    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.

    Notes: Summary The effect of increasing rates of nitrogen (N) and sulphur (S) as fertilizers on the yield, leaf area and N, P, S, Ca, Mg, NO3 − and SO4 = content in leaves of bean (Phaseolus vulgaris, L.) were studied in a hydroponic culture experiment under greenhouse conditions. Bean plants responded significantly to all treatments with differents N/S ratios. When plants grew with high N/S ratios, the leaf content of N, Ca and NO3 − increased while the content of K, P and SO4 = decreased. However, optimal yield and leaf area were not obtained. Optimal leaf and fruit dry matter was obtained at N/S ratio value of 1.41. When lower N/S rates were used, optimal leaf and fruit dry matter was only observed when the leaf N/S ratio was between 15 and 16. At high sulphate levels in the nutrient solution there is no interaction with nitrate which is easily observed, resulting in an increase in yield. An interaction between nitrate and sulphate in the nutrient solution was found at a N/S ratio of 0.81 which produced in leaves a synergic effect between P-K, an antagonistic effect between N-P and N-K and a lower yield.

    Response of irrigated dry-seeded rice to nitrogen and phosphorus in a semi-arid environment (1982)
    Springer
    Plant and soil 65 (1982), S. 429-432

    ISSN: 1573-5036
    Keywords: Dry-seeded rice ; Nitrogen ; Oryza sativa L. ; Phosphorus ; Semi-arid environment

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Under semi-arid conditions, three field experiments were conducted at Gezira Research Station to determine response of irrigated dry-seeded rice (Oryza sativa L. var IR 2053-206-1-3-6) to addition of nitrogen and phosphorus fertilizers. The experimental treatments included the factorial combinations of seven levels of nitrogen applied as urea and four levels of phosphorus applied as super phosphate. Plant growth and grain yield were significantly and progressively increased with the rise in the levels of added nitrogen and phosphorus. However, response to added phosphorus was restricted by the applied level of nitrogen. The responses of grain yield to nitrogen and phosphorus levels are given by quadratic regression equations. Without addition of nitrogen or phosphorus grain yield averaged 1.52 t/ha compared to 6.07 t/ha with addition of the optimal levels (160 kg N plus 35 kg P/ha). The high potential for rice production in semi-arid environment is evidently restricted by addition of relatively high rates of nitrogen and phosphorus.

    Description / Table of Contents: Resumen El uso mas eficiente de los recursos nitrogenados del mundo que llevará a una mayor productividad vegetal depende de las investigaciones que (a) aumenten la eficiencia económica del uso de nitrógeno en los ecosistemas, (b) hagan mas efectivo el uso del nitrógeno dentro del ambiente de las plantas y (c) reduzcan las pérdidas de nitrógeno mas allá de la zona radical. Los estudios del balance de nitrógeno pueden servir para identificar lagunas en el conocimiento de los procesos del ciclo de nitrógeno.
    Notes: Abstract The more efficient management of the world's nitrogen resources, leading to greater plant productivity, depends on research which (a) improves the economic efficiency of nitrogen inputs into ecosystems, (b) makes more effective use of the nitrogen within the plant environment, and (c) reduces nitrogen losses, particularly from the root region. Ecosystem nitrogen budget studies can emphasize gaps in knowledge of nitrogen cycle processes.

