    Notes: Summary Fertility levels in soils beneathPinus caribaea trees were examined in the Mountain Pine Ridge savannas, Belize, where fire control has precipitated the development of pine woodland. Slight surface soil enrichment was recorded beneath pine canopies, but to levels well below those found beneath associated hardwoods. Estimates of total nutrient pools beneath trees showed modest cation accumulation beneath a 73 year old tree but some defecits in Ca and Mg beneath a 24 year old tree. A tap root cutting experiment on trees of the same species revealed no significant declines in foliar nutrient levels after 19 months. It is concluded that no pronounced long-term deterioration in soil fertility levels is developing beneath stands ofP. caribaea in the savanna, although some temporary nutrient declines may exist beneath young pine stands. Atmospheric inputs are the most likely source of nutrient accretion and it is suggested that the establishment of hardwood associates with pine may enhance the rates of nutrient capture from this source.

    Nutrient accumulation byPinus caribaea in its native savanna habitat (1982)

    Notes: Summary Concentrations of P, N, K, Ca, and Mg in above-ground tissues ofP. caribaea were sampled in the species'native savanna habitat. Concentrations were relatively low, but some evidence of higher consumption of K and Ca was found in trees grown on more fertile soils. Regressions were developed to predict the quantities of nutrients sequestered in above-ground tree tissues, and estimates made of the quantities stored in above-ground stands of this species in its native habitat and in several plantations elsewhere. Estimates were also made of the nutrient removals to be expected by harvesting these stands in different ways. Nutrient quantities stored in stands generally exceed those extractable from savanna surface soils, and it is suggested that inputs from the atmosphere are the most probable alternate nutrient source. A comparison of these inputs for tropical areas with the quantities required for stand growth in the savanna, and harvesting removals, suggests that an adequate supply of all elements except P exists, provided that capture by pine is effective. However, atmospheric inputs generally fall below the storage and harvest removal rates for fast growing exotic plantations of this species suggesting that multiple rotations of these plantations at current growth rates may not be feasible without artifical fertilization.

    Effects of waterlogging on young wheat plants (Triticum aestivum L.) and on soil solutes at different soil temperatures (1982)
    Springer
    Plant and soil 69 (1982), S. 311-326 
    Details
    ISSN: 1573-5036
    Keywords: Aeration ; Calcium ; Carbon dioxide ; Ethylene ; Nitrate ; Nitrite ; Nitrous oxide ; Oxygen ; Potassium ; Roots ; Triticum aestivum ; Waterlogging ; Wheat

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary We report a study of the mechanism by which the response of plants to waterlogging can be modified by soil temperature. Wheat was grown initially in well-aerated soil in a controlled environment room before the soil was flooded with aerated, deionized water. The soil temperature was maintained constant in the range 6–18°C while the air temperature was at 14°C. Waterlogging damage was greater in plants at the higher soil temperatures when the plants were compared at the same chronological age. However, when compared at the same growth stage, the response to soil temperature was little differenti.e. plants subjected to waterlogging for a long time at low soil temperatures exhibited a similar reduction in growth and other properties as those subjected briefly at higher temperatures. The concentration of dissolved oxygen in the soil solution declined rapidly at all temperatures, being almost zero after 36 h waterlogging. Temperature affected rates of change of the concentrations of dissolved carbon dioxide, ethylene, nitrous oxide, nitrite, nitrate, calcium and potassium. The importance of soil-and plant-determined properties in the waterlogging response of plants at different temperatures are discussed.

    Factors of plant nutrient availability relevant to soil testing (1982)
    Springer
    Plant and soil 64 (1982), S. 129-138

    ISSN: 1573-5036
    Keywords: Ammonium ; Buffering power ; Nitrate ; Nutrient availability ; Phosphate ; Potassium
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary In most arable soils the nitrate availability depends mainly on the quantity of nitrate present in the rooting zone at the beginning of the growing season. Easily mineralizable organic N and the release of non-exchangeable NH4 from clay minerals may in addition control the nitrogen availability during a season. In flooded soils, ammonium is the major form of nitrogen absorbed by plants. Ammonium dynamics in these soils is similar to that of potassium. The availability of both is controlled mainly by the intensity and buffering power for ammonium or potassium, respectively. Basically, intensity of the supply and buffering power for phosphate are the main factors determining the phosphate availability. The determination of the phosphate buffer power, especially in the root zone, however, remains to be difficult. Soil test methods should take into consideration the major factors and processes relevant to the availability of a particular plant nutrient.

