Abstract Enhanced rock weathering (ERW), the application of crushed silicate to soil, can remove atmospheric carbon dioxide by converting it (bi) carbonate ions or solid minerals. However, few studies have empirically evaluated ERW in field settings. A critical question remains as whether additions might positively negatively affect soil organic matter (SOM)—Earth’s largest terrestrial (C) pool and a massive reservoir nitrogen (N). Here, three irrigated cropland trials California, USA, we investigated effect meta-basalt on different pools (i.e., mineral-associated matter, MAOM, particulate POM), active microbial biomass, community composition. After 2 years additions, MAOM stocks were lower upper surface (0–10 cm) plots with compared unamended control plots. At sites where baseline pre-treatment data available, neither total SOC nor SON decreased over study accrual rate MAOM-C MAOM-N at 0–10 cm was vs. controls. Before is deployed large scales, our results suggest that should assess effects SOM pools, especially multi-year time scales environmental contexts, accurately changes net C understand mechanisms driving interactions between cycling.

The labile fractions of organic carbon (OC), which are a reflection the properties soil and its use, appear to be suitable parameters for their use as indicators. aim this study was determine reliable relatively simple indicators detecting chemical physical stabilizations OC, would respond sensitively land use. includes forest ecosystem (FE) agroecosystem (AE) with different tillage intensities (reduced tillage, RT conventional CT) on real farms. Parameters C N were tested. For depth < 0.1 m in FE, hot water extractable (HWEOC) stabilization nitrogen (NL) most Higher values HWEOC indicate OC by decreasing decomposition, pH or increasing carbonates, recalcitrant fractions, higher NL incorporation into silt fraction larger macro-aggregates. In AE RT, these pool index (CPI) lability (LIC) stabilization. CPI LIC formation size-optimal dry-sieved (DSA; 1–3 mm) wet-sieved (WSA; 1–2 aggregates. CT, it NL.
