Plant nutrition research: Priorities to meet human needs for food in sustainable ways
Tập 247 Số 1 - Trang 3-24 - 2002
The world population is expanding rapidly and will likely be 10 billion by the year 2050. Limited availability of additional arable land and water resources, and the declining trend in crop yields globally make food security a major challenge in the 21st century. According to the projections, food production on presently used land must be doubled in the next two decades to meet food demand of the ......
Phosphorus Transformations in an Oxisol under contrasting land-use systems: The role of the soil microbial biomass
Tập 237 Số 2 - Trang 197-210 - 2001
It is generally assumed that phosphorus (P) availability for plant growth on highly weathered and P-deficient tropical soils may depend more on biologically mediated organic P (Po) turnover processes than on the release of adsorbed inorganic P (Pi). However, experimental evidence showing the linkages between Po, microbial activity, P cycling and soil P availability is scarce. To test whether land-......
Copper in plant species in a copper gradient in Catalonia (North East Spain) and their potential for phytoremediation
Tập 230 Số 2 - Trang 247-256 - 2001
The accumulation of Cu in roots and shoots of 32 plant species growing on soils with a wide range of Cu concentrations (30–18 500 μg g−1 total soil Cu) located in Collserola Mountain (Barcelona, Spain) was analysed. High Cu availability decreased the species diversity in the Hyparrhenietum hirto-pubescentis, the natural plant association at the study sites. Shoot and root Cu concentrations in rela......
Stabilization mechanisms of soil organic matter: Implications for C-saturation of soils
Tập 241 Số 2 - Trang 155-176 - 2002
The relationship between soil structure and the ability of soil to stabilize soil organic matter (SOM) is a key element in soil C dynamics that has either been overlooked or treated in a cursory fashion when developing SOM models. The purpose of this paper is to review current knowledge of SOM dynamics within the framework of a newly proposed soil C saturation concept. Initially, we distinguish SO......
Citrus root responses to localized drying soil: A new approach to studying mycorrhizal effects on the roots of mature trees
Tập 206 Số 1 - Trang 1-10 - 1999
Because fine roots tend to be concentrated at the soil surface, exposure to dry surface soil can have a large influence on patterns of root growth, death and respiration. We studied the effects of arbuscular mycorrhizas (AM) formation on specific root length (SRL), respiration and mortality of fine roots of bearing red grapefruit (Citrus paradisi Macf.) trees on Volkamer lemon (C. volkameriana Tan......
Improved legume-rhizobium symbiosis by inoculating preceding cereal crop with rhizobium
- 1980
In cereal-legume crop rotation system, better Rhizobium symbiosis was obtained by double inoculation,i.e., when the preceeding cereal crop of maize was also inoculated with the same Rhizobium strain, used to inoculate the following legume crop of green gram or groundnut.
Nitrous oxide emissions following application of residues and fertiliser under zero and conventional tillage
Tập 254 Số 2 - Trang 361-370 - 2003
Emissions of N2O were measured following combined applications of inorganic N fertiliser and crop residues to a silt loam soil in S.E. England, UK. Effects of cultivation technique and residue application on N2O emissions were examined over 2 years. N2O emissions were increased in the presence of residues and were further increased where NH4NO3 fertiliser (200 kg N ha−1) was applied. Large fluxes ......
Evaluation of the nitrogen nutrition status of rice by plant analysis
- 1972
The results of a greenhouse and a field experiment to evaluate the nitrogen nutrition status of rice indicate that: (1) first and second most recently natured leaves are sensitive indicators of the nitrogen status of plants; (2) the total nitrogen concentration in these leaves are a better indicator of the nutrient status of plants than are the water-soluble and amide-plus-ammonium nitrogen fracti......
Nutrient supply and fertilizer experiments in view of N saturation
- 1990
New types of forest damage associated with Mg (and K) deficiency can be corrected by proper fertilization using fast release Mg (and K) fertilizers or Mg limestone. Sufficient Mg and K supply provided by former fertilizer applications inhibited the appearance of typical deficiency symptoms in areas where unfertilized control trees are now characterized by yellowing. In these areas N input rates va......
Legumes have a greater effect on rhizosphere properties (pH, organic acids and enzyme activity) but a smaller impact on soil P compared to other cover crops
Tập 394 Số 1 - Trang 139-154 - 2015
Plants affect phosphorus (P) cycling through uptake and the mobilization of P from several soil pools into soil solution. The effects of seven cover crop species – three legumes (variable morphology), three cereals (variable domestication degree), one mustard (non-mycorrhizal) – on P cycling were compared in a greenhouse experiment. Monocultures and legume-cereal mixtures were grown in an artifici......
