Impact of waste vehicle tyres incineration and heavy metals contamination of soil in some locations in Lafia, Nasarawa State

This study was carried out in Lafia, to determine metallic pollution in soils due to incineration of tyre on the soils at different layers and the effect of pH on the heavy metals leaching. Soil composite samples were collected from 5 identified locations (Shabu, Wakwa Alhaji, Ombi1, Tudun Amba and Akurba) manually at various depths, 0-10, 11-20 and 21-30 cm using a stainless-steel hand auger. Atomic Absorption...

Revitalizing maize production through managing biological N fixation, soil acidification and nitrous oxide emission from legumes in tropics

Legume associations address challenges related to soil fertility and land degradation commonly encountered in maize monocultures. However, it's important to note that legumes contribute to the production of both nitrous oxide (N2O) and hydrogen ions (H+). In our examination of 693 manuscripts published between 1941 and 2023 to document the benefits of legumes in maize-based cropping systems, we identified and...
