\u3000Long's new fertilizer design manuals have been devised and disseminated nationwide through fertilizer efficacy tests and extension trials tailored to the growing conditions in each prefecture for many crops. In fruit and vegetable crops, where nutritional and reproductive growth occur simultaneously, fertilizer application is an important technology for achieving high quality and high yield, because it is necessary to determine the timing and amount of nutrient fertilizer application by watching the fruit development process.<\/p>\n\n\n\n

\u3000Based on the excellent nutrient supply performance of Long, a system of fertilizer application with emphasis on the primary fertilizer has been developed to simplify the fertilizer application technique. The examples of fertilization designs shown in Table 7 are based on the application of Long as the base fertilizer, with an appropriate amount of additional fertilizer applied according to the growth conditions of the crop. While the total basal application system is widely used for paddy rice, most of the fruit and vegetable crops, which require a longer growing period, have a basal application plus additional fertilizer system, in which fertilizer is applied while watching the crop's face.<\/p>\n\n\n\n

\u3000The longs used in the fertilizer design are diverse, with the brand and type selected in accordance with the local fertilizer application system. There is also a shift to a total source fertilization method using longs and a progressive fertilization method in which longs are used for additional fertilizer.<\/p>\n\n\n\n

\u3000Although a lot of test data has already been accumulated for long and high control, the \"Long and High Control Test Data Collection,\" which consolidates the test results published since 2009 in the categories of \"Fruits and Vegetables,\" \"Leaf and Stem Vegetables,\" \"Root Crops,\" \"Fruit Trees,\" \"Flowers and Trees,\" \"Craft Crops,\" and \"Forestry and Containerized Seedlings,\" has been compiled by JCAM Agri Co. The data is compiled by JCAM Agri Co. According to the data, root zone fertilization methods for various crops in the horticultural field have recently been studied, and long-high control has been taken up.<\/p>\n\n\n

(1) Long cultivation of healthy paddy rice seedlings<\/h4>\n\n\n\n

\u3000The \"field nursery\" method, which is superior in rooting ability, has been used in paddy rice seedling cultivation methods. In cold regions, it is known that seedling vigor after transplanting affects seedling yield, and a new method was developed to grow seedlings with 50 to 100 g of Long 424-100 fertilizer applied to the seedling boxes in order to grow seedlings with rooting vigor equivalent to that of \"field seedlings\" in the easy-to-manage \"water seedlings\" method. Seedlings grown with this method have high rooting power, grow well after planting, and produce higher yields than conventional seedlings, and the method has been widely used from Tohoku to Hokkaido (Figure 8).<\/p>\n\n\n

(2) Local fertilization of fruit and vegetable crops<\/h4>\n\n\n\n

\u3000Even in horticultural crops, where full-layer fertilization has been the mainstay, local application methods have been demonstrated with the advent of coated fertilizers.<\/p>\n\n\n\n

(1) Tomato: Total in-pot fertilization method (Soil Fertilizer Department, Shizuoka Prefectural Agricultural Experiment Station)<\/h5>\n\n\n\n

\u3000When tomato seedlings are potted into No. 4 pots, Superlong 424-140 is added along with medium to grow tomato seedlings, and when the seedlings have grown, they are removed from the pots and transplanted into the main field. (The amount of nitrogen fertilizer applied was reduced from 20 kg to 16 kg\/10 a.) The yield was higher than that of the conventional method. This is a practical fertilization method that outperforms conventional methods in terms of yield (Fig. 9, Tables 8 and 9).<\/p>\n\n\n

\u3000The total in-pot fertilization method frees the farmer from fertilizer application work, allowing him to concentrate on other tasks such as harvesting and picking, and thus enables the farmer to expand the scale of his business. Since fertilizer application is not required in the main field, it is no problem to make ridges long before planting, allowing for the dispersal of field preparation work. In order to popularize this method of fertilization, it is necessary to support the development of inexpensive metering equipment that applies a fixed amount of long fertilizer in pots.<\/p>\n\n\n\n

