“…The corresponding SAI was derived from the SAI:LAI ratio of Yienger and Levy (1995). NO captured from the atmosphere is uptaken by the plant system either by direct incorporation into the leaf tissues or by the roots after absorption into the soil (Yoneyama et al, 1980). Since the precise mechanisms underlying these two routes is uncertain and fall outside the scope of this study, we assumed that all captured NO is returned to the soil directly as NH4 + .…”

Abstract. Surficial enhanced rock weathering (ERW) is a land-based carbon dioxide removal (CDR) strategy that involves applying crushed silicate rock (e.g., basalt) to agricultural soils. However, unintended biogeochemical interactions with the nitrogen cycle may arise through ERW increasing soil pH as basalt grains undergo dissolution that may reinforce, counteract, or even offset the climate benefits from carbon sequestration. Increases in soil pH could drive changes in the soil emissions of key non-CO2 greenhouse gases, e.g., nitrous oxide (N2O), and trace gases, e.g., nitric oxide (NO) and ammonia (NH3) that affect air quality, and crop and human health. We present the development and implementation of a new improved nitrogen cycling scheme for the land surface model Community Land Model v5 (CLM5), the land component of the Community Earth System Model, allowing evaluation of ERW effects on soil gas emissions. We base the new parameterizations on datasets derived from soil pH responses of N2O, NO and NH3 of ERW field trial and mesocosm experiments with crushed basalt. We successfully validated simulated ‘control’ (i.e., no ERW) seasonal cycles of soil N2O, NO and NH3 emissions against a wide range of global emission inventories. We benchmark simulated mitigation of soil N2O fluxes in response to ERW against a sub-set of data from ERW field trials in the U.S. Corn Belt. Using the new scheme, we provide a specific example of the effect of large-scale ERW deployment with croplands on soil nitrogen fluxes across five key regions with high potential for CDR with ERW (North America, Brazil, Europe, India, and China). Across these regions, ERW implementation led to marked reductions in N2O and NO (both 18 %) with moderate increases in NH3 (2 %). Our improved N-cycle scheme within CLM5 has utility for investigating the potential of ERW point-source and regional effects of soil N2O, NO and NH3 fluxes in response to current and future climates. This framework also provides the basis for assessing the implications of ERW for air quality given the role of NO in tropospheric ozone formation, and both NO and NH3 in inorganic aerosol formation.

Fertilizers in the broadest sense are products that improve the levels of available plant nutrients and/or the chemical and physical properties of soil, thereby directly or indirectly enhancing plant growth, yield, and quality. Fertilizers are classified in terms of their chemical compounds. Straight fertilizers generally contain only one primary nutrient. Compound fertilizers contain several primary nutrients and sometimes micronutrients as well. Micronutrient fertilizers contain nutrients required in small quantities by plants, as opposed to macronutrients. They are also classified as solid or liquid fertilizers and as soil or foliar fertilizers, the latter being applied exclusively by spraying on an existing plant population.
