Penetration of fertilizers based on humic substances through plant cuticles

Original language description

Plant cuticle forms a primary barrier, which must be overcome by a foliar agent (fertilizer, pesticide) to influence a physiology of a plant. Among the foliar agents, humic acids represent the material of the growing importance. They are known for positive effects on the quality and fertility of soil, growth and productivity of plants. Ability of humic acids to penetrate into the leaf can be studied in laboratory using isolated plant cuticles and simple diffusion techniques. Diffusion pair was formed byconnecting agarose hydrogel containing dissolved humic acids and blank agarose hydrogel, with the isolated cuticles placed between the gels. Humic acids diffused through the isolated cuticles into agarose gels from the aqueous solution. Diffusion experiments were quantified by means of ultra-violet spectroscopy
