The effect of new biologically pure organic fertilizers, Dia Guma and Gumi Turf, on the yield and quality of grape seedlings on nutrient-poor soils has been studied. The positive effect of silicon - organic fertilizer Dia Gum in combination with the growth stimulator Zircon on the survival rate of shanks, the formation of the aboveground part and the root system of plants is shown (the survival rate of shanks in relation to the control (pure water) increases almost 2 times from 36 to 70%, the diameter of growth - from 4.3 to 7 mm, total growth - from 32 to 54 cm, the volume of the root system - from 15 to 25 cm3). The use of peat - sapropel concentrate Gumi Peat in combination with the growth stimulator Zircon, according to the results of the yield and quality of the planting material, is close to the use of Dia Guma + Zircon. These fertilizers allow to a greater extent to biologize the process of growing planting material in the nursery.