\u3000This is literally a fertilizer application method in which holes are drilled with a drilling machine in the area where the seedlings are to be planted, and the required amount of fertilizer is dropped into the holes and mixed with the soil before the seedlings are planted. Since the new roots that develop after planting come into direct contact with the fertilizer, long fertilizers containing nitrate-form chisso are used. In addition, this study was also conducted to develop an accessory equipment for transplanters that transplant lettuce seedlings and apply a fixed amount of fertilizer in the planting hole. Reduction of planting labor is a particularly important issue for agricultural corporations with large planted areas of leafy greens, and the development of machinery that simultaneously performs planting and fertilizer application at the time of transplanting seedlings is expected to advance. For vegetables with high planting densities that are generally covered with mulch, the Long will be used in a wider range of applications, including reducing the labor required for fertilizer application.<\/p>\n\n\n\n

\u3000The cultivation method in which the amount of nitrogen fertilizer applied to the planting hole is reduced from 50 kg to 40 kg\/10 a and long fertilizer is applied, and celluloid seedlings are planted, also produces yields equivalent to the conventional fertilizer application method. Simultaneous transplanting using a transplanter with hole fertilizer application enables a reduction in labor time to about 1\/3 of that required for conventional cultivation, thus saving labor as well as reducing fertilizer (Table 11). The use of mechanical transplanters for planting large numbers of leafy vegetable seedlings has advanced, and it is estimated that their use is expanding. If these transplanters can be equipped with an automatic fertilizer dosing machine, the number of planting hole fertilization methods for leafy vegetables will further increase.<\/p>\n\n\n

(3) Barrel-shaped large pot cultivation<\/h4>\n\n\n\n

\u3000This is a cultivation method in which coconut fiber is added in mortar-shaped barrels made of reinforced styrofoam as a substitute for soil and a special fertilizer (based on Hi-Control) for total basal fertilizer that does not require additional fertilizer. There are cases where 850 pots are grown in one greenhouse.<\/p>\n\n\n\n

(4) Future development of root zone control cultivation<\/h4>\n\n\n\n

\u3000There are many examples of controlled root zone cultivation. Although the amount of fertilizer demand used on a single farm may not be large, the number of farmers adopting new cultivation methods is expected to increase due to the remarkable progress in cultivation facilities and equipment. Strawberry cultivation, which used to be done in the ground, is now going to be dominated by upland cultivation due to the aging of farmers, ease of field management, and safety and security requirements.
\u3000Root zone control cultivation of many crops is expected to increase as field management becomes more mechanized. The use of long and high control, including nitrate-form chisso, suitable for this cultivation method is expected to expand.<\/p>\n\n\n\n

\u3000The most labor-intensive tasks in agriculture are planting and harvesting. In rice paddy farming, a riding fertilizer application machine that can plant seedlings and apply fertilizer at the same time has been put to practical use, and in harvesting, the development of unmanned harvesters is now being pursued in place of riding harvesters. In the future, reducing labor at the time of planting leafy greens, which are planted in large numbers, will be an important issue. The development of a granular localized fertilizer application machine for vegetables has already been attempted, and it is expected that more user-friendly machines will be developed (Table 12, Photos 6 and 7).<\/p>\n\n\n

\n

\u3000When agricultural machinery manufacturers develop this equipment, it is necessary to explain the advantages of using long, which contains nitrate-form chisso and is best suited for local application of fertilizer in planting holes and pots, and have them incorporate it into their designs. In the commercialization of \"Okudake,\" a teapack filled with Long, we explained the characteristics of Long and completed the manufacturing process by changing the sliding plate to a brush to prevent damage to the film. We believe that tie-ups with agricultural machinery manufacturers from the initial stages of fertilizer equipment development are important for increasing demand for the Long in the planted hole fertilizer application method.<\/p>\n\n\n\n

\u3000The first and most routinely utilized example is in response to inquiries from extension organizations, government agencies, and the general public. For example, \"What kind of soil is the soil in the 00 region? What are its characteristics? or \"What is the heavy metal content of the general agricultural land? and \"What is the increase or decrease of XX content in paddy soil now compared to the past?\" The aforementioned basic soil fertility conservation survey report, soil map, and basic soil environment survey report are used to answer such questions. For earlier data, we can trace back to the results of the Low Production Land Survey conducted in 1949.<\/p>\n\n\n\n

