Assessment of soil fertility of Tal and Diara Land: A case study of Bhagalpur district, Bihar, India

Abstract

In this study the soils of the study area as per the criteria of taxonomic classification predominantly come under three orders namely, Entisols, Inceptisols and Vertisols as per 7th approximation of soils classification of Tal and Diara land of some selected district of Bhagalpur district. All the physical and chemical parameters were estimated that, the soils of ‘Tal’ which are higly clayey throughout their depth, grey in colour and low to medium availability of NPK. whereas, the ‘Diara’ land consists light texture soil and low to medium range of available NPK. Some of major soil physical constraints relating crop production and income are appropriate soil conservation measures.
