The use of excess conventional Phosphorus (P) fertilizers to improve agricultural productivity, in order to meet constantly increasing global food demand, potentially causes surface and ground water pollution, waterway eutrophication, soil fertility depletion, and accumulation of toxic elements such as high concentration of selenium (Se), arsenic (As) in the soil. Quite a number of soil microor...

The present investigation deals with the role of Plant Growth Promoting Rhizobacteria and chemical fertilizers alone or in combination on urease, invertase and phosphatase activities of rhizospheric soil and also on general impact on growth of safflower cvv. Thori and Saif-32. The PGPR (Azospirillum brasilense and Azotobacter vinelandii) were applied at 10cells/mL as seed inoculation prior to s...

wheat is a staple food in pakistan. production of wheat is increased with extensive use of phosphate based fertilizers in agricultural fields. activity mass concentration of primordial radionuclides due to use of phosphate fertilizers in soil enhances the external gamma dose and due to the consumption of wheat food grown on these soils also increases the internal dose. different types of soil, ...

in order to study the effect of solitary and combined application of two types of green manure, cow manure, barvar-2 phosphate fertilizer and conventional chemical fertilizer on some of the qualitative and quantitativeproperties of sugar beet, an experiment was conducted at the research farm of shahrekord university in 2013. the experimental design was randomized in a complete block design with...

Phosphate concentrations in municipal and agricultural wastewaters continuously increase because of the growing use of detergents and fertilizers. Thus, it seems that phosphate recovery from wastewater as calcium phosphate would be attractive due to the vast applications of calcium phosphate in industry. In the current experimental study, the phosphate recovery by addition of calcium chloride t...

Phosphorus (P) deficiency in soil limits crop yields and can be managed by P fertilizers. But mere applying fertilizers alone may not effective justifying its bioavailability. At present global reserves are declining an increasing way which urges us to find out alternatives. Thus, the work was taken prepare phosphocompost using water hyacinth (Eichhornia crassipes) as feedstock, termite, normal...

considered is an important objectives of sustainable agriculture,environmental protection and achieving inclusive development.therefore it seems essential method that can reduce the excessive consumption of chemical fertilizers.the purpose of this study was to assess the impact of plant growth promoting microorganisms and effect of combination nutrition systems,chemical and bacterial on stages ...

General fertilizer practice recognizes in a vague way that there are reactions between soils and phosphatic fertilizers which affect the efficiency of the fertilizers. Bone meal, for instance, is recommended for use on open soils which are not too dry (39, p. 169), and for light soils not too deficient in phosphoric acid (3%, p. 320). Floats are recommended by Wheeler (39, p. 173) for acid soil...
