THE EFFECT OF COMPLEX FERTILIZERS WITH THE ADDITION OF IRON-CONTAINING COMPOUNDS ON THE INTAKE OF IRON IN THE SOIL AND OIL FLAX PLANTS

Abstract

The article presents data on the effect of new forms of complex fertilizers with the addition of iron-containing compounds in the form of sulfates or chelates) on the entry of iron into the soil (arable horizon), seed yield, oil content, iron intake in oil flax plant in the “herringbone” and flowering phase (stem, inflorescences and roots), plant affection by various diseases when cultivated on sod-podzolic loose sandy soils. It was found that the inclusion of iron-containing compounds in doses (0,07-0,10 % by weight of fertilizerand, mainly iron-containing compounds in complex with plant growth regulators (Epin, Hydrohumate) has a positive effect on seed yield, oil content with a one-time reduction in the incidence of plant growth by various diseases.
