization, and irrigate after fertilization. By utilizing facilities for irrigation and fertilization, water and fertilizer are managed simultaneously, saving a lot of labor. Nowadays, labor prices are becoming increasingly high, and the application of irrigation and fertilization technology can significantly save production costs.
Beneficial for environmental protection
China currently ranks among the world's top in terms of fertilizer application per unit area. The utilization rate of fertilizers is relatively low. Due to unreasonable fertilization, there is a great waste of fertilizer. A large amount of fertilizer is not absorbed by crops and enters the environment, especially the water body, resulting in Eutrophication of Rivers and Lakes.
By controlling the irrigation depth through drip irrigation, it is possible to avoid the leaching of fertilizers into deep soil, resulting in soil and groundwater pollution, especially the leaching loss of nitrate nitrogen, which can be greatly reduced.