    Description / Table of Contents: Resumen Las sabanas ocupan alrededor de 300 millones de hectáreas de Sudamérica. Los suelos son básicamente oxisoles y ultisoles de muy baja fertilidad y alta acidez. La vegetación natural varía en densidad y en la cantidad de biomasa producida anualmente, la cual puede llegar a ser igual a la producida por bosques de la región. Entre los microorganismos fijadores de nitrógeno, los únicos bien estudiados son las bacterias del género Rhizobium. En el manejo de la biomasa de estas áreas, es importance considerar la fijación del nitrógeno, como una fuente posible que reemplace al que fué exportado en las cosechas. La nitrificación y la denitrificación en estos, es intensa pero no bien estudiada. La distribución de lluvias durante la estación de crecimiento parece tener una influencia considerable en la provisión de nitrógeno de los suelos. Se registran considerables pérdidas de nitrógeno en este ambiente, cuando amplias áreas son quemadas anualmente.
    Notes: Abstract Savannas cover about 300 million hectares of South America. The soils are mainly oxisols and ultisols and their natural fertility is very low with high acidity. The natural vegetation varies in density and in the amount of biomass produced annually, which can be equal to that produced by forests in the region. Among the nitrogen-fixing micro-organisms, the only ones well-studied are Rhizobium bacteria. In managing the biomass in these areas, it is important to consider biological nitrogen-fixation as a possible source of nitrogen to replace that removed in crops. Nitrification and denitrification in these soils are intense but not well studied. The rainfall distribution during the growing season seems to have a considerable influence of the nitrogen supply to the soils. A considerable loss of nitrogen occurs in this environment when vast areas are burned annually.

    Notes: Summary Lowland rice (RD 3) was cultivated in containers of clay soil submerged with 5 cm water under controlled conditions in the phytotron. Deep placement of urea supergranules 5 cm in the soil significantly enhanced both plant growth and fertilizer efficiency when the plants were cultivated under high light intensity (70 Wm−2). At the highest urea level grain yield increased 119% above the control level, while growth and fertilizer efficiency was not as high when deep placement of calcium nitrate was used. The application of urea prills and calcium nitrate (18.4g Nm−2) in two split doses on the soil surface increased grain yield as much as 91% above the control level. At the lower nitrogen concentration (9.2 g N m−2), the urea prills were more efficient than calcium nitrate as indicated by the grain yield. The height of those plants fertilized by surface application was affected by the concentration and not the type of fertilizer. The number of tillers, however, was significantly higher on urea fertilized plants. When the rice plants were cultivated under low light intensity 930 Wm−2), neither the nitrogen fertilizers nor the method of application had a significant effect on growth and yield.

    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.

    Copper nutrition of wheat in relation to nitrogen and phosphorus fertilization (1982)
    Springer

    Notes: Summary In a pot culture study, copper addition to soil increased the crop yield only in presence of nitrogen. The latter increased the utilization of both native as well as applied copper but more that of applied. It also minimised the adverse effect of applied phosphorus on copper utilization. Phosphorus at the rate 45 ppm had the tendency of decreasing copper uptake by wheat if applied without nitrogen or with its low level.

    Notes: Summary The objective was to measure the competition for nitrogen among vascular plants, mosses, and soil microbes along a continuum of nitrogen availability, induced by carbon and nitrogen amendments, in a tussock tundra ecosystem.15N was used as a tracer. Vascular plants showed an increasing15N recovery with increasing time and with increasing nitrogen availability; the latter suggests that nitrogen was limiting vascular plant growth. Green mosses took up15N initially, but showed no significant trends with either treatment or time. There was a higher15N recovery in the soil insoluble compartment for the carbon-amended treatment than in the nitrogen-amended treatments; this suggested that carbon as an energy source limited microbial activity. After two months, the relative15N recovery fell in the order: soil microbes (≈79%)〉vascular plants (≈16%) 〉green mosses (≈2%).

    Notes: Summary The effect of mineral nitrogen on establishment and activity of symbioses between soybean and several strains ofRhizobium japonicum and on the establishment of nodules ofR. japonicum isolated from nodules of field crops is studied. All strains were highly susceptible to the effects of 200 ppm NO3−N on the establishment of symbiosis; 50 ppm NO3−N had little effect. Response of symbioses establishhed in the absence of mineral N to short term exposure to nitrate or ammonium varied significantly between strains. Nodule isolates from soybean crops growing in nitrifying soil were no less susceptible to the inhibitory effects of mineral N on nodule formation than a laboratory culture of the commercial inoculant strain.
