Copper sulfate is known as blue vitriol. It is one of the most common compounds of copper and is the most widely produced copper salt industrially. Suitable against mold on plants, for wood impregnation against fungi.
What is blue vitriol:
Blue vitriol, or copper sulfate, contains 25% copper. For example, 4 g of vitriol contains 1 g of copper. Copper acts as a biocide, suppressing the growth of undesirable organisms and works very well specifically as an algicide, that is, against algae. The difference between vitriol and chlorine is that chlorine has a big problem with already growing algae. The 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 the supplementary nutrition of agricultural crops with higher requirements for the specified element (wheat, barley, oats, clover, and others). Copper positively affects the stability of chlorophyll and extends the period of active photosynthesis. When there is a copper deficiency, the utilization of nitrogen from fertilizers decreases significantly. A characteristic symptom of copper deficiency is white spots and white tips on leaves, which especially affects legumes. Copper sulfate is suitable for foliar application, which is not recommended to be done in direct sunlight. Copper sulfate is also used to suppress moss, lichens, and diseases in plants.
Dosing in agriculture:
Fertilization (watering and spraying) 0.5 g per 1 l of water per 1 m². Pre-sowing soaking of seeds (when planting in soils with low Cu content) a solution of 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 (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 stand)
