    Notes: Summary The ion exchange behavior of heavy metals (Cu, Zn, Ni, Cd) in soils is shown to be strongly influenced by complex formation with tetraethylenepentamine (tetren). In a heavy clay (illite) soil, the metal (complex) concentration in the equilibrium solution is lowered by some two orders of magnitude, as compared to the aqueous metal ions. In a sandy loam, in which the exchange properties are nearly exclusively due to organic matter, the addition of tetren leads to a significant increase of the metal (complex) in solution. These effects are interpreted in terms of the high adsorption selectivity of the metal complexes for clay particles (illite clay) and the competition of tetren with the chelating groups of the humic fraction (sandy loam). In this case the resulting tetren complexes remain in solution and can be immobilized by addition of small amounts of clay to such a soil.

    Notes: Summary The consequences of complex formation with tetren (tetraethylenepentamine) for the uptake and mobility of copper in the plant is studied. Short term supply of double labelled Cu-tetren (64Cu,14C-tetren) in nutrient solution to corn plants (Zea mays L., cv. spec.) indicates a stoichiometric uptake of the 1-1 complex. This is reflected in the increased shoot/root ratio of the64Cu-content (two orders of magnitude) resulting from an enhanced mobility of the complexed Cu in the plant. Increasing Cu-concentrations reduce the uptake of tetren, and an interaction between the uptake of tetren and Cu-tetren is demonstrated. The changed mobility of the64Cu-tetren complex is shown in more detail using cut shoots of papyrus plants (Cyperus papyrus L. cv. spec.) andin vivo detection of the64Cu radiation during transport. Results are discussed in terms of the effect of complex formation on the cation exchange process during xylem transport.

    Soil moisture influence on micronutrient cation availability under aerobic conditions (1983)
    Springer

    Notes: Summary The three major soil series comprising the Gezira scheme (Sudan) are Hosh, Suleimi, and Laota. Surface soil samples from each soil series were employed to study the effect of soil moisture on the DTPA-extractable micronutrient cation under aerobic conditions. The study continued for 8 weeks using an incubation technique at two levels of soil moisture (continuously moist and moist/dry cycles). The DTPA-extractable Cu, Fe, Mn and Zn from air-dry soil samples were much higher compared to values from their incubated counterparts. For the three soils the CO2 production (microbial activity) reached the maximum in 5 weeks and then levelled off while the lowest values of micronutrient cation from the incubated soils were obtained between 2 to 8 weeks. Generally, the study suggests that the hot dry months preceding crop growth should increase clay surface acidity and hence availability of mironutrient cations.

    Cu and Zn in soils treated with sewage sludge: Their ‘extractability’ to reagents compared with their ‘availability’ to plants (1983)

    Notes: Summary Dried digested sewage sludge (cake) was mixed, in varied proportions, with three contrasting soils and cropped intermittently to ryegrass or young barley over a period of 710 days. Results are presented for periods 1–4, 13–16 and 22–23 months after the sludge and soil were mixed. At any given time the quantities of Cu or Zn that wereextractable (by EDTA or acetic acid) from a given soil showed a simple relationship to the ‘total’ quantities of Cu and Zn present. Theavailability of these elements to test crops also showed a simple relationship to their ‘total’ quantities. As a result the quantities available or extractable at any given time appeared to be related to each other also. However, though the extractabilities of Cu and Zn changed with time in some cases, and the availabilities of Cu and Zn changed with time in some cases, the changes were not matched. Increased extractability did not necessarily lead to increased uptake, and in some cases uptake increased even when extractability did not. It should not be assumed too readily therefore that because, at a given time after a soil is sludged, the quantities of added Cu and Zn that are extractable or available are sometimes correlated, the former actually measures the latter.There is no reason to assume that extractants remove all or only the forms of combination of Cu or Zn that may be taken up by crops.

    Notes: Summary Complex formation of copper with tetraethylenepentamine (tetren) has some pronounced effects on the rate of uptake of the metal in corn, grown on nutrient solutions. At normal copper levels (0.02 ppm) in the medium, complex formation leads to a nearly hundredfold decrease in the rate of uptake, growth rate being slightly improved. Similar effects are observed at high copper levels (0.05 and 1 ppm) in which case the growth rate, severely affected in the absence of tetren, can be restored to normal values. High excess of tetren in the medium leads to copper-deficiency. Evidence is presented that the metal is taken up and translocated to the shoot as a metal complex and that its rate of translocation through the xylem is higher than for the aqueous ion. The effects in the case of zinc are similar although somewhat less marked.

