Abstract
The results of long-term studies on the effect of methods of basic soil cultivation and organic-mineral fertilizers on the agrophysical, agrochemical indicators of sod-podzolic soils and their biological activity on productivity and qualitative indices of fibre flax in the conditions of the Precarpathian region are presented. The use of organic fertilizers, with the application of ploughing at 14-16 cm and disking of 8-10 cm with deep loosening of 35-40 cm, contributed to an increase in moisture reserves in the soil and improved the water and physical properties of the arable and subsoil layers of the soil, which positively influenced the development of plants and the formation of yield of fibre flax. In particular, on fertilized variants, moisture reserves during the sprouting, at a depth of 0-20 cm, varied within the range of 30.6-39.5 mm, and at a depth of 20-40 cm, respectively, 90.8-94.2 mm. The same pattern was observed to harvest time of fibre flax. The investigated methods of basic soil cultivation and fertilization significantly influenced the growth and development of fibre flax plants and ensured an increase in yield and improved quality of flax fibre.
