Soil organic matter is the primary determinant of soil functionality and is a source of ecosystem services critical to human well-being and nature conservancy. This volume of Advances in Soil Sciences discusses how conservation through restorative land use can increase carbon stock and soil health.

Rattan Lal, PhD, is Distinguished University Professor and Director of the Carbon Management and Sequestration Center at The Ohio State University, and Adjunct Professor at the University of Iceland and IARI, New Delhi. He was President of the WASWAC (1987-1990), ISTRO (1988-1991), SSSA (2006-2008), and the IUSS (2017-2018). He researches soil C sequestration, conservation agriculture, soil health, soil erosion and C dynamics, soil structure, eco-intensification, soil restoration, and soils of the tropics. He has authored 1,020 journal articles, authored/edited more than 100 books, mentored 370 researchers, has h-index of 163, and total citations of 120,719. In a Stanford study (Ioannidis et al. 2019, 2020), he is ranked #111 globally among world's top 2% of scientists, and #1 among scientists in Agronomy & Agriculture. Reuter Thompson ranked him #391 among the top 1000 climatologists. He holds IICA's Chair in Soil Science and Goodwill Ambassador in Sustainable Development. He is a member of the 2021 U.N. Food System Summit Science Committee and Action Track 3. He received the 2018 GCHERA World Agriculture Prize, 2018 Glinka World Soil Prize, 2019 Japan Prize, 2019 IFFCO Award, 2020 Arrell Global Food Innovation Award, the 2020 World Food Prize, and the 2021 Padma Shri Award, India.
