Copper sulfate is known as blue vitriol. It is one of the most common compounds of copper and is the most industrially produced copper salt. Suitable against fungi on plants, for the impregnation of wood against fungi.
What is blue vitriol:
Blue vitriol, i.e. copper sulfate, contains 25% copper. For example, 4 g of vitriol contains 1 g of copper. Copper acts as a biocide, inhibiting the growth of undesirable organisms and works very well specifically as an algicide, i.e., against algae. The difference between vitriol and chlorine is that chlorine has a significant problem with already growing algae. A sufficiently effective and life-safe concentration of copper is 1 to 2 mg/l, which corresponds to 4 to 8 mg/l of blue vitriol, i.e., 4 to 8 g/m³.
Use in agriculture:
Blue vitriol is intended for supplemental nutrition of agricultural crops with higher demands for this element (wheat, barley, oats, clover, and others). Copper positively affects the stability of chlorophyll and prolongs the period of active photosynthesis. In the case of copper deficiency, nitrogen utilization from fertilizers is significantly reduced. A characteristic symptom of copper deficiency is white spots and white tips of leaves, which particularly affect legumes. Copper sulfate is suitable for foliar application, which should not be carried out in direct sunlight. Copper sulfate is also used to suppress moss, lichens, and diseases in plants.
Dosing in agriculture:
Fertilization (by watering and spraying) 0.5 g per 1 l of water per 1 m². Pre-sowing soaking of seeds (when sowing in soils with low Cu content) solution 0.02 - 0.05%, i.e., 0.2 - 0.5 g of fertilizer per 1 liter of water. Suppression of lichens, moss, and fungal diseases (by watering and spraying) 10 - 20 g / 1 l of water (it cannot be precisely determined how much area this dose will cover, as it depends on the size of the leaf area or crop)
