Zinc is presently being used as a micronutrient essential for plant growth in agriculture in the form of zinc sulphate in fertilizers. Considering the importance of nitrogen-fixing microorganisms in soil fertility and plant growth, and the toxic effects of zinc, this study aimed at isolating nitrogen-fixing microorganisms from the asparagus rhizosphere arable soil and examining the sensitivity ...

Both cereal staples and household diets can be manipulated to enhance the content of micronutrients and/or alter the levels of absorption modifiers to improve micronutrient bioavailability. Strategies described range from plant breeding, use of fertilizers and genetic engineering to changes in food preparation and processing methods at the household level involving soaking, fermentation and ger...

The study was conducted at the On Farm Research Division (OFRD) farm, Rangpur from 2002-2003 to 2004-2005 to see the effect of inorganic fertilizers along with organic manure and mungbean residue on soil properties and yield of crops. For the first crop (maize), there were five treatments. After harvest of maize, mungbean and dhaincha (Sesbania) seeds were sown as per treatments. For T. Aman ri...

The gross alpha (α) and beta (β) activities and trace heavy elemental concentrations have been determined in Single Super Phosphate (SSP) and Nitrogen Phosphorous Potassium (NPK) fertilizers samples used for agricultural purposes in Nigeria. Cultivated farm soil samples from two regions (north and south) in the country and samples of phosphate rocks were also analyzed for gross α and β radioact...

Numerous preclinical studies have suggested that micronutrient status is associated with the progression of human immunodeficiency virus (HIV) disease, but results from observational studies are still controversial. The objective was to systematically review the efficacy of multiple micronutrient supplementation on mortality and morbidity in HIV-infected adults. A comprehensive search of the Pu...

Extensive field farming and homegardening (representing an intensive resource management system) on different inclination positions were compared on the basis of soil quality and productivity of maize and Mung bean over two years, in Meegahakiula, Sri Lanka. Soil organic matter (SOM) content of homegardens was greater than in fields irrespective of the inclination and it was more pronounced in ...

Plants nutrients supply from the chemical fertilizer is the key to increasing agriculture production by enhancing the land productivity. However, the demand-supply gap of fertilizers in India has increased in recent times, thereby leading to increased dependency on imports .India imports which were about 2 million tonnes in early parts of 2000 increased to 10.2 million tonnes of fertilizers in ...

BACKGROUND Radionuclides in the phosphate fertilizers belonging to (232)Th and (238)U and (40) K are the major contributors to the outdoor terrestrial natural radiation. These radionuclides are transferred from fertilizer to food through soil. MATERIALS AND METHODS Present work deals with the alpha activity in the different parts of the potato (Solanum Tuberosum) plants grown under controlled...

patients and methods serum zn and cu level of 43 patients with brucellosis (34 men and 9 women) were compared with 43 matched healthy controls. serum micronutrient concentrations were measured by automatic absorptive spectrophotometry. results mean serum cu concentration was significantly higher in subjects with brucellosis when compared with agematched healthy controls (p<0.05). mean serum zn ...

Abstract Silicate minerals constitute the main components in silicon (Si)-rich biomass, affecting phosphorus (P) adsorption and release competencies of mineral-engineered biochar; however, mechanisms underlying their differences remain largely unresolved. To examine these interactions, we investigated mineralogical compositions quantified P-adsorption capacities Al-, Fe-, Mn-, Zn-, Mg-engineere...