    Notes: Abstract Plant genotypes differ in their uptake, translocation, accumulation, and use of mineral elements. Examples of genotype differences to iron, nitrogen, phosphorus, potassium, calcium, magnesium, manganese, boron, copper, zinc, and molybdenum are discussed. Current knowledge is sufficient to indicate that many crop plants can be improved for the efficient use of mineral elements and better adaptation to mineral stress conditions.

    Notes: Summary The rates of uptake of nutrients from solution by apple roots were measured (a) in a root laboratory, using intact roots of mature trees growing under field conditions and (b) in controlled environment using young trees. Maximum nitrate inflows into Discovery/M.9 roots under field conditions were only slightly lower than those into roots of the same genotype in controlled environment, but up to 80 times lower than those into roots of Worcester Pearmain seedlings. At any given external P concentration, P inflows into roots of field-grown trees were about 2.5-times lower than those into the roots of young trees in controlled environment. Nitrate inflows were constant above a solution concentration of 20 mmol m−3 in both field-grown and small trees. In both cases, phosphate inflows increased linearly with solution concentration up to 10 mmol m−3. Among the various plant and environmental factors influencing nutrient uptake characteristics of apple roots were: the scion genotype, tissue nutrient levels, root origin, the form in which N is supplied, level of irradiance of the shoot, root temperature and the season of the year. The effects of these factors are illustrated with examples.

    Notes: Summary Of 20 Dutch soils, concentrations in the soil solution and total contents of Zn, Cd, Pb and Cu were determined. In addition, distribution constants were measured for Cd and Pb. Soil solution concentrations of the heavy metals as well as their total contents in the soil and exchangeable fraction, calculated with the distribution coefficients, were compared with uptake in vegetables grown in pots. Log-log plots of concentrations in the plant and the soil solution concentrations showed the best correlation for Cu, Cd and Zn. Increasing Zn appeared to increase Cd uptake at high solution concentrations of Cd and to decrease uptake at low solution concentrations. For Pb generally no significant relationship between plant uptake and soil solution concentration or any other soil parameter for Pb could be found.

    Notes: Summary The absorption, distribution and concentration of Cu in white clover were examined in plants grown on 21 soils under controlled environment conditions, and the results compared with those from a previous study with perennial ryegrass. The clover absorbed more Cu and, in general, had higher concentrations in the shoots over six successive harvests than did the ryegrass. However, concentrations of Cu in the roots, and the proportion of the total plant Cu found in the roots were lower with the clover. The concentration of Cu in the shoots of the clover, and the total amount in shoots plus roots, respectively, were correlated with the concentration of Cu extracted from the soils by 0.05M EDTA (r=0.473 and 0.700), by 0.005M DTPA (r=0.610 and 0.638) and by 1.95 per cent HNO3 (r=0.627 and 0.699). Some of these correlations were improved slightly when the concentrations of extractable Cu were adjusted for soil pH. The exploration of the soils by root extension appeared to be less important in the acquisition of Cu by the clover than it was for the ryegrass.

    Total concentrations of Mn, Zn and Cu in certain forest soils in Greece (1983)
    Springer

    Notes: Summary Total concentrations of Mn, Zn and Cu were determined in soil samples from 144 profiles located in remote forested areas throughout the mainland of Greece. Bio-accumulation of Mn and Zn in the humic horizon took place only in moderately acid soils (pH 5–6). Mean concentrations of Mn, Zn and Cu, in the mineral section of the soil profiles, were 1383, 93, and 51 ppm, respectively. Soils from hard limestone and basic and ultrabasic igneous rock contain these three minor elements at significantly higher concentrations compared to soils from the rest of the soil parent materials. In most of the soil profiles concentration of Cu increased, and of Mn decreased, with soil depth. Concentrations of Mn, Zn and Cu in the underlaying “rocks” were within the range of their average concentrations found in the mineral soil, except for hard limestone where much lower concentrations of these elements have been found. The latter supports the theory that the parent material of soils associated with limestones might not be a solution product of the limestone rock.
