“…For other elements, dried samples (ca. 500 mg) were digested in acid (Nabrzyski and Gajewska 1998) and contents of K, Ca, Mg, Fe, Mn, Cu, and Zn in the digest were measured using atomic absorption spectrometry (Varian SpektrAA 300, Vienna, Austria) (Beaty and Kerber 1993). P was analyzed by a spectrophotometer (Varian DMS 200) (Cavell 1955).…”

Arbuscular mycorrhiza fungi (AMF) colonize roots of host plants and promote plant growth due to improved uptake of nutrients. While the effects on P uptake are well known, the relevance of AMF for the uptake of other nutrients is less investigated. In the present paper we studied contents of N, P, K, Ca, Mg, Fe, Mn, Cu, and Zn in the legume chickpea in pot experiments during two seasons. Beside the control, the following treatment combinations: (i) the inoculation with the commercial AMF product 'Symbivit ® '; (ii) soil sterilization before inoculation, and (iii) mineral nitrogen application. A moderate level of AMF colonization (18-55% of roots), enhanced the nutrient uptake of chickpea. With P, Mn, and in 2006 also with K, Cu, and Fe the nutrient concentrations were also elevated, even along with a simultaneous increase in plant biomass. Soil sterilization or fertilization with N showed no significant effect on nutrient uptake and biomass production.

“…The concentration of nitrogen in the samples was determined using an element analyzer based on the Dumas principle (LECO CN). For the plant tissue concentration of other elements, the dried sample (500mg) was digested in a tri-acid (HNO3 + HClO4 + H2SO4) mixture (Nabrzyski and Gajewska, 1998). K content in the digest was measured using atomic absorption spectrometry (Varian SpektrAA 300) (Beaty and Kerber, 1993).…”

The use of chemical inputs in agriculture has a negative influence on the environment. Application of chemical fertilizers (F) can be reduced by using bio-fertilizers like arbuscular mycorrhizal fungus (AMF) and Rhizobium (R). Chick pea was co-inoculated and grown in the greenhouse and in the field to investigate their effect on growth and yield. All assessed plant growth parameters were found to be highest in plants treated with AMF and Rhizobium after three months of growth. Plants treated with R+AMF+F had greater average shoot length, stem girth, shoot dry weight, root dry weight, shoot fresh weight, branch per plant, and number of pods than those treated with R+M. However, R+M had a higher number of nodules than R+AMF+F in the greenhouse, and for co-inoculation in the field, indigenous rhizobium and AMF with fertilizer application had the highest shoot length (82.0±2.3), number of pods (75.0±2.6), dry weight (109.5±11.2), 100 seed weight (14.2±0.2), and husk weight (12.06±0.2) when compared to the control. Furthermore, root colonization ranged from 63.7±2.9% to 85.0±8.1% for all AMF infected treatments. In the green house, the maximum spore density (560.0±17.3 spore/50g dry soil) was recorded for solitary mycorrhiza inoculated chickpea. As a result, it is determined that dual inoculation of the pulse with AMF and Rhizobium, both with and without NPK treatment, increased growth and production. This suggests that smallholder farmers may be able to use bio-inoculants to boost chickpea output.

The previously widespread mercury cell technology in chlorine production has now been replaced by more environmentally friendly membrane cell electrolysis which is a Best Available Techniques (BAT) technology. However, this requires a much cleaner brine containing contaminants (Al, Ca, Mg, etc.) in the order of ng/g at most. For this reason, it’s very important to detect trace amounts of aluminum in concentrated saline media in the simplest and fastest way. To the best of our knowledge, no one has previously developed a spectrophotometric method capable of detecting aluminum in ionic forms selectively in the order of ng/g in concentrated saline media, without any preconcentration or separation step. Our advanced analytical method provides an opportunity for this. During the analytical procedure, a colored complex ion is formed from the dissolved aluminum content of the sample with eriochrome cyanine R (ECR) ligand in buffered pH medium. The sensitivity of the measurement is increased by adding quaternary ammonium salt. The colored complex ion is formed in 15 minutes, then the absorbance measurement can be performed for 90 minutes. The effect of rock salt interference was eliminated by proper calibration. In our work the dependence of the signal on temperature, pH, time elapsed after the addition of reactants, the dosing sequence, the salinity of the medium was examined, furthermore, we studied which wavelength-absorbance values give the best fit (highest R2 value) and the highest sensitivity in case of linear calibration. Surprisingly, increasing the salinity significantly improves the sensitivity of the measurement.
