Water-soluble fertilizer consists of microelement calcium 950 g / kg and specially prepared plant extract. Mechanism of action: Calcium affects the metabolism of carbohydrates and proteins in plants. The need for calcium is manifested in the early stages of growth, it is essential for plant formation. Lack of calcium hinders the processing and assimilation of reserve foods (starch, proteins) used by seedlings, young leaves and growing twigs. This can cause the young growing parts of the plant to wither and the whole plant to die. Facilitates the transport of carbohydrates to the plants; Strengthens cell walls and connects them to each other; It is needed to promote the development of the root system; Essential for leaf development; Increases plant resistance to certain diseases; Stimulates the activity of bacteria on the roots, which fix nitrogen from the air. Calcium also affects soil fertility: it stimulates the action of beneficial microorganisms that synthesize nitrogen in compost piles; Reduces soil acidity and accelerates the processes of ammonification and sulfur oxidation; Promotes the production of humus; Accelerates the decomposition of organic matter in the soil; Reduces the toxicity of iron, manganese and aluminum by neutralizing their excess amounts. Calcium improves the mechanical composition of the soil and, consequently, improves the permeability of air and water in it; Promotes the formation of soil structure (aggregates). Advantages: • Development of the root system; • Strengthen immunity; • High bioactive efficiency; • High content of micronutrients; Consumption rate kg / ha: foliar feeding -1,5; Root feeding -2.0;
