The present study was undertaken to assess the fertility status of soil under various cropping sequences followed in different blocks of College of Sericulture, Chintamani Campus, UAS-B. Three wings of Chintamani campus, namely College, ARS and ICAR-KVK falling under four blocks were selected. The soil samples were taken from 0-15 cm depth with the help of an auger after the harvesting of the kharif crops during 2020-21, using the GPS locations. Seventy-nine soil samples were taken in different blocks of the campus. Soil pH, electrical conductivity, organic carbon, available major, secondary and micronutrient content of soil were measured. Data were analyzed with descriptive statistics and Parker's nutrient index was used to compare the fertility level. The result revels that soils are acidic in nature; organic carbon content was low to medium while available nitrogen was medium, available phosphorous low and available potassium high. Exchangeable calcium and magnesium were high and available sulphur was low to medium. DTPA extractable zinc, iron and boron contents were deficient and sufficient ranges in the samples, copper and manganese content were sufficient in all the samples. [ABSTRACT FROM AUTHOR] |
