Copper in plant species in a copper gradient in Catalonia (North East Spain) and their potential for phytoremediation
Plant and Soil - 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...
Cereal/legume rotation effects on cereal growth in Sudano-Sahelian West Africa: soil mineral nitrogen, mycorrhizae and nematodes
Plant and Soil - Tập 218 Số 1 - Trang 103-116 - 2000
Yield increases of cereals following legumes in rotation have been previously
reported for West Africa, but little progress has been made to explain the
mechanisms involved. At four sites in Niger and Burkina Faso, field trials with
pearl millet (Pennisetum glaucum (L.) R. Br.), cowpea (Vigna unguiculata (L.)
Walp), sorghum (Sorghum bicolor (L.) Moench) and groundnut (Arachis hypogaea L.)
were con...
Nitrogen fixation and N contribution by promiscuous nodulating soybeans in the southern Guinea savanna of Nigeria
Plant and Soil - Tập 195 Số 2 - Trang 257-266 - 1997
Attention is being paid to improving the N2 fixation of promiscuous nodulating
soybeans in an attempt to develop sustainable cropping systems in the moist
savanna. There is however a dearth of reliable estimates of N2 fixation by these
promiscuous soybeans and hardly any quantitative information is available on
their residual N benefits to subsequent cereal crops grown in the southern
Guinea savan...
Opportunity costs for maize associated with localised application of sewage sludge derived fertilisers, as indicated by early root and phosphorus uptake responses
Plant and Soil - Tập 406 Số 1 - Trang 201-217 - 2016
Phosphorus recycling from waste and localised placement of fertilisers can
potentially improve sustainable P management in agriculture. However, knowledge
about root and plant P uptake responses to placement of complex waste-derived
fertilisers is lacking. Sewage sludge (SS) and sewage sludge ash (ASH) were
tested against triple superphosphate (TSP) in a rhizobox setup where maize shoot
and root g...
Evaluation of the nitrogen nutrition status of rice by plant analysis
Plant and Soil - - 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...
Phosphorus Transformations in an Oxisol under contrasting land-use systems: The role of the soil microbial biomass
Plant and Soil - 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-...
Arbuscular mycorrhizal symbiosis on serpentine soils: the effect of native fungal communities on different Knautia arvensis ecotypes
Plant and Soil - - 2011
Serpentine soils represent a unique environment that imposes multiple stresses
on vegetation (low Ca/Mg ratios, macronutrient deficiencies, elevated heavy
metal concentrations and drought). Under these conditions, a substantial role of
arbuscular mycorrhizal (AM) symbiosis can be anticipated due to its importance
for plant nutrition and stress alleviation. We tested whether serpentine and
non-serp...
Nutrient availability and leaching in an archaeological Anthrosol and a Ferralsol of the Central Amazon basin: fertilizer, manure and charcoal amendments
Plant and Soil - Tập 249 Số 2 - Trang 343-357 - 2003
Soil fertility and leaching losses of nutrients were compared between a Fimic
Anthrosol and a Xanthic Ferralsol from Central Amazônia. The Anthrosol was a
relict soil from pre-Columbian settlements with high organic C containing large
proportions of black carbon. It was further tested whether charcoal additions
among other organic and inorganic applications could produce similarly fertile
soils as...
Improved legume-rhizobium symbiosis by inoculating preceding cereal crop with rhizobium
Plant and Soil - - 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
Plant and Soil - 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 ...
