Aims We quantified the relative significance of phosphorus (P) availability quantity and rate of P desorbed to plant growth using ion exchange membranes on three soils (0–10 cm), initially under native vegetation and converted to either cropping, pasture, or plantation for up to 115 years. Methods Soil P availability parameters were measured by the widely used sodium bicarbonate test (Colwell P), anion exchange membranes and a...

Sulfur (S) is an essential plant nutrient, but ongoing decreases in inorganic S inputs to soil continue to reduce S availability in agricultural soils globally. This study investigated long‐term trends in soil S speciation after land use change and the application of different soil amendments using the world's longest‐running agricultural experiments at the Rothamsted Research Centre, UK. Soil samples spanning 145 years were o...

Purpose Accurately assessing soil organic carbon (SOC) content is vital for ecosystem services management and addressing global climate challenges. This study undertakes a comprehensive bibliometric analysis of global estimates for SOC using remote sensing (RS) and machine learning (ML) techniques. It showcases the historical growth and thematic evolution in SOC research, aiming to amplify the understanding of SOC estimation t...

Understanding the cycling of C and N in soils is important for maintaining soil fertility while also decreasing greenhouse gas emissions, but much remains unknown about how organic matter ( OM ) is stabilized in soils. We used nano‐scale secondary ion mass spectrometry (Nano SIMS ) to investigate the changes in C and N in a Vertisol and an Alfisol incubated for 365 days with 13 C and 15 N pulse labeled lucerne ( Medicago sativ...
