What reading level is Effect of Chemical Treatment of Pea Seed On Nodulation By Rhizobium Leguminosaru book?
To quickly assess the difficulty of the text, read a short excerpt:
In the soil with optimum moisture the chemicals practically prevented nodulation, while in the soil with a suboptimum water con- tent nodulation was not reduced so severely.
Field Studies, 1935 and 1936 In the springs of 1935 and 1936 attempts were made to secure experimental data on the effect of chemical seed treatments on nodula- tion under field conditions, but the various soils in which the peas were planted contained the nodule-forming bacteria and nodulation conse- quently occurred on al...l plots whether or not the seed was inoculated. This is, however, a very significant point, for no peas had been grown for from six to ten years on the soil used in these field studies. Thus where peas are grown in a three- to five-year rotation on fertile soils that are not too acid, it should not be necessary to inoculate the seed of later crops if earlier crops have been well nodulated, for nodulation will result from the bacteria already present in the soil.
These field studies showed conclusively that the treatment of pea seed with Semesan, cuprous oxid, or zinc oxid does not influence nodulation if the nodule-producing bacteria are already present in the soil.
