The remarkable influence of organic inputs, such as manure and compost, on dN values of growing plants suggests the possible use of N natural abundance as a tracer of N. Thus, using N natural abundance might be possible to estimate compost-N recovery as an alternative method to the use of N-enriched materials. The objective of this study was to verify the feasibility of using dN value to esti...
In the title compound, C36H42O8, the dioxolane ring adopts a twist conformation; the two adjacent C atoms deviate alternately from the mean plane of other atoms by -0.287 (5) and 0.174 (5) Å. The cyclo-hexane, cyclo-hexa-diene and central cyclo-octane rings show chair, half-chair and boat-chair forms, respectively. As a result of the strained ring system, the tetra-subsituted olefin in the cycl...
