Parameters of compensation of soil moisture deficiency when planting Pinus sylvestris L. seedlings with a closed root system on the burns of ribbon hogs

The research goal was to determine the soil moisture deficiency and the normalizing parameters of moisture compensation for planting seedlings of the pínus sylvéstris culture with  a closed root system  on burning in a dry-steppe climatic zone. The research was carried  out in the southern part of the Barnaul ribbon  of ribbon  pine forests of the Altai  region. Common, productive and  hard-to-reach moisture reserves  in  the  soil  were  determined. The  observations were  carried  out  at  different times and   on  different  elements  of  the  mesorelief. Studies  have   shown   that   the  moisture  parameters of a twenty-centimeter soil layer over the entire  measurement period reach critically small values  on all the mesorelief  elements considered. The maximum natural moisture content was observed in the lowland during July observations. The lowest natural moisture reserve was recorded in September on the southern slope. The maximum moisture deficit was about  16 mm  for a twenty-centimeter layer of the studied soil and  50 mm  for a meter  layer  and  was  determined by the observation period,  as well  as the exposure of the mesorelief. With  artificial reforestation of Pínus  sylvéstris L. in the area of research  by seedlings with  a closed  root system, the  moisture compensation parameters are at  least  70-150  t/ha  for a soil layer of 0-0.2 m and  170-490 t/ha for a layer of 0-1.0 m. The calculated parameters of water  deficiency and moisture compensation in soil layers can be useful  when planning reforestation works.
