It is well acknowledged that integrated nutrient management, or INM, is a useful strategy for maintaining soil fertility and ensuring sustained crop yield. It has been demonstrated that adding organic manures to the soil improves its properties and increases the availability of nutrients. Soil samples from long-term fertilizer trials at the research farms of Dr. PDKV, Akola, Maharashtra, and VNMKV, Parbhani, Maharashtra, were gathered during the 2020–21 crop year. Samples represent six familiar treatments combinations comprising farmyard manure and chemical fertilizers. The randomized block design (RBD) was accompanied. The study intended to examine the footprint of INM on mean weight diameter (MWD) of vertisols under the Soybean-Safflower and Sorghum-Wheat cropping systems. The long-term practice of manure and fertilizers in Akola and Parbhani significantly impacted the mean weight diameter of soils under different cropping systems. The mean water depth (MWD) values in Akola and Parbhani ranged from 0.47 to 0.89 mm and 0.49 to 0.76 mm respectively, while in the subsurface layer, they varied from 0.42 to 0.79 mm and 0.44 to 0.68 mm respectively. The study found that the 100% NPK+FYM treatment in both cropping systems resulted in the highest MWD values, indicating enhanced soil aggregate stability.

From the above investigation results, it can be concluded that the application of balanced fertilizer and organic fertilizer, especially 100% NPK+FYM treatment, has significantly improved the mean weight diameter (MWD) sof Soil aggregates in sorghum-wheat and soybean-safflower growing systems and also at soil depth. This demonstrates superior aggregate stability and physical soil attributes.
