Provision of N, P, and Ca to field plants of A. linearis markedly (P<0.05) increased growth and N nutrition in a very acidic nutrient-poor soil. Application of P and Ca promoted a significant increase in %N derived from fixation and amounts of N fixed compared to those receiving no nutrients. N2 fixation measured under field conditions ranged from 3.8 g N plant-1 in unfertilized control to 7.1 g N plant-1 in fertilized plants. Overall, about 85% increase in N2 fixation was observed with P…

Does P deficiency affect nodule bacterial composition and N source utilization in a legume from nutrient-poor Mediterranean-type ecosystems?
Use of the 15N natural abundance technique to quantify biological nitrogen fixation by woody perennials
TLDR
While the natural abundance technique appears to provide quantitative measures of BNF in tree plantation and agroforestry systems, particular difficulties may arise which can often limit its application in natural ecosystems.
Plant growth and N2 fixation in Cyclopia longifolia (Vogel L.) supplied with mineral nutrients in pot and field experiments
Nitrogen nutrition, carbon accumulation and δ13C of Cyclopia and Aspalathus species in different settings of the Cape fynbos, South Africa
TLDR
Assessment of the effect of plant age, plant species, toposequence, planting material and farmer practice on nitrogen (N) nutrition and water-use efficiency of two Cyclopia and Aspalathus species in the Cape fynbos found symbiotic N nutrition andWater- use efficiency of Cyclopian and AsPalathus were related.
Accumulation of phosphorus and carbon and the dependency on biological N2 fixation for nitrogen nutrition in Polhillia, Wiborgia and Wiborgiella species growing in natural stands in cape fynbos, South Africa
Species of the genera Polhillia, Wiborgia and Wiborgiella are endemic to the Cape fynbos, South Africa. These plants form root nodules with soil rhizobia that fix atmospheric nitrogen. Little is…
Variable P supply affects N metabolism in a legume tree, Virgilia divaricata, from nutrient-poor Mediterranean-type ecosystems.
TLDR
The roots and nodules of V. divaricata metabolised N differently during P stress, meaning that these organs may contribute differently to the success of this plant in soils from forest to fynbos.
The effects of phosphorus (P) deficiency on growth and nitrogen fixation of Virgilia trees from the Cape Floristic Region (CFR)
TLDR
This study showed that during prolonged P deficiency, V. divaricata showed clear adaptive features during P-deficiency, as it maintained its growth respiration and V. oroboides showed a decrease in nutritional concentrations, which resulted in the decrease of symbiotic nitrogen fixation (SNF).
Phosphorus and Nitrogen Interactions in Field-Grown Soybean as Related to Genetic Attributes of Root Morphological and Nodular Traits
TLDR
The results indicated that all morphological and nodular traits measured continually segregated in the RIL population with a normal distribution of the phenotypic values, indicating that these traits are possibly controlled by quantitative trait loci (QTLs).
RESPONSES OF RHIZOBIUM-INOCULATED AND NITROGEN-SUPPLIED COWPEA PLANTS TO INCREASING PHOSPHORUS CONCENTRATIONS IN SOLUTION CULTURE
TLDR
Metabolic constraints for ureide degradation in leaves seem to be the mechanism underlying the poor response of plants to rhizobial inoculation at high Pc, and the P7 and P8 concentrations proved to be toxic for R+ and N+ plants.
Full Length Research Paper - Nodulation and growth response of Sesbania sesban (L.) Merr. to increasing nitrogen (ammonium) supply under glasshouse conditions
TLDR
It is demonstrated that S. sesban seedlings are tolerant to relatively high levels of N, and that treatment with 100 mg N/l (20 mg N per week) is necessary to stimulate an early and effective N2-fixing symbiosis.

The natural abundance of 15N in an irrigated soybean crop and its use for the calculation of nitrogen fixation
TLDR
Despite large differences in plant size due to plant spacing, S15N in mature nonnodulated plants did not differ significantly, indicating that the natural abundance of 15N in plantavailable soil nitrogen was uniform in root zones of different sizes.
Nitrogen-fixation and nutrient relations in savanna woodland trees (Tanzania)
TLDR
The concentrations of nutrients in leaves and the relations between them indicate that N limits growth in non-N2- fixing species at most sites, while P is limiting in N2-fixing species.
Evaluation of N2-fixation and nitrogen economy of a maize/cowpea intercrop system using15N dilution methods
TLDR
Good agreement was obtained between estimates of N2 fixation of sole or intercrop cowpea (1984/85 season) based on the15N natural abundance and15N fertilizer dilution techniques, both in the field and in a glasshouse pot study.
Effect of reference plant on estimation of nitrogen fixation by subterranean clover using 15N methods
TLDR
The reference plant can induce real changes in P by influencing the soil N status, in the association, as well as causing erroneous estimates of P by the 15N isotope technique.
An evaluation of 15N methods for estimating nitrogen fixation in a subterranean clover-perennial ryegrass sward
TLDR
Yield-independent and yield-dependent methods gave similar estimates of P, and during winter, there appeared to be loss of 15N from the plants, possibly because of loss of highly labelled plant parts, balanced by slow growth of tissue containing a lower 15N concentration.

Involvement of Phosphorus in Nitrogen Fixation by Subterranean Clover (Trifolium subterraneum L.)
TLDR
It is concluded that increasing phosphorus supply increases nitrogen fixation in subterranean clover by stimulating host plant growth rather than by effects on either rhizobial growth and survival or on nodule formation and function.
Estimates of N2-fixation from variation in the natural abundance of 15N in Sonoran desert ecosystems
TLDR
It is concluded that N2-fixation is very important to Prosopis at six of seven sites in the Sonoran Desert and at the site where prosopis did not appear to be fixing N2, N2 -fixation was important only for legumes of the sub-family Papilionoideae.
Nitrogen Nutrition and Xylem Transport of Nitrogen in Ureide-producing Grain Legumes.
TLDR
All species showed higher proportions of organic nitrogen as ureide and several-fold lower ratios of asparagine to glutamine in their xylem sap when relying on N(2) than when utilizing NO(3), and the biochemical significance of the above differences was discussed.
