Abstract The quality of soil plays a crucial role in sustainable agriculture. To better understand the changes across different agroecosystems, long‐term experiments are considered as most effective approach. Moreover spite their significance, there is paucity information pertaining to impact fertilizer and manure application on Vertisols Central India. Thus, present study aimed assess an ongoing 46‐year experiment conducted central India, where soybean‐wheat cropping system (SWCY) was implemented Vertisol. involved inorganic integrated nutrient treatments, including farmyard (FYM). By analyzing various biological physiochemical properties soil, index (SQI) developed. SQI encompassed treatments with both optimal suboptimal dosages, revealing range variations resulting from applications over long term. found significant correlation between values grain yields soybean ( R 2 = 0.85**) wheat 0.85**). main indicators identified for assessing were large macro‐aggregates, dehydrogenase activity, microbial biomass nitrogen carbon, available nitrogen. Overall, findings highlighted importance determining quality, emphasizing significance integrating organic sources nutrients improving crop productivity sequence
