Evaluation of three field-based methods for quantifying soil carbon
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 ...
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) ...
Conservation agriculture and soil carbon sequestration: between myth and farmer reality
Improving food security, environmental preservation and enhancing livelihood should be the main targets of the innovators of today's farming systems. Conservation agriculture (CA), based on minimum tillage, crop residue ...
Straw management, crop rotation, and nitrogen source effect on wheat grain yield and nitrogen use efficiency
Nitrogen fertilizer management from different sources and annual crop rotations are important components of wheat (Triticum aestivum L.) production systems, especially where air and soil quality issues have prompted a ...
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 ...
Straw management, crop rotation and nitrogen source effect on carbon and nitrogen dynamics: A laboratory study
Straw incorporation, crop rotation and organic fertilizer applications have been proposed to counter the negative effects of straw burning, inorganic N fertilizer application and intensive agriculture practices for wheat ...
