4. the nature of the problem with coated fertilizer capsules is not so much a risk issue as it is a garbage issue<\/h3>\n\n\n\n

\u3000Considering that the current ecological risk is below the level of concern and that coated fertilizers are a minor source of microplastic emissions, as we have summarized, discontinuing the use of coated fertilizers as a microplastic risk reduction measure would be very inefficient. If the use of coated fertilizer is discontinued and repeated fertilizer application is considered, it is necessary to consider that fertilizer efficiency will be reduced and the amount of fertilizer dropped will increase, and that repeated field trips for fertilizer application will increase other risks due to vehicle use (tire wear is a top source of microplastic emissions). . Increased fertilizer drops can also cause other environmental problems, such as eutrophication of water systems and greenhouse gas emissions from denitrification. Thus, discontinuing the use of plastics alone will not solve the problem.<\/p>\n\n\n\n

\u3000In 2022, JA Zen-Noh and industry associations released a \"Policy for Efforts to Prevent Marine Discharge of Plastic Coated Shells of Slow-release Fertilizers\". The policy outlines the following three initiatives to be achieved by 2030:<\/p>\n\n\n\n

(1) Publicize the presence of plastic in coated fertilizers
(2) Implementation of measures to control runoff of plastic-coated shells from agricultural land
(iii) Realization of agriculture that does not rely on plastic coating through the development and diffusion of new technologies<\/p>\n\n\n\n

1. an era in which plant nutrients are changing from organic to inorganic<\/h3>\n\n\n\n

\u3000In 1828, Sprengel of Germany was the first to question this common theory and point out that plant nutrients are not organic but inorganic (minerals). It was Liebig, also of Germany, who further supported his point of view and popularized the theory in 1840. It was during this period that Rose marketed an inorganic chemical fertilizer (a patented fertilizer composed of lime superphosphate, ammonium phosphate, and potassium silicate) as a nutrient for crops.<\/p>\n\n\n\n

\u3000Rose attempted several trials in his hometown of Rothamsted, Harpenden, to verify the efficacy of the chemical fertilizers he intended to sell. He conducted pot trials in 1837-39 and small field trials in 1840-41. From these trials, he recognized the importance of phosphorus as a nutrient for cabbage, since the highest yields were obtained when cabbage was treated with ammonium phosphate, which contained phosphorus as well as nitrogen.<\/p>\n\n\n\n

2. overview of broadbore wheat field trials<\/h3>\n\n\n\n

\u3000Rose brought in Gilbert, who had studied chemistry at Liebig's, as a scientific collaborator and began comparing the nutrient effects of chemical fertilizers and compost. It was in the fall of 1843, the very same year that chemical fertilizers were introduced to the world, that he sowed wheat (fall-sown wheat) as a crop for testing. This is the Broadbark wheat test plot introduced this month. The year 1843 was the founding year of the Rothamsted Agricultural Experiment Station.<\/p>\n\n\n\n

3. results of broadbark wheat field trials<\/h3>\n\n\n\n

\u30001) Yield equivalent to composted area with appropriate amount of chemical fertilizer<\/h4>\n\n\n\n

\u3000Figure 1 shows the results of this trial. The yield of wheat seedlings in the chemical fertilizer (N144 kg\/ha) area of the continuous wheat test was not much different from that in the compost area. It was confirmed that the production of wheat seedlings with chemical fertilizer alone was almost equal to that with 35 t\/ha of compost, if the amount of fertilizer applied was appropriate.<\/p>\n\n\n

\n
\"\"<\/figure><\/div>\n\n\n

\u3000Interestingly, after 60 years of continuous cropping, in 1902, both treatments showed continuous crop failure and yield decreased. When the fallow treatment was introduced (one-year fallow followed by four-year row cropping), yields recovered again. This indicates that the continuous cropping failure of wheat occurs not only in the chemical fertilizer area but also in the compost area, and that the fallow treatment is more effective for recovery than the nutrient treatments such as compost or chemical fertilizer.<\/p>\n\n\n\n

(2) Dramatic increase in yields with the introduction of high-yielding varieties<\/h4>\n\n\n\n

\u3000Since 1968, when high-yielding varieties were introduced, the yield of row crops of wheat has nearly doubled, despite no change in compost or chemical fertilizer application treatments. This confirms the high seed production capacity of high-yielding varieties.<\/p>\n\n\n\n

\u3000Furthermore, in the five-year crop rotation established after 1968, when the nitrogen content of chemical fertilizers was added to the compost to increase the total nitrogen application, the yield was nearly 10 t\/ha. This is not only about three times the yield of the composted area in the old variety era until 1967, but also about twice the average yield in Japan. The effect of the addition of chemical fertilizer nutrients to the compost is clear, and the high-yielding variety's response to fertilizer nutrients is understandable.<\/p>\n\n\n\n
