Compost

“C and N mineralization following organic amendment additions varied at different soil moisture levels. While biochar and compost can increase GHG emissions, optimizing water management can help reduce GHG emissions.”

“Biochar application reduced cumulative N2O–N and CH4–C emissions by 52% and 16%, respectively. Biochar-treated soil had the lowest cumulative N2O–N and CH4–C emissions, reducing net global warming potential (GWP) by 43% and 30%, respectively, compared to compost-treated soil and control”

“Twenty-seven years of organic no-till in central Ohio, comparing compost, manure, cover crop and fallow treatments, produced measurable differences in soil physical quality — bulk density, penetration resistance, water-stable aggregates, saturated hydraulic conductivity, organic carbon and plant-available water — at two depths, combined into a single soil physical quality index. The dataset offers a rare long-term benchmark for how organic amendments and continuous cover shape soil structure and water-holding ability.”

“After 27 years of no-till in central Ohio, annual cow manure (23.3 Mg/ha/yr) gave the highest plant-available water capacity in the top 20 cm (5.14 cm) and the highest surface water content (44.4% at pF 1.8) versus 35.8% under cover crops, mainly by building storage (meso) pores and lowering bulk density. Compost showed poorer pore-structure response, suggesting clogged mesopores, so manure was the more reliable amendment for improving water delivery.”

“Manure management in the United States must move from a disposal-based model to a circular resource framework that integrates nutrient recovery, emission mitigation, precision application, supportive policy, and site-specific decision-making.”

“After 27 years of no-till in central Ohio, compost and manure raised topsoil (0-20 cm) carbon stocks about 66%-67% above fallow, with compost sequestering 0.85 Mg C/ha/yr and manure adding the most nitrogen (0.061 Mg N/ha/yr); cover crops alone gave a smaller 21%-27% gain. Higher soil carbon tracked better aggregate stability (R2 = 0.76) and lower bulk density, though compost also pushed up salinity near the surface.”
