How about the effect of reducing the amount of fertilizer and pesticide

The latest data from the Ministry of Agriculture and Rural Affairs shows that the use of chemical fertilizers and pesticides in China has seen negative growth for five consecutive years. In 2021, the comprehensive utilization rate of crop straw, agricultural film recovery rate and livestock and poultry waste are expected to exceed 88 percent, 80 percent and 76 percent, respectively, up 0.4, 1 and 1 percentage point over the previous year.In recent years, the state has vigorously promoted the green development of agriculture.The zero growth of fertilizer campaign is an important one.The reporter interviewed Jin Shuqin, a researcher at the Rural Economic Research Center of the Ministry of Agriculture and Rural Affairs.According to the report, China’s fertilizer use from 60.22 million tons in 2015 to 52.5 million tons in 2020, a drop of 12.8%;Fertilization intensity decreased from 369.9 kg/ha to 313.5 kg/ha.Compared with the 12th Five-Year Plan period, the amount of chemical fertilizer used in the 13th Five-Year Plan period has been reduced by 13.22 million tons, effectively curbing the worsening trend of agricultural non-point source pollution.In 2021, agricultural and rural departments will reduce the amount of chemical fertilizers and increase their efficiency, revise and release industry standards to regulate the production and use of organic fertilizers.At the same time, technical guidance on scientific fertilization was strengthened, and the recommended application amount of nitrogen fertilizer for major crops in different regions, crops and yield targets was clarified to facilitate accurate fertilization.”Nevertheless, some members of the public still have doubts about fertilizer reduction and feel there is a discrepancy between the reduction data and the perceived effects.”Jin shuqin said there are two reasons for the difference.On the one hand, the national fertilizer and pesticide reduction target is global, but it may be implemented in the grassroots layer by layer, and the central environmental inspectors have repeatedly pointed out that some local fertilizer reduction data are inaccurate.On the other hand, the main force of “reducing weight” is the new type of agricultural business entities, but in terms of the number of agricultural business entities in China, small farmers account for 98%, and large-scale households only 2%.Ninety-eight percent of small farmers only cultivate 70 percent of the land, and quite a few of them entrust social services to organize fertilization and medicine.In other words, there is a large proportion of small farmers, but their actual use of fertilizer is not that large.”The above two aspects can reflect the inaccurate data and insufficient coverage of chemical fertilizer reduction, but it is not enough to deny the objective fact of total reduction of chemical fertilizer.”Jin shuqin said that in recent years, a series of measures have been taken, such as substituting organic fertilizer for fruit, vegetable and tea, promoting the utilization of livestock and poultry waste in the whole county, and expanding the coverage of soil testing formula, which will objectively reduce the amount of fertilizer.In 2020, the utilization rate of fertilizer and pesticide for rice, corn and wheat was 40.2 percent and 40.6 percent, respectively, 7.2 and 5.6 percentage points higher than that in 2013. Absorption efficiency has improved, and input has naturally decreased.Jin shuqin said that in the next step, while consolidating the existing achievements, to achieve green development in line with the public perception, we need to continue to make efforts in three aspects.In the past, we should shift from promoting the reduction of single factors of production and the use of resources to promoting green development in a comprehensive and systematic way.Greening is regarded as the core content of promoting agricultural and rural modernization in the new period, which is implemented in all aspects. For example, the industrial system should pay attention to the proportion of planting and breeding industry, and the mechanization should pay attention to the energy saving and consumption reduction of agricultural machinery.At the same time, the policy focus in addition to new agricultural operators to pay attention to small farmers, in addition to economic crops also attaches great importance to the field crops, vigorously promote cultivated and circulation, in the industry pattern between cultivated and subject, regional internal, multi-dimensional formed between regional cultivated and combine, making 4 billion tonnes of livestock waste nitrogen of 2 billion mu of arable land.In addition, it is necessary to establish and improve agricultural resources and environment ledger.Make great efforts to find out the bottom of the family, use big data technology to obtain information on the production, sales and use of inputs such as fertilizers, pesticides and agricultural film from multiple sources and multiple caliber, and master the production, use and discharge of agricultural residues such as straw and manure, so that the decision-making of agricultural green development can be based on data and the effects can be verified.
