Organic carbon and stable 13C isotope in conservation agriculture and conventional systems
Conservation agriculture might have the potential to increase soil organic C content compared to conventional tillage based systems. The present study quantified soil organic carbon (SOC) and soil C derived from C3 (wheat) ...
The natural abundance of 13C with different agricultural management by NIRS with fibre optic probe technology
In the present study the natural abundance of 13C is quantified in agricultural soils in Mexico which have been submitted to different agronomic practices, zero and conventional tillage, retention of crop residues (with ...
NIR spectroscopy: An alternative for soil analysis
Advances in laboratory instrumentation and chemometrics provide alternatives to traditional methods of conducting soil chemical analysis. One of these is infrared diffuse reflectance spectroscopy in the near-infrared ...
Evaluation of three field-based methods for quantifying soil carbon
(Public Library of Science, 2013)
Three advanced technologies to measure soil carbon (C) density (g C m−2) are deployed in the field and the results compared against those obtained by the dry combustion (DC) method. The advanced methods are: a) Laser ...
Conservation agriculture, increased organic carbon in the top-soil macro-aggregates and reduced soil CO2 emissions
Background and aims: Conservation agriculture, the combination of minimal soil movement (zero or reduced tillage), crop residue retention and crop rotation, might have the potential to increase soil organic C content and ...
