Figure Lengend Snippet: MP1 promotes soil inorganic carbon formation and increases soil fertility. (a) Image of the mesocosm setup with 7‐week‐old corn plants. (b) Soil inorganic carbon (SIC) is measured as calcium carbonate equivalent (CCE) in the leachate and soil. (c) Organic matter and (d) total carbon on MP1 and untreated control (UTC) soils. (e) Exchangeable calcium, (f) exchangeable magnesium, and (g) exchangeable iron were measured in MP1 and UTC soils, and the same cations were measured as soluble cations in MP1 and UTC's leachates. The y ‐axis shows cation concentration in ppm. For the leachate results, ppm represents milligrams per liter of leachate, whereas for the soil results, ppm represents milligrams per kilogram of soil. (h) Cation exchange capacity (CEC) on MP1 and UTC soils. For (b)–(h), each bar represents the average of six biological replicates and its standard error. The asterisks (*) indicate statistically significant differences against UTC (* p ‐value < 0.05 and ** p ‐value < 0.01).

Figure Lengend Snippet: MP1 field application increases soil carbon and positively affects soybean yield. (a) Inorganic carbon formation (measured as calcium carbonate equivalent, CCE). (b) Total carbon changes, (c) exchangeable calcium changes, (d) cation exchange capacity (CEC) changes, and (e) soil pH changes during the 2022 growing season on soybean fields. Each bar represents the average change between pre‐plant and post‐harvest on untreated control (UTC) fields and MP1‐treated fields. For all the soil results (a–e), the bars represent the average of 24 sampling points taken from six UTC fields and 23 sampling points taken from eight MP1‐treated fields and their standard error. (f) Soybean grain yield from 12 fields in North Dakota in the 2022 growing season. The MP1 bar represents the average of seven treated fields and its standard error, and the UTC bar represents the average of five untreated fields and its standard error. The asterisks (*) indicate statistically significant differences against UTC (* p ‐value < 0.05).
