The structure and dynamics of the resources of plant substance in agrocenoses of sowing camelina

The research purpose was to study the structure and plant matter stocks in the agrocenosis of Camelina sativa (L.) Crantz, cultivated for oilseeds in the Kansk forest-steppe. The soil cover in the study site was represented by the combination of typical clay and illuvial agrochernozems, clay and illuvial podzolized agrochernozems and cryogenic and micellar low-power agrochernozems occupying microincreases. Aboveground plant matter was determined by mowing method, underground to the depth of 40 cm - by monoliths method. As a part of elevated vegetable substance the phytomass of culture and weeds and an elevated mortmass were allocated. Roots, large and small mortmass were distinguished in underground plant matter structure. All fractions were brought to an air-dry state and then reserves were calculated. The study results showed that the maximum camelina phytomass stock was formed in fruit and seed germination phase and amounted to 2.9 t/hectare. At the same time, maximum root reserves were found in the 0-40 cm layer, which made 2...
