Background: The research is based on the fertility status of the soil being affected year by year so here is a strategy to save the soil fertility level or soil health by the use of a leguminous cropping system. Methods: A study was conducted during 2018-2021 in the Meerut district of western Uttar Pradesh to evaluate the soil characterization of the rice - pea- sugarcane cropping system. The soil samples were analyzed for various parameters in the laboratory. The status of available NPK in soils and other soil properties like pH, electrical conductivity (EC) and organic carbon (OC) content were assessed. Result: Results reveal that the soils of the study area were neutral to strongly alkaline in reaction and non-saline in nature. Nutrient status regarding to the available nutrient in the surface (0-15 cm) and subsurface (15-30 cm) depth of soil indicate that soils are low in available N and medium in available P and K in surface and subsurface. A positive and significant correlation of NPK with organic matter content was found while significant and negative correlations exist between the soil pH. [ABSTRACT FROM AUTHOR]

The investigations were conducted at Sardar Vallabhai Patel University of Agriculture and Technology, Meerut, Uttar Pradesh, India during March 2019 to January 2020 for isolation and characterization and identification of phosphate solubilizing microbes (PSM) in soils of northern region of India. Soil samples (0-30 cm) were collected from four locations i.e. KVK, Lohaghat, SVPUAT, Meerut, College of Agriculture field, SVPUAT, Meerut and KVK, Bulandshahar covering Uttar Pradesh and Uttarakhand states of India and kept in refrigerator for analysis. The isolation of two rhizobial bacteria isolates (S1 and S2) in conjunction with the two-phosphate solubilizing efficient fungal isolates (F1 and F2) was carried out by the serial dilution method. The study of their morphological and microscopic characters, together with Solubilization Efficiency (SE), and Solubilization Index (SI) were also assessed. Finally, the biochemical tests were run according to their nature that was gram-negative rod by using KB002 TM HI Assorted Biochemical Test Kit (for Gram-negative rods). Between the two bacterial isolates was S1 was showing more solubilization on Pikovskaya agar (PVK) compared to S4 on the 5th day of observation, while S4 gave better results on the 8th-day solubilization observation. The biochemical tests on bacterial isolates were showing disagreement between the two, proving them as completely different isolates. In the case of fungi, the F2 isolate was showing better SE and SI values compared to the F1 isolate. [ABSTRACT FROM AUTHOR]
