Soil and Irrigation.
Оглавление—The soil best suited to the currant grape is a calcareous marl, which must be of good depth, loose, and easily worked. Such marls are also prized for their great power of retaining moisture. But vineyards are planted in Cephalonia, Zante and Ithaca in the most different soils and situations. They are found in gray marls, in red clay, on the plains and among the hills, in fact, in the most widely different situations. The soil of Zante contains a small percentage of sulphate of lime or gypsum, which is by many considered indispensable for the successful and profitable culture of the currant vine. The currant vine thrives especially in low and rich land which can be irrigated, and irrigation is quite essential to the perfect development of the grapes. Many vineyards, however, are not irrigated, the irrigation, of course, only being practicable on the plains. This irrigation is practiced from October to the end of December, often while the natural rainfall supplies the artificial watering. The lands are generally small freeholdings, owned by the peasants. The most valuable currant vineyards are situated on the rich and level valley lands.
