Introduction<\/h3>\n\n\n\n

\u3000Fill-fill type root zone control cultivation is a method of cultivating fruit trees in a limited amount of fill, which is separated from the ground by a root barrier sheet and covered with medium. The method allows for early maturing and high-yielding fruit trees through careful management of watering according to the growth of the tree. The Tochigi Prefectural Agricultural Experiment Station developed this technique and established it for pears.<\/p>\n\n\n\n

\u3000The medium is a mixture of red ball soil and bark compost at a ratio of 2:1 by volume, and the volume of medium per tree is 150 liters. A root-impermeable sheet called a \"root barrier sheet\" is laid down, the medium is piled on top, and the saplings are planted in a trapezoidal shape. The root zone is restricted so that the trees are compact. The planting interval is 2.0 m between trees and 2.5 to 3.0 m between rows, and the number of trees planted per 10 a is 200 at 2.5 m between rows and 185 at 2.7 m between rows. The main branches are branched at a height of 90 cm above the ground to form a two-branch, one-letter tree, and 16 resultant branches are induced at a 45\u00b0 angle upward from the two-branch, one-letter skeleton to form a Y-shaped tree.<\/p>\n\n\n\n

\u3000The fruit set was set at 45 grains per bunch, with 10 bunches per tree in the second year of planting in 2008 because the trees were still small, and 22 bunches per tree from 2028 to 2020, when the trees were fully formed. The general cultivation management was based on the short-shoot cultivation of Cheinmuscat, and the management specific to the heaped root-zone controlled cultivation was based on the heaped root-zone controlled cultivation of pears.<\/p>\n\n\n\n

4. points to keep in mind for technology dissemination<\/h3>\n\n\n\n

\u3000This study was conducted on young vines up to the fifth year of age (the fourth year or older is considered mature in root-zone controlled cultivation), and the effects of consecutive annual applications over a long period of time were not examined. In addition, a simultaneous one-shot application system of basal and supplementary fertilizer was considered for grapes, but it should be noted that the effects of substituting supplementary fertilizer need to be confirmed for the following year's growth, and there are points that have not been fully examined at this point in time.<\/p>\n\n\n\n

\u3000Starting with this month's issue, I will be writing a series of articles titled \"Soil Matters\" for a while. I would like to provide soil-related information in a reading style that is somewhat different from the technical information in the other articles in this magazine. First of all, I would like to discuss what kind of soil is \"good soil,\" which is often talked about by people in the agricultural industry.<\/p>\n\n\n\n

1. experienced chefs call it \"good soil\" just by looking at it...<\/h3>\n\n\n\n

\u3000About 10 years ago in spring, I visited a farm at the foot of Mt. Yotei in Niseko, Hokkaido, with a veteran chef from a famous hotel in Sapporo. They were planting potatoes. A TV reporter asked us what we thought of the field. The veteran chef immediately replied, \"The potatoes from this field must be delicious. You can tell by the dark, soft soil. The smell of the soil, which is so strong that it makes your mouth water, guarantees that you will get potatoes that will turn into a powder when you boil them. He said. I was amazed at how easily he could say, \"You will get delicious potatoes\" just by looking at the soil.<\/p>\n\n\n\n

\u3000I was happy that the chef considered the soil important enough to determine the taste of the potatoes. However, I cannot for the life of me believe that \"black, soft, good-looking soil\" determines the taste and yield of potatoes. If it were determined by appearance, we wouldn't have to bother with labor-intensive cross-sectional soil surveys and soil diagnostics.<\/p>\n\n\n\n

2. Is soil with a lot of compost or soil with many earthworms \"good soil\"?<\/h3>\n\n\n\n

\u3000Whenever I ask farmers what kind of soil is \"good soil,\" a phrase is bound to come up. They say things like, \"Good soil is soil that has been given plenty of compost,\" or \"You can tell if it is good soil by the number of earthworms it has.<\/p>\n\n\n\n

\u3000If a \"good soil\" can be produced by giving plenty of compost, then there is no need for livestock farmers to produce an excess of compost. Even livestock farmers may have farmland, and if they give as much as they can, they will have \"good soil. The question is, how much is \"plenty\" in the phrase \"give plenty of manure\"? The same is true for \"whether there are many earthworms or not. Even if the soil is good if there are many earthworms, how much is \"plenty\"? Without a clear answer, it is impossible to judge whether the soil is good or bad.<\/p>\n\n\n\n

There is nothing inherently good or bad about soil.<\/h3>\n\n\n\n

\u3000He believed that soil is formed by the interaction of various factors, such as the type of rock from which it is made, the climate, flora, fauna, and topography of the site, and that the soil changes over time. Given certain environmental conditions, the same soil will be formed if the raw materials are the same. However, even if the raw materials are the same, the soil produced will be different if the environmental conditions are different. This is because the action of living organisms, which play an important role in soil formation, differs greatly depending on the environment. Dochkachev realized that the environment creates soil.<\/p>\n\n\n\n

\u3000According to Dochtayev's view, we cannot make a value judgment about the soil produced in a given environment as good or bad. This is because the soil produced in a given environment is the only soil that can be produced in that environment.<\/p>\n\n\n\n

\u3000On the other hand, we who are involved in agriculture judge \"good soil\" or \"bad soil\" based on the implicit premise that crops are to be cultivated and on the criterion of whether or not crops can be cultivated without inhibiting their growth in response to that premise. If the criteria are different, the soil may be \"good soil\" for agriculture, but \"bad soil\" for the foundation of a large condominium building. Soil itself is not good or bad. It is merely a value judgment made by people.<\/p>\n\n\n\n

\u3000What kind of soil, then, is soil that does not inhibit the growth of crops, that is, soil that is good for crop production?<\/p>\n\n\n\n

\u3000However, since the above description does not provide specific numerical information to serve as indicators, it is not possible to determine whether each of the conditions is satisfied or not. Table 1 summarizes the four conditions for good soil for crop production, including the specific indicators.
\u3000We plan to explain each of these conditions and indicators in the next and subsequent issues. We hope you will look forward to it.<\/p>\n\n\n

5. concept of biological properties of soil<\/h3>\n\n\n\n

\u3000By the way, when I present the above four conditions, I am often asked why they do not include conditions on the biological properties of the soil (from microbes to animals). Why is it that these four conditions do not include the biological properties of the soil (from microorganisms to animals)? It is not easy to fully explain why in the limited space of a paper. However, we can at least point out the following<\/p>\n\n\n\n

\u3000All of the above four conditions for good soil have a significant impact on the life of organisms in the soil. However, we do not believe that the fulfillment of these four conditions has a negative impact on the life of organisms in the soil. For this reason, we have not added the biological condition of the soil to the conditions for good soil.<\/p>\n\n\n\n
