FIELD: food industry.
SUBSTANCE: method for pre-planting treatment of potato tubers is implemented with the help of a suspension of nano-particles of iron oxy hydroxide (IOH), ultrasonically treated. IOH is isolated with water treatment wastes at artesian water deferrisation stations. IOH is used in a gel condition. The gel contains 10-12% of IOH. The IOH gel is used in the form of a 0.01-0.001% suspension, inter alia - mixed with a protectant. IOH is also used in a modified condition. The modifier is represented by PVA in an amount of 0.5-1.0% in conversion to IOH dry matter. Modified IOH can be used as mixed with a protectant.
EFFECT: invention usage will allow to ensure potato yield increase and quality enhancement.
