Recently, media reports said, the State Quality Supervision, Inspection and Quarantine and the Standardization Administration jointly issued the "soil testing and fertilizer - fertilizer service points technical specifications," the national standard, which will be implemented from November 2, 2015, China The first establish a standard soil testing and fertilizer fertilizer service points, fertilizer and provide guidance services fertilization unified national standard.
According to statistics, since 2004, in balanced fertilization on the basis of the last century, China's agricultural sector-led Fertilization and work has been further developed. In June 2004, Premier Wen Jiabao visited Hubei Province Zhijiang City farmers asked the government to meet their soil testing and fertilization symptomatic, immediately instructed the agricultural sector implement them. In 2005, the Ministry of Agriculture, Ministry of Finance started a pilot soil testing and fertilizer subsidy program, China's new round of soil testing and fertilizer testing officially started.
According to 2014 Ministry of Environmental Protection and the Ministry of Land and the "National survey of soil pollution bulletin" The survey results show that the total national soil exceeding the rate of 16.1 percent points, including mild, mild, moderate and severe pollution point ratio was 11.2%, 2.3%, 1.5% and 1.1%. From pollution type, with no type-based, there are models, followed by a smaller proportion of compound pollution, inorganic contaminants exceeding the point total exceeded the median point of 82.8%.
Some environmentalists analysts pointed out that pollution of the soil in the socio-economic development process of the formation of long-term accumulation. Although soil environmental quality by superposition of multiple factors, but mining and industrial and agricultural production and other human activities and natural background, is the main reason causing soil contamination or excessive.
As a scientific fertilization techniques, soil testing and fertilizer to promote not only effective "measure, with, production, supply, Shi" effective convergence, but also promote a virtuous circle of agricultural land use, soil conducive to the prevention and control.
Fertilization last link in the "formula fertilizer" There are two solutions: one is the great formula in the form of fertilizer, and the other is "now with the current" formula fertilizer. No. GB ​​/ T 31732-2015 of "Fertilization - fertilizer service points technical specifications" national standards is "now with the current" formula fertilizer field, provides space and regional requirements fertilizer service point, equipment and facilities, material control and management, fertilizer process control, quality management requirements and service requirements.
"Fertilization is internationally called balanced fertilization, soil testing and fertilizer technology is the UN [microblogging] in the implementation of the world's advanced agricultural technology." Zhongyu information analyst 郭春荣 in the "China Sankei Shimbun" sermon reporters.
Guo Chunrong said soil testing and fertilizer will not only improve the utilization of fertilizer, but also enhance the ability of soil to retain water and fertilizer, reducing fertilizer costs, improve fertilizer use efficiency. Fertilization is "right", according to the law of crops need fertilizer, soil fertility and soil the size of the development of "feeding", improve soil quality, increase agricultural production yields, reduce agricultural production costs, increase farmers' income, reduce agricultural pollution at the same time protecting the environment, boosting fertilizer zero growth, thereby promoting sustainable development of agriculture.
As for the field of agricultural technology in this regard, analysts generally believe that there is a gap, which, 郭春荣 also hold the same view.
"Our farmers are accustomed to the traditional heavy fertilizer fertilizer, organic fertilizer light; heavy nitrogen, P and K light; heavy macronutrient fertilizer, light trace element fertilizer, not only failed to improve the utilization of fertilizer, they cause soil compaction, acidification, can topsoil area thinning, resulting in the loss of soil fertility. "Guo Chunrong said.
In addition, according to Yu information analysis, results from recent years, soil testing and fertilizer project demonstration area, the corn (2364 -2.00 -0.08%), soybeans (4173 5.00 0.12%), rice and other crops, and fertilizer utilization ratio farmer conventional fertilization acre yield increase over 30kg but also prompted to make fertilizer use efficiency increased by 10%, fertilizer utilization increased by 7% -10%; potassium fertilizer utilization rate above 7%, bringing the advantages of soil testing and fertilizer to promote national active promote soil testing and fertilizer technology.
Earlier, the Ministry of Agriculture, Industry and Information Technology, the National Inspection and Quarantine issued a "speed up the formula fertilizer application view" (the "Opinion") in 2013, which points out that, for the annual fertilizer service capacity in 2 million tons or 2.8 tons per hour, the following small-scale grass-roots intelligence service outlets fertilizer, fertilizer to farmers to buy raw material on the basis of fertilizer, according to farmers Fertilizer blending intelligent, do not enter the market circulation after mixing, are not included in the complex mixed fertilizer production license and fertilizer registration category.
Fertilization bring advantages urge countries to actively promote soil testing and fertilizer technology, not only received a positive response provinces, cities and counties, also opened a soil testing and fertilizer micro-channel service platform.
In this regard, some analysts have pointed out that, due to the compliance of the fertilizer service point no need for fertilizer registration license and industrial production permit, so there are "opinions" will produce a certain extent, encourage enterprises to participate "now mix now with "formulations fertilizer production and operation results, and as previously in the field of soil testing and fertilizer is no uniform national standards, rather vague definition of the relevant technology, not only a waste of fertilizer, but also on the precious soil resources caused damage and pollution, The introduction of national standards, in favor of fertilization rationalization and sustainable use of soil.