    Effect of sulfur and potassium on zinc absorption by barley (1982)
    Springer
    Plant and soil 64 (1982), S. 393-401 
    Details
    ISSN: 1573-5036
    Keywords: Barley ; Cysteine ; Potassium ; Sulfur ; Translocation ; Zinc
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Maximum uptake of Zn in barley (Hordeum vulgare L.) seedlings occurred from nutrient solutions containing SO4−S at 3.5 ppm and K at 6 ppm. Decreased translocation of Zn from roots to tips was observed when plants were grown with lower levels of S and K. Cysteine substituted for SO4-ion as a source of S in Zn absorption, and more Zn was absorbed with cysteine than with sulfate. The effect of K on Zn absorption seems to be influenced by S nutrition in plants.

    Response of maize toAzotobacter chroococcum (1982)
    Springer
    Plant and soil 69 (1982), S. 265-273

    ISSN: 1573-5036
    Keywords: Azotobacter chroococcum ; Fertilizers ; Farmyard manure ; Nitrogen ; Nitrogen fixation ; Potassium ; Phosphorus ; Yields of grain stover ; Zea mays
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Field trials were conducted during theKharif seasons of 1979 and 1980 to examine the effect of the nitrogen-fixing bacteriumAzotobacter chroococcum (isolate M4) on yields of maize and N-economy. Different levels of nitrogen and farmyard manure (FYM) were supplied to assess their interaction with Azotobacter inoculation. Seed inoculation without fertilization raised grain and stover yields significantly. FYM coupled with inoculation gave higher yields than either could singly. The financial gain due to an increase in grain yield upon applying per ha 80 kg N, 10×103 kg FYM and Azotobacter over the treatment 40N + FYM + Azotobacter was offset by the cost of the additional N; thus, the higher N-application was not economical. Azotobacter inoculation was economically most efficient at lower doses of fertilizer nitrogen which not only increased yields but resulted in a saving of fertilizer N when applied in combination with FYM.

    Notes: Summary The economic feasibility of using cultures of nitrogen fixing microorganisms in programmes to increase crop production, as a selfgenerating source of nitrogen, has been proved beyond doubtviz. Legume-Rhizobium symbiosis and blue green algal ‘fertilizer’ for rice. The extent to which the free living, N-fixing, aerobic, heterotropicAzotobacter chroococcum could replace the application of nitrogenous fertilizer to maize was investigatedin vivo. Total nitrogen uptake (kg ha−1) by maize after inoculation with Azotobacter combined with moderate applications of nitrogen fertilizer and farmyard manure was influenced significantly and resulted in a higher nitrogen concentration in grain and stover along with a higher yield.

    Notes: Summary The effect of increasing potassium and magnesium fertilization during 15 years on the amounts of K and Mg extracted by AL-solution and desorbed by Electro-Ultrafiltration (EUF) was determined in four Swedish soils. In all soils, with increasing potassium fertilization the amounts of K extracted by AL and desorbed by EUF increased, and the amounts of Mg-AL and Mg-EUF decreased. Magnesium fertilization had no significant effect on the K values but increased both Mg-AL and Mg-EUF. The EUF-values were lower than the corresponding AL-values, but the ratio of EUF-desorbed to AL-extracted amounts of K and Mg varied depending on soil type as well as on fertilization rate. The ratio of K-EUF to K-AL increased and the ratio of Mg-EUF to Mg-AL decreased with increasing potassium fertilization, whereas magnesium fertilization decreased the ratio of Mg-EUF to Mg-AL.

    Notes: Summary Field experiment was conducted during 1980–81 on the Indo-Gangetic alluvial soil of Pura, Kanpur to study the effects of added potassium and zinc on dry-matter production and uptake of these nutrients by potato crop. Increasing supply of potassium and zinc significantly increased the dry-matter production and concentration and uptake of respective nutrients in different crop components. The effects of combined application of potassium and zinc was positive in influencing the dry-matter production and K, Zn uptake by potato crop. Increasing supply of potassium showed beneficial effect on the absorption and translocation of zinc in plant system indicating thereby greater utilization of fertilizer zinc by the crop. Increasing supply of zinc, however, could not influence the concentration of potassium.

    Notes: Summary The concentration, uptake and element use efficiency of N, P and K in one C3 annual (Polypogon monspeliensis) and two C4 (Echinochloa colonum, an annual, andDichathium annulatum, a perennial) grasses were determined during winter and summer seasons in monocultures raised in field plots at three moisture levels,viz. full, half and one-fourth of field capacity. At each moisture regime the plants were clipped thrice at moderate and severe levels corresponding to 40 and 80% of live green. The concentration of these elements was characteristic of the growth habit of these plants;e.g. the build up of concentration was maximum in leaf of the annuals while it was comparable in crown and leaf of Dichanthium. The N level was maximum in Polypogon. The nutrient use effiency was comparable in the two annuals and maximum K and N use were obtained in Polypogon and Dichanthium, respectively.
