The influence of humic acids based products on the productivity of late-ripening white cabbage hybrid "Aggressor" has been studied. It is established that spraying of plants with the solution of Reasil Micro Hydro Mix increased the yield of cabbage heads by 15.8 t/ha (21% higher than control). Treatment with the solution of Humate K-Na with microelements increased the productivity of cabbage by 10.25 t/ha (14% higher than control). Maximum yield of white cabbage within the experiment (100.81 t/ha) was obtained with double application of Reasil Forte Amino Magnesium on the background of Reasil micro Hydro Mix. All studied products based on humic acids positively influenced on accumulation of dry matter, vitamin C, the amount of sugars and the content of nutrients. At the same time, they also contributed to an increased removal of nitrogen, phosphorus and potassium from the soil. The products did not affect the content of nitrate nitrogen in the products.
