Following initial screening, 22 fungi and 39 bacteria from Tanzania's Minjingu and Panda Hill phosphate rock deposits were assessed for their ability to solubilise water-insoluble phosphate rocks.

In this study, rock phosphate enriched composts was prepared by mixing rock phosphate with Farm Yard manure (FYM), Poultry manure (PM), Sugar press mud (SPM) with effective microorganism (EM). For this, an experiment was carried out to determine the concentrations of total C, total N, P, K, Fe, Zn, organic matter (%) and C:N ratio of …

Two staple foods (maize and mung beans) which were cultivated in Minjingu village, where there is phosphate deposit in Tanzania, were collected directly from the farms. The activity concentrations of 226 Ra, 228 Th and 40 K were determined in the maize and mung beans samples using γ ray spectrometry employing HPGe detector of relative ...

Minjingu deposits are formed by the excreta and dead bodies of cormorants and other birds that roost and die in the mountains, forming biogenic rock phosphate or guano deposits.

Even under semi-arid environments, responses of about 57% are obtained. When moisture is inadequate, DAP and YaraMila CEREAL fertilizers are better sources of phosphate than the now replaced Minjingu Mazao fertilizer because it had low phosphate rock solubility (Savini et al., 2015), which could lead to a 10% yield reduction compared …

On the other hand, the radiation dose from ambient air over five years at the phosphate mine ranges from 1375 to 1475 nGy h -1 with an average of 1415 nGy h -1 . The average is about 28 times that of the global average background radiation from terrestrial sources, and about 12 times the allowed average dose limit for public exposure over five ...
