A study in the Central Plain Zone of Uttar Pradesh by Mahendra Kumar et al., published in Preprint.org website has reported that different land use systems strongly affect soil health and carbon levels. Horticulture and forest-based lands had higher soil organic carbon, better nutrients, and stronger microbial activity, while barren land had the poorest soil quality. Overall, the study shows that well-managed vegetation systems improve soil fertility and help store more carbon, making land use a key factor in sustainability.
