Fertilizers are often applied according to nitrogen requirement; however, recent evidence suggests that phosphorus (P) may pose as much, if not more, of an environmental threat. The objective of this research was to quantify the differences in phosphate-phosphorus losses in runoff from two organic fertilizers (poultry litter and composted dairy manure) and one inorganic fertilizer control, appl...

Synthetic (e.g. urea) and organic fertilizers (e.g. compost) differed markedly in N isotope composition and the greater the difference between organic and synthetic fertilizer the more robust will be the differentiation of crops and vegetable grown under different farming systems. The objective of this study was to compare nitrogen and carbon isotope composition of organic fertilizers and manur...

application of biofertilizers, especially plant growth promoting rhizobacteria (pgpr) is one of the most important strategies for plant nutrition compared to chemical fertilizers, especially in sustainable management of agroecosystems. in order to evaluate the effect of pesodomonas bacteria strains and chemical phosphate fertilizer on yield and yield components of wheat the kavir cultivar an ex...

PURPOSE The rate of hepatocellular carcinoma (HCC) is increasing worldwide, including in Egypt. Hepatitis B (HBV) and C (HCV) viruses are major risks. Non-B non-C HCC was reported in some countries. We investigated non-B non-C HCC-independent risk factors and associated profiles in viral hepatitis endemic region. METHODS In a consecutive series, 281 patients were diagnosed with HCC and receiv...

in order to study the effect of different organic fertilizers on quantitative and qualitative characteristics of fenugreek forage, an experiment was conducted based on completely randomized block design with six treatments and three replications at agricultural research station, college of agriculture, ferdowsi university of mashhad, iran, during 2006. the experimental treatments were four orga...

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 ...

In order to investigate the effect of different levels of biological fertilizers on potato performance (cv. Marfona), an experiment was carried out as strip plot based on RCB design with 3 replications in 2011 at Isfahan. Treatments included Nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and Nitroxin+ Phosphate at 4 levels (0+0: control, 20+100, 30+150...
