“…These results indicated that Fe was increased and Mn was decreased with increase in boron content in leaf. Similar results were reported by Alvarez-Tinaut et al [40], and Tariq and Mott [15]. They reported that Mn/Fe ratio in the plant decreases with increase in boron concentration.…”

The present study was based on the general hypothesis that boron may affect the accumulation and utilization of other nutrients in plant. For this purpose a field experiment was carried out to find out the influence of boron on the different nutrients content in FCV tobacco (Nicotiana tabacum L.) at TRS Khan Garhi, Mardan, during 2010-2011. Two varieties TM-2008 and Speight G-28 were tested and six levels of boron (0, 0.5, 1, 2, 3 and 5 kg•ha −1 ) were applied in the form of boric acid, in randomized complete block design in split plot arrangement and replicated thrice. Results indicated that the yield of tobacco crop increased with 1 kg•B•ha −1 and then decreased sequence wise in both varieties. N and P concentrations were significantly affected by applied boron. Similarly, potassium was increased which is a good indication for a better quality of tobacco crop. Application of boron significantly increased the concentrations of boron nutrients ratios such as K/B; Cl/B and Mn/Fe were decreased while K/Cl and Zn/Cu ratios were increased at lower boron concentrations but decreased at higher concentrations of boron. The fertilizer use efficiency of both the cultivars showed similar trend; however, Speight G-28 was more efficient than TM-2008 in boron accumulation. The overall results revealed that the application of boron should be encouraged for balancing nutrients concentration, thus getting higher yield in the prevailing conditions.

“…At the period of high P accumulation in the roots, high Fe, Mn, and Zn concentration were also found. Accumulation of these elements together in tomato roots has been reported (Alvarenz-inaut and Martize, 1980). High concentration of Fe and Mn cause immobilization of P in roots and together generate formation of phosphate precipitate.…”

Greenhouse tomato plants were grown hydroponically during the period of lower temperatures of winter (LT) versus the period of higher temperatures of summer (HT). In these plants, the effect of season on fruit load was dramatic. In order to study the alterations season introduces to the developmental allocation of nutrients within the various organs, concentrations of total nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu) were determined during each season at weekly intervals in the dry mass of leaves and roots and in the extract of upper, middle, and lower parts of the stem. The level of N/ P ratio was always higher in the leaves than in the roots, and these differences were more intense during HT. The short-term changes of ratio in the leaves during HT and LT were positively related with the changes in temperature (r = 0.59 and 0.51 for HT and LT, respectively). In contrast, such correlations in the root were negative (r = −0.54 and r = −0.33 for HT and LT, respectively). The increase of temperature increased P uptake but not its translocation to upper plant parts. HT affected the translocation of N, K, Mg, and Ca more and their uptake less. Fruit load differentially affected the concentration of nutrients. In contrast to total N and K, Ca concentration in plant parts presented a positive relation with the increase of fruit load. Calcium and total N concentration (as opposed to P and micronutrient concentrations) were always higher in the leaves than in the roots. Under HT conditions, P was accumulated in roots in combination with high concentrations of Fe, Zn, and Mn. On the other hand, K and N were accumulated 505 Downloaded by [UQ Library] at 00:28 02 November 2014 506 M. K. Darawsheh et al.in the roots during the period of low temperature in winter. Calcium and K compared with other nutrients presented a pronounced tendency to be transported toward the top of the stem during HT, and their extractable concentration in the upper part of stem presented a significant increase during summer. Extractable K concentration was two to nine times higher than that of the other macronutrients. Our data suggest that the extractable concentration of nutrients of the stem is a good index for the diagnosis of the mineral nutritional status of the plant.

“…This was an unexpected result, as the plant Fe usually does not increase with increasing pH of the soil. Perhaps the Fe increase was related to the antagonism of Mn-Fe (Alvarez-Tinaut, Leal, and Martínez 1980 …”

In Poland, assessment of the content of micronutrients in soil is performed using 1 M hydrochloric acid (HCl) as an extractant. The objective of this study has been to check whether 1 M HCl can be replaced by Mehlich 3. In total, 330 soil samples were taken from fields cropped with winter wheat. Each sample was accompanied by a sample of wheat plant. The samples were from four groups of soils having various pH values-from acidic to alkaline soils. The suitability of the extractants was evaluated separately for each soil group based on the significance and power of correlation between soil microelements extracted by both methods, soil and plant microelements, and the bioaccumulation factor. The HCl extractant was a better predictor of the availability of microelements to wheat than Mehlich 3 in all tested soil groups. Mehlich 3 can be applied for extraction of boron (B) and, in some cases, copper (Cu) and manganese (Mn).
