Some phosphate rocks (PR) contain high concentrations of uranium (U), which are potentially toxic via accumulation in soils and food chains, and plant uptake of U is likely to be influenced by characteristics of roots and associated microorganisms. The relative importance of root hairs and mycorrhiza in U uptake from PR was studied using a root hairless barley (Hordeum vulgare) mutant (Brb) and...

A UCT type pilot plant fed with synthetic wastewater was operated with influent COD/TP ratios of 18, 12 and 8 to investigate the role of intracellular storage products on EBPR mechanisms. Acetate was the sole carbon source and other nutrients were provided in excess during plant operation at an SRT value of 10 days and at 20C temperature. COD utilization, P-release and uptake, PHA and glycogen ...

This research aimed to determine the effect and best granular KCl fertilizer dosage in increasing K-available, K-Uptake, yield of sweet corn (Zea mays saccharata Sturt.) Talenta variety on Inceptisols from Jatinangor. The method used was a randomized completely block design (RCBD) with nine treatments three replications. treatment consists without fertilization as control (A; N, P, K (B); ¼ + P...

A study was conducted to characterize plant growthpromoting rhizobacteria (PGPR) of tea [Camellia sinensis (L.) O. Kuntze] and investigate the potential using them enhance growth nutrient uptake plants, also reduce use chemical fertilizers in nurseries mid-country Sri Lanka. Nitrogenfixing Azospirillum sp. (AZO) phosphate solubilizing bacteria (PSB) isolated from rhizosphere grown three main so...

• The mineral nutrition of terrestrial carnivorous plants was investigated under glasshouse conditions to elucidate ecophysiological adaptations of this plant group. • In Drosera capillaris and D. capensis, absorption of N, P, K, and Mg from insects was relatively efficient (> 43%), whereas that of Ca was not. Carnivorous plants (D. capensis, D. peltata, D. scorpioides, and Dionaea muscipula) e...
