\u3000Negative factors for endurance in terms of nitrogen nutrition in the leaf blade can be considered as follows. A decrease in nitrogen concentration in the lower leaves (increased senescence pressure in the leaf blade) will require nitrogen from the rice plant, in which case translocation from the lower leaves to the upper leaves will be enhanced. If the wilting of the lower leaves is caused by nitrogen translocation to the upper leaves due to nitrogen deficiency, late wilting occurs, resulting in lower yield and quality. This tendency is more pronounced in fields with low soil fertility and in high temperature years.<\/p>\n\n\n\n

\u3000On the other hand, in rice paddies with high soil fertility, the nitrogen supply is derived from soil fertility, and the concern about a decrease in nitrogen concentration in the lower leaves is considered to be low (low senescence pressure). However, in rice paddies with poor early growth in recent years, it is assumed that a decrease in nitrogen concentration in the lower leaves occurs early after the ear setting stage due to insufficient root mass.<\/p>\n\n\n\n

0Information-linked soil preparation concept
\u3000Based on information from soil analysis and questionnaires (map information), we implement silicic acid materials and rice straw rotting systems for each field, select and concentrate soil preparation sites between and within fields based on sensing image data, and optimize the selection of silicic acid materials and spraying methods using an information system. We will reduce variation in soil fertility, reduce reduction of reduction, and promote early growth and suppress late wilting.<\/p>\n\n\n\n

Fertilizer \"run-out\" evaluation, inter-field and intra-field soil fertility evaluation by 0-sensing
\u3000Optimizing the use of additional nitrogen by constructing a system for determining fertilizer use based on information such as image diagnosis using drone sensing, growth speed after transplanting, and weather conditions (temperature and hours of sunlight); understanding the variation among and within fields; and responding to variable fertilizer application for soil preparation by understanding the reduction of We are also working to reduce variation among and within fields.<\/p>\n\n\n\n

\u3000Table 1 shows the actual information processing using the information-linked fertilizer application system. (1) Secondary information is created from the primary information, (2) the nitrogen amount of side-row fertilizer (equivalent to base fertilizer) is determined from the primary information (soil fertility) and secondary information (dry soil effect), and (3) the amount of nitrogen applied to the seedling box (equivalent to additional fertilizer) is determined from the primary information (variety, soil fertility, weather, yield, etc.).<\/p>\n\n\n

\u3000In recent years, there have been many cases of poor early growth and delayed growth adjustment (drying out), resulting in insufficient root mass due to inability to dry out the seedlings. To get a head start, it is an important strategy to secure strong stems at an early stage by applying side-row fertilizer and leaving the seedlings in the box (drip effect) to allow time for subsequent growth adjustment.<\/p>\n\n\n\n

\u3000It has been a year since I began writing this series of articles in last May's issue. Over the past nine articles, we have discussed four conditions that must be met for soil to be good for crops. These four conditions and specific target values were described in the first article. From Part 2 to Part 9, each of these conditions and their target values were explained. This issue is a summary of these articles. I would like to review the relationship between the concept of good soil and soil cultivation.<\/p>\n\n\n\n

1. what is soil preparation in the first place?<\/h3>\n\n\n\n

\u3000When farmers, as well as readers of this magazine, and others involved in agriculture discuss crop production and talk about soil, the word \"soil preparation\" always comes up. The final response is something like, \"Soil preparation means the application of organic matter such as compost. The conclusion is that no matter what kind of soil or what kind of crops are grown, the first step in \"soil preparation\" is to apply compost, and if that \"soil preparation\" is carried out, it will lead unconditionally to good results.<\/p>\n\n\n\n

\u3000I have an indescribable sense of discomfort with this fixed concept of \"soil cultivation. If it were that simple, I would think that soil with poor crop production would soon disappear from the world. In short, it is only a matter of applying compost.<\/p>\n\n\n\n

\u3000I consider \"soil building\" to be a practical activity to improve the soil of a target field to a soil that is good for crop production. In order to do so, it is necessary to clarify what factors in the soil of the field are inhibiting the growth of crops and to what extent. In other words, it is necessary to clarify which of the \"four conditions for good soil\" described in this series of articles is the greatest inhibitory factor to the growth of crops. Then, the practice of \"soil cultivation\" is the procedure of implementing measures to improve the conditions that have become the growth-inhibiting factors.<\/p>\n\n\n\n

2. does good soil guarantee a high yield?<\/h3>\n\n\n\n

\u3000In reality, however, there is more at stake. Crop growth and yield are not determined solely by whether the soil on the farm is good for crop production.<\/p>\n\n\n\n

\u3000Suppose there is a potato field with the best soil in Japan that satisfies all the \"four conditions for good soil\" through diligent improvement. However, no matter how good the soil is, if the temperature does not rise in summer, for example, the productivity (yield) of the potato field will be drastically reduced due to cold damage. Even if the weather is good, if the fertilizer is applied incorrectly, the potatoes will not produce well. Experienced farmers will be able to produce much higher yields than I, an amateur, can.<\/p>\n\n\n\n

3. soil is one of the factors that determine the crop productivity of farmland<\/h3>\n\n\n\n

\u3000In order for soil to have high crop productivity, it must satisfy all of the \"four conditions for good soil,\" as described in this series of articles. However, it cannot be said that farmland with \"good soil\" that satisfies these four conditions will always produce a high crop yield. This is because \"good soil\" is only one of many factors that determine the productivity of farmland, as shown in Figure 1.<\/p>\n\n\n\n

\u3000The more we value the soil, the more we feel that the soil always determines crop production. As a result, it is often said that \"soil cultivation\" is the most important factor in \"improving crop productivity. Of course, there are many such cases. However, if we assume that soil is the only factor that determines crop production on farmland, we will lose sight of the real impediments to crop production. We must not forget that many factors are interrelated in determining the crop productivity of farmland.<\/p>\n\n\n\n

\u3000The important thing is to be able to consider from a broad perspective what factors are responsible for the poor growth of crops grown on the farm. It would be a pity for the soil to blame the soil for all the causes of various phenomena, such as poor growth of crops. That is an overestimation of the soil. Before we assume that the soil is the cause, it is important to consider the factors that contribute to poor growth, and to accurately gather the factors that hinder growth.<\/p>\n\n\n\n

4. the story of \"the man who planted the tree\" - any soil can always be made better.<\/h3>\n\n\n\n

\u3000I will never forget the words of my former teacher when I was a student: \"Any soil can be made better. This is because I believe that even soil with many shortcomings will one day improve if we find out which of the \"four conditions for good soil\" are the factors that inhibit the growth of crops in that soil, and then do our best to improve those factors.<\/p>\n\n\n\n

\u3000Selflessly and without asking for anything in return, day in and day out, he drilled holes in the barren, marble-covered soil and planted acorns in them. This act transformed the barren land into a land fit for people to lead healthy lives, both physically and mentally. I believe that with a sustained selfless practice like Bouffier's, any harsh, poor soil can be transformed into soil that can produce crops and in which people can live richly in mind and body.<\/p>\n\n\n\n

\u3000What is necessary is to clarify what factors of the soil need to be improved and how, and then to continue with the improvement measures. We hope that you will utilize the \"Four Conditions for Good Soil\" to find these factors. To change bad soil into good soil for crops requires work like bouffier. Simply applying compost may miss the point.<\/p>\n\n\n\n
