in order to study the effect of fertilizer management on summer savory production, a field experiment was conducted at the agricultural research station, college of agriculture, ferdowsi university of mashhad, iran during growing season of 2009. a randomized complete block design with three replications was used. treatments included: 1) nitroxin biofertilizer 2) phosphate solubilizing bacteria ...

Phosphorus (P) is a critical nutrient that plays an essential role in improving soil fertility for optimum plant growth and productivity. It one of the most deficient macro-nutrients agricultural soils after nitrogen considered inadequate production. To P availability soils, farmers are applying huge amounts synthetic fertilizers adversely affect wider environment, groundwater, microbial popula...

BiofertiJizers are microbial preparations containing living cells of different microorganisms which have the ability to mobilize plant nutrients in soil from unusable to usable form through biological process. They are environmental friendly and play significant role in crop production. Previollsly it is mainly used for field crops but now-a-days it is used for fruit crops also. Biofertilizers ...

The use of plant growth promoting bacterial inoculants as live microbial biofertilizers provides a promising alternative to chemical fertilizers and pesticides. Inorganic phosphate solubilization is one of the major mechanisms of plant growth promotion by plant associated bacteria. This involves bacteria releasing organic acids into the soil which solubilize the phosphate complexes converting t...

BACKGROUND AND OBJECTIVES Azotobacter is a diazotroph bacterium reported to possess various plant growth-promoting characteristics.The aim of this study was to isolate Azotobacter strains capable of fixing nitrogen and effectively hydrolyzing both organic and inorganic Pi compounds. MATERIALS AND METHODS In this study, soil samples collected from a diverse range of slightly alkaline soil type...

nterest in organic fertilizers is growing in the greenhouse industry, but experience and trials are not keeping up. There is little information available on how well the new types of fertilizers provide nutrition for plants compared to traditional water-soluble chemical fertilizers. The most widely available “organic” fertilizers for application like traditional water-soluble fertilizers are fi...

The commodity market super-cycle and food price crisis have been associated with rampant food insecurity and the Arab spring. A multitude of factors were identified as culprits for excessive volatility on the commodity markets. However, as it regards fertilizers, a clear attribution of market drivers explaining the emergence of extreme price events is still missing. In this paper, we provide a ...