\u3000Based on the results of the fertilizer reduction test, a fertilizer reduction standard was established and included in the fertilizer application standard. The actual situation of insufficient humus content was also the basis for conducting a continuous organic material application test. In determining the organic material application standards, sludge was determined based on the accumulation of heavy metals such as zinc content in the soil. This was determined by predicting the amount of accumulation based on the amount present in the soil based on the results of fixed-point surveys.<\/p>\n\n\n\n

(4) Soil diagnostic reference values and their use in soil diagnostic programs<\/h4>\n\n\n\n

\u3000In this prefecture, soil diagnostic standard values are set for each crop. The appropriate base saturation is set in three categories based on the average CEC of the soil in the prefecture. The diagnostic standard values are also used in the judgment criteria of soil diagnosis conducted by JA Aichi Keizairen, and the criteria are standardized within the prefecture.<\/p>\n\n\n\n

(3) Utilization for organic material application standards<\/h4>\n\n\n\n

\u3000The standards for the application of organic materials provide standards for the application of organic materials distributed in the prefecture, including livestock manure (Table 1).<\/p>\n\n\n

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

\u3000The application amounts and precautions for application reflect the results of the reference point survey and other continuous organic matter application tests. The following are shown as application effects and precautions.<\/p>\n\n\n\n

In (1) paddy field, organic matter in the soil does not decrease even if organic materials such as compost are not applied for more than 80 years, as shown in Figure 5. Furthermore, the application of compost makes the soil fertile with accumulated organic matter.<\/p>\n\n\n

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

In the field, as shown in Figure 6, if organic materials are not applied, the organic matter in the soil decomposes and fertility declines. Therefore, the application of organic materials is an indispensable technology in the field.<\/p>\n\n\n

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

When the free iron oxide content of the crop soil is less than 1.5% in a paddy monoculture, the maximum amount of bark compost and rice straw compost should be applied is 1000 kg\/10a to prevent fallout. Especially in fields with low iron content, the application of large amounts of organic materials should be avoided.<\/p>\n\n\n\n

The standard soil diagnostic value of humus in field soil is 3-5%. In the case of an open vegetable field on yellow soil, humus content reached 51 TP3T after 10 years of continuous use of 3000 kg\/(10a\/year) of cattle manure and 2000 kg\/(10a\/year) of pig manure.<\/p>\n\n\n\n

\u3000Therefore, application of less than these standard amounts is sufficient to maintain soil fertility. If more than the standard amounts are applied, the discharge of nitrate nitrogen into groundwater and rivers will be extremely high, and the discharge of dinitrogen monoxide, which has a great impact on global warming, will increase, resulting in a great burden on the environment.<\/p>\n\n\n\n

(3) Method of providing data<\/h4>\n\n\n\n

\u3000JA-Aichi Economic Federation is constructing a system to obtain and use various agricultural information from prefectural maps in a joint research project with the National Research Institute and Nagoya University.
\u3000In the near future, the information that can be provided will be enhanced by adding soil maps and soil data to it.
\u3000In the future, it is expected that digital information will be developed so that farm management will be possible on smartphones and tablets.<\/p>\n\n\n\n

(4) Development of physicality diagnosis method<\/h4>\n\n\n\n

\u3000In order to provide detailed guidance for each field, it is important to diagnose the physical properties of the soil before diagnosing the soil chemistry. The first priority should be to determine whether or not conditions are in place for normal root growth, and if so, to improve these conditions. In the diagnosis of poor growth in the field, the cause is often the densification of the subsoil or poor drainage. For quality-oriented crops such as fruit trees and vegetables, it is important to fully understand the movement of moisture and water retention in the soil, but it seems that no such means have been established. Therefore, it is necessary to develop and disseminate a physical property diagnosis method that can be easily utilized in the field in the future.<\/p>\n\n\n\n

6. at the end<\/h3>\n\n\n\n

\u3000In the agricultural field, there is a growing trend toward the development and diffusion of technologies that aim to make farming \"easy\" and \"accessible to everyone\" by making full use of ICT, AI, and other technologies. On the other hand, it is true that we can share the \"joy of production\" by walking through the field one by one, digging holes while listening to the voices and concerns of individual producers, checking soil hardness, drainage, and root distribution, and discussing the growth of crops. In the future, it would be desirable for all those involved in soil fertilization to review the assets of the soil fertilization field to date and discuss bringing them back to life.<\/p>\n\n\n\n
