Fertilizer based on humic acids with microelements

The use of complex liquid fertilizers, including those with microelements and biologically active additives, is a modern agrochemical technique and an important factor in increasing yields, improving the quality and microelement composition of agricultural products. The authors have developed a technology of liquid humate-containing fertilizer “Tesoro” obtaining by introducing nitrogen, potassium and microelements compounds of important biological significance for plants into humic preparation. The study of the chemical composition of the fertilizer showed the presence in its composition, in addition to nutrients, biologically active compounds, including humic substances, low-molecular organic acids, phenolcarboxylic acids with growth-stimulating properties, and a wide range of macro- and microelements, many of which are necessary for growth, development and increased productivity of plants. Agrochemical tests of new “Tesoro” fertilizer showed that its use in tomato, cucumber and green crops cultivation in open and protected soil contributed to morphometric parameters of plants improvement, increase in yield, the growth of fruit marketability and the reduction of nitrate accumulation in vegetable products compared to control and reference – Gumirost liquid fertilizer.
