Assessment of the Impact of Sulphur Levels on Soil Chemical Properties in S-de icient Sandy Loam Soil of Amritsar

Limited understanding of how varying sulphur levels affect soil chemical properties in S-deicient sandy loam soil speciically found in Amritsar. A pot experiment was conducted on mustard cv. RLC 3 and broccoli cv. Palam Samridhi in a factorial completely randomized design with three replications. Four levels of sulphur were applied to the soil, and plants were harvested 30 and 60 days after germination. The study aimed to investigate the impact of sulphur levels on soil chemical properties. The results showed that the value of soil pH was reduced signiicantly with an increase in the S level. The highest soil pH (8.12) was recorded where no sulphur-1 was applied, whereas the least (7.65) was found in 60 mg S kg soil treatment. There was no signiicant variation in electrical conductivity and soil organic carbon during the study. Soil available sulphur increased linearly with a simultaneous increase in levels -1 -1 of sulphur resulting in a maximum value (12.75 mg kg ) at 60 mg S kg soil treatment, compared to no sulphur application (4.31 mg-1 -1 kg ). Notably, soil properties signiicantly improved with the application of 60 mg S kg soil, particularly under mustard followed by broccoli crop.
