    Zinc-phosphorus relationship in the nutrition of corn plants (Zea mays L.) grown on some calcareous soils (1981)
    Springer
    Plant and soil 59 (1981), S. 51-59 
    Details
    ISSN: 1573-5036
    Keywords: Calcareous soils ; Corn ; P ; Zea mays ; Zn
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Positive relationships were observed between Zn and P in the studied calcareous soils and in the corn plants grown thereon. The high content of carbonates in these soils affected greatly the levels of extractable Zn and the Zn−P relationships. In the pot experiment, application of P increased the Zn content of the corn plants and application of Zn increased that of P.

    Influence of waterlogging and lime or organic matter additions on the distribution of trace metals in an acid soil (1981)
    Springer
    Plant and soil 59 (1981), S. 317-326 
    Details
    ISSN: 1573-5036
    Keywords: Acid soil ; Complexed metals ; Iron ; Iron oxides ; Lime ; Manganese ; Manganese oxides ; Organic matter ; Redistribution ; Trace metals ; Waterlogging
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary A study has been made of the influence of waterlogging on the distribution of trace metals between the various reservoirs in which they are held in a soil. Selective extractants have been used to remove metals held in 4 ways: soil solution and exchangeable; specifically adsorbed by inorganic sites; adsorbed or chelated by organic sites; adsorbed onto oxide surfaces. Waterlogging over a period of 16 weeks resulted in the release of both manganese and iron from the organic — and oxide — bound reservoirs to the soluble, exchangeable and inorganic reservoirs. Addition of both 1% dried grass (as an actively decomposing organic material) and 1% CaCO3 to the soil resulted in an acceleration of the metal redistribution. For manganese, selective extraction methods accounted for the distribution of all the metal in the reservoirs studied. In the case of iron however, there appeared to be some release from a reservoir not being extracted.

    Proteoid root morphology and function inLupinus albus (1981)
    Springer
    Plant and soil 60 (1981), S. 143-147 
    Details
    ISSN: 1573-5036
    Keywords: Acidity ; Iron ; Lupinus albus ; Manganese reduction ; Proteoid roots ; Root exudates
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Current theories of phosphorus uptake by plants imply that they can augment diffusion to their root axes by the development of abundant root hairs or mycorrhizas. Some phosphorus efficient plants have root morphology with multi-branched roots and localised regions of densely packed root hairs, which we suggest is better suited to the retention of substances exuded by the roots than uptake of substances moving to the root by diffusion. Evidence of substantial exudation by the proteoid roots ofLupinus albus is presented.

    Effect of calcium carbonate and organic matter on the growth and concentration of iron and manganese in sorghum (Sorghum bicolor) (1981)
    Springer
    Plant and soil 60 (1981), S. 295-300 
    Details
    ISSN: 1573-5036
    Keywords: Calcium carbonate ; Iron ; Manganese ; Organic matter ; Sorghum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The effect of CaCO3 and organic matter on the availability of iron and manganese was studied on sorghum (Sorghum bicolor). Addition of calcium carbonate caused significant decrease in dry matter and grain yield. But yields tended to increase with the addition of organic matter at the rate of 15 t/ha. The iron concentration decreased with the addition of CaCO3 at all the stages of crop growth. Like iron, concentration of manganese also decreased with the increase in added CaCO3. Organic matter increased the iron concentration both at seedling and flowering stage. The concentration of manganese was, however, dependent on the stage of the crop.

    Transformations in plant-available forms of iron and manganese as influenced by manuring and cropping under irrigation (1981)
    Springer
    Plant and soil 62 (1981), S. 323-325 
    Details
    ISSN: 1573-5036
    Keywords: Cropping with irrigation ; Iron ; Manganese ; Manure ; Transformations of Fe and Mn
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Vertisols from field plots fertilized continuously with P, K, FYM alone and in combination at the rate of 60 kg P2O5, 30 kg K2O and 1.5 ton FYM per ha were tested for different forms of Fe and Mn as a consequence of continuous cropping with sorghum and wheat. The transformations that occurred in different forms of plant-available iron were greater than those of Mn. Exchangeable and easily reducible Fe contents were markedly influenced by treatments. In manganese, transformations of easily reducible to exchangeable forms were conspicuous.

    Boron, copper, iron, manganese and zinc contents in leaves of flowering sunflower plants (Helianthus annuus, L.), grown with different boron supplies (1981)
    Springer
    Plant and soil 62 (1981), S. 461-464

    ISSN: 1573-5036
    Keywords: Boron ; Copper ; Iron ; Manganese ; Zinc ; Microelements ; Sunflower
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Boron, copper, iron, manganese and zinc concentrations were measured in sunflower leaves from plants grown hydroponically in a closed continuous flow system and with boron concentrations ranging from deficient to toxic. Leaves were analyzed at the stage of flower development. There was a highly significant inverse correlation between B concentration in solution and Mn concentration in leaves. Cu, Fe and Zn concentrations in the leaves were not changed by the different B levels, although the B concentration in leaves increased with an increasing concentration in solution, showing a close correlation each other.

    Co-ordination of growth phenomena within a root system of intact maize plants (1981)
    Springer
    Plant and soil 63 (1981), S. 65-72 
    Details
    ISSN: 1573-5036
    Keywords: Growth co-ordination in roots ; Seminal roots ; Crown roots ; Zea mays
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Conclusions The experimental results presented show that within the intact plant growing undisturbed a serious competition exists between various root members. When as a consequence of partial derooting or local inhibitory treatments shoot growth is not affected the remaining root members compensate completely for the reduction elsewhere. Competition for a limited supply of carbohydrates covers most of the observations [1]. However, since it has been shown that with the phloem stream various hormones are transported to the roots, some of which may affect root growth [4, 5], the ultimate solution needs additional experimentation [10]. In case of the differences in the rate of root elongation in nitrogen deficient plants and in plants well-supplied with nitrogen, the higher auxin content in the latter may be responsible for the lower elongation rate [5].

    The influence of mechanical resistance and phosphate supply on morphology and function of corn roots (1981)
    Springer
    Plant and soil 63 (1981), S. 77-81 
    Details
    ISSN: 1573-5036
    Keywords: Root growth ; Root morphology ; Root function ; Phosphate supply ; Mechanical resistance ; Zea mays
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Conclusions The influence of mechanical soil resistance on shoot growth can be explained qualitatively by its influence on root morphology. When relating ion uptake quantitatively to a certain root parameter (length, surface area, weight), availability of nutrients in the different soil layers must be taken into consideration.

    Effect of zinc and phosphorus on the grain yield of corn (Zea mays L.) grown on a calcareous soil (1981)

    Notes: Summary In a field experiment, more than 22% increase in the grain yield of corn was obtained by the application of 50 kg ZnSO4/ha. Grain yields were also increased by increasing the level of applied phosphorus. Positive relationship was obtained between Zn and P, the phosphorus treatment increased Zn uptake by grains and vice versa.
