Reference has been made to the extensive use of straw in the cultural methods of the Japanese. This is notably the case in their truck garden work, and two phases of this are shown in Fig. 245. In the lower section of the illustration the garden has been ridged and furrowed for transplanting, the sets have been laid and the roots covered with a little soil; then, in the middle section, showing the next step in the method, a layer of straw has been pressed firmly above the roots, and in the final step this would be covered with earth. Adopting this method the straw is so placed that (1) it acts as an effective mulch without in any way interfering with the capillary rise of water to the roots of the sets; (2) it gives deep, thorough aeration of the soil, at the same time allowing rains to penetrate quickly, drawing the air after it; (3) the ash ingredients carried in the straw are leached directly to the roots where they are needed; (4) and finally the straw and soil constitute a compost where the rapid decay liberates plant food gradually and in the place where it will be most readily available. The upper section of the illustration shows rows of eggplants very heavily mulched with coarse straw, the quantity being sufficient to act as a most effective mulch, to largely prevent the development of weeds and to serve during the rainy season as a very material fertilizer. In growing such dry land crops as barley, beans, buckwheat or dry land rice the soil of the field is at first fitted by plowing or spading, then furrowed deeply where the rows are to be planted. Into these furrows fertilizer is placed and covered with a layer of earth upon which the seed is planted. When the crop is up, if a second fertilization is desired, a furrow may be made alongside each row, into which the fertilizer is sowed and then covered. When the crop is so far matured that a second may be planted, a new furrow is made, either midway between two others or adjacent to one of them, fertilizer applied and covered with a layer of soil and the seed planted. In this way the least time possible is lost during the growing season, all of the soil of the field doing duty in crop production.
