  • Carbon-to-nitrogen ratios are an indicator for nitrogen limitation of plants and other organisms and can identify whether molecules found in the sediment under study come from land-based or algal plants. (wikipedia.org)
  • Crop phenology and allocation has separate functions for simulations with and without nitrogen limitation. (lu.se)
  • Vascular plants from terrestrial sources tend to have C/N ratios greater than 20. (wikipedia.org)
  • The lack of cellulose, which has a chemical formula of (C6H10O5)n, and greater amount of proteins in algae versus vascular plants causes this significant difference in the C/N ratio. (wikipedia.org)
  • Carbon and nitrogen are two essential elements for the growth and development of plants and micro-organisms in the soil. (thegrower.es)
  • Hence the need for fertigation systems that constantly supply nitrogen to the plants in substrate production systems. (thegrower.es)
  • A carbon fixation pathway that evolved in some plants as an adaptation to arid conditions. (eol.org)
  • Persons exposed only to nitrogen oxide gases do not pose substantial secondary contamination risks. (cdc.gov)
  • In the analysis of sediments, C/N ratios are a proxy for paleoclimate research, having different uses whether the sediment cores are terrestrial-based or marine-based. (wikipedia.org)
  • The depth of sediment exceeds 1m and would be a suitable study site to carry out paleolimnology experiments with C:N. Unlike in marine sediments, diagenesis does not pose a large threat to the integrity of the C/N ratio in lacustrine sediments. (wikipedia.org)
  • A 2021 study had assigned an age of about 22,000 carbon years to sediments that hold mammoth, giant sloth, and human footprints found in the ancient Lake Otero Basin. (icr.org)
  • https://www.wikidata.org/entity/Q286954 one of three metabolic pathways for carbon fixation in photosynthesis, along with C4 and CAM. (eol.org)
