A pot experiment was conducted in Isfahan University of Technology research greenhouse to investigate the effects of sewage sludge, compost and cow manure on growth and uptake of Fe, Zn, Mn and Ni in tagetes flower. A completely randomized research with three treatments (sewage sludge, compost and cow manure at 25 Mg ha-1) and three replicates was performed. Application of organic wastes signif...
Using the isotope dilution P technique, a study was conducted to evaluate the P uptake and growth improvement of aerobic rice genotype (M9) inoculated with phosphate-solubilizing bacteria (PSB16, Bacillus sp.) and applied with Christmas Island Phosphate Rock (CIPR), and oxalic acid (OA). An absence of PSB and OA was considered as control treatment. The inoculation of PSB16 strain and OA applica...
Due to high production of organic residues such as sewage sludge and compost, land application is probably the best way to prevent accumulated residues in the environment. However, the risk involved in the land application of organic residues should be evaluated prior to the assessment of their economic and fertilizer values. The objective of this study was to evaluate the effect of organic res...
the use of metal-accumulating plants to clean the contaminated soil with toxic metals is the most rapidly developing component of phytoremediation as an environmentally friendly technology. overcoming harsh soil conditions and accelerating the recovery of degraded soils remain a worldwide restoration challenge. this study evaluated the effect of different concentrations of pb, zn, cu and fe on ...

Rhizosphere processes stimulate overyielding and facilitative phosphorus (P) uptake in cereal/legume intercropping systems. However, little is known about when and how rhizosphere alteration of legumes plays a role in improving P uptake by cereals. Wheat was grown isolated, monocropped or intercropped with faba bean in pots with low-P soil. The biomass, P content, carboxylates and phosphatases ...
the effects of an azotobacter chrococum isolate (strain ag11) and vermicompost and their combined effects on a rain-fed winter wheat (var. zagros) nutrient uptake and growth and soil water content were investigated with a farm trial. the dry matter yield was determined in 5 occasions. gravimetric soil water content, soil microbial respiration and the number of azotobacter were determined at sa...
West Africa (WA) is among the most food insecure regions. Rapid human population growth and stagnating crop yields greatly contribute to this fact. Poor soil fertility, especially low plant available phosphorus (P) is constraining food production in the region. P-fertilizer use in WA is among the lowest in the world due to inaccessibility and high prices, often unaffordable to resource-poor sub...
