A feasible way to increase carbon sequestration by adding dolomite …
For the average carbon content, dolomite or/and K-feldspar is conducive to plant growth (see Figure 1). The minerals thus improve organic carbon fixation. From a statistical point of view, only adding dolomite (d-s) or increasing the K-feldspar content (p-d-s and p-s) were beneficial to the formation of organic carbon sinks.
A feasible way to increase carbon sequestration by …
Agricultural operations affect the carbon cycle through uptake, fixation, emission, and transfer of carbon among different pools. Based on these, we added dolomite and K-feldspar into soil to investigate if these minerals can increase carbon sequestration and also improve the available potassium content.
