This study examines zinc(II)–chitosan complexes as a bio-sorbent for phosphate removal from aqueous solutions. The bio-sorbent is prepared and is characterized via Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), and Point of Zero Charge (pHPZC)–drift method. The adsorption capacity of zinc(II)–chitosan bio-sorbent is compared with those of chitosan and ZnO–c...

Ginkgo biloba L. is one of the most extensively planted and productive commercial species in temperate areas around the world, but slow-growth is the most limiting factor for its utilization. Fertilization is one of the key technologies for high quality and high forest yield. To better understand the impacts of fertilization on Ginkgo productivity, the effects of fertilization treatments (singl...

Phosphate fertilizer experiments with nonbearing citrus trees were started at planting time in commercial groves on 5 flatwoods soils. The soils included 1) Brighton peat, 2) Sunniland, 3) Keri-Bradenton, 4) Immokalee, and 5) Immokalee-Pomello. Some of the phosphate treatments were applied only once, as broadcast applications at planting time. Other treatments were applied periodically to indiv...

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 and 50+200...

introduction cultivated sunflower is one of the largest oilseed crops in the world. sunflower seed is the third largest source of vegetable oil worldwide, following soybean and canola. nitrogen is one of the most important elements for crops to achieve optimum yields and quality. phosphorus (p), next to nitrogen, is often the most limiting nutrient for crop and forage production. phosphorus ava...

Abstract Late blight disease is one of the problems faced by potato farmers. Chemical fertilizer and biological (bio-fertilizer) reported have a potential to control late disease. However, there lack research on effect combining use different types bio-fertilizers with doses chemical fertilizers in plants This study aims analyze plants. was conducted from June August Sembalun District, West Nus...

in order to investigate the effect of mycorrhizal fungi and phosphorus fertilizer on concentration of leaf nutrients and photosynthetic pigments of bean (phaseolus vulgaris l.) in condition of irrigation with saline water, an experiment was conducted based on completely randomized design with three replications in greenhouse of bahonar university of kerman, iran during 2010. the studied factors...
