E:mail:vniilsekretar@mail.ru, kuzmenko.nataliya2010@mail.ru On the basis of a long-term stationary experiment, it has been established that the saturation of crop rotation with fertiliz- ers at the annual application of 230 and 280 kg a.i./ha maintains the fertility of soddy-podzolic soil and the productivity of flax crop rotation at a level of 33.7-35.7 ct g.u./ha.
