Transformation of humic substances in vermicomposting: Structural changes and impact on cowpea soil nutrient dynamics 16

This study assesses the elemental and structural transformation of municipal solid waste (MSW) by vermicomposting at different stages of maturation and evaluates its nutritional potential on rhizosphere soil chemistry compared with NPK fertilizer. The structural characterization of MSW vermicompost at increasing maturity stages was determined by solid-state nuclear magnetic resonance (NMR) and Fourier Transform infrared...

Prevalence of heavy metals along rainfall gradient in sorghum-based cropping system in the Sudano–Sahelian Zone of Nigeria

One major thing Nigerian farmers give more emphasis on is the maintenance of soil fertility. This is done indiscriminately using any material the farmers perceive could maintain soil fertility. Many of such materials like refuse dumps, industrial wastes, household wastes, and farmyard manure are applied to maintain soil fertility oblivious of their chemical contents. From Kofa, southern Kano, to Zangon Daura at the...
