Abstract: 
Physico-chemical properties of specially modified forms of natural biopolymers – carboxymethyl cellulose and xanthan gum – were studied. The effectiveness and ability to film formation of water soluble polymeric compositions of these biopolymers, their influence on the growth and productivity of agricultural crops were examined. The effect of the biopolymers, mineral fertilizers and micronutrients content in the solution on its viscosity, as well as the dependence of the formed films thickness on the content of modified biopolymers and fertilizers were investigated. It was established that using natural film-forming compositions the consumption of fertilizers and micronutrients per hectare of crops reduces significantly (by 10-100 times), the yield of plants increases by 15–80 %. The compositions are characterized by high sanitary, hygienic and ecological indicators.
