Chaco Seco soil texture impacts carbon storage and production sustainability
Researchers from the National Institute of Agricultural Technology (INTA) in Salta have identified soil texture as a decisive factor for sustainable production in the Chaco Seco region of northwest Argentina.
A study led by specialists Carlos López Morillo, Laura Califano, and Jorge Chalco Vera examined how different production models affect organic carbon storage (COS), a vital indicator for soil fertility and yield. The findings reveal that carbon accumulation is not uniform across the region.
Fine-textured soils, such as clay or silt profiles, show a high potential for carbon capture when managed with planted pastures and controlled animal loads. Conversely, sandy soils are highly vulnerable to severe degradation when subjected to rainfed agriculture or unplanned livestock grazing.
The research also highlights the risks of soil compaction caused by tillage and animal trampling, which can block roots and reduce water infiltration. Experts recommend adopting conservationist practices tailored to the specific texture of each plot to ensure long-term profitability and mitigate climate change impacts.
