In field experiments on turfen-podsolic mead - loamy soil the influence of the optimal and high level PHKCI on the fiber content in the trust, its quality indicators and productivity is investigated. It is established that on the soil with an optimum level of acidity for flax, the cultivation of flax of grade Blakit provides the trust productivity of 5.04 – 5.23 t/ha with number 1.75, the profit is 601.0–636.7 US dollars per hectare of crop and the profitability of flax cultivation is 93.5 – 97.0%. Processing trusts with such a quality and realizing export flax fiber enables gaining the profit of 285 – 353 US dollars per hectare of crop and the profitability of 15.4 – 18.5%. When cultivating flax on the soil with PHKCI 6.3 – 6.5 the application of boric and zinc fertilizers raises the trust productivity from 3.54 to 4.80 t/ha, however the number of trust does not exceed 0.75 units. Realization of such trusts can give profit of 26–30 US dollars per hectare and the profitability of its manufacture of 5.4 – 6.2%. Processing trusts with number 0.75 at the productivity of 4.8 t/ha can provide the profitability of 11.1 – 11.2% under the condition of realization of export flax fiber. When flax fiber is realized under internal prices, processing trusts becomes unprofitable even when it is cultivated on soils with favorable agrochemical parameters and at the productivity of more than 5 t/ha of trust with number 1.75
