Soil organic carbon losses with lateral transfer to the oceans

A spatially distributed model coupling erosion, transport, and deposition to the carbon cycle was developed. Then, it was used to simulate the impact of cover crops on both erosion and carbon, to show that cover crops can simultaneously increase organic carbon storage and reduce particulate organic carbon export to the oceans.

The use of cover crops (CCs) is a promising cropland management practice with multiple benefits, notably in reducing soil erosion and increasing soil organic carbon (SOC) storage. The historical effect of soil erosion, transport, and deposition on the soil carbon budget at a continental scale in Europe was characterized since the early industrial era, using reconstructed climate and land use forcings. Then, the impact of two distinct policy-oriented scenarios for the introduction of Cover Crops (CC) were evaluated, covering the European cropping systems where surface erosion rates or nitrate susceptibility are critical. The evaluation focused on the increase in SOC storage and the export of particulate organic carbon (POC) to the oceans, compiling a continental-scale carbon budget. The results indicated that Europe exported 1.95 TgC/year of POC to the oceans in the last decade, and that CCs can contribute to reducing this amount while increasing SOC storage. Compared to the simulation without CCs, the additional rate of SOC storage induced by CCs peaked after 10 years of their adoption, followed by a decrease, and the cumulative POC export reduction stabilized after around 13 years. Results show that CC adoption can reduce the annual export while increasing SOC storage. In a scenario of widespread adoption, CCs alone are insufficient to achieve the 4‰ target.

Title: Soil Organic carbon losses with lateral transfer to the oceans in Europe

Description: This group of data incluces: a) The net gains of carbon due to the lateral movements (as in Figure 3a); b) The net losses of carbon due to the lateral movements (as in figure 3b);c) the input of carbon to the non-eroded soil carbon (SC) pool (as in Figure 6a); d) the output of non-eroded SC due to microbial respiration (as in figure 6b); e) Amount of the non-eroded SC that is lost due to erosion (as in figure 6c); f) Gross gains of eroded SC due to the lateral movements (as in figure 6d);
g) Gross losses of eroded SC due to the lateral movements (as in figure 6e); and h) Output from the eroded SC due to microbial respiration (as in figure 6f).
