Preparation of silica
Until the leaves are formed, flowers and fruits, each plant needs a lot of light and warmth. Preparation of silica due to the content of silicon, as if transmitting light, enhances the intensity of life processes in the plant. This preparation is used in very low concentrations for spraying plants, which promotes the development of leaves, flowers and fruits and their ripening. The effect of the preparation depends on the date of its use. While the cow's preparation is used only during the sowing and planting period or after harvesting or cutting the plants, it does not have a strict term of silica spraying and it can be applied to plants at various stages of development. How does it work in practice? The seeds are sown into the soil, which was sprayed with cow preparation within a specified period. Young plants sprout, which, however, we do not immediately spray with the silica preparation, because it can be harmful to them. This can be seen by spraying freshly transplanted plants with silica too early, which have not yet taken root well, or lettuces with undeveloped heads. Signs of damage are yellowing (chloroza) leaves, premature killing of inflorescence shoots or too loose lettuce heads. Many a gardener has found out, observing this unfavorable phenomenon, that although there is no doubt about the positive effect of the preparation, even in such a small dose, before spraying, the plants must first "come into contact" with the soil, that is, to root well, so that they can take full advantage of the beneficial effects of the silica preparation. This effect is based on improving the light use of the plant and increasing the intensity of growth.
We divide vegetables into root vegetables, leafy and fruity. From this, to which group does the vegetable belong, the date of the first treatment depends. The preparation is used for the first time then, when you can already see the beginnings of the fetuses. So when the carrot root turns orange, when lettuce heads bind, when the first pea pods are visible or when the tomato fruits reach the size of a hazelnut.
The problem is with fruit plants, which usually have buds at the same time, flowers and fruit, therefore it is difficult to choose the date of spraying. Practice has found a good solution here, namely: use of the silica preparation in the morning or morning hours. The earlier in the morning you start spraying, the more effective the preparation is. In the morning the flowers are still closed or covered with dew, which protects them against possible damage.
Studies have also shown, that silicon has a specific effect on the metabolic processes typical of the various phases of plant development. Therefore, it is used for root vegetables in the afternoon. The organic compounds produced in the leaves during the day are transported to these organs in the evening and at night, where they are necessary for their construction or will be set aside. The use of silicon accelerates this process. If the ripening blackberries are sprayed with a silica preparation in the afternoon, their shoots will be more resistant to fungal diseases and will stop growing sooner, which in turn will increase their frost resistance. This was also true for fruit trees. Spraying trees in the afternoon during fruit ripening and after harvest, you can improve their quality. The use of silica preparation after harvesting the fruit increases the resistance of trees in the next growing year.
Engqvist obtained interesting results (1963) and Klett (1968) by studying the development of shaded plants. Shaded plants, but sprayed with a silica formulation, gave the same yields, like plants growing in full light and not sprayed. This proves the strong influence of this preparation on the plant.
Abele (1973) stated higher Fr. 20% sugar content in sugar beets sprayed with this preparation. The results of the new experiments confirmed the observations from the 1930s, according to which the preparation increases the resistance of plants to pests, stimulates plant growth, influences better fruit ripening and a higher content of volatile oils in medicinal plants, improves the taste and durability of the crop.
