Potential toxic metal (PTE) accumulation in soil and water is one of the major sources food crop contamination. PTE remediation from can be enhanced by addition organic matter to growing media. An experiment was carried out investigate effect different amendments on PTEs pea plant grown mine degraded soils. Mining soils chromite (CM), soap stone (SSM), manganese (MM), quartz (QM) were mixed wit...
This experiment was done to determine the effectd of growth stage on chemical composition and processing by NaOH and CaOH2 on ruminally degradability of Haloxylon sp. pasture plant in seeding stage. The enough amount of Haloxylon in 3 vegetation stages was prepared from Amari SarChah in May and October and December of 2010. The chemical composition of Haloxylon sp. was determined in three stage...
Archaean komatiites of the greenstone belt in Manica area, western Mozambique contains accessory amount of disseminated chromite grains. The komatiite rocks comprise peridotitic and basaltic komtiite. These komatiites are affected by regional metamorphism as all of the studied area. It is observed that only chromian spinel is preserved as the primary mineral and that all the other primary miner...
