There is much more carbon stored in Earth's soil than in its atmosphere. A significant portion of this soil carbon is in organic form (carbon bound to carbon), called soil organic carbon (SOC).

Often, the soil collected for routine nutrient analysis exceeds the amount needed for laboratory nutrient analysis. Rather than discarding the excess soil, it can be placed into another sample bag for ...

Researchers have evaluated strategies for efficiently estimating soil organic carbon in agricultural fields. Quantifying soil organic carbon stocks in agricultural fields is essential for developing ...
