\u3000The various forms found in the above-ground part of the plant are only possible through the maintenance of the individual organism, and its survival would not be possible without the presence of roots. Roots receive photosynthetic products from the above-ground parts, and they also transfer water and nutrients to the above-ground parts. The flow of water is shown in Figure 1. Roots absorb water attracted to the soil (called water potential, the value of which is always negative) and raise the water from the stem to the leaves, where the water potential is lower. Rather than being lifted, the water is pulled up by the transpiration force generated by the water potential of the leaves. The water evaporates from the leaf and cools the leaf surface as heat of vaporization. At this time, the various nutrients dissolved in water in the form of ions are distributed to the various parts of the plant. The water flow in the plant differs greatly from day to night.<\/p>\n\n\n

\u3000In the previous issue, I reviewed the history of how, in the days before the advent of chemical fertilizers, farmers overcame the difficult problem of supplying nutrients to farmland by devising a material called compost. I also mentioned the difference in the way of farming between the fields in Europe and the rice paddies in Japan, which led to a difference in the way of thinking about compost. Even after the advent of chemical fertilizers, compost is expected to have various effects. However, these various effects do not occur in all soil types without exception. Let us consider what are the conditions of soil that cause differences in the manifestation of these effects.<\/p>\n\n\n\n

\u3000However, the effect of (2) as a trace element fertilizer cannot be expected in paddy fields. This is because trace elements are dissolved in irrigation water in rice paddies, and the amount of trace elements supplied by irrigation water, which is taken up in large quantities during rice cultivation, is large. Even if the compost contains trace elements, the limited amount of trace elements supplied by the compost will not be equal to the natural supply from the irrigation water.<\/p>\n\n\n\n

\u3000It is not yet well known how effective the plant hormones (4) can actually be in fields and rice paddies with a history of cultivation. However, it is likely to be effective when the surface soil containing organic matter is completely removed and the subsoil containing little organic matter is used as the cropping soil, as is the case in cultivated land.<\/p>\n\n\n\n

(2) Effect as stable organic matter<\/h4>\n\n\n\n

\u3000The second expected effect is as stable organic matter. Stable organic matter is organic matter that remains in the soil after being decomposed to some extent by animals and microorganisms, and is relatively difficult to decompose. This becomes the substance known as soil organic matter (humus), which gives the soil its black color.<\/p>\n\n\n\n

\u3000The effect of compost application on soil organisms is more likely to be cumulative than a one-year effect. However, even in this case, the direct effect of the diversification and increase in the number of organisms on crop growth may vary depending on other soil conditions.<\/p>\n\n\n\n

2. the less organic matter in the soil, the more effective compost is.<\/h3>\n\n\n\n

\u3000When we give compost to the soil nowadays, are we just giving it to the soil without any particular reason, just because it is for \"soil building\"? We need to think carefully about why we are giving compost to the soil and what effect we expect it to have. Depending on soil conditions, compost may or may not have the desired effect. As shown in Table 1, the criterion is whether the soil has more or less organic matter.<\/p>\n\n\n\n

\u3000The amount of organic matter in the soil can only be determined by strictly analyzing it. To determine the amount of organic matter without analyzing the soil, look at the color of the soil. If the color of the soil is black to dark brown with a black tint, you can judge that there is a lot of organic matter in the soil.<\/p>\n\n\n\n

\u3000Soils with low organic matter (light black color) can expect diverse effects from compost feeding. For soils with high organic matter (dark black color), we should expect mainly nutrient effects as a slow-release three-element fertilizer.<\/p>\n\n\n\n
